How the OH-3172-H model number is decoded

the sleeve wall is 50 mm thick at the small end — 13.9% of the 360 mm bore — thin enough to contract evenly onto the 340 mm shaft while keeping the seat round under the clamping load the HM 3172 lock nut carries size index 3172, matching the bore-code family of the 360 mm seat; the nut engages the Tr 360x5 sleeve thread over its full width the annular envelope between 360 mm bore and 460 mm OD is about 64,403 mm² in cross section, which sets the 56,000 g mass at steel density for the 259 mm-long slit bush a width-to-bore ratio of 0.72 gives a 259 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 340 mm shaft is purely frictional mass 56,000 g is 155.6 g per mm of bore; the sleeve with its HM 3172 nut and MS 3172-68 clip forms the complete 259 mm-wide mounting assembly with a 340 mm shaft this is one of the largest metric sleeves listed; the 56,000 g mass and Tr 360x5 trapezoidal thread reflect hardware intended for hydraulic tooling, not hand spanners the OH 3172 H number covers the oil-injection bush only; the HM 3172 lock nut, the MS 3172-68 clip and the HMV 72E complete the hydraulic mounting kit listed on the same catalogue row the OH31 designation block places it in the oil-injection OH 31 range for 231..K spherical roller bearings — every sleeve in the block uses the same bore-code logic, and here the 360 mm tapered bore matches the K-suffix bearing it is ordered for the HM 3172 lock nut and the MS 3172-68 locking clip ship in the kit; controlled drive-up uses the HMV 72E hydraulic nut rather than a spanner typical applications include mining crusher and screen exciter shafts, cement plant kiln and mill trunnion drives and electric motor and generator shafts adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 360 mm bore bearing on a 340 mm shaft in electric motor and generator shafts the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the HM 3172 nut ordering digest — OH 3172 H: 340 mm plain shaft to 360 mm tapered bore, sleeve 460 mm OD and 259 mm wide, thread Tr 360x5, supplied with HM 3172 nut with MS 3172-68 clip, drive-up tool HMV 72E; listed mass is 56,000 g

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
• 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
• blocked or contaminated oil ducts fail exactly at peak dismounting pressure; flush and blank the M 6 connection after each use
