Use of bearings

For long-term storage, it is advisable to store on a shelf 3cm above the ground under the condition that the humidity is lower than 65% and the temperature is about 20 °C. In addition, the storage place should be protected from direct sunlight or contact with cold walls

Mounting of bearings

1. Preparation of bearings

Since the bearings are treated and packed with rust protection, do not open the packaging until it is installed. In addition, the anti-rust oil coated on the bearing has good lubrication performance, and it can be used directly without cleaning for general-purpose bearings or bearings filled with grease.

However, for bearings for instrumentation or bearings for high-speed rotation, clean cleaning oil should be used to wash off the anti-rust oil, at which time the bearing is easy to rust and cannot be put for a long timePlace.

2. Inspection of shaft and shell

Clean the shaft and housing to make sure there are no scars or burrs from machining. There must be no abrasive (SiC, Al2O3, etc.) molding sand, cutting, etc. in the shell. Secondly, check whether the size, shape and processing quality of the shaft and shell are consistent with the drawings.

As shown in Fig. 1 and Fig. 2, the shaft diameter and housing aperture are measured in several places. Also carefully check the rounded dimensions of the shaft and the housing and the perpendicularity of the shoulders. Before installation, apply mechanical oil to each mating surface of the shaft and shell that pass the inspection.
