RHP 7018CTDUHP4 Super Precision Angular Contact Ball Bearing, 90x140x24 mm, 15° Contact Angle, Heavy Preload, ABEC-7/P4

The RHP 7018CTDUHP4 is a super-precision single-row angular contact ball bearing measuring 90 mm bore x 140 mm OD x 24 mm width, built for machine-tool spindles and other high-speed, high-accuracy rotating applications.

Designation decode: 7018 (angular contact, 90 mm bore) · C (15° contact angle) · T (machined cage) · DUH (universally matchable/ground for duplex mounting, Heavy preload) · P4 (ISO Class 4 / ABEC-7 precision). The 15° contact angle favors high-speed running under combined radial and light axial load, and the DU universal grinding lets a pair be arranged back-to-back (DB), face-to-face (DF), or in tandem (DT) without shims.
