Fafnir 2MM9311WI-CR-DUL super precision angular contact ball bearing, supplied as a factory-matched duplex pair. Bore Diameter: 55 mm. Outside Diameter: 80 mm. Overall Width: 13 mm. 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. Series: 2MM9300. Base Number: 2MM9311WI. GTIN: 087796206076.
2MM — 15° contact angle, Fafnir super precision range.
9311 — 9300WI series, ISO 719-series envelope, 55 mm bore.
WI — low shoulder on both rings.
CR — phenolic cage.
DU — duplex set, universally ground for flush faces.
L — light preload.
Dynamic Load Rating: 21,800 N. Static Load Rating: 18,500 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: 16,600 rpm grease; 33,200 rpm oil. Lubricant: grease or oil. The phenolic cage is light and damps cage chatter, which is what supports those speeds on a 55 mm bore.
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 — the set runs under preload.
Shaft Backing Shoulder Diameter: 60.4 mm (2.380 in). Housing Backing Shoulder Diameter: 75.2 mm (2.960 in). Maximum housing fillet radius the bearing corners clear: 1 mm (0.039 in).
Unit Quantity: 2 Pcs. Arrangement: duplex pair, universally ground, light preload. Preload: Light.
