In the case of bearing arrangements which

work in very limited space, , needle roller

bearings are frequently used without inner

rings, designation. In these cases the bearing

needles run directly on the shafts surface.

these running surfaces, however, must to be designed to the same quality standard as for

bearing rings,. since needle roller bearings allow for length compensation of a certain amount

within the bearing, they are optimum as non locating bearings.

we supply high quality rollers with hardened

steel,all of the rollers had hardened. usually,

the material of needle rollers and cylindrical

rollers, is chrome steel 52100(HRC60-65) or

stainless steel 420 (HRC53-56), the material of balls, is stainless steel

440C(HRC55-58).

in both inch and metric sizes. we also custom manufacture special dowel pins to your

specification, and will be pleased to offer our quotation upon receipt of your detailed

requirements.
