Summary Information
Lightweight Stainless Steel UltraSlim Thin Section Bearings

Lightweight Stainless Steel UltraSlim Thin Section Bearings are low profile, large bore bearings that are destined to change your thinking about robotics, inspection equipment, satellites, cameras and similar applications where precise positioning and lightweight designs are critical.

At just 2.5mm wide, Ultra-Slim bearings are available in bore sizes ranging from 35mm to 170mm for an array of applications requiring compact motion control design components.

Precision-engineered Ultra-Slim bearings are made of stainless steel for corrosion resistance. Hybrid versions with ceramic balls are available upon request. Ultra-Slim bearings are available in angular contact (Type A) radial contact (Type C), and four-point contact (Type X) styles.

Need something other than lightweight stainless steel, hybrid bearings with ceramic balls are available upon request. These configurations are used often when lubrication is marginal or whenlower wear generation and/or lower torque levels are required.

Performance and application considerations for lightweight stainless steel thin section bearings:

Ultra-Slim bearings are unique in that their extremely thin cross section enables them to provide great size and weight reductions for light to medium duty applications with slow or intermittent rotation.

Given the fact that these bearings will most likely be used in lightly loaded applications where saving weight and space are the main objective, the loading values shown assume that the shaft and housing will also be of a light construction. This will allow for greater bearing ring movement under load than traditional heavy section bearings. Thus the loading limits for capacity are not based on ABMA standards.

Depending on the support provided by the shaft and housing, this movement can create increased stress levels within the bearing. Distortion of the shaft and housing under load will transfer to the bearing, causing increased stress levels which could lead to premature failure and/or erratic torque conditions.

The impact of non-uniform shaft and housing distortions is best found by testing. If problems are experienced, increased rigidity of the shaft and housing may be necessary. If the shaft and housing are of sufficient rigidity, it may be possible for the bearings to support greater loads than the loading limits provided.
