RHP7016CTAngular Contact Ball Bearing 80x125x22 mm 15° Phenolic Cage ISO Series 10

Product Description

What this part is

RHP 7016CT single-row angular contact ball bearing. Bore: 80 mm. Outside Diameter: 125 mm. Overall Width: 22 mm. Contact Angle: 15°. Cage Material: laminated phenolic resin. Cage Type: machined, outer-ring guided. Closure Type: open on both faces. Rolling Elements: carbon chrome bearing steel balls. Series: RHP 70, ISO dimension series 10. Number Of Rows: 1. Precision Class: P0, RHP class code EP1, ISO normal class.

Decoding the designation

Type 7: single-row angular contact ball bearing. Dimension series 0: ISO series 10. Bore code 16: 80 mm bore. Contact angle C: 15°. Cage T: laminated phenolic resin. The alternate carton designation 7016X2EP1 gives the same angle in the RHP B-series scheme, X2 being 15°, and EP1 the British Standard code for normal tolerance class. The form 7016CTR carries TR, phenolic guided on the outer ring land.

Load ratings

Dynamic Load Rating (Cr): 58.5 kN. Static Load Rating (C0r): 55.5 kN. Those are the RHP catalogue figures for the 7016C ball complement and raceway geometry.

What these specs mean in practice

A 15° contact angle is the speed-biased choice in this family. The shallow load line keeps ball centrifugal and gyroscopic effects low, so the bearing reaches a higher limiting speed and runs cooler than a 25° execution on the same envelope, in exchange for axial capacity and axial stiffness.

The phenolic laminate cage is the other speed-oriented feature. Laminated fabric is lighter than machined brass and holds an oil film well against the balls, which suits oil-mist and grease-for-life spindle service and runs quietly. Guidance on the outer ring land keeps the cage running true at speed. Maximum Operating Temperature: 120 °C, set by the phenolic.

Quantity and configuration

Unit Quantity: 1 Pc. The designation carries no universal-grinding code and no preload letter, so the faces are ground to standard single-bearing dimensions rather than to a matched-set stack height.

Thrust direction

A single-row angular contact ball bearing carries thrust in one direction. Axial load in the opposite direction is taken by a second bearing opposing this one, or by another element in the shaft stack.

Mounting data

Inner ring abutment diameter, d1 min: 87 mm. Outer ring abutment diameters: D1 max 118 mm, D2 max 120 mm. Chamfer dimensions: r min 1.5 mm, r1 min 0.6 mm. Effective Load Centre (a): 24.7 mm. Internal free volume: 36.4 cm³. PCD of lubrication jets: 96.5 mm. Mass: 0.851 kg. The bearing is directional: the wide land face of the outer ring is the back face and takes the thrust.

Interchange guidance

7016C is the ISO base designation for a 15° angular contact bearing on this envelope, and 2MM9116WI is the Fafnir-scheme number for the same 15° position. Same-envelope bearings differing in contact angle, preload grade or tolerance class — 7016A5 at 25°, the universally ground and duplex-ground preloaded forms, and the P4, P3 and P2 super-precision classes — are related sizes rather than interchanges.
