Single row angular contact ball bearing: It is the solution for where a joint load of radial and axial direction exists, and at the same time it can offer high rotating speed.
We provides bearings for ID from 10mm to 230mm with angles of
15,25,40,60.
Double-row angular contact ball bearing:
1.When contact angle α=45, bearing type is 3300D;
2.When contact angle α=30,bearing type is 3300.
Angular contact ball bearings are mainly used for mining machinery, metallurgy machinery, CNC lathes, CNC grinding machines and multi-spindle machines.
Description:
Angular contact ball bearings can bear radial load and axial load
at the same time, also can withstand pure axial load which is
determined by the contact Angle. It can work under high speed.
Under the effect of axial force, the contact Angle increases, the
greater the contact Angle, the higher the axial load.
Applications:
Angular contact ball bearings are used for machine tool spindles,
high frequency motors, gas turbines, centrifuges, small car front
wheel, differential pinion shaft, booster pumps, drilling
platforms, food machinery, dividing head, welding machine, low
noise cooling towers, electrical and mechanical equipment, painting
equipment, machine slot board, arc welding machine.
Competitive advantages:
Our company product and export bearings for 20years, so we have a
deep knowledge of bearing. We can guarantee the quality and the
price, and we ensure our production can meet your requirement. In
addition, we can manufacture the production according your
requirement.
