Product Description

What this part is

SKF 7014 CD/P4ATT super-precision angular contact ball bearing set, supplied as a triplex tandem group of three. Bore: 70 mm. Outside diameter: 110 mm. Width: 20 mm per bearing. Contact angle: 15°. Precision class: P4A, equivalent to ABEC 7. Open on both faces. Weight: 1.41 lb per bearing.

Decoding the designation

7014: 70 series, 70 mm bore. CD: 15° contact angle, D-design execution. P4A: super-precision tolerance and running-accuracy class. TT: triplex tandem set, three bearings ground to run in one axial direction together.

What these specs mean in practice

Dynamic load rating: 39 kN (8,770 lbf) per bearing. Static load rating: 40 kN (9,000 lbf) per bearing. Limiting speed: 15,000 rpm. Maximum operating temperature: 120 °C. Three bearings in tandem share one thrust direction, so the group carries roughly three times the axial load a single bearing takes, at the same 15° angle. That is the configuration used where a spindle or screw drive pushes hard one way and needs a separate bearing to locate the other.

Quantity and configuration

Three bearings, ground as a triplex tandem set. Faces are matched, so the group clamps up as one stack.

Fitting notes

Shaft seat to h5 and housing bore to H6 or closer hold the P4A running accuracy. The three bearings are installed in the same axial orientation, with the marked faces aligned as ground.
