How the OH-3176-H model number is decoded

the HM 3176 lock nut carries size index 3176, matching the bore-code family of the 380 mm seat; the nut engages the Tr 380x5 sleeve thread over its full width the Tr 380x5 thread spans about 52.8 nut turns across the 264 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 380 mm seat a width-to-bore ratio of 0.69 gives a 264 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 360 mm shaft is purely frictional for controlled drive-up the catalogue pairs this seat with the HMV 76E hydraulic nut (size 76); at 61,500 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone this sleeve mounts a bearing with a 380 mm tapered bore onto a plain 360 mm shaft; the 490 mm outside diameter and 264 mm width define the tapered seat the bearing is driven onto with a 360 mm shaft this is one of the largest metric sleeves listed; the 61,500 g mass and Tr 380x5 trapezoidal thread reflect hardware intended for hydraulic tooling, not hand spanners OH 3176 H is the hydraulic-mounting sleeve for large seats: oil-injection grooves cut drive-up friction sharply, and the HM 3176 nut with MS 3176 clip locks the final position as part of the oil-injection OH 31 range for 231..K spherical roller bearings, this size keeps series-standard proportions: 264 mm width on a 380 mm bore, so the bearing lands at the catalogue axial position the HM 3176 lock nut and the MS 3176 locking clip ship in the kit; controlled drive-up uses the HMV 76E hydraulic nut rather than a spanner typical applications include woodworking saw and planer spindles, conveyor pulley and drum bearing seats and marine winch and deck machinery shafts adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 380 mm bore bearing on a 360 mm shaft in marine winch and deck machinery 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 3176 nut kit identity for this seat: sleeve OH 3176 H for a 360 mm shaft, 380x490x264 mm taper, Tr 380x5 thread, HM 3176 nut with MS 3176 clip, drive-up tool HMV 76E, catalogue mass 61,500 g

Typical equipment & failure modes

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
• blocked or contaminated oil ducts fail exactly at peak dismounting pressure; flush and blank the M 6 connection after each use
• over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
