How the OH-3072-H model number is decoded
oil reaches the interface through the M 6 duct connection into distribution grooves, so the 29,000 g sleeve can be floated off the 340 mm shaft instead of being pressed or pulled the OD-to-bore ratio is 1.17: the 420 mm sleeve OD is only 30 mm of section beyond the 360 mm seat, leaving room for the bearing outer ring without enlarging the housing bore the HM 3072 lock nut carries size index 3072, matching the bore-code family of the 360 mm seat; the nut engages the Tr 360x5 sleeve thread over its full width for controlled drive-up the catalogue pairs this seat with the HMV 72E hydraulic nut (size 72); at 29,000 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone this sleeve mounts a bearing with a 360 mm tapered bore onto a plain 340 mm shaft; the 420 mm outside diameter and 188 mm width define the tapered seat the bearing is driven onto the 340 mm shaft size is the domain of rolling-mill, paper-machine and marine equipment — the oil ducts and the HMV 72E hydraulic nut are essential at this scale OH marks the dismountable execution for the 360 mm bore class: the same ducts that eased mounting reverse the fit at overhaul, avoiding the shaft damage a mechanical puller causes at this size dimensionally this sleeve belongs to the oil-injection OH 30 range for 230..K spherical roller bearings; the 420 mm OD and 188 mm width follow the ISO 2982-1 boundary plan for that series hardware on this row: the HM 3072 lock nut and the MS 3072 locking clip; SKF lists the HMV 72E hydraulic nut for mounting and dismounting typical applications include paper machine roll and cylinder journals, gearbox input and output shafts and mining crusher and screen exciter shafts adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 360 mm bore bearing on a 340 mm shaft in mining crusher and screen exciter shafts the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the HM 3072 nut kit identity for this seat: sleeve OH 3072 H for a 340 mm shaft, 360x420x188 mm taper, Tr 360x5 thread, HM 3072 nut with MS 3072 clip, drive-up tool HMV 72E, catalogue mass 29,000 g
Typical equipment & failure modes
Common applications
- marine winch and deck machinery shafts
- paper machine roll and cylinder journals
- cement plant kiln and mill trunnion drives
- food processing line drive shafts
Known failure patterns
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
- 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
- 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
- interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
Selection pitfalls — read before you substitute
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
- over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
- mounting with the HMV 72E hydraulic nut but without injecting oil first overloads the Tr 360x5 thread and can seize the nut
Frequently asked questions
What shaft size does the OH-3072-H adapter sleeve fit?
OH-3072-H (OH 3072 H) mounts on a plain metric shaft of 340 mm and carries a bearing with a 360 mm tapered (K) bore; sleeve OD is 420 mm and width 188 mm.
What does the OH 3072 H designation mean?
OH identifies an oil-injection sleeve with ducts for hydraulic mounting in the OH30 series; the size code encodes the 360 mm tapered bore (bore code × 5 mm). The trailing H marks the hydraulic execution.
What is supplied with the OH-3072-H?
The kit contains the HM 3072 lock nut and MS 3072 locking clip. The HMV 72E hydraulic nut is the associated mounting tool.
How much does the OH-3072-H adapter sleeve weigh?
The listed mass is 29,000 g for the sleeve assembly at 360x420x188 mm — about 154.3 g per millimetre of sleeve width.
How is the OH-3072-H mounted on the shaft?
Inject mounting oil through the M 6 duct, drive the sleeve with the HMV 72E hydraulic nut, measure the axial displacement for the 360 mm seat, then lock with the HM 3072 nut and MS 3072 clip.
