Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Balls. Closure Type: Open. Precision Class: ABEC 7 (RHP EP7 / ISO Class 4). Preload: Light. Cage Material: Machined laminated phenolic. Cage Type: Machined, outer-ring guided. Design Units: Metric. Country of Origin: United Kingdom.

Decoding the designation

7213 gives the 72 dimension series and a 65 mm bore. T: machined laminated phenolic cage, outer-ring guided. DU: universally faced pair, so the two pieces of a factory pair mount back-to-back, face-to-face or in tandem, and any two pieces of the designation combine the same way. L: light preload. P4: RHP EP7, equal to ISO tolerance class 4 and ABEC 7. Searchable variants: 7213-T-DUL-P4, 7213 T DUL P4, 7213-T-U-EP7, 7213X2-T-U-EP7, MM213WI-CR-DUL, 7213B.

What these specs mean in practice

The machined laminated phenolic cage is light and outer-ring guided, which gives stable cage rotation at speed and low cage-to-ball friction. Precision Class: ABEC 7 — a tighter tolerance than standard, giving lower running vibration and closer shaft location. Lubricant: grease or oil. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. Material: Chrome bearing steel.

Quantity and configuration

Unit Quantity: 1 Pc. One piece from a factory universally faced pair. Mounting Arrangement: universally faced, for back-to-back, face-to-face or tandem assembly. Internal Clearance: N/A — face grinding sets the axial position on a universally faced preloaded execution.

Interchange guidance
