Fafnir 2MM218WI-SUL super-precision angular contact ball bearing, built by Timken. Bore: 90 mm. Outside Diameter: 160 mm. Bearing Width: 30 mm. Total Width: 30 mm. Contact Angle: 15°. Precision Class: ISO P4S (ABEC 7/9). Preload: Light. Cage Material: Phenolic. Cage Type: outer-ring land riding, machined. Rolling Elements: steel balls. Closure Type: Open. Number of Rows: 1. Series: 200. Bore Type: Straight.
2MM — Fafnir super-precision spindle execution at a 15° contact angle, ground to ISO P4S.
218 — the 200WI size series, ISO 7218 envelope, 90 x 160 x 30 mm.
WI — low shoulder on both rings.
CR — phenolic outer land riding cage.
SUL — single universally ground bearing, light preload. Faces are ground so any two pieces of the same number stack to the rated preload in any arrangement.
Dynamic Radial Load Rating (C1): 129,900 N. Static Radial Load Rating (C0): 97,900 N. ISO dynamic radial rating per row: 118,000 N. Limiting Speed: 8,900 rpm on grease, 17,800 rpm on oil. Lubricant: grease or oil.
The 72 dimension series carries a heavier cross-section than the 70 series at the same bore, which raises load capacity. A 15° contact angle favours speed and radial stiffness over thrust capacity. Light preload gives the highest running speed and the lowest heat generation of the three grades. The phenolic cage is light, tolerates high surface speed and holds oil in its fabric base.
Unit Quantity: 1 Pc. Single universally ground bearing, mountable alone or stacked with further pieces of the same number back-to-back, face-to-face or in tandem.
Shaft Backing Shoulder Diameter: 102.7 mm. Housing Backing Shoulder Diameter: 148 mm. Maximum Shaft Fillet Radius: 2 mm. Outer Ring To-Clear Radius: 2 mm.
Timken world part number: 7218C-T-P4S-SUL. Manufacturing part number: 2MM218WI SUL. The same bearing is written 2MM218WISUL, 2MM-218-WI-CR-SUL and 2MM218WICRSUL.
