How the OH-3288-H model number is decoded

the Tr 440x5 thread spans about 72.2 nut turns across the 361 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 440 mm seat the HM 3188 lock nut carries size index 3188, 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 117,000 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone the annular envelope between 440 mm bore and 560 mm OD is about 94,248 mm² in cross section, which sets the 117,000 g mass at steel density for the 361 mm-long slit bush the OD-to-bore ratio is 1.27: the 560 mm sleeve OD is only 60 mm of section beyond the 440 mm seat, leaving room for the bearing outer ring without enlarging the housing bore with a 410 mm shaft this is one of the largest metric sleeves listed; the 117,000 g mass and Tr 440x5 trapezoidal thread reflect hardware intended for hydraulic tooling, not hand spanners the OH 3288 H number covers the oil-injection bush only; the HM 3188 lock nut, the MS 3192-88 clip and the HMV 88E complete the hydraulic mounting kit listed on the same catalogue row the OH32 designation block places it in the oil-injection OH 32 range for 232..K spherical roller bearings — every sleeve in the block uses the same bore-code logic, and here the 440 mm tapered bore matches the K-suffix bearing it is ordered for the HM 3188 lock nut and the MS 3192-88 locking clip ship in the kit; controlled drive-up uses the HMV 88E hydraulic nut rather than a spanner typical applications include quarry conveyor head and tail drums, rolling mill and steel plant roll seats and printing press 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 printing press 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 3188 nut ordering digest — OH 3288 H: 410 mm plain shaft to 440 mm tapered bore, sleeve 560 mm OD and 361 mm wide, thread Tr 440x5, supplied with HM 3188 nut with MS 3192-88 clip, drive-up tool HMV 88E; listed mass is 117,000 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
• neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
• interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
