External Support for Our Sprag Elements

RL Series Use our RL roller bearings to keep GMN Sprag Insert Elements concentric to the shaft and housing. The RL series is meticulously optimized to use the same shaft and housing dimensions as the FE series – lowers machining costs!

If you are thinking of using the RL series for our FR / FRN sprag elements with mounting rings, please contact our onsite engineers to help you calculate the correct RL size for your shaft and housing assembly.
