RHP7010CTBSULP6Angular Contact Ball Bearing – 50 mm Bore x 80 mm OD x 16 mm Wide, 15° Contact Angle, Machined Phenolic Cage, Light Preload, ABEC 3

Product Description

What this part is:

RHP 7010CTBSULP6 single-row angular contact ball bearing, ISO 7010 size. Bore: 50 mm. Outside Diameter: 80 mm. Width: 16 mm. Bearing Type: Single-row angular contact ball bearing. Number of Rows: 1. Rolling Elements: Ball. Contact Angle: 15°. Closure Type: Open. Cage Material: Phenolic. Cage Type: One-piece machined, inner-ring centred. Precision Class: P6, equivalent to ABEC 3. Preload: Light. Dynamic Load Rating: 26 kN. Static Load Rating: 21.9 kN. Item Weight: 0.259 kg.

Decoding the designation:

7010 — the ISO 7010 size, 50 x 80 x 16 mm, in the 70 light dimension series.

C — 15° contact angle.

TB — one-piece machined phenolic cage, centred on the inner ring.

SU — universal face control: the faces are ground so two or more bearings stack in any orientation and reach the specified preload without shims.

L — light preload class.

P6 — ISO tolerance class 6, equivalent to ABEC 3.

What these specs mean in practice:

Contact Angle: 15°. The shallowest of the standard spindle angles, chosen where speed and radial stiffness matter more than thrust capacity.

Cage Material: Phenolic. Cage Type: One-piece machined, inner-ring centred. Fabric-reinforced phenolic runs light and quiet at speed, and inner-ring centring locates the cage on the faster race.

Preload: Light. Universal face control means any two bearings of this designation, mounted back-to-back, face-to-face or in tandem, come up to the light preload figure on assembly. A single bearing also runs on its own against a shoulder.

Dynamic Load Rating: 26 kN. Static Load Rating: 21.9 kN. The 70 light series keeps the outside diameter at 80 mm on a 50 mm shaft, giving a thin section for a spindle nose.

Precision Class: P6 (ABEC 3). Bore, outside diameter and running accuracy are held tighter than a standard-class bearing.

Mounting data:

Effective Load Centre (a): 16.7 mm at 15°. Shaft Abutment Diameter (d1 min): 56 mm. Housing Abutment Diameter (D1 max): 74 mm. Outer Ring Face Abutment (D2 max): 75 mm. Bearing Chamfer (r min): 1 mm. Inner Chamfer (r1 min): 0.6 mm. Internal Free Volume: 12 cm³.

Quantity and configuration:

Unit Quantity: 1 Pc. One universally ground bearing, which mounts singly or stacks with others of the same designation into a duplex, triplex or quad set.

Interchange guidance:

The 50 x 80 x 16 mm envelope is ISO standard. The RHP B-series equivalent is B7010X2TULEP3, where X2 is the same 15° angle and EP3 the same ABEC 3 class. In the NSK scheme the equivalent is 7010C; in the Fafnir scheme, 2MM9110WI, where 2MM also denotes 15°. Contact angle governs substitution: a 7010A5 or 7010E is 25° on the same seats and a 7010A is 30°, both of which change the thrust-to-speed balance and are related sizes rather than direct swaps.
