NSK 7017CTRSULP4Y is a single-row super-precision angular contact ball bearing from the 70 series. Bore Diameter: 85 mm. Outside Diameter: 130 mm. Overall Width: 22 mm. Contact Angle: 15°. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Number Of Rows: Single Row. Bearing Material: Bearing Steel. Series: 70 Series. Base Number: 7017C.
Dynamic Load Rating: 76,000 N per bearing. Static Load Rating: 58,500 N per bearing. Limiting Speed: 10,700 rpm grease; 16,300 rpm oil. Item Weight: 0.898 kg (1.98 lb) per bearing. Load ratings and mass are quoted per bearing.
7017 — 70 series super-precision angular contact ball bearing on an 85 mm bore.
C — 15° contact angle.
TR — phenolic resin cage, outer-ring guided.
SU — single bearing, universally ground, so like bearings pair in any arrangement.
L — light preload class.
P4Y — NSK precision grade equating to ABEC 7 / P4.
The 15° contact angle biases capacity toward radial load and raises the speed ceiling relative to steeper 25° and 30° angles, which is why the C angle dominates machine-tool spindle work. Precision Class: ABEC 7 / P4. Preload: Light (L). Cage Material: Phenolic. Cage Type: Outer-ring guided. Lubricant: Grease or oil / oil-air.
A phenolic cage guided on the outer-ring land runs quiet and tolerates the high cage-pocket sliding speeds of a spindle bearing, and its low mass keeps unbalance forces down at the top of the speed range. Light preload trades axial rigidity for reduced heat generation, favouring the higher end of the speed band.
Effective load centre a: 25.4 mm. Permissible axial load Pa: 38.0 kN. Minimum shaft abutment diameter da: 92 mm. Maximum housing abutment diameter Da: 123 mm. Maximum housing abutment diameter Db: 125 mm. Maximum shaft fillet radius ra: 1 mm. Maximum housing fillet radius rb: 0.6 mm. Minimum chamfer dimension r: 1.1 mm. Minimum chamfer dimension r1: 0.6 mm. Recommended grease quantity: 4.9 g per bearing. Calculation factor f0: 15.9.
Unit Quantity: 1 Pc. Mounting Arrangement: Single, universally ground (SU).
Dimensionally and functionally comparable 85x130x22 mm super-precision 15° angular contact bearings are catalogued by other makers as SKF 7017 CD/P4A, FAG B7017-C-T-P4S, Timken/Fafnir 2MM9117WI, RHP 7017CTDU, Koyo 7017C, NTN 7017CG/GNP4 and GMN S 6017 C. Preload class, cage and accuracy grade must be matched code for code before any of these is treated as a drop-in.
