How the H-2320-E model number is decoded
this sleeve mounts a bearing with a 100 mm tapered bore onto a plain 90 mm shaft; the 130 mm outside diameter and 97 mm width define the tapered seat the bearing is driven onto 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 a width-to-bore ratio of 0.97 gives a 97 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 90 mm shaft is purely frictional the seat taper is 1:12, so each millimetre of axial drive-up removes about 1/12 mm of radial clearance; one turn of the KMFE 20 nut on the M 100x2 thread advances 2 mm and takes out roughly 0.167 mm of clearance the sleeve wall is 15 mm thick at the small end — 15.0% of the 100 mm bore — thin enough to contract evenly onto the 90 mm shaft while keeping the seat round under the clamping load the 90 mm shaft diameter places this in the medium band, where adapter mounting starts to beat press fits because no heating or pressing equipment is needed on site the E suffix marks the variant supplied with the KMFE 20 nut, which carries an integral locking screw — no separate locking washer is needed, and the nut locks itself on the M 100x2 thread dimensionally this sleeve belongs to the wide-section H 23 range sized for 223..K spherical roller bearings; the 130 mm OD and 97 mm width follow the ISO 2982-1 boundary plan for that series the delivery includes the KMFE 20 lock nut, and the HMV 20 E hydraulic nut is the associated drive-up tool typical applications include conveyor pulley and drum bearing seats, quarry conveyor head and tail drums and industrial fan and blower impeller shafts 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 industrial fan and blower impeller shafts the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KMFE 20 nut full specification chain for H 2320 E reads 90 mm shaft / 100 mm seat / 130 mm OD / 97 mm width / M 100x2 / KMFE 20 self-locking nut, drive-up tool HMV 20 E / 2,000 g
Typical equipment & failure modes
Common applications
- mining crusher and screen exciter shafts
- conveyor pulley and drum bearing seats
- electric motor and generator shafts
- rolling mill and steel plant roll seats
Known failure patterns
- the shaft must be within h9 tolerance and free of scoring; an oversize or rough shaft stops the slit sleeve closing down and leaves the grip to the thread alone
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
- interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
- over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
- 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-2320-E adapter sleeve fit?
the fit is 90 mm shaft to 100 mm bearing bore via the 1:12 taper; H-2320-E has a 130 mm outside diameter and a 97 mm overall width.
What does the H 2320 E designation mean?
the letters give the execution and the digits give the bore: H 2320 E belongs to H23, fits 100 mm tapered-bore bearings, and the E marks the KMFE self-locking nut execution.
What is supplied with the H-2320-E?
You receive the sleeve plus KMFE 20 lock nut. One nut turn on the M 100x2 thread advances 2 mm along the 1:12 taper.
How much does the H-2320-E adapter sleeve weigh?
2,000 g for the 97 mm-long slit bush — the equivalent of 20.0 g per millimetre of the 100 mm bore.
How is the H-2320-E mounted on the shaft?
Mount dry and clean: drive the bearing up the 1:12 taper by turning KMFE 20 on the M 100x2 thread, using the HMV 20 E hydraulic nut for force, verify clearance with feeler gauges, then apply the nut-integrated lock.
