Fafnir 3MM214WI-CR-DUM super-precision angular contact ball bearing, 200WI spindle series, 70 x 125 x 24 mm. Bore Diameter: 70 mm. Outside Diameter: 125 mm. Overall Width: 24 mm per bearing. Contact Angle: 25°. Precision Class: ABEC 7/9 / P4S. Cage Material: Phenolic. Rolling Elements: Ball. Bearing Material: Chrome steel. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1 per bearing. GTIN: 087796070875.
3 — 25° contact angle.
MM — Fafnir super-precision spindle execution, ISO P4S tolerance class.
214 — 200 series, bore code 14, giving a 70 mm bore.
WI — low shoulder on both rings, the spindle bearing form.
CR — phenolic cage.
DUM — duplex pair, medium preload.
Dynamic Load Rating: 80,200 N per bearing. Static Load Rating: 57,400 N. Limiting Speed: 11,300 rpm grease; 20,600 rpm oil. Lubricant: grease or oil.
A 25° contact angle carries more thrust and less speed than a 15° execution of the same size, which is why this bearing runs to 20,600 rpm on oil. Medium preload sits between the light and heavy grades: more stiffness than light, lower heat generation than heavy. Preload and internal clearance are mutually exclusive, so Internal Clearance: N/A.
The phenolic cage runs quietly at high surface speed and holds lubricant, which suits continuous spindle duty.
Shaft Backing Shoulder Diameter: 80.3 mm (3.160 in). Housing Backing Shoulder Diameter: 115.8 mm (4.560 in). Maximum housing fillet radius that the bearing corners will clear: 1.5 mm (0.059 in).
Unit Quantity: 2 Pcs. Mounting Arrangement: duplex pair, medium preload. The two bearings are ground as a matched set and mount together on one shaft seat.
Timken 7214AC-T-P4S-DUM, SKF 7214 ACD/P4ADGC, FAG B7214-E-T-P4S-DUM, NSK 7214A5TRDUMP4 and RHP 7214ETDUMP4 share the 70 x 125 x 24 mm size, the 25° angle, P4S tolerance and medium preload. A standard-precision 7214AC has the same size and angle at a looser tolerance class.
