Roller Bearings

Tapered Roller Bearings Tapered roller bearings are a very diverse style of bearing as they can be used in many different combinations of loads depending on the construction of the bearing assembly Bearing components include an inner ring or cone an out ring or cup and tapered rollers that are spaced and contained by a cage

Needle Roller Bearings

Depending on the application bearings or needle roller and cage assemblies without inner ring can be used The journal surface and the housing hole surface that match the bearing directly serve as the inner and outer rolling surfaces of the bearing to ensure load capacity and running performance As with ferrule bearings

Mounting of drawn cup needle roller bearings

needle roller bearings The mandrel normally rests against the stamped end face of the bearing which is hardened in the case of smaller bearings Even if the bearing is pressed in via an unhard-ened rib this will not lead to deformations or jamming of the needle roller and cage assembly as long as the mandrel is correctly dimensioned
