Installation Simplicity ® Linear Plain Bearings
Installing Simplicity ® Bearings
The recommended installation procedure is to freeze the bearings at 0°F (-17.75°C) for 30-45 minutes. Using gloves, remove the bearings from the freezer and slip them into the housing. As they heat to room temperature, full contact between bearing and housing will be achieved. The greatest advantage to this technique over traditional pressing is greater accuracy in alignment. This type of mounting will not allow for misalignment or shaft deflection. Both are very critical in the smooth operation of Simplicity bearings. A rolling element bearing may appear to initially operate in this condition, but it is operating in an extremely preloaded condition and will prematurely fail and in most cases destroy the shafting. Simplicity bearings will indicate the problem immediately upon installation by failing to move due to the binding condition. There are alternative mounting options that work extremely well.
Applies to standard linear bearing series. For sleeve and flange bearings, see product pages 38–39, 60–62, 70–71, and 78–80. Straight Bore Housing – Press Fit Bearing This type of configuration is NOT recommended for the vast majority of applications using Simplicity bearings. It does NOT allow for any misalignment or shaft deflection. Misalignment or shaft deflection will cause the bearing to bind on the shafting. Extremely high precision applications may be able to employ this type of mounting. Typically the shafting has been aligned with a laser or some other highly precise equipment. Due to bore closure in the pressing process, use a “C” series (compensated I.D.) bearing. Example: FLC24, FMC30, FJC30.
