Angular-contact bearing

single-rowsteelstainless steel

Angular contact bearings have similar construction to deep groove bearings except for the specific track geometry to withstand combined radial and axial loads. General Features In the single-row version they must always be coupled with another opposing bearing, usually the same, but for specific cases also with different size and contact angle. As the contact angle increases, the axial load bearing capacity also increases. They can be made in many variations: Shielded with grease (for life); Open without grease; Lubricated directly in the machine with oil or grease. In addition, they can be produced with various types of cages: brass, steel, plastic depending on the requirements of use. When preloaded, they have the advantage of offering high stiffness. They can withstand very high rotational speeds depending on the contact angle. Depending on technical requirements, they can have special coatings, e.g., chrome, phosphating, galvanizing, or black oxide. Materials In most cases they are made of typical chromium bearing steel, either full hardening or case hardening. For special application requirements they can be made of stainless steel. In special cases ceramic balls can be adopted. Main Applications Textile looms, Planetary gearboxes, machine tools, axles, bottling machines.
