RHP 7017CTSULP6 single-row super-precision angular contact ball bearing. Bore 85 mm, outside diameter 130 mm, width 22 mm. ISO 70 series, size 7017, straight bore, open both faces. RHP is a British maker, now part of NSK. Made in England, new old stock.
Contact Angle: 15°, from the RHP C code. Cage Type: machined, outer-ring guided. Cage Material: laminated phenolic, from T, rated to 120 °C. Grouping: SUL, single universally ground to light preload. Precision Class: P6, equivalent to RHP EP3 and ABEC 3. Series: ISO 70. Base Number: 7017.
Dynamic Load Rating Cr: 76.0 kN. Static Load Rating C0r: 58.5 kN. Limiting speed: 10,700 rpm on grease, 16,300 rpm on oil-air lubrication. Effective load centre a: 25.4 mm. Mass: 0.898 kg.
A 15° contact angle favours speed and radial load over thrust, which is why it is the standard choice for the front position of a high-speed spindle. A machined phenolic cage riding on the outer ring land runs light, damps well and holds up to 120 °C. Light preload removes play without adding much heat. P6 tolerances sit a step below P4 on runout, which suits general precision machine work rather than fine grinding.
One bearing, universally ground to light preload. Universal grinding lets it pair with any other bearing of the same designation back-to-back, face-to-face or in tandem, arriving at the ground preload with no spacer grinding.
Shaft abutment diameter da: 92 mm minimum. Housing abutment diameter Da: 123 mm maximum. Housing fillet radius ra: 1 mm maximum. Chamfer r: 1.1 mm minimum, r1: 0.6 mm minimum.
The carton carries three schemes for the same bearing: RHP 7017-C-T-SUL-P6, RHP B-series B7017X2TAULEP3, and the Fafnir cross 2MM9117WICRSUL. All three read 15° and the P6 / EP3 / ABEC 3 class. SKF 7017 CD/P4A and NSK 7017CTYNSULP4 share the envelope and the 15° angle at a tighter class, so they are related sizes.
