Product Description

What this part is

Fafnir 2MM214WI-SUH super-precision angular contact ball bearing, made by The Timken Company. Series: 200WI. Bore: 70 mm. Outside Diameter: 125 mm. Bearing Width: 24 mm. Total Width: 24 mm. Number of Rows: 1. Rolling Elements: Ball, steel. Bore Type: Straight. Closure Type: Open. Design Units: Metric.

Decoding the designation

Contact Angle: 15°. Precision Rating: ISO P4S (ABEC 7/9). Preload: Heavy. Cage Type: CR – Phenolic Outer Land Riding Cage. Cage Material: Phenolic. Arrangement: SUH, single universally ground for heavy preload. World Part Number: 7214C-T-P4S-SUH. Searchable variants: 2MM214WICRSUH, 2MM214WI SUH, 2 MM 214 WI CR SUH.

Ratings and speed

Dynamic Radial Load Rating (C1, one million revolutions): 84,200 N (18,900 lbf). C1 ISO Dynamic Radial Rating per row: 76,500 N (17,200 lbf). Static Radial Load Rating (C0): 60,000 N (13,400 lbf). Limiting Speed, grease: 11,400 rpm. Limiting Speed, oil: 22,800 rpm.

What these specs mean in practice

A 15° contact angle favours speed and radial stiffness over thrust capacity, so this execution suits high-speed machine tool spindles. A 25° bearing on the same envelope carries more thrust and turns slower. Heavy preload raises axial and radial rigidity and holds shaft position more tightly under load. The phenolic outer-land-riding cage is light and runs quietly at speed. ISO P4S is a tighter tolerance grade than P4, giving closer running accuracy and lower vibration.

Mounting dimensions

Shaft Backing Shoulder Diameter: 80.3 mm. Housing Backing Shoulder Diameter: 115.8 mm. Maximum Shaft Fillet Radius: 1.5 mm. Outer Ring To Clear Radius: 1.5 mm.

Quantity and configuration

Unit Quantity: 1 Pc. Single universally ground bearing, ground so that it mounts alone or stacks with matching SUH bearings in a duplex or triplex set.

Interchange guidance

SKF 7214 CDGC/P4A shares the envelope, the 15° contact angle and the heavy preload class. Timken’s own world designation for this bearing is 7214C-T-P4S-SUH. A 7214 AC or 7214 E part is the 25° execution on the same envelope, which makes it a related size rather than an interchange.
