JUMBO COMBINED ROLLER BEARINGS FOR MATING INTO LARGER CONSTRUCTIONAL STEEL PROFILES

The Jumbo combined bearings have been designed for use in heavy duty linear motion applications where it is not possible to use the Standard Combi Bearings because the contact force (Hertzian Pressure) is too high.

All of the Jumbo combined roller bearings have eccentric adjustable side (axial) rollers.

Calculate which size you need using Hertzian Pressure.
