Sealed spherical roller bearings
Features Spherical roller bearings are double row, self-retaining units com-prising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings have cylindrical or tapered bores.The symmetrical barrel rollers orient themselves freely onthe concave outer ring raceway. As a result, shaft flexing and misalignment of the bearing seats are compensated.Sealed spherical roller bearings are characterised by:■ very high basic dynamic and static load ratings■ lower frictional torque compared to the competition■ environmentally friendly characteristics■ lower grease consumption and disposal costs■ no requirement for expensive relubrication systems■ reduced maintenance outlay■ simple reconditioning of series 240 and 241■ longer operating life of the bearing.Sealed spherical roller bearings are suitable for areas of operation such as continuous casting plant, conveyor belts, elevator plant or the food industry.
Spherical roller bearings of the X-life design have improved kinemat-ics and optimised surfaces, are made from higher performance materials and do not have a rigid central rib. As a result, the basic dynamic and static load ratings and, under identical operating conditions, the basic rating life of the bearings are significantly improved. In certain applications, this means that a smaller bearing arrangement can be designed.X-life spherical roller bearings have the suffix E1.

Sealing concepts The sealed spherical roller bearings are fitted, depending onthe series, with different sealing concepts.
Spherical roller bearingsof series 222, 223, 230, 231, 232
Features of the sealing concept of sealed spherical roller bearing series 222, 223, 230, 231, 232 are as follows:■ bearings with an oversize width are identified by the suffix WS
(WS = Wide Size). As standard, this affects the series 222 and 223. Example WS22215-2RSR. The remaining sealed spherical roller bearings of the series 222, 223, 230, 231 and 232are allocated an F-number and have the main dimensions ofthe specific open type
■ solid brass cage or sheet steel cage■ greasing with a lubricant KP2K–20 in accordance with DIN 51502
recommended by FAG for a temperature rangeof –20 °C to +130 °C; other greases are available by agreement
■ 25% to 40% grease fill level of the bearing interior;different grease fill levels are available by agreement
■ dimensional stabilisation up to +200 °C (standard)■ radial internal clearance CN■ self-alignment facility 0,5° from the central position■ limiting speed ng dependent on the grease and grease fill level■ contact seals made from nitrile rubber (NBR), suitable for
temperatures of –40 °C to +100 °C (suitable for short periodsup to +120 °C); other sealing washer materials (such as fluoro rubber (FKM)) are available by agreement.
Seals made from fluoro rubber (FKM, FPM, such as Viton®) comprise particularly high performance materials that may release vapour when heated to approx. +300 °C. This may occur if, for example,a welding torch is used in the dismantling of a bearing. In such cases, the appropriate safety data sheet must be observed and this is available upon request.

Features of the sealing concept of sealed spherical roller bearing series 240 and 241 (with the exception of F-803042) are as follows:■ main dimensions identical to those of the open bearing allow
simple interchange■ basic load ratings identical to those of an open bearing■ X-life design■ sealing washers are interchangeable■ internal bearing design with sheet steel cage and loose
central rib■ greasing with a lubricant KP2R–30 in accordance
with DIN 51502 recommended by FAG for a temperature rangeof –35 °C to +180 °C; other greases are available by agreement
■ radial internal clearance CN■ dimensional stabilisation up to +200 °C■ 60% grease fill level of the bearing interior; different grease fill
levels are available by agreement■ limiting speed ng dependent on the grease and grease fill level■ self-alignment facility 0,5° from the central position■ standard design as a completely sealed bearing with a closed
outer ring, suffix H40, see table and Figure 2, page 5■ for simple relubrication, a design is available with a circumfer-
ential groove and three lubrication holes in the outer ring,see table and Figure 3, page 5

The following comparison from the continuous casting sector shows what savings can be made possible by the use of sealed spherical roller bearings instead of open bearings.The grease costs for relubrication of an open bearing and a sealed bearing (seal lubrication of the housing) were taken into consider-ation along with the specific disposal and separation of the grease from the cooling circuit.Due to the lower maintenance outlay and the generally longer lifeof the sealed spherical roller bearing, the higher purchase price compared to the open bearing is recouped after only a short time.An example of the cost ratio in the life cycle of a sealed and an open bearing for a selected bearing position in a bearing position in a con-tinuous casting plant (bearing price for the open bearing = 100%)is shown in Figure 5. The cost ratio and the development over time is decisively dependent on the bearing size.

Rolling bearing reconditioning During the maintenance of machinery and plant, many rolling bearings are taken out of service and replaced by new ones asa precaution. In some cases, this safety-conscious approachblocks any appreciation of the potential cost savings. The fact is: reconditioned bearings generally give the same performanceas new ones.The reconditioning of rolling bearings and rolling bearing units is one of the core competences of the service arm of Schaeffler Group Industrial and is offered at several certified locations worldwide.Our services for rolling bearings of all types apply irrespective of manufacturer and are not restricted to Schaeffler Group products.The Schaeffler Group is in a position to recondition and modify rolling bearings with an outside diameter of up to 4 250 mm, Figure 6. It is thus an expert partner for customers from a very wide range of industrial sectors such as general and special machine building, steel and aluminium, pulp and paper production,wind power, shipbuilding, private and public railways and mining.
Further information ■ Further information on the reconditioning of rolling bearingsis given in Technical Product Information TPI 207, Reconditioning of Rolling Bearings.

Continuous casting plant
In continuous casting plant, the cast strand is supported by rolls.In order to restrict deflection, the rolls are supported at several points along their length by rolling bearings. These bearings are subjected to high loads, low speeds, spray water and high temperatures. Spherical roller bearings of sealed design are usedto support the rolls.
Requirements The demands on the design are:■ high static load carrying capacity■ maximum resistance to the ingress of foreign matter.

Design solution Sealed spherical roller bearings E1 offer a high standard of reliability, cost-efficiency and technical performance capacity inthe metal-producing and metal-processing industry.Due to the particularly compact bearing seals in series 240 and 241, the internal construction used can be the same as in the open type. The advantages of the field tested X-life design are now also access-ible for sealed spherical roller bearings. The external dimensionsof course remain identical to those of the unsealed variant.The extremely reliable sealing arrangement using a high temperature elastomer (FKM) and a special high temperature lubricant allowsa longer bearing operating life, leading to higher machine availability and thus to greater added value.The maintenance-friendly sealing concept of series 240 and 241 also contributes to rapid amortisation.For the specific applications, the grease operating life as well asthe relubrication quantity and the service life must be checked.

Design solution FAG spherical roller bearings are designed for very high loads and facilitate the compensation of misalignments and shaft deflections. Special cylindrical roller bearings are used for the non-driven pulleys that normally have an internal bearing arrangement.Due to the extremely high basic static and dynamic load ratings,the customer requirements are satisfied to an optimum extent.In addition, the sealing of the bearings gives a drastic improvement in reliability and operating life. Even in harsh, dusty environmental conditions, the bearings have the best possible protection against the ingrease of foreign matter. Furthermore, the seals on both sides gives a significant reduction in the grease quantity consumed during operation. The use of high quality grease in the sealed rolling bearing and a biologically compatible grease for sealing the housing increases cost-effectiveness, extends the maintenance intervalsof the conveyor belt and protects the surrounding environment.For the specific applications, the grease operating life as well asthe relubrication quantity and the service life must be checked.

Design solution The extremely reliable sealing arrangement using an elastomer already subjected to field tests allows extended operating life and thus a possibility of approaching freedom from maintenance.The consistently very high basic load ratings of the spherical roller bearings also permits downsizing of existing bearing arrangements or in new designs. We address the increasing requirements inthe travel height and travel speed of elevators using our sealed spherical roller bearings with high basic load ratings and smooth running characteristics.Furthermore, a particularly low noise level can be achieved by ordering specially developed low noise designs.For the specific applications, the grease operating life as well asthe relubrication quantity and the service life must be checked.
