How the H-222 model number is decoded
the annular envelope between 110 mm bore and 145 mm OD is about 7,010 mm² in cross section, which sets the 1,800 g mass at steel density for the 63 mm-long slit bush the M 110x2 thread spans about 31.5 nut turns across the 63 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 110 mm seat the OD-to-bore ratio is 1.32: the 145 mm sleeve OD is only 17.5 mm of section beyond the 110 mm seat, leaving room for the bearing outer ring without enlarging the housing bore mounting and dismounting stay purely mechanical: the KM 22 nut drives the taper home, and backing the nut off releases the 110 mm seat without oil-injection tooling the KM 22 lock nut carries size index 22, matching the bore-code family of the 110 mm seat; the nut engages the M 110x2 sleeve thread over its full width the 100 mm seat is heavy enough that clearance is set by measured drive-up on the M 110x2 thread, yet light enough that a two-person crew can still mount it conventionally the plain H designation denotes the basic sleeve kit; locking relies on the MB 22 washer whose inner tab engages the sleeve thread groove and whose outer tabs bend into the KM 22 nut slots the H2 block is one of the ISO 2982-1 dimension plans; at this seat it means a 145 mm sleeve OD and the M 110x2 thread shared with the adjacent bore steps the catalogue row bundles the KM 22 lock nut and the MB 22 locking washer and references the HMV 22E hydraulic nut for the 110 mm seat typical applications include marine winch and deck machinery shafts, food processing line drive shafts and cement plant kiln and mill trunnion drives adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 110 mm bore bearing on a 100 mm shaft in cement plant kiln and mill trunnion drives the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KM 22 nut ordering digest — H 222: 100 mm plain shaft to 110 mm tapered bore, sleeve 145 mm OD and 63 mm wide, thread M 110x2, supplied with KM 22 nut with MB 22 washer, drive-up tool HMV 22E; listed mass is 1,800 g
Typical equipment & failure modes
Common applications
- paper machine roll and cylinder journals
- marine winch and deck machinery shafts
- mining crusher and screen exciter shafts
- electric motor and generator shafts
Known failure patterns
- over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
- greasing the tapered seat or shaft destroys the dry friction the joint relies on; a lubricated taper can let the whole sleeve spin under load
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
Selection pitfalls — read before you substitute
- over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
Frequently asked questions
What shaft size does the H-222 adapter sleeve fit?
H 222 is listed for a 100 mm plain shaft; its tapered bore accepts 110 mm K-suffix bearings, the sleeve measures 145 mm OD and 63 mm wide.
What does the H 222 designation mean?
H 222: H-series metric adapter sleeve in the H2 dimension plan; the code resolves to a 110 mm tapered bore and a 100 mm shaft.
What is supplied with the H-222?
Supplied hardware is the KM 22 lock nut and MB 22 locking washer. Drive-up is done with the HMV 22E hydraulic nut.
How much does the H-222 adapter sleeve weigh?
It weighs 1,800 g; the figure is the sleeve-only catalogue mass, with the KM 22 nut counted on the same product row but the hydraulic tool ordered separately.
How is the H-222 mounted on the shaft?
Slide the sleeve onto the 100 mm plain shaft against the abutment, fit the bearing, turn the KM 22 nut with a hook spanner until the measured clearance drop matches the table, and lock it with one MB 22 tab.
