How the OH-3152-H model number is decoded

the OD-to-bore ratio is 1.27: the 330 mm sleeve OD is only 35 mm of section beyond the 260 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 52 T nut on the Tr 260x4 thread advances 4 mm and takes out roughly 0.333 mm of clearance oil reaches the interface through the M 6 duct connection into distribution grooves, so the 21,000 g sleeve can be floated off the 240 mm shaft instead of being pressed or pulled the HM 52 T lock nut carries size index 52 T, matching the bore-code family of the 260 mm seat; the nut engages the Tr 260x4 sleeve thread over its full width for controlled drive-up the catalogue pairs this seat with the HMV 52E hydraulic nut (size 52); at 21,000 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone at 240 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 3152 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 52E nut, then lock with HM 52 T within the oil-injection OH 31 range for 231..K spherical roller bearings this is the 240 mm shaft step; neighbouring steps keep the same hardware concept while the taper seat grows to 260x330 mm here the delivery includes the HM 52 T lock nut and the MB 52 locking clip, and the HMV 52E 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 260 mm bore bearing on a 240 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 52 T nut full specification chain for OH 3152 H reads 240 mm shaft / 260 mm seat / 330 mm OD / 190 mm width / Tr 260x4 / HM 52 T nut with MB 52 clip, drive-up tool HMV 52E / 21,000 g

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
• blocked or contaminated oil ducts fail exactly at peak dismounting pressure; flush and blank the M 6 connection after each use
• 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
