How the 22213 model number is decoded
In the 22200-series (ISO 15 dimension series) the leading 2 marks a double-row spherical roller and the last two digits of 22213 encode the bore: code 13 = 65 mm (code × 5 from 04 upward). The ISO 15 envelope is 120 mm outside diameter and 31 mm width — 2.559 × 4.724 × 1.22 in, with a 27.5 mm radial section height. Two rows of symmetrical barrel rollers on a common sphered outer raceway self-align to shaft deflection while carrying heavy radial load and bidirectional axial load. Typical catalogue practice for a rotating inner ring is a k5 shaft seat, H7 housing and C3 internal clearance; K variants use a 1:12 tapered bore on an adapter sleeve — verify against the mounting arrangement.
Typical equipment & failure modes
Common applications
- vibrating screens, feeders and shakeout machines
- paper machine felt and press rolls
- industrial gearbox and drive shafts
- elevator winches and hoist drums
- process crane travel wheels
Known failure patterns
- water and grit pitting of open bearings in mining and pulping duty after the housing seals degrade
- unloaded-row scuffing when pure thrust exceeds the catalogue axial capacity and one roller row unloads completely
- thermal seizure when an interference shaft fit plus hot running removes all residual radial clearance from a CN bearing
- raceway and roller spalling after the L10 life or from sustained overload and shock in crusher duty
- roller smearing and skid marks when the radial load falls below the minimum load needed to drive the roller set
Selection pitfalls — read before you substitute
- On this 65 mm-bore 22213, specify C3 clearance as the default for an interference inner-ring fit and verify residual play after mounting; a medium-section row that ran free on the bench can be fully clamped at operating temperature on the 65 mm shaft.
- The 222 medium series at 65 mm bore (120×31 mm, 27.5 mm section) is the default general-purpose spherical row; on the same bore a 22313 is larger and wider with far higher load rating — do not swap a failed 22313 down to a 22213 without re-rating life.
- Before fitting 22213, machine the 65 mm shaft seat and 120 mm housing bore with a relief or small fillet so nothing bridges the bearing chamfer; the 31 mm-wide rings only load correctly when the full faces abut, and a large radius pinches the 27.5 mm radial section.
- On a K tapered bore with adapter sleeve, tighten the KM locknut to drive the 22213 up the sleeve, rotating the inner ring, and stop on residual clearance — measured with feelers at the unloaded rollers — not on torque alone; then lock the tab washer so the 65 mm seat cannot creep.
- Read the damage pattern on a removed 22213: spalling concentrated on one side of the 120 mm outer race points to misalignment or thrust overload, while uniform roller-end smearing means minimum-load skidding — the two failures demand opposite corrections.
- Press 22213 using the right ring: force on the inner ring for an interference shaft fit and on the outer ring for a housing fit — transmitting mounting force through the barrel rollers brinells the sphered raceways of the 120 mm assembly.
- Match the cage to the duty: the E/CC stamped window-steel cage is the standard for general 22213 service, while the machined brass CA cage is preferred for heavy shock and vibratory applications — never replace a CA row with a CC row in a screen or crusher without re-rating.
Frequently asked questions
What are the dimensions of a 22213 spherical roller bearing?
A 22213 double-row spherical roller bearing per ISO 15 has a 65 mm bore, 120 mm outer diameter and 31 mm width (2.559 × 4.724 × 1.22 in), a 27.5 mm radial section and roughly 1264 g geometry-based estimated mass; catalogue masses vary with cage and design.
How does the 22213 bore code work?
The leading 2 in 22213 denotes a double-row spherical roller, the middle digits give the ISO 15 dimension series, and the last two digits are bore code 13: 13 × 5 = 65 mm. The 120 mm OD and 31 mm width come from the dimension series (22200), not from the bore code alone.
How much misalignment can a 22213 accommodate?
Thanks to the sphered outer ring raceway, 22213 normally accommodates angular misalignment of around 1° under load (up to about 2° in favourable, lightly loaded conditions); the permissible value is smaller under full load and depends on clearance and cage design, so check the catalogue figure for the actual duty.
What is the difference between 22213 and 22213K?
The plain 22213 has a cylindrical bore for a straight shaft seat. The K suffix denotes a 1:12 tapered bore, normally mounted on an H3xx adapter sleeve over a commercial shaft (or directly on a tapered journal); the bearing is driven up the sleeve to a specified residual clearance and locked with a KM nut and tab washer.
Should the 22213 be ordered with CN, C3 or C4 clearance?
Use C3 as the usual default when the rotating inner ring has an interference fit, because the fit plus thermal expansion reduces residual play; choose C4 (often with a vibratory cage design) for screens and feeders; order CN mainly for loose fits on stationary shafts or split housings. A W33 outer-ring lubrication groove is a separate, commonly combined option.
