The Koyo 21317RKC3FY is a spherical roller bearing in the 21300 series with a 1:12 tapered bore. The spherical outer raceway lets the bearing self-align under shaft deflection or housing misalignment.
21317 — 213 series spherical roller bearing, bore code 17 = 85 mm bore, 180 mm OD, 41 mm width.
R — Koyo R-type internal design with machined brass cage.
K — tapered bore, taper 1:12.
C3 — radial internal clearance greater than normal.
Bore Diameter: 85 mm (large end of taper). Outside Diameter: 180 mm. Overall Width: 41 mm. Bore Type: Tapered 1:12. Rolling Elements: Spherical Roller. Cage Material: Brass. Internal Clearance: C3. Closure Type: Open.
The tapered bore allows the bearing to be drawn up on an adapter sleeve onto a plain shaft, and the drive-up sets the final running clearance. C3 gives extra clearance margin for that reduction.
Related part: H317 adapter sleeve (75 mm shaft seat), with KM17 locknut and MB17 lock washer.
Unit Quantity: 1 Pc.
Same 85 x 180 x 41 mm envelope with 1:12 tapered bore: SKF 21317 EK, FAG 21317-E1-K, NSK 21317EAK, each in its C3 clearance execution.
