NTN7212CTP5Angular Contact Ball Bearing – 60 x 110 x 22 mm, 15° Contact Angle, ABEC 5, Machined Phenolic Cage

Product Description

What this part is

NTN 7212CTP5, a single-row angular contact ball bearing. Bore: 60 mm. Outside Diameter: 110 mm. Overall Width: 22 mm. Contact Angle: 15°. Precision Class: P5 (ABEC 5). Number Of Rows: 1. Rolling Elements: Ball. Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Bearing Material: Chrome steel. Closure Type: Open. Bore Type: Straight. Internal Clearance: CN. Series: 7200. Country of Origin: Japan.

Decoding the designation

Contact Angle: 15°, from the C. Cage Material: Phenolic, from the T. Precision Class: P5, which is ABEC 5. Base Number: 7212. The carton also carries the Fafnir cross 2MM212WI-CR, and that designation reads the same two specs independently: 2MM is 15° on the Fafnir scheme and CR is the phenolic outer-ring land-riding cage.

What these specs mean in practice

Dynamic Load Rating: 53.5 kN (12,027 lbf). Static Load Rating: 43.5 kN (9,779 lbf). Limiting Speed: 15,000 rpm. Operating Temperature Range: −40 °C to +120 °C. A 15° contact angle carries the load path close to radial, which is what supports a 15,000 rpm limit on a 60 mm bore — the highest-speed choice of the standard angular contact angles on this envelope. ABEC 5 tightens bore, outside-diameter and running-accuracy tolerances beyond a standard P0 bearing, so the shaft locates more precisely and the assembly runs with less induced vibration. The machined phenolic cage rides on the outer-ring land rather than being carried by the balls, so ball-to-pocket forces stay low at speed, and the phenolic absorbs and releases lubricant as it runs.

Quantity and configuration

Unit Quantity: 1 Pc. Item Weight: 1.7 lb. Internal Clearance: CN. The designation carries no preload or universal-matching code, so this is a standard clearance-set single bearing rather than a universally ground piece from a matched set. Harmonization Code: 8482.10.50.28.

Interchange guidance

Cross-Reference 1: 7212CP5 — the same bearing designation without the cage code called out. Cross-Reference 2: Fafnir 2MM212WI-CR — 60 x 110 x 22 mm at 15° with a phenolic outer-land-riding cage, held to the tighter Fafnir MM precision range, so it is an upward substitution rather than an identical execution. Cross-Reference 3: 7212B — related size, the same 60 x 110 x 22 mm envelope at a 40° contact angle. Searchable variants of this designation: 7212CTP5, 7212-C-T-P5, 7212 C T P5, 7212CT, 7212C and 7212.
