How the OH-3052-H model number is decoded

the annular envelope between 260 mm bore and 310 mm OD is about 22,384 mm² in cross section, which sets the 13,500 g mass at steel density for the 145 mm-long slit bush a width-to-bore ratio of 0.56 gives a 145 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 240 mm shaft is purely frictional the sleeve wall is 25 mm thick at the small end — 9.6% of the 260 mm bore — thin enough to contract evenly onto the 240 mm shaft while keeping the seat round under the clamping load the OD-to-bore ratio is 1.19: the 310 mm sleeve OD is only 25 mm of section beyond the 260 mm seat, leaving room for the bearing outer ring without enlarging the housing bore oil reaches the interface through the M 6 duct connection into distribution grooves, so the 13,500 g sleeve can be floated off the 240 mm shaft instead of being pressed or pulled at 240 mm the 145 mm-wide seat and its HM 3052 nut are crane-handled components; injection pressure and drive-up distance are logged procedures rather than workshop judgement oil injection is mandatory rather than optional at the 240 mm shaft scale — the OH grooves and M 6 connection are what make the 145 mm taper removable without destroying the seat as part of the oil-injection OH 30 range for 230..K spherical roller bearings, this size keeps series-standard proportions: 145 mm width on a 260 mm bore, so the bearing lands at the catalogue axial position the catalogue row bundles the HM 3052 lock nut and the MS 3052-48 locking clip and references the HMV 52E hydraulic nut for the 260 mm seat typical applications include printing press cylinder journals, textile machine roller shafts and conveyor pulley and drum bearing seats adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 260 mm bore bearing on a 240 mm shaft in conveyor pulley and drum bearing seats the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the HM 3052 nut kit identity for this seat: sleeve OH 3052 H for a 240 mm shaft, 260x310x145 mm taper, Tr 260x4 thread, HM 3052 nut with MS 3052-48 clip, drive-up tool HMV 52E, catalogue mass 13,500 g

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• mounting with the HMV 52E hydraulic nut but without injecting oil first overloads the Tr 260x4 thread and can seize the nut
• mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
• misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
