RHP7016CTBSULP6Angular Contact Ball Bearing – 80 mm ID, 125 mm OD, 22 mm Width, Open, 15° Contact Angle, Light Preload, Phenolic Cage, P6 / ABEC 3

Product Description

What this part is

RHP 7016CTBSULP6 angular contact ball bearing, single row. Bore: 80 mm. Outside Diameter: 125 mm. Width: 22 mm. Closure: Open. Bore type: Straight. Rolling elements: Ball. Contact Angle: 15°. Cage Type: one-piece machined, inner-ring centred. Cage Material: laminated phenolic resin. Preload: Light (L). Precision Class: P6 (ISO Class 6, ABEC 3, RHP class code EP3). Series: ISO series 10 (70xx). Bearing Material: carbon chrome bearing steel, BS970 534A99/535A99 or SAE 52100. The carton also carries the Fafnir-scheme designation 2MM9116WI CR.

Decoding the designation

7016 — ISO dimension series 10, bore code 16, giving 80 x 125 x 22 mm.

C — 15° contact angle, cross-confirmed by the Fafnir 2MM prefix on the carton designation.

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

SU — single universally ground, so any two bearings of this designation pair back-to-back, face-to-face or in tandem without shims.

L — light preload.

P6 — ISO Class 6, ABEC 3, RHP class code EP3.

Load ratings

Dynamic Load Rating Cr: 58.5 kN (58,500 N). Static Load Rating C0r: 55.5 kN (55,500 N). Maximum recommended operating temperature: 120 °C, set by the laminated phenolic cage. Lubricant: Grease or oil.

What these specs mean in practice

A 15° contact angle sits at the high-speed, low-thrust end of the angular contact range: it carries less axial load than a 25° bearing of the same envelope and runs faster and cooler. An inner-ring-centred one-piece phenolic cage is light, retains an oil film well and keeps the cage located by the faster-moving ring. Light preload keeps running torque and heat generation down while removing internal play, the usual choice for spindles that prize accuracy over stiffness. Universal face control means the ring faces are ground so that the light preload comes up on clamping, with no measured spacers.

Quantity and configuration

Unit Quantity: 1 Pc. Number of Rows: 1. Sets of two, three or four are built by stacking identical universally ground parts; the arrangement is read from the marking on the outer ring face.

Thrust direction

A single-row angular contact ball bearing takes thrust in one direction. A pair mounted back-to-back or face-to-face locates the shaft in both directions; in tandem both rows share thrust in the same single direction.

Mounting data

Shaft abutment diameter d1: 87 mm minimum. Housing abutment diameter D1: 118 mm maximum. Outer ring abutment D2: 120 mm maximum. Chamfer r: 1.5 mm minimum. Chamfer r1: 0.6 mm minimum. Effective load centre a: 24.7 mm. Internal free volume: 36.4 cm³. PCD of lubrication jets: 96.5 mm. Mass: 0.851 kg.

Interchange guidance

A same-envelope 15° light-preload universally ground bearing at ISO Class 6 substitutes directly. Parts sharing the 80 x 125 x 22 mm envelope at 25°, at a different preload letter, or at a different precision class are related sizes, because mounted stiffness and speed capability differ.
