SL Type Cylindrical Roller Bearings for Sheaves  

Rope sheave bearings are full complement cylindrical roller bearings with annular slots and are designed as locating bearings. These bearings are very rigid and can support moderate axial forces in both directions as well as high radial forces. They are particularly suitable for compact designs. The bearings comprise solid outer and inner rings with ribs, rib-guided cylindrical rollers and sealing rings. The outer rings have annular slots for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and held together by a sheet metal ring. Cylindrical roller bearings with annular slots are available in the light series SL04..-PP and in the dimension series 50 as SL0450..-PP. Anti-corrosion coating In order to ensure long operating life and high functional security of rope sheave bearings, coatings matched to the application are indispensable. With its modular coating concept, Schaeffler offers dedicated solutions for the prevention of corrosion and wear. By reducing friction, the coatings contribute to energy efficiency in the form of lower energy consumption. Many of the coatings available in the market are, however, not always suitable and can, if used incorrectly, lead to safety problems. For many years, Schaeffler has successfully supplied cylindrical roller bearings SL04 with the suffix RR for rope sheave applications with the Cr(VI)-free thin layer coating Corrotect.
