Rotolin Type MCR Ball retaining cages

In applications where the design requires only a ball cage assembly, the MCR cages are recommended. Standard materials are brass and aluminium. Balls are manufactured from 535 A99 steel. Shaft and housing should be hardened to at least 60 HRC and ground to at least 0.25nm. It is therefore important that the dimensions for the shaft (Bs) and for the housing (Dh) be followed so the function of the entire bearing will be equal to that of the standard Rotolin Bearings.

Special Retaining Cages: We are equipped to meet your requirements for special retainer cages in any size, any material or any configuration. Please call or email us if you have a requirement which our standard cages do not fulfil. If a shaft or housing is required please contact us to discuss your needs

A representative (imperial) range is shown below. Metric sizes, specials to drawing or sample can be manufactured.  Please contact us to discuss your requirements.
