NSK 7020CTRSULP4Y single-row super-precision angular contact ball bearing. Series: 70, light section. Bore: 100 mm. Outside Diameter: 150 mm. Width: 24 mm. Open on both faces, machined outer-ring-guided phenolic cage, steel balls on steel raceways. Searchable forms of the designation: 7020CTRSULP4Y, 7020 CTR SUL P4Y, 7020C TRSULP4Y, 7020C-TR-SUL-P4Y, 7020CTRSUL P4Y.
Contact Angle: 15°. Cage: TR — outer-ring-guided phenolic, rated for continuous service to 120°C. Matching: SUL — a single bearing, universally ground, light preload. Precision Class: P4Y, a special NSK class held tighter than P4.
A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why it is the standard choice for high-speed grinding and milling spindles. An outer-ring-guided phenolic cage runs quieter and cooler than a ball-guided cage at high speed, because the cage is piloted on a lubricated land rather than on the balls, and phenolic is light enough to keep cage inertia low. Dynamic Load Rating: 74.0 kN. Static Load Rating: 80.0 kN. Limiting speed: 13 600 r/min. P4Y raises running accuracy above standard ABEC 7, giving lower radial and axial runout at the spindle nose.
One bearing. Unit Quantity: 1 Pc. Universally ground as a single, so it reaches the specified light preload when clamped against another bearing of the same designation. Open bearing, lubricated on installation with oil or grease.
The phenolic cage sets the temperature ceiling at 120°C. Preloaded bearings run without internal clearance, so shaft and housing seats are held to super-precision tolerances.
Same-specification single bearings: SKF 7020 CDGA/P4A and FAG B7020-C-T-P4S-UL. The duplex-pair designations FAG B7020-C-T-P4S-DUL, Fafnir 2MM9120WI-DUL and SKF 7020 CD/P4ADGA cover the same envelope and contact angle as matched pairs. RHP 7020A5T shares the envelope.
