How the 22219 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 22219 encode the bore: code 19 = 95 mm (code × 5 from 04 upward). The ISO 15 envelope is 170 mm outside diameter and 43 mm width — 3.74 × 6.693 × 1.693 in, with a 37.5 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
- jaw and cone crusher eccentric shafts
- paper machine drying cylinders
- large gear drives and mill pinions
- heavy conveyor drum pulleys
- cement and aggregate processing machinery
Known failure patterns
- fretting corrosion on a tapered-bore sleeve seat when drive-up is insufficient and the inner ring works on the adapter
- lubricant starvation and cage wear where the relubrication interval ignores the slow-speed, dirty operating regime
- 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
Selection pitfalls — read before you substitute
- The large 95 mm-bore 22219 mounts with real force: use induction heating or hydraulic drive-up on the tapered seat, measure residual clearance in micrometres, and plan lifting fixtures — the 43 mm double-row assembly cannot be drifted into position without brinelling.
- The 222 medium series at 95 mm bore (170×43 mm, 37.5 mm section) is the default general-purpose spherical row; on the same bore a 22319 is larger and wider with far higher load rating — do not swap a failed 22319 down to a 22219 without re-rating life.
- Before fitting 22219, machine the 95 mm shaft seat and 170 mm housing bore with a relief or small fillet so nothing bridges the bearing chamfer; the 43 mm-wide rings only load correctly when the full faces abut, and a large radius pinches the 37.5 mm radial section.
- On a K tapered bore with adapter sleeve, tighten the KM locknut to drive the 22219 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 95 mm seat cannot creep.
- Read the damage pattern on a removed 22219: spalling concentrated on one side of the 170 mm outer race points to misalignment or thrust overload, while uniform roller-end smearing means minimum-load skidding — the two failures demand opposite corrections.
- Order clearance for the mounting method: an interference fit on a rotating inner ring plus thermal growth eats into CN play, so most industrial 95 mm-bore mounts use C3, vibrating screens use C4, and CN is mainly for loose/split-housing fits — the designation suffix states the class.
- Specify W33 when the 43 mm-wide bearing must be relubricated in place: it is the outer-ring annular groove with lubrication holes; without W33 grease only reaches the contacts through the shaft or housing arrangement.
Frequently asked questions
What are the dimensions of a 22219 spherical roller bearing?
A 22219 double-row spherical roller bearing per ISO 15 has a 95 mm bore, 170 mm outer diameter and 43 mm width (3.74 × 6.693 × 1.693 in), a 37.5 mm radial section and roughly 3425 g geometry-based estimated mass; catalogue masses vary with cage and design.
How does the 22219 bore code work?
The leading 2 in 22219 denotes a double-row spherical roller, the middle digits give the ISO 15 dimension series, and the last two digits are bore code 19: 19 × 5 = 95 mm. The 170 mm OD and 43 mm width come from the dimension series (22200), not from the bore code alone.
How much misalignment can a 22219 accommodate?
Thanks to the sphered outer ring raceway, 22219 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 22219 and 22219K?
The plain 22219 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 22219 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.
