How the OH-3272-H model number is decoded

for controlled drive-up the catalogue pairs this seat with the HMV 72E hydraulic nut (size 72); at 60,500 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone a width-to-bore ratio of 0.83 gives a 299 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 340 mm shaft is purely frictional the Tr 360x5 thread spans about 59.8 nut turns across the 299 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 360 mm seat this sleeve mounts a bearing with a 360 mm tapered bore onto a plain 340 mm shaft; the 460 mm outside diameter and 299 mm width define the tapered seat the bearing is driven onto 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 3172 nut on the Tr 360x5 thread advances 5 mm and takes out roughly 0.417 mm of clearance at 340 mm the 299 mm-wide seat and its HM 3172 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 340 mm shaft scale — the OH grooves and M 6 connection are what make the 299 mm taper removable without destroying the seat as part of the oil-injection OH 32 range for 232..K spherical roller bearings, this size keeps series-standard proportions: 299 mm width on a 360 mm bore, so the bearing lands at the catalogue axial position the catalogue row bundles the HM 3172 lock nut and the MS 3172-68 locking clip and references the HMV 72E hydraulic nut for the 360 mm seat typical applications include electric motor and generator shafts, industrial fan and blower impeller shafts and rolling mill and steel plant roll seats 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 rolling mill and steel plant roll 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 3172 nut kit identity for this seat: sleeve OH 3272 H for a 340 mm shaft, 360x460x299 mm taper, Tr 360x5 thread, HM 3172 nut with MS 3172-68 clip, drive-up tool HMV 72E, catalogue mass 60,500 g

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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
• interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
• mounting with the HMV 72E hydraulic nut but without injecting oil first overloads the Tr 360x5 thread and can seize the nut
