RSL182311-A Cylindrical Roller Bearing
Selection Guide
RSL full-complement cylindrical roller bearings achieve the maximum radial load capacity available in a given section by filling the annulus with rollers and omitting the cage, suiting low-speed heavy-load duty where speed is not the limiting factor and capacity is the primary concern. Verify that the actual operating speed is below the permissible value for that size (a full complement design has clearly lower speed capability than a caged type), that lubrication is generous, and how axial location is handled (most full complement types need separate thrust or locating elements). If your speed is relatively high we recommend a caged cylindrical roller bearing to avoid sliding wear between rollers.

RSL182311-A How do I choose between a full-complement and a caged cylindrical roller bearing?
Decide from the combination of speed and load. For low-speed heavy-load duty such as gearbox support rolls, drums and travel reducers, choose full complement for maximum radial capacity. Where speed is higher, or the load includes shock and needs better roller guidance, choose a caged type: the cage separates the rollers, friction and heat generation are lower, and limiting speed is much higher. As a rule of thumb, prefer a caged design when the dn value is high or when there are frequent starts and stops or reversing loads. Give us speed, radial load and duty cycle and we will give a clear recommendation.
RSL182311-A What should I watch for when mounting a full-complement cylindrical roller bearing?
In a full complement design the rollers are not retained by a cage and can fall out, so the bearing must be handled and fitted as a complete unit, kept level, and never dismantled into separate rings. Never strike the roller end faces — press on the ring using a suitable sleeve. Because adjacent rollers slide against each other, lubrication must be generous and clean: before first running, fill with the specified grease or confirm the oil path is clear to avoid early wear from dry friction.
