How the OH-3160-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 3160 nut on the Tr 300x4 thread advances 4 mm and takes out roughly 0.333 mm of clearance this sleeve mounts a bearing with a 300 mm tapered bore onto a plain 280 mm shaft; the 380 mm outside diameter and 208 mm width define the tapered seat the bearing is driven onto the sleeve wall is 40 mm thick at the small end — 13.3% of the 300 mm bore — thin enough to contract evenly onto the 280 mm shaft while keeping the seat round under the clamping load a width-to-bore ratio of 0.69 gives a 208 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 280 mm shaft is purely frictional mass 29,000 g is 96.7 g per mm of bore; the sleeve with its HM 3160 nut and MS 3160 clip forms the complete 208 mm-wide mounting assembly the 280 mm shaft size is the domain of rolling-mill, paper-machine and marine equipment — the oil ducts and the HMV 60E hydraulic nut are essential at this scale OH marks the dismountable execution for the 300 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 31 range for 231..K spherical roller bearings; the 380 mm OD and 208 mm width follow the ISO 2982-1 boundary plan for that series hardware on this row: the HM 3160 lock nut and the MS 3160 locking clip; SKF lists the HMV 60E hydraulic nut for mounting and dismounting typical applications include food processing line drive shafts, electric motor and generator shafts and quarry conveyor head and tail drums adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 300 mm bore bearing on a 280 mm shaft in quarry conveyor head and tail drums the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the HM 3160 nut ordering digest — OH 3160 H: 280 mm plain shaft to 300 mm tapered bore, sleeve 380 mm OD and 208 mm wide, thread Tr 300x4, supplied with HM 3160 nut with MS 3160 clip, drive-up tool HMV 60E; listed mass is 29,000 g

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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 60E hydraulic nut but without injecting oil first overloads the Tr 300x4 thread and can seize the nut
• over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
