Cleaning and inspection of bearing housings

Before the bearing seat is installed, it should also be thoroughly cleaned and inspected. Scrape off the dirt in the inner cavity of the bearing housing with a scraper, wipe the dirt with a cloth dipped in gasoline or solvent, and check for cracks and blisters to prevent oil leakage during operation. The joint surface of the bearing cover and the bearing seat, the joint surface of the bearing seat and the bearing oil retaining ring should be ground and scraped, and checked with a feeler gauge, and the gap should not be greater than 0.03 mm. The surface of the bottom plate on which the bearing seat is placed should also be cleaned, and there should be no bumps, rust and burrs. The screws that fasten the bearing seat and the thread of the seat plate should be carefully checked by him, and try to tighten the screws to check whether they are too tight or bald.
