How the OH-3064-H model number is decoded

the Tr 320x5 thread spans about 34.2 nut turns across the 171 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 320 mm seat a width-to-bore ratio of 0.53 gives a 171 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 300 mm shaft is purely frictional the annular envelope between 320 mm bore and 380 mm OD is about 32,987 mm² in cross section, which sets the 22,000 g mass at steel density for the 171 mm-long slit bush the OD-to-bore ratio is 1.19: the 380 mm sleeve OD is only 30 mm of section beyond the 320 mm seat, leaving room for the bearing outer ring without enlarging the housing bore oil reaches the interface through the M 6 duct connection into distribution grooves, so the 22,000 g sleeve can be floated off the 300 mm shaft instead of being pressed or pulled with a 300 mm shaft this is one of the largest metric sleeves listed; the 22,000 g mass and Tr 320x5 trapezoidal thread reflect hardware intended for hydraulic tooling, not hand spanners the OH 3064 H number covers the oil-injection bush only; the HM 3064 lock nut, the MS 3068-64 clip and the HMV 64E complete the hydraulic mounting kit listed on the same catalogue row 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 320 mm tapered bore matches the K-suffix bearing it is ordered for the HM 3064 lock nut and the MS 3068-64 locking clip ship in the kit; controlled drive-up uses the HMV 64E hydraulic nut rather than a spanner typical applications include quarry conveyor head and tail drums, rolling mill and steel plant roll seats and printing press cylinder journals 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 printing press 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 3064 nut kit identity for this seat: sleeve OH 3064 H for a 300 mm shaft, 320x380x171 mm taper, Tr 320x5 thread, HM 3064 nut with MS 3068-64 clip, drive-up tool HMV 64E, catalogue mass 22,000 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
• 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
