How the OH-3196-H model number is decoded
this sleeve mounts a bearing with a 480 mm tapered bore onto a plain 450 mm shaft; the 620 mm outside diameter and 335 mm width define the tapered seat the bearing is driven onto the OD-to-bore ratio is 1.29: the 620 mm sleeve OD is only 70 mm of section beyond the 480 mm seat, leaving room for the bearing outer ring without enlarging the housing bore 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 3196 nut on the Tr 480x5 thread advances 5 mm and takes out roughly 0.417 mm of clearance the sleeve wall is 70 mm thick at the small end — 14.6% of the 480 mm bore — thin enough to contract evenly onto the 450 mm shaft while keeping the seat round under the clamping load a width-to-bore ratio of 0.70 gives a 335 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 450 mm shaft is purely frictional at 450 mm shaft diameter this sleeve sits in the extra-large band served by oil-injection execution: pressurised oil between the mating surfaces is the only practical way to mount and dismount at this size with OH 3196 H mounting is a hydraulic operation: connect the pump to the M 8 duct, inject oil between the mating surfaces, drive home with the HMV 96E nut, then lock with HM 3196 within the oil-injection OH 31 range for 231..K spherical roller bearings this is the 450 mm shaft step; neighbouring steps keep the same hardware concept while the taper seat grows to 480x620 mm here the delivery includes the HM 3196 lock nut and the MS 3196 locking clip, and the HMV 96E hydraulic nut is the associated drive-up tool typical applications include agricultural machinery axle and PTO shafts, quarry conveyor head and tail drums and paper machine roll and cylinder journals adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 480 mm bore bearing on a 450 mm shaft in paper machine roll and cylinder journals the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the HM 3196 nut full specification chain for OH 3196 H reads 450 mm shaft / 480 mm seat / 620 mm OD / 335 mm width / Tr 480x5 / HM 3196 nut with MS 3196 clip, drive-up tool HMV 96E / 135,000 g
Typical equipment & failure modes
Common applications
- mining crusher and screen exciter shafts
- agricultural machinery axle and PTO shafts
- electric motor and generator shafts
- rolling mill and steel plant roll seats
Known failure patterns
- the shaft must be within h9 tolerance and free of scoring; an oversize or rough shaft stops the slit sleeve closing down and leaves the grip to the thread alone
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- exceeding the maximum injection pressure for the 480 mm seat can permanently expand the thin sleeve wall
- over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
- greasing the tapered seat or shaft destroys the dry friction the joint relies on; a lubricated taper can let the whole sleeve spin under load
Selection pitfalls — read before you substitute
- the shaft must be within h9 tolerance and free of scoring; an oversize or rough shaft stops the slit sleeve closing down and leaves the grip to the thread alone
- exceeding the maximum injection pressure for the 480 mm seat can permanently expand the thin sleeve wall
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
Frequently asked questions
What shaft size does the OH-3196-H adapter sleeve fit?
the fit is 450 mm shaft to 480 mm bearing bore via the 1:12 taper; OH-3196-H has a 620 mm outside diameter and a 335 mm overall width.
What does the OH 3196 H designation mean?
the letters give the execution and the digits give the bore: OH 3196 H belongs to OH31, fits 480 mm tapered-bore bearings, with oil-injection ducts marked by OH/H.
What is supplied with the OH-3196-H?
You receive the sleeve plus HM 3196 lock nut and MS 3196 locking clip. One nut turn on the Tr 480x5 thread advances 5 mm along the 1:12 taper.
How much does the OH-3196-H adapter sleeve weigh?
135,000 g for the 335 mm-long slit bush — the equivalent of 281.3 g per millimetre of the 480 mm bore.
How is the OH-3196-H mounted on the shaft?
Oil injection plus the HMV 96E: the oil film parts the 480 mm seat while the nut provides controlled force; release pressure and secure the HM 3196/MS 3196 lock at the final position.
