How the OH-30-530-H model number is decoded

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 HM 30/530 nut on the Tr 530x6 thread advances 6 mm and takes out roughly 0.5 mm of clearance oil reaches the interface through the M 8 duct connection into distribution grooves, so the 105,000 g sleeve can be floated off the 500 mm shaft instead of being pressed or pulled the OD-to-bore ratio is 1.19: the 630 mm sleeve OD is only 50 mm of section beyond the 530 mm seat, leaving room for the bearing outer ring without enlarging the housing bore the sleeve wall is 50 mm thick at the small end — 9.4% of the 530 mm bore — thin enough to contract evenly onto the 500 mm shaft while keeping the seat round under the clamping load a width-to-bore ratio of 0.50 gives a 265 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 500 mm shaft is purely frictional the 500 mm shaft size is the domain of rolling-mill, paper-machine and marine equipment — the oil ducts and the HMV 106E hydraulic nut are essential at this scale OH marks the dismountable execution for the 530 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 630 mm OD and 265 mm width follow the ISO 2982-1 boundary plan for that series hardware on this row: the HM 30/530 lock nut and the MS 30/600-530 locking clip; SKF lists the HMV 106E hydraulic nut for mounting and dismounting typical applications include paper machine roll and cylinder journals, electric motor and generator 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 530 mm bore bearing on a 500 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 30/530 nut kit identity for this seat: sleeve OH 30/530 H for a 500 mm shaft, 530x630x265 mm taper, Tr 530x6 thread, HM 30/530 nut with MS 30/600-530 clip, drive-up tool HMV 106E, catalogue mass 105,000 g

Typical equipment & failure modes

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
• 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
