B 7017- e -2 rsd-t-p4s-ul

The B7017-E-2RSD-T-P4S-UL is a single-row super precision angular contact ball bearing designed for applications demanding the highest℃of rotational accuracy and speed. The "P4S" designation signifies superior dimensional and running tolerances, ensuring exceptional precision in machine tool spindles and other high-stakes equipment. This bearing features an optimized internal design ("E") and a 25-degree contact angle, which allows it to accommodate high radial and axial loads in one direction. The inclusion of non-contact, low-friction lip seals on both sides ("2RSD") provides excellent protection against contaminants and helps retain lubricant, a crucial feature for Att upprätthålla prestanda och förlänga livslängden i utmanande driftsmiljöer .

A key advantage of the B7017-E-2RSD-T-P4S-UL lies in its advanced material composition and construction. It is fitted with a "T"-suffix textile laminated phenolic resin cage, guided by the outer ring, which is lightweight, strong, and permits very high rotational speeds while minimizing friction and heat generation. The "UL" designation indicates a universal design with a light preload, allowing these bearings to be installed in pairs or sets for various arrangements without compromising performance. This combination of extreme precision, high-speed capability, integrated sealing, and versatile mounting makes it an indispensable component for CNC machining centers, high-speed grinding spindles, and other applikationer där noggrannhet är av största vikt .
