Fafnir 2MM214WI super-precision angular contact ball bearing, made by The Timken Company. Series: 200WI. Bore: 70 mm. Outside Diameter: 125 mm. Bearing Width: 24 mm. Number of Rows: 1. Rolling Elements: Ball, steel. Bore Type: Straight. Closure Type: Open. Design Units: Metric. Material: High carbon chrome bearing steel.
Contact Angle: 15°. Precision Rating: ISO P4S (ABEC 7/9). Preload: Zero. Cage Type: CR – Phenolic Outer Land Riding Cage. Cage Material: Phenolic. World Part Number: 7214C-T-P4S-SUL. Searchable variants: 2MM214WICR, 2MM214WI, 2 MM 214 WI.
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.
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. Zero preload leaves the preload to be set by the mounting, which gives the machine builder control over spindle stiffness and running temperature. 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. Lubricant: grease or oil.
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.
Unit Quantity: 1 Pc. Universally ground single bearing, so it runs alone or stacks with matching 2MM214WI bearings in a duplex or triplex set.
SKF 7214 CD/P4A shares the envelope, the 15° contact angle and the super-precision tolerance grade. Timken’s own world designation for this bearing is 7214C-T-P4S-SUL. 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.
