Stainless Steel Thin-Section Ball Bearing Series – Type A
Most Commonly Used Materials and Selection in Commercial Application References of QIBR Stainless Steel Thin-Walled Ball Bearing Series-Open Type A
The QIBR stainless steel thin-walled ball bearing series -open type A is commonly used in commercial applications where space is limited. These bearings are lightweight and compact, capable of withstanding significant axial loads. The axial load capacity of the open type A bearings depends on the contact angle; a larger contact angle enhances axial load capacity. Unlike type C bearings, type A bearings have sufficient radial clearance to form an adequate contact angle for axial load support. They possess unidirectional load capacity and require symmetrical pairing with other bearings for installation. The series offers a variety of size specifications to meet different installation requirements, making them suitable for space-constrained applications.
The open type A bearings are typically made from stainless steel grades such as 440, 420, 304, and 316, providing excellent corrosion resistance, wear resistance, strength, stiffness, and high-temperature tolerance, which extends the bearing's lifespan in harsh environments.
