TIMKEN 378RYSL1963 CRB <36 OD Long Product

Timken’s four-row cylindrical roller bearings are designed for the rigors of daily use in applications where moderate and high speeds, high radial loads, elevated temperatures and debris are constant challenges. Designed with well-balanced cross sections, these bearings provide high-radial-load capacity within the bearing envelope.
The radial internal clearance (RIC) for the bearing assembly must be included when ordering either a) the complete assembly or b) with the inner-ring set. It is advisable to order the inner-ring set independent of the outer ring set when the final grind of the inner-ring O.D. is accomplished after mounting on the roll neck.
The RY bearing style incorporates two outer races with triple flanges (solid ribs). The inner race is usually single-piece construction. The outer assemblies consist of the outer race, rollers and cages, which create a unitized construction. Handling is made simple by this design. A loading slot is used for roller insertion. Lubrication is generally accomplished via slots in the faces of the outer ring. The cage is single-piece, fully machined brass or steel material. The roller pockets are staggered between the races.

• Two outer rings with integral ribs.
• Two inner rings.
• RY-2 – with lubrication grooves and holes on outer rings.
• RY-3 – without lubrication grooves and holes on outer rings.
