Both sides with a dust cover type and sides with a ring type, A-type design and E-type design of double row angular contact ball bearings are on both sides with a dust cover (non-contact) or seals (contact). Sealed bearings are filled with anti-rust lithium grease, generally between -30 degrees to 110 degrees operating temperature. Without re-lubrication during use, no heating before installation. Double row angular contact ball bearing installation should pay attention to, although bearings can withstand axial load, but if one side when the ball gap Shenzhen high-speed precision bearings, you should be careful not to let the main axial load through the side of the gap Mizobe. Bearing installation should be preceded by gasoline or kerosene to clean Shenzhen engraving machine bearing wholesale dry before use, and to ensure good lubrication, bearings are generally lubricated with grease Shenzhen High-precision bearings 7005p4, oil lubrication can be. When using grease lubrication should be used without impurities, oxidation, rust, extreme pressure grease with superior performance. Grease filling amount of bearings and bearing housing volume of 30% -60% support, not too much. Bearings and pump shaft seal structure has been populated even bearing grease, users can directly use, can no longer be cleaned.
