Fafnir M218WI angular contact ball bearing, 200WI series. Brand: Fafnir (Timken). Part Number: M218WI. Bore: 90 mm. Outside Diameter: 160 mm. Overall Width: 30 mm. Design Units: Metric. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Chrome bearing steel. Item Weight: 4.84 lbs.
Precision Class: P6. Precision Rating: ABEC 3. The carton designation carries the ISO cross-reference 7218 alongside the P6 class, so this is the P6-tolerance execution of the 218WI rather than the P4S super-precision execution. WI marks a low shoulder on both rings, which is what lets the bearing be assembled with a high ball complement. Cage Material: Phenolic. Series: 200WI, carrying the 7218 envelope of 90 x 160 x 30 mm.
ABEC 3 / P6 holds running accuracy and bore and outside-diameter tolerance closer than a standard-class bearing, which shows up as lower shaft runout and quieter running. The 90 mm bore inside a 160 mm outside diameter is the medium 72-series section, so the bearing carries a heavier load for its bore than a 70- or 719-series part of the same shaft size. The phenolic cage runs light and holds lubricant against the ball pockets.
Unit Quantity: 1 Pc.
Cross-Reference: Timken 7218, on the 90 x 160 x 30 mm envelope. Harmonization Code: 8482.10.50.68.
MPN Variants: M218WI, M-218-WI, M 218 WI, 218WI, 7218 P6.
