RHP 7017CTRDUMP3 Angular Contact Ball Bearing

The RHP 7017CTRDUMP3 YB212845A is a super precision single-row angular contact ball bearing engineered for high-speed spindles and precision rotating equipment. Designed for machine tool spindles, it delivers high radial and axial load capacity with a 15° contact angle and P3 precision class, housed in a phenolic resin cage with medium preload. Its bore is 85 mm, outside diameter 130 mm, and total width 44 mm (matched pair designation), making it suitable for CNC machine tools, grinding machines, machining centers, and other high-speed precision applications requiring rigidity and long service life. Operating up to 120°C, this bearing supports machine tool spindle applications and is commonly used for spindle support, with common replacements including NSK 7017CTRDUMP3, SKF 7017 CD/P4A, and FAG B7017-C-T-P4S.
