How the OH-3060-H model number is decoded
the sleeve wall is 30 mm thick at the small end — 10.0% of the 300 mm bore — thin enough to contract evenly onto the 280 mm shaft while keeping the seat round under the clamping load the annular envelope between 300 mm bore and 360 mm OD is about 31,102 mm² in cross section, which sets the 20,500 g mass at steel density for the 168 mm-long slit bush a width-to-bore ratio of 0.56 gives a 168 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 280 mm shaft is purely frictional mass 20,500 g is 68.3 g per mm of bore; the sleeve with its HM 3060 nut and MS 3060 clip forms the complete 168 mm-wide mounting assembly the 20 mm difference between the 280 mm shaft and the 300 mm nominal seat diameter is bridged by taper contraction as the slit sleeve closes during drive-up, rather than by machining the shaft with a 280 mm shaft this is one of the largest metric sleeves listed; the 20,500 g mass and Tr 300x4 trapezoidal thread reflect hardware intended for hydraulic tooling, not hand spanners OH 3060 H is the hydraulic-mounting sleeve for large seats: oil-injection grooves cut drive-up friction sharply, and the HM 3060 nut with MS 3060 clip locks the final position as part of the oil-injection OH 30 range for 230..K spherical roller bearings, this size keeps series-standard proportions: 168 mm width on a 300 mm bore, so the bearing lands at the catalogue axial position the HM 3060 lock nut and the MS 3060 locking clip ship in the kit; controlled drive-up uses the HMV 60E hydraulic nut rather than a spanner typical applications include pump shafts in water and process plants, agricultural machinery axle and PTO shafts and gearbox input and output shafts adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 300 mm bore bearing on a 280 mm shaft in gearbox input and output 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 3060 nut full specification chain for OH 3060 H reads 280 mm shaft / 300 mm seat / 360 mm OD / 168 mm width / Tr 300x4 / HM 3060 nut with MS 3060 clip, drive-up tool HMV 60E / 20,500 g
Typical equipment & failure modes
Common applications
- cement plant kiln and mill trunnion drives
- pump shafts in water and process plants
- food processing line drive shafts
- quarry conveyor head and tail drums
Known failure patterns
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- exceeding the maximum injection pressure for the 300 mm seat can permanently expand the thin sleeve wall
- 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
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- exceeding the maximum injection pressure for the 300 mm seat can permanently expand the thin sleeve wall
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
Frequently asked questions
What shaft size does the OH-3060-H adapter sleeve fit?
the fit is 280 mm shaft to 300 mm bearing bore via the 1:12 taper; OH-3060-H has a 360 mm outside diameter and a 168 mm overall width.
What does the OH 3060 H designation mean?
the letters give the execution and the digits give the bore: OH 3060 H belongs to OH30, fits 300 mm tapered-bore bearings, with oil-injection ducts marked by OH/H.
What is supplied with the OH-3060-H?
You receive the sleeve plus HM 3060 lock nut and MS 3060 locking clip. One nut turn on the Tr 300x4 thread advances 4 mm along the 1:12 taper.
How much does the OH-3060-H adapter sleeve weigh?
20,500 g for the 168 mm-long slit bush — the equivalent of 68.3 g per millimetre of the 300 mm bore.
How is the OH-3060-H mounted on the shaft?
Oil injection plus the HMV 60E: the oil film parts the 300 mm seat while the nut provides controlled force; release pressure and secure the HM 3060/MS 3060 lock at the final position.
