How the 23022 model number is decoded

In the 23000-series (ISO 15 dimension series) the leading 2 marks a double-row spherical roller and the last two digits of 23022 encode the bore: code 22 = 110 mm (code × 5 from 04 upward). The ISO 15 envelope is 170 mm outside diameter and 45 mm width — 4.331 × 6.693 × 1.772 in, with a 30.0 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 m6 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

Selection pitfalls — read before you substitute

• The large 110 mm-bore 23022 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 45 mm double-row assembly cannot be drifted into position without brinelling.
• In vibrating-screen and feeder duty the 230 row is a common pick: at 110 mm bore the 23022 gives a 170×45 mm envelope with a wide, stiff section, but it must then run C4 clearance with a vibratory-rated cage — a standard CN row with a plain stamped cage will gall and fail early under the same duty.
• Grease life on the 23022 is set by the slow, dirty regime it usually works in: relubricate through the W33 groove until old grease flushes clear of the full 45 mm-wide double row, because the 30.0 mm section gives contamination little room to fall away from the 170 mm raceway on its own.
• Before fitting 23022, machine the 110 mm shaft seat and 170 mm housing bore with a relief or small fillet so nothing bridges the bearing chamfer; the 45 mm-wide rings only load correctly when the full faces abut, and a large radius pinches the 30.0 mm radial section.
• On a K tapered bore with adapter sleeve, tighten the KM locknut to drive the 23022 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 110 mm seat cannot creep.
• Read the damage pattern on a removed 23022: 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.
• Spherical rollers need a minimum radial load to keep the rollers driven — as a rule of thumb about 2% of the basic dynamic load rating; an unloaded 23022 on an idler or in a cold-start drive will skid and smear, so add preload, reduce the bearing size or use a sealed grease-filled variant.
• Choose the bore type deliberately: plain 23022 takes a cylindrical seat, while the K variant has a 1:12 tapered bore and mounts on an adapter sleeve (H3xx series) over a plain commercial shaft or directly on a tapered journal — the two mounting procedures are not interchangeable.
