SNR 7209CDUJ74 super-precision spindle angular contact ball bearing, ISO 72 series, 45 x 85 x 19 mm. Brand: SNR. Manufacturer Part Number: 7209CDUJ74. Bearing Type: Spindle angular contact ball bearing. Bore: 45 mm. Outside Diameter: 85 mm. Overall Width: 19 mm. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Ball. Closure Type: Open. Material: High carbon chrome steel.
Contact Angle: 15°, carried by the C in 7209C. Preload: Light, carried by the J74 code. Precision Class: ISO P4, equivalent to ABEC 7. Cage Material: Phenolic. Cage Type: Outer-land piloted. Series: 7200. Searchable forms of the designation: 7209CDUJ74, 7209-C-DU-J74, 7209 C DU J74, 7209C.
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 Clearance: N/A — the bearing is set by preload rather than by a running clearance. ISO P4 holds tighter bore, outside diameter and running accuracy than standard class. The outer-land piloted phenolic cage rides on the outer ring lands, which holds it concentric at speed. Lubricant: Oil.
Unit Quantity: 2 Pcs. Universally ground rings, matchable so the two bearings set together at the stated preload.
Cross-Reference 1: SKF 7209 CD/P4ADGA. Cross-Reference 2: FAG B7209-C-T-P4S-DUL. Fafnir carton equivalent: 2MM209WI CR DUL. A same-envelope bearing at a different contact angle is a related size rather than a substitution.
