Decoding the designation

Contact Angle: 25°. Preload: medium. Precision Class: ABEC 7, equivalent to P4. Cage Material: phenolic. Cage Type: machined, outer-ring land-riding. Mounting Arrangement: universally ground. Lubricant: oil or grease. Minimum Temperature: -30°C. Maximum Temperature: 120°C.

The carton carries this bearing in four schemes: SNR 7015 H DU J84, FAG 7015-E-T-DUM-P4, Fafnir 3MM9115WI CR DUM and SKF 7015 ACD/P4ADGB. Searchable variants of the number include 7015HDUJ84, 7015 H DU J84 and 7015-H-DU-J84.

What these specs mean in practice

A 25° contact angle steepens the load path through the ball, raising thrust capacity and axial stiffness against a 15° execution on the same envelope. It suits a spindle position carrying genuine axial load alongside its radial load.

Medium preload sits a step above light. It buys more axial and radial stiffness and tighter shaft location, at the cost of a lower speed ceiling and more heat generated in the contact. That is the setting chosen where cut quality and positional repeatability matter more than top spindle speed.

The machined phenolic cage is light and absorbs oil, so it runs cooler and quieter than brass or steel at high shaft speed, and the 120°C ceiling reflects the phenolic. Riding on the outer-ring land centres the cage on the stationary ring, steadying cage motion through acceleration and deceleration. ABEC 7 precision holds low radial and axial runout and gives close, repeatable shaft location.

Quantity and configuration

Unit Quantity: 2 Pcs. This listing supplies a matched duplex pair, universally ground so the two bearings can be clamped together in any face orientation and will arrive at the designed medium preload.

Interchange guidance

Cross-Reference: FAG 7015-E-T-DUM-P4. Cross-Reference: Fafnir 3MM9115WI-DUM. Cross-Reference: SKF 7015 ACD/P4ADGC (SKF medium preload is DGC; DGB is light). Harmonization Code: 8482.10.50.68. A same-envelope 7015 built at 15° is a related size rather than a substitution, because the shallower angle changes both the thrust capacity and the speed behaviour. A light-preload execution of the same number is likewise a related build, not a substitution.
