Radial angular contact bearings in pairs Why bearing, install backward? Single-sided angular contact bearings can withstand axial force engraving machine spindle bearings / 7005 / P5, it is usually with a combination of installation. Generally there are three kinds of combinations: a combination of positive and negative combinations, the series combination, choose according to the actual situation. Advantage is that it can withstand the negative combination radial load and axial load, especially for a single moment to bear angular contact bearings can withstand axial force on one side, it is generally with a combination of installation. Generally there are three kinds of combinations: a combination of positive and negative combinations, the series combination, choose according to the actual situation. Advantage is that it can withstand the negative combination radial load and axial load, especially for ways to edit a maintenance support moments, when the bearing is run to a certain period (or security maintenance support period) engraving machine spindle bearing 7002 / P5, bearing All removed; 2, with clean diesel or kerosene soaked with cleaning bearings, if the conditions are best sealed cover clean technology; 3, air dry after cleaning cleaning oil, a visual inspection for damage; 4, with about a 150mm, angular contact ball bearing diameter equal to the inner diameter of the stick (preferably hollow tube), one end is fixed a bearing; 5, rapid rotation of the bearing by hand while the stick (woodwind) the other end of the top of the ear microphone or audio amplifier listen to the debate bearing rotation noise; Greeting engraving machine spindle bearing, along GF bearing Electrical (certified), the bearing is provided by Shenzhen-GF bearing Electrical Co., Ltd..
