How the H-3134 model number is decoded
mass 8,100 g is 47.6 g per mm of bore; the sleeve with its KM 34 nut and MB 34 washer forms the complete 122 mm-wide mounting assembly the annular envelope between 170 mm bore and 220 mm OD is about 15,315 mm² in cross section, which sets the 8,100 g mass at steel density for the 122 mm-long slit bush the 20 mm difference between the 150 mm shaft and the 170 mm nominal seat diameter is bridged by taper contraction as the slit sleeve closes during drive-up, rather than by machining the shaft the M 170x3 thread spans about 40.7 nut turns across the 122 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 170 mm seat the OD-to-bore ratio is 1.29: the 220 mm sleeve OD is only 25 mm of section beyond the 170 mm seat, leaving room for the bearing outer ring without enlarging the housing bore the 150 mm shaft diameter puts this at the heavy end of the metric range, where the catalogue recommends the HMV 34 E hydraulic nut to reach drive-up without damaging the thread with the H execution the KM 34 lock nut and MB 34 washer are delivered together — the washer is a single-use element that should be renewed whenever the 170 mm seat is remounted within the large-size H 31 range for 231..K spherical roller bearings this is the 150 mm shaft step; neighbouring steps keep the same hardware concept while the taper seat grows to 170x220 mm here the delivery includes the KM 34 lock nut and the MB 34 locking washer, and the HMV 34 E hydraulic nut is the associated drive-up tool typical applications include agricultural machinery axle and PTO shafts, mining crusher and screen exciter shafts and paper machine roll and cylinder journals adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 170 mm bore bearing on a 150 mm shaft in paper machine roll and 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 KM 34 nut ordering digest — H 3134: 150 mm plain shaft to 170 mm tapered bore, sleeve 220 mm OD and 122 mm wide, thread M 170x3, supplied with KM 34 nut with MB 34 washer, drive-up tool HMV 34 E; listed mass is 8,100 g
Typical equipment & failure modes
Common applications
- quarry conveyor head and tail drums
- agricultural machinery axle and PTO shafts
- printing press cylinder journals
- conveyor pulley and drum bearing seats
Known failure patterns
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
- interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
- over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
- 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 H-3134 adapter sleeve fit?
H 3134 is listed for a 150 mm plain shaft; its tapered bore accepts 170 mm K-suffix bearings, the sleeve measures 220 mm OD and 122 mm wide.
What does the H 3134 designation mean?
H 3134: H-series metric adapter sleeve in the H31 dimension plan; the code resolves to a 170 mm tapered bore and a 150 mm shaft.
What is supplied with the H-3134?
Supplied hardware is the KM 34 lock nut and MB 34 locking washer. Drive-up is done with the HMV 34 E hydraulic nut.
How much does the H-3134 adapter sleeve weigh?
It weighs 8,100 g; the figure is the sleeve-only catalogue mass, with the KM 34 nut counted on the same product row but the hydraulic tool ordered separately.
How is the H-3134 mounted on the shaft?
Slide the sleeve onto the 150 mm plain shaft against the abutment, fit the bearing, turn the KM 34 nut with a hook spanner until the measured clearance drop matches the table, and lock it with one MB 34 tab.
