Product Description

What this part is

SNFA E230-7PE1UL super-precision angular contact ball bearing. Base Number: E230. Bore: 30 mm. Outside Diameter: 62 mm. Overall Width: 16 mm. Number Of Rows: 1. Rolling Elements: Balls. Bearing Material: Bearing Steel. Closure Type: Open. Bore Type: Straight. Design Units: Metric. Item Weight: 0.46 lbs.

Decoding the designation

Preload: Light, and the faces are universally ground, both given by the UL. Precision Class: ABEC 7 / P4. Running Accuracy — Radial And Axial Runout: P4. Searchable forms of the number: E230-7PE1UL, E230 7PE1 UL, E-230-7-PE-1-UL, E2307PE1UL.

What these specs mean in practice

Dynamic Load Rating: 24 kN. Static Load Rating: 15.6 kN. Light preload removes axial play while keeping running torque and heat generation low, which is what a high-speed spindle position is set up for. P4 tolerances hold radial and axial runout close, so the shaft stays located under load. Cage Material: Phenolic — light, quiet and self-lubricating. Max Temp: 120°C. Min Temp: -30°C.

Quantity and configuration

Unit Quantity: 1 Pc. Mounting Arrangement: Universal — universally ground faces let two or more bearings of the same designation mount back-to-back, face-to-face or in tandem and take up the ground light preload. Preloaded execution, so the bearing is supplied set rather than clearance-graded.

Interchange guidance

Cross-Reference 1: SKF 7206 CD/P4A, the same 30 x 62 x 16 mm envelope at ABEC 7. Cross-Reference 2: Fafnir 2MM206WI-SUL, the same envelope in the Fafnir super-precision range. SNFA is a French super-precision maker, now part of SKF, and the ISO equivalent size for this envelope is a 7206. MPN Variants recorded on this part: E-230-7-PE-1-UL, 2MM206 DU, 7206 P4 UL.
