1.Double row angular contact ball bearing applications: compared with bearings double row angular contact ball bearing has better rigidity, can withstand the overturning. Bearings for separate. Especially suitable for high rigidity requirement of applications. Widely used in front of the car wheel (some models with size with double row circular cone roller bearings). 2.Double row angular contact ball bearing features: double row angular contact ball bearing between inner and outer QingXieXing can dynamically, allowing the bearing clearance, depends on the size and internal bearing in interior design and the bearing force and moment, while the maximum allowable gradient should guarantee the bearings won't produce high additional stress. If the bearings between the inner and outer dynamically, will affect bearing life, at the same time, running bearings, operation noise increases accuracy. Double row angular contact ball bearing commonly used nylon maintains or brass entity keep frame. Double row angular contact ball bearing should be paid attention to when installation, although the bearing can withstand two-way axial load, but if there are gaps, pack the ball should pay attention to don't let the main axial load through the gaps GouBian side. When used in bearing should pay attention to not take the ball roll gap installed side under main ways.
