How the H-220 model number is decoded
the 10 mm difference between the 90 mm shaft and the 100 mm nominal seat diameter is bridged by taper contraction as the slit sleeve closes during drive-up, rather than by machining the shaft the OD-to-bore ratio is 1.30: the 130 mm sleeve OD is only 15 mm of section beyond the 100 mm seat, leaving room for the bearing outer ring without enlarging the housing bore the M 100x2 thread spans about 29.0 nut turns across the 58 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 100 mm seat the annular envelope between 100 mm bore and 130 mm OD is about 5,419 mm² in cross section, which sets the 1,400 g mass at steel density for the 58 mm-long slit bush mounting and dismounting stay purely mechanical: the KM 20 nut drives the taper home, and backing the nut off releases the 100 mm seat without oil-injection tooling at 90 mm shaft the sleeve suits mid-size machinery — conveyor pulleys, industrial fans and gearbox output shafts carrying 100 mm bore bearings reading H 220: H marks the standard sleeve execution, the size code encodes the 100 mm tapered bore, and the kit includes the KM 20 nut plus MB 20 washer for positive locking the H2 designation block places it in the light-section H 2 range, commonly paired with 12..K self-aligning ball bearings — every sleeve in the block uses the same bore-code logic, and here the 100 mm tapered bore matches the K-suffix bearing it is ordered for hardware on this row: the KM 20 lock nut and the MB 20 locking washer; SKF lists the HMV 20E hydraulic nut for mounting and dismounting typical applications include industrial fan and blower impeller shafts, electric motor and generator shafts and pump shafts in water and process plants adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 100 mm bore bearing on a 90 mm shaft in pump shafts in water and process plants the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KM 20 nut full specification chain for H 220 reads 90 mm shaft / 100 mm seat / 130 mm OD / 58 mm width / M 100x2 / KM 20 nut with MB 20 washer, drive-up tool HMV 20E / 1,400 g
Typical equipment & failure modes
Common applications
- printing press cylinder journals
- industrial fan and blower impeller shafts
- conveyor pulley and drum bearing seats
- pump shafts in water and process plants
Known failure patterns
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
Selection pitfalls — read before you substitute
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- 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
Frequently asked questions
What shaft size does the H-220 adapter sleeve fit?
the fit is 90 mm shaft to 100 mm bearing bore via the 1:12 taper; H-220 has a 130 mm outside diameter and a 58 mm overall width.
What does the H 220 designation mean?
the letters give the execution and the digits give the bore: H 220 belongs to H2, fits 100 mm tapered-bore bearings, using a separate lock nut and locking element.
What is supplied with the H-220?
You receive the sleeve plus KM 20 lock nut and MB 20 locking washer. One nut turn on the M 100x2 thread advances 2 mm along the 1:12 taper.
How much does the H-220 adapter sleeve weigh?
1,400 g for the 58 mm-long slit bush — the equivalent of 14.0 g per millimetre of the 100 mm bore.
How is the H-220 mounted on the shaft?
Mount dry and clean: drive the bearing up the 1:12 taper by turning KM 20 on the M 100x2 thread, using the HMV 20E hydraulic nut for force, verify clearance with feeler gauges, then apply the MB 20 locking washer.
