Contact Angle: 15°. Precision Class: ABEC 7/9 / P4S. Cage Material: Phenolic. Rolling Elements: Ball. Bearing Material: Bearing Steel. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1.

Decoding the designation

2MM — 15° contact angle, Fafnir super precision range.

214 — 200WI series, ISO 72-series envelope, 70 mm bore, giving the 7214 boundary dimensions.

WI — low shoulder on both rings.

CR — phenolic cage.

SU — single bearing, universally ground.

L — light preload when mounted as a set.

What these specs mean in practice

Dynamic Load Rating: 84,200 N. Static Load Rating: 60,000 N. A 15° contact angle favours speed and radial stiffness, carrying less thrust per row than a 25° execution and running cooler at the same shaft speed.

Limiting Speed: 11,400 rpm grease; 22,800 rpm oil. Lubricant: grease or oil. Item Weight: 1.074 kg (2.37 lb).

Precision Class: ABEC 7/9 / P4S gives tight raceway and face runout, for spindle work where shaft position has to hold under load. Internal Clearance: N/A — a universally ground bearing is set by preload when stacked.

Mounting data

Shaft Backing Shoulder Diameter: 80.3 mm (3.160 in). Housing Backing Shoulder Diameter: 115.8 mm (4.560 in). Maximum housing fillet radius the bearing corners clear: 1.5 mm (0.059 in).

Quantity and configuration

Unit Quantity: 1 Pc. Universally ground with flush faces, so it stacks against another SUL bearing back-to-back, face-to-face or in tandem and takes up light preload without shimming.
