ZKLF2575-2RS Angular Contact ball screw support bearing
Product Description of Angular Contact ball screw support bearing
structure as a separate outer ring, two and a half of inner ring and ball cage components and sealing ring. , is made up of two direction of 60 ° arranged according to O form of angular contact ball bearing contact Angle. •
can withstand the bearing load from two directions can bear radial load. , can be in assembly time is obtained by precise locknut preloading. , a sealing ring or dust cover to prevent the pollution of bearing internal. , bearing is pre-filled with the high quality and long life of compound lithium base grease.
Can then be reproduced by greasing holes, grease lubrication.
can work at 30 ° C to + 120 ° C - (by grease, sealing ring material and plastic cage's decision). , can be used for precise installation of occasions, such as driving screw. • double sealing ring or dust cover.

Features of angular contact ball bearing
An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race.
Ceramics such as silicon nitride are now regularly used in such
applications due to their low density (40% of steel). These
materials significantly reduce centrifugal force and function well
in high temperature environments. They also tend to wear in a
similar way to bearing steel-rather than cracking or shattering
like glass or porcelain.
