How the H-2324-E model number is decoded
mass 3,100 g is 25.8 g per mm of bore; the sleeve with its KMFE 24 nut forms the complete 112 mm-wide mounting assembly this sleeve mounts a bearing with a 120 mm tapered bore onto a plain 110 mm shaft; the 155 mm outside diameter and 112 mm width define the tapered seat the bearing is driven onto a width-to-bore ratio of 0.93 gives a 112 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 110 mm shaft is purely frictional the 10 mm difference between the 110 mm shaft and the 120 mm nominal seat diameter is bridged by taper contraction as the slit sleeve closes during drive-up, rather than by machining the shaft the M 120x2 thread spans about 56.0 nut turns across the 112 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 120 mm seat the 110 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 with H 2324 E the locking device lives inside the KMFE 24 nut itself: a friction screw engages the M 120x2 thread, so the outer washer and its bent tab disappear from the assembly within the wide-section H 23 range sized for 223..K spherical roller bearings this is the 110 mm shaft step; neighbouring steps keep the same hardware concept while the taper seat grows to 120x155 mm here the delivery includes the KMFE 24 lock nut, and the HMV 24 E hydraulic nut is the associated drive-up tool typical applications include agricultural machinery axle and PTO shafts, woodworking saw and planer spindles and paper machine roll and cylinder journals adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 120 mm bore bearing on a 110 mm shaft in paper machine roll and cylinder journals the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KMFE 24 nut kit identity for this seat: sleeve H 2324 E for a 110 mm shaft, 120x155x112 mm taper, M 120x2 thread, KMFE 24 self-locking nut, drive-up tool HMV 24 E, catalogue mass 3,100 g
Typical equipment & failure modes
Common applications
- pump shafts in water and process plants
- agricultural machinery axle and PTO shafts
- gearbox input and output shafts
- paper machine roll and cylinder journals
Known failure patterns
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
- driving the bearing via the outer ring during mounting loads the rolling elements; force is always applied through the lock nut on the inner ring
- with no washer as a back-up, a slack locking screw is the only way the KMFE 24 nut can unwind — verify it after the first run
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
Selection pitfalls — read before you substitute
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
- with no washer as a back-up, a slack locking screw is the only way the KMFE 24 nut can unwind — verify it after the first run
- the KMFE 24 self-locking nut must not be replaced with a standard KM nut, which has no integral device to grip the thread
Frequently asked questions
What shaft size does the H-2324-E adapter sleeve fit?
H-2324-E (H 2324 E) mounts on a plain metric shaft of 110 mm and carries a bearing with a 120 mm tapered (K) bore; sleeve OD is 155 mm and width 112 mm.
What does the H 2324 E designation mean?
H identifies a standard metric adapter sleeve in the H23 series; the size code encodes the 120 mm tapered bore (bore code × 5 mm). The E suffix means a KMFE lock nut with integral locking device is supplied.
What is supplied with the H-2324-E?
The kit contains the KMFE 24 lock nut. The HMV 24 E hydraulic nut is the associated mounting tool.
How much does the H-2324-E adapter sleeve weigh?
The listed mass is 3,100 g for the sleeve assembly at 120x155x112 mm — about 27.7 g per millimetre of sleeve width.
How is the H-2324-E mounted on the shaft?
Lubricate the M 120x2 thread lightly, screw the KMFE 24 home, then tighten to the catalogue axial displacement while measuring clearance reduction on the 120 mm bearing, and finally bend set the integral locking screw.
