INA from Schaeffler bearings have solid outer and inner rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have high radial load carrying capacity, high rigidity and are suitable for compact designs. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage. Cable sheave bearings (cylindrical roller bearings with snap ring grooves) are locating bearings. These bearings are rigid and can support moderate axial forces in both directions and high radial forces. They consist of solid outer and inner rings with ribs, rib-guided cylindrical rollers and sealing rings.
The outer rings have snap ring grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and held together by a rolled-in steel strip.

• Lower operating costs • Reduced maintenance due to improved lubrication
• Lower heat generation
• Less noise
