A Type-Thin section angular contact ball bearings

Apr 30, 2024
Compared with C-type bearing, A-type angular contact ball bearing has an enough radial clearance to form a sufficient contact angle to carry the axial load. The contact angle for the standard bearing is 30°.

A notable feature of A-type bearing ring is its assembling method. There is a slope at the rib of either of the bearing ring, usually of the outer ring. With the temperature differences on inner and outer ring, the inner and outer ring, balls and the cage can be assembled together to form a non-separable bearing. The bearing can carry the axial load, as well as a greater radical load. Under a certain axial load, the inner and outer rings of bearing can be preload for adjusting.

Compared with C-type bearing, more balls can be installed into A-type bearing, with this assembly method and a larger contact angle can be formed, to obtain a greater axial load carrying capacity.

Due to its bearing capacity in one direction, the bearing should be installed symmetrically in pairs with other bearing, to set and ensure the contact angle and the smallest axial movement under an alternating axial load.

CHG Bearing:Bearings for wind turbines
Apr 16, 2024
Blade bearings are used to connect blades with hubs in MW wind turbines, and they also can adjust the windward direction of blades to ensure electricity production with power rating and the safe work of wind turbines. Usually, single or double rows four-point contact ball slewing bearings are used as blade bearings, which have preload, special designed seals, anticorrosion surfaces,etc.
CHG Bearing:The lifespan of bearings
Mar 28, 2024
The bearing life refers to the number of revolutions or hours experienced by the bearing before the occurrence of pitting under a certain load. The life of rolling bearings is usually defined by the number of revolutions or the number of hours worked at a certain speed. During this lifespan, no initial fatigue damage (such as spalling or defects) should occur on any bearing ring or rolling element.
Assembly and disassembly of tapered roller bearings
Mar 21, 2024
Tapered roller bearings can be mounted directly on a tapered shaft or on a cylindrical shaft through an adapter sleeve or withdrawal sleeve. A tight fit is obtained by axially moving the inner ring. The tight fit of the inner ring can be effectively controlled by measuring the reduction in radial clearance caused by the expansion of the inner ring.
Four row tapered roller bearings
Mar 14, 2024
It usually consists of two double-row inner rings, a double-row outer ring and two single outer rings. There is an inner spacer ring between the two inner rings, and there are two middle spacer rings between the three outer rings. Such a design The bearing can adjust the clearance to adapt to different working conditions.
