The HFH B7013-E-T-P4S-UL is a high precision angular contact ball bearing, specifically engineered for demanding machine tool spindle applications. This bearing features a 65mm bore diameter, 100mm outer diameter, and 18mm width, designed to accommodate high rotational speeds and provide superior rigidity. The 'E' designation indicates a 25° contact angle, optimized for handling significant axial and radial loads. It incorporates a durable phenolic resin cage ('T') to minimize friction and heat generation during high-speed operation. With a P4S precision class, this bearing delivers exceptional running accuracy and performance, while the 'UL' suffix denotes universal matching with a light preload, ensuring optimal performance when used in sets.
