How the OH-3264-H model number is decoded

the OD-to-bore ratio is 1.25: the 400 mm sleeve OD is only 40 mm of section beyond the 320 mm seat, leaving room for the bearing outer ring without enlarging the housing bore this sleeve mounts a bearing with a 320 mm tapered bore onto a plain 300 mm shaft; the 400 mm outside diameter and 258 mm width define the tapered seat the bearing is driven onto oil reaches the interface through the M 6 duct connection into distribution grooves, so the 35,000 g sleeve can be floated off the 300 mm shaft instead of being pressed or pulled the HM 3164 lock nut carries size index 3164, matching the bore-code family of the 320 mm seat; the nut engages the Tr 320x5 sleeve thread over its full width for controlled drive-up the catalogue pairs this seat with the HMV 64E hydraulic nut (size 64); at 35,000 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone at 300 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 3264 H mounting is a hydraulic operation: connect the pump to the M 6 duct, inject oil between the mating surfaces, drive home with the HMV 64E nut, then lock with HM 3164 within the oil-injection OH 32 range for 232..K spherical roller bearings this is the 300 mm shaft step; neighbouring steps keep the same hardware concept while the taper seat grows to 320x400 mm here the delivery includes the HM 3164 lock nut and the MS 3164 locking clip, and the HMV 64E 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 320 mm bore bearing on a 300 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 3164 nut kit identity for this seat: sleeve OH 3264 H for a 300 mm shaft, 320x400x258 mm taper, Tr 320x5 thread, HM 3164 nut with MS 3164 clip, drive-up tool HMV 64E, catalogue mass 35,000 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

  • 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
  • interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
  • 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
  • over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
  • mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut

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
  • 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
  • blocked or contaminated oil ducts fail exactly at peak dismounting pressure; flush and blank the M 6 connection after each use

Frequently asked questions

What shaft size does the OH-3264-H adapter sleeve fit?

OH-3264-H (OH 3264 H) mounts on a plain metric shaft of 300 mm and carries a bearing with a 320 mm tapered (K) bore; sleeve OD is 400 mm and width 258 mm.

What does the OH 3264 H designation mean?

OH identifies an oil-injection sleeve with ducts for hydraulic mounting in the OH32 series; the size code encodes the 320 mm tapered bore (bore code × 5 mm). The trailing H marks the hydraulic execution.

What is supplied with the OH-3264-H?

The kit contains the HM 3164 lock nut and MS 3164 locking clip. The HMV 64E hydraulic nut is the associated mounting tool.

How much does the OH-3264-H adapter sleeve weigh?

The listed mass is 35,000 g for the sleeve assembly at 320x400x258 mm — about 135.7 g per millimetre of sleeve width.

How is the OH-3264-H mounted on the shaft?

Inject mounting oil through the M 6 duct, drive the sleeve with the HMV 64E hydraulic nut, measure the axial displacement for the 320 mm seat, then lock with the HM 3164 nut and MS 3164 clip.
