SKF 7015 ACD/P4A TBTB super-precision angular contact ball bearing set. Series: 70. Base number: 7015. Bore: 75 mm. Outside diameter: 115 mm. Width: 20 mm per bearing, 60 mm across the set. Single row per bearing, straight bore, open on both faces. Searchable variants of the designation: 7015ACD/P4ATBTB, 7015 ACD P4A TBTB, 7015ACDP4ATBTB, 7015-ACD-P4A-TBTB.
Contact Angle: 25°. Design: ACD high-capacity super-precision execution. Precision Class: P4A, equivalent to ABEC 7. Set code TBTB: T = three bearings, arranged tandem against back-to-back, light preload. Cage: machined, fabric-reinforced phenolic.
A 25° contact angle carries more thrust and less speed than a 15°. The tandem pair shares one direction of thrust between two bearings, and the third bearing opposes it, so the set takes a heavy load in the tandem direction and locates the shaft in both. Light preload balances stiffness and axial location accuracy against heat generation. Basic dynamic load rating: 108 kN. Basic static load rating: 140 kN. Limiting speed: 9500 rpm.
Three bearings. Unit Quantity: 3 Pcs. Mounting arrangement: tandem against back-to-back. Internal Clearance: N/A — the set is preload-set, not clearance-set.
Ring faces are ground so that clamping the stack solid produces the specified light preload. The two tandem bearings face the same way and the third opposes them, so stack orientation is fixed by the ground faces. Operating range: -30 °C to 100 °C.
FAG B7015-E-T-P4S and Fafnir 3MM9115WI match the 25° bearing but are sold as singles, not a TBTB set. SKF 7015 CD/P4A is the same size at 15°.
