Product Description

What this part is:

SNR 7017CDUJ74 super-precision angular contact ball bearing, ISO 70 series, 85 x 130 x 22 mm. Brand: SNR. Manufacturer Part Number: 7017CDUJ74. Bearing Type: Angular contact ball bearing. Bore: 85 mm. Outside Diameter: 130 mm. Overall Width: 22 mm. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Ball. Closure Type: Open.

Decoding the designation:

Contact Angle: 15°, carried by the C in 7017C. Preload: Light, carried by the J74 code. Precision Class: ISO P4, equivalent to ABEC 7. Cage Material: Phenolic resin. Series: 7000. Searchable forms of the designation: 7017CDUJ74, 7017-C-DU-J74, 7017 C DU J74, 7017C.

What these specs mean in practice:

A 15° contact angle favours speed and radial rigidity over thrust capacity, which suits a machine-tool spindle position. Light preload keeps the ball complement in contact under a modest set force, giving repeatable running accuracy with low heat generation. Internal setting is by preload rather than by a running clearance. ISO P4 holds tighter bore, outside diameter and running accuracy than standard class, locating the shaft more closely and running with less vibration. The phenolic cage is light and quiet at speed.

Quantity and configuration:

Unit Quantity: 1 Pc. One bearing from a factory matched pair, universally ground so it sets against a like bearing at the stated preload.

Interchange guidance:

Cross-Reference 1: SKF 7017 CD/P4A. Cross-Reference 2: NSK 7017CTYNSULP4. Cross-Reference 3: FAG B7017-C-T-P4S. Fafnir carton equivalent: 2MM9117WI CR SUL. A 7017 built at a different contact angle is a related size rather than a substitution.
