Feature: Angular contact ball bearings can accommodate both radial and axial loads simultaneously, and axial loads in one direction, with limit rotational speeds higher. The greater the contact angular, the higher the axial load carrying capacity of the bearings. Applications: Applied in the machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, printing machines and other installations. We can produce different types of material and size of angular contact ball bearing per customers'' requirements. Specification: 1)Gcr 15 (AISI 52100/DIN 100Cr6/JIS SUJ2)chrome steel material 2)Tolerance standard: GB/T307(ISO492) 3)Hardness: HRC60-HRC65 4)ISO9001 certificate 5)single color box or tube or industrial paper packing We are the Original Manufacturer of the ball bearing, with no Middleman involved, so we can provide you Competitive Price and more Efficient Cooperation!!!
