The angle is exposed to the electric main shaft introduction of the ball bearing


29th June 2013 Bearing Technology 0 Comments
1. The ball bearing? The main axle construction of electricity generally adopts the angle to contact the ball bearing to support, the disposition form of the bearing depends on loaded magnitude, direction, the rotational speed of the basic shaft and job requirements of the basic shaft. The electric basic shaft that the angle is exposed to the ball bearing generally adopts the support way pursuing to be shown. Horn exposed to ball bearing in add the normal operation of ability under loaded terms in advance axially. Adding the load in advance not only can dispel the axial backlash of the ...

Grinding processing and high-speed grinding technology of the bearing ring


29th June 2013 Bearing Technology 0 Comments
In bearing production, process the amount of labour and account for 60% of the total amount of labour in grinding, the used grinding machine quantity accounts for about 60% of all metal cutting lathes too, the cost processed in grinding accounts for more than 15% of the cost of whole bearing. As to the high-accuracy bearing, these proportions processed in grinding are larger. In addition, it is most complicated in the whole processing course that grinding is processed, it is still the most insufficient link so far to its understanding. This complexity shows: Require more performance indexes, ...

Roller bearing of thrust of Henan


29th June 2013 Bearing Technology 0 Comments
Thrust roller bearing is used for bearing the axial load and uniting the load for the axle, radial of the main fact, but the radial load can't exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing is lower in friction factor, the great of rotational speed, and have cente adjusting characteristics. The rod of the 29000 type bearing is a asymmetric sphere roller, can reduce the roller and relative slip at work of ball track, and the long, diameter of roller is large, rollers are in large quantity, the load is tall in capacity, usually adopt the oil ...
