Open Deep Groove Ball Bearings
27/05/2013 16:01Open deep groove ball bearings for high speed or high speed operation, and is very durable, without regular maintenance. This kind of bearing friction, high limiting speed, size range and diverse, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used of a class of bearings. Main radial load, but also can withstand a certain amount of axial load.
With a ring of deep groove ball bearings
Standard with a ring of deep groove ball bearings with contact seals bearing RS-type (side seal), 2RS type (unsealed) and non-contact sealed bearings RZ-type (side seals), 2RZ type (sealed on both sides). With a ring of bearing performance, Tim grease and Usage bearings with dust cover basically the same. The difference is that with a dust cover dust cover bearing a greater gap between the inner ring, instead contact seals bearing the seal lip with a small gap between the inner ring, contact seals and bearing the seal lip there is no gap between the inner sealing effect is good, but the friction increased.
There are low-noise requirements of the occasion, the use of 60 and 62 series of smaller sized deep groove ball bearings. Whether open bearings with dust cover type or with a ring-type bearing, can be raised in order low noise, low vibration requirements. In China JB (Machinery Industry Standard) as specified in the V1, V2, V3 each vibration levels low, medium and high three-band vibration allowable value.
