RHP7024CTP0Angular Contact Ball Bearing – Straight Bore, 120 mm ID, 180 mm OD, 28 mm Width, Open, 15° Contact Angle, Normal P0 Precision, CN Clearance

Product Description

What this part is

RHP 7024CTP0 is a single-row angular contact ball bearing, 120 mm bore, 180 mm outside diameter and 28 mm width. Rings and balls are chrome bearing steel, the cage is machined laminated phenolic and both faces are open. It is a standard-precision bearing, not a super-precision execution.

Decoding the designation

7024 is the ISO 70 dimension series with a 120 mm bore. In the RHP scheme C denotes a 15° contact angle, T a machined laminated phenolic cage guided on the outer ring, and P0 normal precision, equivalent to ABEC 1. The carton also carries the RHP B-series number B7024X2TAEP1. In that scheme X2 confirms the 15° angle and EP1 confirms the P0 precision class, so both the angle and the class are established twice from the carton alone.

What these specs mean in practice

A 15° contact angle favours speed and radial stiffness over thrust capacity. Normal P0 precision suits general machinery and pump and gearbox positions rather than machine tool spindles, and it is the reason this bearing carries a clearance class instead of a ground preload. The machined phenolic cage is light, quiet and tolerant of marginal lubrication, and is rated for continuous service to 120 °C.

Load ratings and speed

Basic dynamic load rating 141 kN and basic static load rating 117 kN. Limiting speed 7,700 rpm on grease and 11,700 rpm on oil. Approximate mass 2.09 kg.

Quantity and configuration

One bearing, supplied singly. The designation carries no duplex or preload code, so the bearing is set to normal CN radial internal clearance and is intended to run against a second bearing or a locating shoulder that takes thrust in the opposite direction.

Fitting notes

A single angular contact ball bearing takes thrust in one direction only, and the high shoulder on the outer ring identifies the loaded face. Rings are pressed on their own faces, never through the ball complement.

Interchange guidance

SKF 7024 CD and FAG B7024-C-T share the envelope, the 15° angle and the phenolic cage. NSK 7024CTRSULP4 shares the envelope and angle but is a ground super-precision preloaded execution at ABEC 7, making it a related size rather than an interchange.
