How the OH-3088-H model number is decoded
the OD-to-bore ratio is 1.18: the 520 mm sleeve OD is only 40 mm of section beyond the 440 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 3088 nut on the Tr 440x5 thread advances 5 mm and takes out roughly 0.417 mm of clearance oil reaches the interface through the M 8 duct connection into distribution grooves, so the 65,000 g sleeve can be floated off the 410 mm shaft instead of being pressed or pulled the HM 3088 lock nut carries size index 3088, matching the bore-code family of the 440 mm seat; the nut engages the Tr 440x5 sleeve thread over its full width for controlled drive-up the catalogue pairs this seat with the HMV 88E hydraulic nut (size 88); at 65,000 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone at 410 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 3088 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 88E nut, then lock with HM 3088 within the oil-injection OH 30 range for 230..K spherical roller bearings this is the 410 mm shaft step; neighbouring steps keep the same hardware concept while the taper seat grows to 440x520 mm here the delivery includes the HM 3088 lock nut and the MS 3092-88 locking clip, and the HMV 88E hydraulic nut is the associated drive-up tool typical applications include agricultural machinery axle and PTO shafts, pump shafts in water and process plants 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 440 mm bore bearing on a 410 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 3088 nut full specification chain for OH 3088 H reads 410 mm shaft / 440 mm seat / 520 mm OD / 228 mm width / Tr 440x5 / HM 3088 nut with MS 3092-88 clip, drive-up tool HMV 88E / 65,000 g
Typical equipment & failure modes
Common applications
- woodworking saw and planer spindles
- agricultural machinery axle and PTO shafts
- marine winch and deck machinery shafts
- cement plant kiln and mill trunnion drives
Known failure patterns
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
- exceeding the maximum injection pressure for the 440 mm seat can permanently expand the thin sleeve wall
- interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
- 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-3088-H adapter sleeve fit?
the fit is 410 mm shaft to 440 mm bearing bore via the 1:12 taper; OH-3088-H has a 520 mm outside diameter and a 228 mm overall width.
What does the OH 3088 H designation mean?
the letters give the execution and the digits give the bore: OH 3088 H belongs to OH30, fits 440 mm tapered-bore bearings, with oil-injection ducts marked by OH/H.
What is supplied with the OH-3088-H?
You receive the sleeve plus HM 3088 lock nut and MS 3092-88 locking clip. One nut turn on the Tr 440x5 thread advances 5 mm along the 1:12 taper.
How much does the OH-3088-H adapter sleeve weigh?
65,000 g for the 228 mm-long slit bush — the equivalent of 147.7 g per millimetre of the 440 mm bore.
How is the OH-3088-H mounted on the shaft?
Oil injection plus the HMV 88E: the oil film parts the 440 mm seat while the nut provides controlled force; release pressure and secure the HM 3088/MS 3092-88 lock at the final position.
