How the 32213 model number is decoded
In the 32200-series the last two digits of 32213 encode the bore: code 13 = 65 mm (code × 5 from 04 upward). The ISO 355 envelope is 120 mm outside diameter and 32.75 mm total assembly width T over the separable cone and cup — 2.559 × 4.724 × 1.289 in, with a 27.5 mm radial section height. Tapered rollers carry combined radial and single-direction axial load; bidirectional thrust needs an opposed pair (X face-to-face or O back-to-back) adjusted at fit-up. With a rotating cone on a 65 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore, EP lubrication and a defined end-play setting — verify against the load direction and magnitude.
Typical equipment & failure modes
Common applications
- industrial transmission shafts
- light-truck and van wheel hubs
- final-drive pinion and differential bearings
- commercial gearbox input/output shafts
- conveyor head and tail pulleys
Known failure patterns
- under-preload end play that lets the rollers skid, producing noise and false brinelling
- water and grit pitting in unsealed hubs where the cup-cone joint acts as a debris entry path
- false brinelling from vibration while the axle is stationary during transport
- fretting corrosion on a loose shaft seat when the cone is pressed to an interference that relaxes with wear
- cup creep and housing bore fretting when the outer ring is left without its specified press fit
Selection pitfalls — read before you substitute
- On this 65 mm-bore 32213, thermal growth of the shaft closes up the adjusted clearance; set cold end play around 0.03–0.12 mm and recheck after the first hot run — a medium-series cone that was correct cold on the 65 mm seat can seize hot.
- The 322 medium series at 65 mm bore (120×32.75 mm) gains roller length and load over the 30213 on the same OD; the wider 32.75 mm assembly needs a wider housing shoulder and changes the pinion offset in a differential.
- Before fitting 32213, machine the 65 mm shaft seat and 120 mm housing bore with a relief or small fillet so nothing bridges the bearing chamfer; the 32.75 mm-wide cone and cup only load correctly when the full faces abut, and a large radius pinches the 27.5 mm radial section.
- The 32213 cup drives into the 120 mm housing bore with a sleeve against its outer face only; pressure on the inner ring or cage transfers through the rollers and leaves indentations that become spalls within the 32.75 mm load zone.
- Relubrication for 32213 must reach the rib-roller end contact, not just the 65 mm bore; in a hub repack, work EP grease through the roller set until it exudes at both faces of the 32.75 mm-wide assembly or the sliding rib contact starves first.
- Assign fits by which ring rotates: an interference shaft fit for a rotating cone; if the cup rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
- A single 32213 takes thrust in ONE direction — the rollers roll toward the rib under load, so reverse thrust unloads the contact. For a wheel or pinion use an opposing 322-series pair adjusted against each other.
Frequently asked questions
What are the dimensions of a 32213 tapered roller bearing?
A 32213 single-row metric tapered roller bearing per ISO 355 has a 65 mm bore, 120 mm outer diameter and 32.75 mm total assembly width (2.559 × 4.724 × 1.289 in), a 27.5 mm radial section and roughly 1335 g geometry-based estimated mass; catalogue masses vary with roller and cage design.
How does the 32213 bore code work?
The last two digits of 32213 are bore code 13, giving 13 × 5 = 65 mm bore — the same convention as 6xx ball bearings, starting at code 04 (20 mm). The 120 mm OD and 32.75 mm width come from the ISO 355 diameter and width series, not the bore code alone.
What is the cone and cup of 32213?
Tapered roller bearings are separable: the cone is the inner ring with the tapered rollers and cage, the cup is the outer ring. 32213 denotes a matched cone-and-cup set. They are fitted separately — cone pressed on the shaft, cup in the housing — and adjusted against each other.
How is the preload or clearance of 32213 set?
At fit-up the 65 mm-bore cone is tightened against the cup while the hub is rotated, seated, then backed off to the specified end play — a typical starting range of 0.03–0.12 mm for a 65 mm bore — and locked with shims, a locknut or a spacer. Too tight overheats and seizes the rib; too loose causes skid, noise and early wear. Confirm the exact figure in the hub or axle-maker procedure.
Can 32213 take axial load in both directions?
A single 32213 takes thrust in one direction only — the roller large ends bear against the inner-ring rib under load. Bidirectional axial load requires an opposed pair: X (face-to-face) tolerates misalignment slightly better, O (back-to-back) gives a wider load centre and more moment stiffness.
