SKFAngular Contact Ball Bearing, 70x125x24 mm, 15° Contact Angle, Phenolic Cage, Open

Product Description

What this part is

A single angular contact ball bearing in the ISO 7214 envelope: 70 mm bore, 125 mm outside diameter, 24 mm width.

The product photograph shows a brown phenolic cage, which is the lighter, self-lubricating cage type specified for higher-speed spindle work in preference to a pressed-steel cage, and the outer ring is stamped MADE IN USA – SKF’s American precision plant, the former MRC operation.

Decoding the designation

The C in the designation is a 15 degree contact angle, which biases the bearing toward speed and radial capacity rather than maximum thrust – the 25 and 40 degree alternatives in the same envelope trade speed away for axial load.

What these specs mean in practice

Angular contact bearings develop an axial force component under radial load, so a single bearing locates a shaft in one direction only; where thrust reverses or rigidity matters, two are mounted back-to-back (DB), face-to-face (DF) or in tandem (DT).

Typical duty is machine-tool spindles, pump and compressor shafts, gearboxes and vertical assemblies carrying combined radial and axial load.

Quantity and configuration

One bearing is supplied, sealed in the original SKF bag.
