Precision Thin Section Bearings are Special Inspection Appropriate measuring equipment must be used which will allow the inspector to take 3 to 5 readings around the circumference which are then averaged to determine the true measurement of the bearing in the free state (unmounted). This procedure allows for the inherent out-of-roundness these bearings will exhibit. When measuring these bearings, special care must be exercised to ensure neither the bearing weight or pressure from the measuring equipment affects the measurements. Installation Lubrication |
Load Ratings Housing & Shaft Fits Thin Dense Chrome Plating We apply this plating to our standard 52100 steel inner and outer rings so allowances must be made to standard housing and shaft fits to allow for the plating build up on the exposed surfaces, especially the bore and outside diameter. The plating build up per surface can generally be from .000040 inch to .00015 inch. Contact Silverthin Bearing for bore and shaft fits. |
