Product Description

What this part is

SKF 7017 C/P4 DGA super-precision angular contact ball bearing. Series: 70, extra-light section. Base number: 7017. Bore: 85 mm. Outside diameter: 130 mm. Width: 22 mm. Single row, straight bore, open on both faces. Searchable variants of the designation: 7017C/P4DGA, 7017 C P4 DGA, 7017CP4DGA, 7017-C-P4-DGA, 7017C.

Decoding the designation

Contact Angle: 15°. Precision Class: P4, equivalent to ABEC 7. Preload: extra light. Cage: machined phenolic, outer-ring-land-riding.

What these specs mean in practice

A 15° contact angle favours speed and radial rigidity over thrust capacity, which is why this execution is standard in machine tool spindles and precision grinders. Extra light preload holds running accuracy with low heat generation. Basic dynamic load rating: 67.6 kN. Basic static load rating: 65.5 kN.

Quantity and configuration

Two bearings. Unit Quantity: 2 Pcs. Universally matchable execution, ground to the extra light preload class. Internal Clearance: N/A — the bearings are preload-set, not clearance-set.

Fitting notes

Mounting is by interference on the inner ring seat with the outer ring located axially in the housing. Oil or grease lubrication both suit the phenolic cage.

Cross-references

FAG B7017-C-T-P4S-DUL and Fafnir 2MM9117WI CR DUL are 15° duplex pairs of this size at light rather than extra light preload. SKF 7017 ACD/P4A carries a 25° contact angle and a different thrust capacity.
