Angular Contact Ball Bearing Introduction of bearing support:
Single row angular contact ball bearings can withstand a direction
of axial load, radial load, will cause additional axial force. And
the only limit in one direction of the axial displacement of shaft
or housing. Angular contact ball bearing contact angle of 40
degrees, it can withstand a lot of axial load. Angular contact ball
bearings are non-separable design, the shoulder on both sides of
the inner and outer rings uneven. In order to increase the load
bearing capacity, which would lower the shoulder side machined, so
that the ball bearings can be put more.
Features of bearing support:
High Quality Steel – Ultra clean steel to extend bearing life by up
to 80%.
Advanced Grease Technology – NSK lubricants that can extend grease
life and performance.
High Grade Balls – Quiet and smooth operation even at high speed.
Super Finished Raceways – Specially honed to minimise noise and
improve lubricant distribution and life.
Contact Angle – Offered in 15, 25, 30 and 40 degree angles.
Cages – Available in a range of Polyamide, steel and brass cage
assemblies.
Application of bearing support:
Machine tool spindles, high frequency motors, gas turbines,
centrifuges, small car front wheel, differential pinion shaft,
booster pumps, drilling rigs, food machinery, dividing heads, fill
welding, low-noise cooling tower, mechanical and electrical
equipment, coating equipment, machine slot board, arc welding
machine.
