Tips For Bearing Installation

Proper installation enables bearings to perform better and extend their lifespan. Here are some practical installation tips.

Clean the Installation Environment
When installing bearings, choose a dry and dust - free area, away from equipment that generates metal debris and dust. If installation in a complex environment is necessary, minimize contamination. As impurities in the bearings will accelerate wear and affect normal operation.

Select the Right Installation Method
For small bearings with a less tight fit, use a sleeve and gently tap the sleeve with a hammer to install the bearing in place. Tap evenly to avoid tilting the bearing. Most bearings are installed by the press - in method. When installing both the inner and outer rings onto the shaft and in the bearing housing simultaneously, ensure the same pressure acts on both rings and the installation tool's contact surface is on the same plane. For larger bearings, thermal installation is common. The larger the size, the greater the installation force required. During thermal installation, the temperature difference between the bearing ring and the shaft or bearing housing depends on the interference amount and the diameter of the bearing's mating part. Note that the heating temperature of open - type bearings should not exceed 120°C, and for bearings with seals and dust covers, it should not exceed 80°C. Also, heat evenly to avoid local overheating.

Installation Points for Tapered Bearings
For bearings with tapered bores, the inner rings are mostly installed with an interference fit. For small - and medium - sized bearings, use a bearing installation tool or a locking nut to push the inner ring onto the tapered shaft diameter at the appropriate position. If using a adapter sleeve, use a sleeve nut that can be locked with a hook - spanner or impact wrench. For a withdrawal sleeve, use a bearing installation tool or end plate to push it into the bearing inner hole. Larger bearings require more force for installation, and a hydraulic nut should be used at this time.
