Decoding the designation

7015 — SKF’s number for the ISO 70 dimension series at a 75 mm bore, giving a 75 x 115 x 20 mm envelope.

C — 15° contact angle.

P5 — ISO tolerance class 5, equivalent to ABEC 5.

TC — machined cage in fabric-base laminate phenolic, guided on the outer ring land.

What these specs mean in practice

A 15° contact angle biases the bearing toward speed and radial stiffness. It carries less thrust than a 25° execution and runs faster and cooler in a spindle.

A phenolic cage guided on the outer ring land is light, self-lubricating and dimensionally stable at speed, which is why it is the standard choice in machine-tool spindle positions.

ISO P5 holds bore, outside diameter and running accuracy to tighter limits than normal class, so shaft location and running runout are closer.

Open on both faces, so the bearing takes its lubricant from the spindle system — grease or oil.

Quantity and configuration

Unit Quantity: 1 Pc. Single bearing, straight bore, open both faces.

Interchange guidance

Carton cross-references: Fafnir 2MM9115WI CR and FAG B7015-C-T-P5-UL. Both share the 75 x 115 x 20 mm envelope at 15° with a phenolic cage in ISO class 5.
