Fafnir RM209WICR single-row angular contact ball bearing, Timken Fafnir 200WI spindle series. Bore Diameter: 45 mm. Outside Diameter: 85 mm. Overall Width: 19 mm — the 7209 / 209 envelope. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Ball. Closure Type: Open. Cage Material: Phenolic. Cage Type: Machined, outer-ring guided. Bearing Material: Chrome steel. Series: Fafnir 200WI. Base Number: RM209WI. Unit Quantity: 1 Pc.
209 — 200 dimension series, bore code 09: a 45 mm bore in an 85 mm outside diameter, 19 mm wide.
WI — low shoulder on both rings, the Fafnir spindle angular contact execution. The ball complement seats against the high shoulders, so the bearing carries radial load together with thrust in one direction.
CR — machined phenolic cage riding on the outer-ring lands.
A phenolic cage is light, so cage inertia stays low as the shaft speeds up, and the laminated fabric holds oil in its structure and keeps feeding the ball pockets under thin lubrication. Outer-land guidance holds the cage concentric with the outer ring at speed rather than letting it float on the ball set, which steadies cage motion and keeps running noise down.
A single-row angular contact bearing locates the shaft axially in one direction, so it is used opposed by a second bearing or a shoulder that takes thrust the other way. Closure Type: Open — the raceways are accessible for the housing lubricant, grease or oil alike.
Unit Quantity: 1 Pc. One bearing per listing, faces plain ground.
The Fafnir line is now Timken, so Timken RM209WICR and Fafnir RM209WICR are the same part. Same 45 x 85 x 19 mm envelope, each with its contact angle named: SKF 7209 CD/P4A at 15°, FAG B7209-C-T-P4S-UL at 15°, NSK 7209CTRSULP4 at 15°, NTN 7209UCG/GNP4 at 15°, RHP 7209CTDULP4 at 15°, Koyo 7209C-5GLFGP4 at 15°, SNR 7209CG1UJ74 at 15°. The MRC 7209 shares the envelope at a 29° contact angle and is listed as a related size. Match the angle the spindle was designed around.
