Rolling Elements: Ball. Contact Angle: 30°. Closure Type: Open. Cage Material: Pressed steel. Precision Class: Normal (ISO P0). Dynamic Load Rating: 26.9 kN. Static Load Rating: 21.1 kN. Limiting Speed: 6,700 rpm on grease, 9,500 rpm on oil. Item Weight: 0.263 kg.

Decoding the designation

7010 — NSK’s number for the ISO 7010 size, 50 x 80 x 16 mm, in the 70 light dimension series.

A — 30° contact angle.

W — pressed steel cage.

What these specs mean in practice

Contact Angle: 30°. NSK’s middle angle. It carries roughly twice the thrust of a 15° bearing on the same envelope and still runs fast enough for grease lubrication at 6,700 rpm. Thrust is carried in one direction only from a single row, so the shaft needs a second bearing or a shoulder facing the other way.

Dynamic Load Rating: 26.9 kN. Static Load Rating: 21.1 kN. The 70 light series keeps the outside diameter down to 80 mm on a 50 mm shaft, which is what makes it the usual choice where housing bore is the constraint.

Cage Material: Pressed steel. Low mass and low windage, which suits the grease-lubricated speed range.

Limiting Speed: 6,700 rpm on grease, 9,500 rpm on an oil bath.

Mounting data

Effective Load Centre (a): 26.8 mm from the bearing face. Shaft Abutment Diameter (da min): 56 mm. Housing Abutment Diameter (Da max): 74 mm. Maximum Abutment Fillet Radius (ra max): 1 mm. Bearing Chamfer (r min): 1 mm.

Quantity and configuration

Unit Quantity: 1 Pc. One open bearing, supplied as an individual bearing.

Interchange guidance

The 50 x 80 x 16 mm envelope is ISO standard and every maker’s 7010 shares it. The contact angle decides substitution. A 7010A or 7010AW is 30°. A 7010C is 15°, a 7010B is 40°, and a 7010E in the RHP and Fafnir schemes is 25°. All three fit the same seats but change the thrust-to-speed balance, so check the angle before substituting. The SKF-scheme 7010ACD is a machined-cage bearing on the same envelope with a different contact angle.

Searchable variants of the part number: 7010A, 7010 A, 7010AW, 7010A-W, 7010 AW.
