How the OH-3076-H model number is decoded
oil reaches the interface through the M 6 duct connection into distribution grooves, so the 35,500 g sleeve can be floated off the 360 mm shaft instead of being pressed or pulled 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 3076 nut on the Tr 380x5 thread advances 5 mm and takes out roughly 0.417 mm of clearance the OD-to-bore ratio is 1.18: the 450 mm sleeve OD is only 35 mm of section beyond the 380 mm seat, leaving room for the bearing outer ring without enlarging the housing bore the HM 3076 lock nut carries size index 3076, matching the bore-code family of the 380 mm seat; the nut engages the Tr 380x5 sleeve thread over its full width for controlled drive-up the catalogue pairs this seat with the HMV 76E hydraulic nut (size 76); at 35,500 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone the 360 mm shaft size is the domain of rolling-mill, paper-machine and marine equipment — the oil ducts and the HMV 76E hydraulic nut are essential at this scale reading OH 3076 H: OH identifies the oil-injection sleeve — oil is pumped through the M 6 duct connection into interface grooves, so the 35,500 g sleeve floats on and off without pullers or heat the OH30 designation block places it in the oil-injection OH 30 range for 230..K spherical roller bearings — every sleeve in the block uses the same bore-code logic, and here the 380 mm tapered bore matches the K-suffix bearing it is ordered for hardware on this row: the HM 3076 lock nut and the MS 3080-76 locking clip; SKF lists the HMV 76E hydraulic nut for mounting and dismounting typical applications include textile machine roller shafts, electric motor and generator shafts and woodworking saw and planer spindles 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 woodworking saw and planer spindles the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the HM 3076 nut ordering digest — OH 3076 H: 360 mm plain shaft to 380 mm tapered bore, sleeve 450 mm OD and 193 mm wide, thread Tr 380x5, supplied with HM 3076 nut with MS 3080-76 clip, drive-up tool HMV 76E; listed mass is 35,500 g
Typical equipment & failure modes
Common applications
- printing press cylinder journals
- textile machine roller shafts
- conveyor pulley and drum bearing seats
- industrial fan and blower impeller shafts
Known failure patterns
- interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
- 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
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- driving the bearing via the outer ring during mounting loads the rolling elements; force is always applied through the lock nut on the inner ring
- blocked or contaminated oil ducts fail exactly at peak dismounting pressure; flush and blank the M 6 connection after each use
Selection pitfalls — read before you substitute
- interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
Frequently asked questions
What shaft size does the OH-3076-H adapter sleeve fit?
OH 3076 H is listed for a 360 mm plain shaft; its tapered bore accepts 380 mm K-suffix bearings, the sleeve measures 450 mm OD and 193 mm wide.
What does the OH 3076 H designation mean?
OH 3076 H: oil-injection (OH) sleeve with a trailing H for the hydraulic design in the OH30 dimension plan; the code resolves to a 380 mm tapered bore and a 360 mm shaft.
What is supplied with the OH-3076-H?
Supplied hardware is the HM 3076 lock nut and MS 3080-76 locking clip. Drive-up is done with the HMV 76E hydraulic nut.
How much does the OH-3076-H adapter sleeve weigh?
It weighs 35,500 g; the figure is the sleeve-only catalogue mass, with the HM 3076 nut counted on the same product row but the hydraulic tool ordered separately.
How is the OH-3076-H mounted on the shaft?
Connect a high-pressure pump to the M 6 connection, pressurise the 193 mm taper interface, and use the HMV 76E to reach the catalogue drive-up before fitting the HM 3076 lock.
