Detailed Product Description

Angular Contact Ball Bearings) may also bear radial load and axial load. Be able to work at a high speed. Contact angle the greater the higher the axial load capacity. High-precision and high-speed bearings usually take 15-degree contact angle. In the role of the axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, in the radial load, will cause additional axial force. And can only be restricted shell axis or the axial displacement in one direction. If pairs of double-installed, so that a pair of bearing outer ring relative, that is, the face of wide-side wide face, narrow end of a narrow face to face. This can avoid additional axial force, but also in both directions so that shaft or housing to limit axial clearance range.
Angular contact ball bearing raceway for its inside and outside the circle on the horizontal axis can be a relative displacement, so it can also bear radial load and axial load - the joint load (single row angular contact ball bearings can only bear axial load in one direction, Therefore, often used in pairs are generally installed).
Cage materials are brass, synthetic resins, etc., depending on bearing form, the distinction between the conditions of use.
Angular contact ball bearings are: 7000C-type (α = 15 °), 7000AC-type (α = 25 °) and 7000B (α = 40 °) of several types. The kinds of bearings locking the outer ring on the inside and outside the ring can not be separated in general, can withstand radial and axial load as well as the co-axial load in one direction. Bear axial load capacity of the decision by the contact angle, contact angle greater then the ability to withstand high axial loads. The kinds of bearings can limit the axis or shell of the axial displacement in one direction.
Contact ball bearing a higher speed limit, you can at the same time to bear radial load and axial load, you can also bear a pure axial load, axial load capacity from contact angle of the decision, along with a contact angle increases.
Single row angular contact ball bearings can withstand axial load in one direction, in the radial load, it will cause additional axial force, we must reverse the appropriate facilities to load, therefore, the kinds of bearings are generally used in pairs. Double row angular contact ball bearings can withstand greater radial load mainly to the radial and axial load and bi-directional joint torque load, it can restrict shell axis or bi-directional axial displacement, the contact angle of 30 degrees.
Pairs of angular contact ball bearings can be installed in order to bear radial load mainly radial, axial two-way joint loads, you can also withstand a pure radial load. Tandem configuration can tolerate only a single direction axial load, the other two configurations can withstand axial load in either direction. This type of bearings are generally combination of pairs of matching manufacturers to submit a user, after installation preload of interference, ferrule and steel ball in the Pre-axial loading conditions, thereby enhancing the whole group as a single ring bearing stiffness and rotation accuracy.
Angular contact ball bearings of the main purposes:
Single row angular contact ball bearings: machine tool spindles, high-frequency motors, gas turbine, centrifugal separator, small car front wheel, the differential pinion shaft
