How the OH-3164-H model number is decoded
the 20 mm difference between the 300 mm shaft and the 320 mm nominal seat diameter is bridged by taper contraction as the slit sleeve closes during drive-up, rather than by machining the shaft 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 3164 nut on the Tr 320x5 thread advances 5 mm and takes out roughly 0.417 mm of clearance mass 32,000 g is 100.0 g per mm of bore; the sleeve with its HM 3164 nut and MS 3164 clip forms the complete 226 mm-wide mounting assembly the Tr 320x5 thread spans about 45.2 nut turns across the 226 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 320 mm seat the annular envelope between 320 mm bore and 400 mm OD is about 45,239 mm² in cross section, which sets the 32,000 g mass at steel density for the 226 mm-long slit bush the 300 mm shaft size is the domain of rolling-mill, paper-machine and marine equipment — the oil ducts and the HMV 64E hydraulic nut are essential at this scale reading OH 3164 H: OH identifies the oil-injection sleeve — oil is pumped through the M 6 duct connection into interface grooves, so the 32,000 g sleeve floats on and off without pullers or heat 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 320 mm tapered bore matches the K-suffix bearing it is ordered for hardware on this row: the HM 3164 lock nut and the MS 3164 locking clip; SKF lists the HMV 64E hydraulic nut for mounting and dismounting typical applications include industrial fan and blower impeller shafts, gearbox input and output shafts and pump shafts in water and process plants adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 320 mm bore bearing on a 300 mm shaft in pump shafts in water and process plants the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the HM 3164 nut ordering digest — OH 3164 H: 300 mm plain shaft to 320 mm tapered bore, sleeve 400 mm OD and 226 mm wide, thread Tr 320x5, supplied with HM 3164 nut with MS 3164 clip, drive-up tool HMV 64E; listed mass is 32,000 g
Typical equipment & failure modes
Common applications
- marine winch and deck machinery shafts
- industrial fan and blower impeller shafts
- cement plant kiln and mill trunnion drives
- food processing line drive shafts
Known failure patterns
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- 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
- 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
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
Selection pitfalls — read before you substitute
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- 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
- mounting with the HMV 64E hydraulic nut but without injecting oil first overloads the Tr 320x5 thread and can seize the nut
Frequently asked questions
What shaft size does the OH-3164-H adapter sleeve fit?
OH 3164 H is listed for a 300 mm plain shaft; its tapered bore accepts 320 mm K-suffix bearings, the sleeve measures 400 mm OD and 226 mm wide.
What does the OH 3164 H designation mean?
OH 3164 H: oil-injection (OH) sleeve with a trailing H for the hydraulic design in the OH31 dimension plan; the code resolves to a 320 mm tapered bore and a 300 mm shaft.
What is supplied with the OH-3164-H?
Supplied hardware is the HM 3164 lock nut and MS 3164 locking clip. Drive-up is done with the HMV 64E hydraulic nut.
How much does the OH-3164-H adapter sleeve weigh?
It weighs 32,000 g; the figure is the sleeve-only catalogue mass, with the HM 3164 nut counted on the same product row but the hydraulic tool ordered separately.
How is the OH-3164-H mounted on the shaft?
Connect a high-pressure pump to the M 6 connection, pressurise the 226 mm taper interface, and use the HMV 64E to reach the catalogue drive-up before fitting the HM 3164 lock.
