How the H-3132 model number is decoded
the M 160x3 thread spans about 39.7 nut turns across the 119 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 160 mm seat mounting and dismounting stay purely mechanical: the KM 32 nut drives the taper home, and backing the nut off releases the 160 mm seat without oil-injection tooling the annular envelope between 160 mm bore and 210 mm OD is about 14,530 mm² in cross section, which sets the 7,250 g mass at steel density for the 119 mm-long slit bush the OD-to-bore ratio is 1.31: the 210 mm sleeve OD is only 25 mm of section beyond the 160 mm seat, leaving room for the bearing outer ring without enlarging the housing bore the KM 32 lock nut carries size index 32, matching the bore-code family of the 160 mm seat; the nut engages the M 160x3 sleeve thread over its full width with a 140 mm shaft this sleeve serves heavy machinery seats; the plain-shaft design saves the considerable machining cost of a stepped shaft at this diameter the un-suffixed H catalogue number means the standard execution; the M 160x3 thread, the KM 32 nut and the MB 32 washer are dimensioned as one matched assembly for this seat the H31 designation block places it in the large-size H 31 range for 231..K spherical roller bearings — every sleeve in the block uses the same bore-code logic, and here the 160 mm tapered bore matches the K-suffix bearing it is ordered for the KM 32 lock nut and the MB 32 locking washer ship in the kit; controlled drive-up uses the HMV 32 E hydraulic nut rather than a spanner typical applications include quarry conveyor head and tail drums, cement plant kiln and mill trunnion drives 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 160 mm bore bearing on a 140 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 KM 32 nut kit identity for this seat: sleeve H 3132 for a 140 mm shaft, 160x210x119 mm taper, M 160x3 thread, KM 32 nut with MB 32 washer, drive-up tool HMV 32 E, catalogue mass 7,250 g
Typical equipment & failure modes
Common applications
- agricultural machinery axle and PTO shafts
- quarry conveyor head and tail drums
- paper machine roll and cylinder journals
- mining crusher and screen exciter shafts
Known failure patterns
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
- hammering the sleeve directly instead of driving through the nut damages the 119 mm slit edge
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected

Frequently asked questions
What shaft size does the H-3132 adapter sleeve fit?
H-3132 (H 3132) mounts on a plain metric shaft of 140 mm and carries a bearing with a 160 mm tapered (K) bore; sleeve OD is 210 mm and width 119 mm.
What does the H 3132 designation mean?
H identifies a standard metric adapter sleeve in the H31 series; the size code encodes the 160 mm tapered bore (bore code × 5 mm).
What is supplied with the H-3132?
The kit contains the KM 32 lock nut and MB 32 locking washer. The HMV 32 E hydraulic nut is the associated mounting tool.
How much does the H-3132 adapter sleeve weigh?
The listed mass is 7,250 g for the sleeve assembly at 160x210x119 mm — about 60.9 g per millimetre of sleeve width.
How is the H-3132 mounted on the shaft?
Lubricate the M 160x3 thread lightly, screw the KM 32 home, then tighten to the catalogue axial displacement while measuring clearance reduction on the 160 mm bearing, and finally bend the MB 32 washer tab.
