TorringtonSpherical Roller Bearing – 1:12 Tapered Bore, 80 mm ID, 140 mm OD, 33 mm Width, Open, C3 Clearance, W33 Lubrication Groove

Product Description

What this part is: Torrington 22216KCJW33C3 double-row spherical roller bearing. Bore: 80 mm. Outside diameter: 140 mm. Width: 33 mm. Series: 222, ISO dimension series 22216. Bore form: 1:12 tapered. Closure: open both faces. Torrington is a Timken brand. Decoding the designation: K: 1:12 tapered bore for adapter-sleeve mounting. W33: annular lubrication groove in the outer ring with three radial feed holes. C3: internal clearance greater than normal. CJ: Torrington design designation. Searchable forms include 22216KCJW33C3, 22216 K CJ W33 C3, 22216CKJ, 22216KVJ, 22216CCKJ and 22216K. What these specs mean in practice: Two rows of barrel rollers run on a common spherical outer raceway, so the bearing carries heavy radial load with thrust in both directions and self-aligns to shaft deflection and housing misalignment. C3 clearance leaves more running clearance than the standard class, which suits the tight fit produced by drive-up on a sleeve taper and hot-running service. Lubrication provision: The W33 outer ring carries a circumferential groove and three radial holes, so grease or oil is fed directly to the rolling elements through the housing. That supports scheduled relubrication in service without dismounting. Quantity and configuration: One bearing, two rows of rollers, tapered bore. Fitting notes: The 1:12 tapered bore mounts on an adapter sleeve: the matching sleeve is an H316, which seats this 80 mm bore on a 70 mm shaft and is secured with a locknut and lock washer. Shaft backing shoulder diameter: 95 mm. Housing backing shoulder diameter: 129 mm. Maximum shaft fillet radius: 2 mm. Drive-up along the sleeve taper sets the mounted radial clearance. Interchange guidance: Tapered-bore C3 crosses in the same 80 x 140 x 33 mm size: Timken 22216KEJW33C3, SKF 22216 EK/C3, FAG 22216-E1-XL-K-C3, NSK 22216EAKE4C3. A straight-bore 22216 is not a substitute, because it mounts directly on the shaft instead of on a sleeve.
