Coil Springs

●Operating temperaturesThe load capacities and other data listed in the Catalog are those measured at normal temperatures (40℃ or below).If the working environment temperature exceeds the normal temperature range, the load capacity and durability count may decrease, although this varies depending on a variety of conditions.

●Maximum allowable de� ectionDo not use the springs exceeding the maximum allowable deflection.If used at higher deflections, the spring load capacity and durability will diminish, and in the worst case the spring may break.

●Coating of coil springs ISO 10243Coil springs ISO 10243 are coated for identification and to prevent corrosion.

●Spring load calculation methodLoad = Spring constant × Deflection

Instructions and precautions for the use of coil springs [Technical Data]

■Instructions and precautions for the use of coil springs

①Always use a spring guideIf used without a spring guide, problems such as buckling or bending of the spring body may occur, resulting in concentrated high stress on the inside of the bend and then leading to breakage. Be sure to use a spring guide, such as a shaft or outer diameter guide.※In general the best results are obtained by inserting a shaft all the way through the coil

spring from top to bottom to serve as an inner diameter guide.

②ClearanceSet the shaft diameter following the Rod diameter(d) shown in each spring page. If the clearance with shaft is too small, the spring inner diameter will become worn by the shaft, leading to breakage occurring at the worn points. Set the hole diameter following the Hole diameter(D) shown in each spring page. If the clearance is too small, the outer diameter becomes restrained by expansion on the outer diameter side when the spring is flexed.

③Avoid short guide lengths and shallow counterbore hole depthsIf the guide is too short, the spring may contact the end of the guide when the spring buckles, and the resulting friction may cause the spring to break. The guide length should be to a minimum of 50% of the initial set height. Also be sure to chamfer the shaft to approximately C3. Do not store springs in compressed state for long time as it may cause abnormal fatigue to the springs.

④Do not use in excess of the maximum allowable de�ection（Do not use close to the solid height.）

If the spring is used beyond the maximum allowable deflection, high stress in excess of the calculated value occurs in the cross section. This can cause the spring to break. In addition, if the coil spring is used close to its solid height, the active coils will gradually adhere to each other, increasing the spring constant value and causing the load curve to rise as shown in Fig.1. The resulting high stress may cause the spring to break. This also is a cause of strain. Do not use the coil spring in excess of the maximum allowable deflection.

⑤Set an initial de�ectionIf there is a gap, the spring will move vertically, resulting in an impact force and causing bending of the body or buckling. Setting an initial deflection stabilizes the top and bottom ends of the spring. It is recommended to apply a minimum initial deflection of 5% of the free length.

⑥Do not use when scrap or other foreign substances are caught in the springForeign substances wihch get caught between the coils prevent that part of the coil spring from functioning as an active coil, forcing the other coils to deflect as shown in Fig.2. This effectively reduces the number of active coils, increasing the stress on the spring, and eventually causing it to break. Be careful to prevent scrap or other foreign substances from entering the coils.

⑦Do not use in locations where the the mounting surfaces are not suf�ciently parallelIf the mounting surfaces are insufficiently parallel, bending of the spring body occurs, resulting in concentrated high stress on the inside of the bend that may cause the spring to break. In addition, if the die is not sufficiently parallel, as shown in Fig.3, the spring may break due to bending or to exceeding the maximum allowable deflection. Ensure that the coil spring’s mounting surfaces are as close to perfectly parallel as possible in order to prevent the maximum allowable deflection from being exceeded. When using different type of springs in parallel simultaneously ensure that overall deflection and force guarantee a balanced load.

⑧Do not use coil springs in seriesIf two coil springs are used in series, the springs will bend as shown in Fig.4. In some cases, the spring will ride up on the shaft or counterbore hole, causing breakage by the same mechanism described in①. Variation in the spring load capacities will also result in the weaker spring being overcome by the stronger spring（Fig.5）. This increases the deflection of the weaker spring, resulting in a difference in durability between the springs or else in breakage.In addition, when two springs are used in series, the spring constant of each is reduced by 1/2.

⑨Do not use two coil springs in a double-spring arrangementThe use of two coil springs in a double-spring arrangement, as shown in Fig.6, may result in the inner coils being sandwiched between the outer coils（or vice versa）when the springs buckle. This can cause the coil springs to break for the same reason described in ③.

⑩Do not use the coil spring horizontallyIf the spring is used horizontally, the shaft will cause wear of the spring inner diameter, resulting in breakage at the points of wear.

⑪Do not make any alterations.Any alteration on the surface of the spring (cutting, grinding, scratches,etc.) may significantly reduce the expected lifetime. Always replace the damaged springs with new ones.

⑫Check the real working de�ectionTool maintenance can vary the original working deflection of the springs. Please always check the real working deflection of the springs to avoid early failure of the springs or damages in the tool.
