SKF7002CDP4ASuper-Precision Angular Contact Ball Bearing 15 x 32 x 9 mm, 15° Contact Angle, Open

Product Description

What this part is

This is an SKF 7002 CD/P4A super-precision angular contact ball bearing with a 15 mm bore, 32 mm outside diameter and 9 mm width. It is an open bearing with no seal or shield on either face, built for machine tool spindles and other high-speed, high-accuracy rotating assemblies.

Decoding the designation

The 7002 base number places the bearing in the ISO 72 light dimension series with a 15 mm bore. The CD suffix specifies a 15° contact angle. The P4A suffix is SKF’s super-precision tolerance and running-accuracy class, and it also denotes a universally matchable single bearing, so any two pieces of the same designation can be arranged back-to-back, face-to-face or in tandem without a spacer or a factory-matched pair.

What these specs mean in practice

A 15° contact angle sits at the high-speed end of the angular contact range. It carries less axial thrust than a 25° bearing of the same envelope but runs faster and generates less heat, which is why 15° is the usual choice for the front position on a grinding or milling spindle. Radial load capacity is comparable between the two angles; the difference is almost entirely in thrust capability and speed.

Quantity and configuration

Single bearing, 1 Pc. Universally matchable, so it can be used alone or built into a duplex or triplex stack with further pieces of the same designation.

Fitting notes

Super-precision bearings of this class expect a ground and dimensionally controlled shaft and housing seat, and preload is set by the arrangement and by axial clamping rather than by the bearing itself. Handling is done clean, and the bearing is mounted without heating or impact, with force applied through the ring being fitted.

Interchange guidance

The direct same-spec equivalents in other schemes are FAG B7002-C-T-P4S, NSK 7002CTRP4 and RHP 7002CTP4 — all 15°, 15 x 32 x 9 mm super-precision singles. A 7002 ACD/P4A shares the same envelope but carries a 25° contact angle, which makes it a related size rather than a substitution.
