How the OH-3184-H model number is decoded

for controlled drive-up the catalogue pairs this seat with the HMV 84E hydraulic nut (size 84); at 80,000 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone the annular envelope between 420 mm bore and 540 mm OD is about 90,478 mm² in cross section, which sets the 80,000 g mass at steel density for the 304 mm-long slit bush the HM 3184 lock nut carries size index 3184, matching the bore-code family of the 420 mm seat; the nut engages the Tr 420x5 sleeve thread over its full width this sleeve mounts a bearing with a 420 mm tapered bore onto a plain 400 mm shaft; the 540 mm outside diameter and 304 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 3184 nut on the Tr 420x5 thread advances 5 mm and takes out roughly 0.417 mm of clearance at 400 mm the 304 mm-wide seat and its HM 3184 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 400 mm shaft scale — the OH grooves and M 6 connection are what make the 304 mm taper removable without destroying the seat as part of the oil-injection OH 31 range for 231..K spherical roller bearings, this size keeps series-standard proportions: 304 mm width on a 420 mm bore, so the bearing lands at the catalogue axial position the catalogue row bundles the HM 3184 lock nut and the MS 3184-80 locking clip and references the HMV 84E hydraulic nut for the 420 mm seat typical applications include electric motor and generator shafts, paper machine roll and cylinder journals 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 420 mm bore bearing on a 400 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 3184 nut ordering digest — OH 3184 H: 400 mm plain shaft to 420 mm tapered bore, sleeve 540 mm OD and 304 mm wide, thread Tr 420x5, supplied with HM 3184 nut with MS 3184-80 clip, drive-up tool HMV 84E; listed mass is 80,000 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
• injection oil of the wrong viscosity either leaks past the thread flanks or stalls the pump before the separating film builds
• mounting with the HMV 84E hydraulic nut but without injecting oil first overloads the Tr 420x5 thread and can seize the nut
