REALI-SLIM® Bearings Catalog 300 ©KAYDON® Corporation Issue 10 ULTRA-SLIM® Thin-Section Bearings Ideal for applications in robotics, inspection equipment, satellites, cameras… anywhere precise positioning and lightweight designs are critical. At just 2.5 mm wide, ULTRA-SLIM® bearings are available in bore sizes ranging from 35 mm to 170 mm for an array of applications. Their compact profile allows you to use ULTRA-SLIM® bearings in many highly confined spaces. Precision-engineered ULTRA-SLIM® bearings are made of stainless steel for corrosion resistance. They are available in angular contact (Type A), radial contact (Type C), and fourpoint contact (Type X) styles. (See selection charts at right.) Hybrid bearings with ceramic balls are available upon request. These configurations are used often when lubrication is marginal or when lower wear generation and/or lower torque levels are required. Figure 2-11 How to identify ULTRA-SLIM® Bearings using our part number code Position Explanation of position numbers: Position 1—Material S = AISI 440C races and balls (Standard for Series) A = Angular Contact C = Radial Contact X = Four-Point Contact Nominal bearing bore in mm. Positions 5 and 6—Width S = Spacer balls F = Full complement of load balls Nominal radial race width in mm. Position 10—Internal Fit A = 0.000 - 0.013 mm clearance C = 0.013 - 0.025 mm clearance E = 0.025 - 0.051 mm clearance K = 0.000 - 0.013 mm preload M = 0.013 - 0.025 mm preload empty = tandard internal fitup if not specified s Position 9—Precision 0 = KAYDON standard precision class Performance and Application Considerations 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 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.
