How the H-3134-E model number is decoded
the KMFE 34 lock nut carries size index 34, matching the bore-code family of the 170 mm seat; the nut engages the M 170x3 sleeve thread over its full width the sleeve wall is 25 mm thick at the small end — 14.7% of the 170 mm bore — thin enough to contract evenly onto the 150 mm shaft while keeping the seat round under the clamping load mounting and dismounting stay purely mechanical: the KMFE 34 nut drives the taper home, and backing the nut off releases the 170 mm seat without oil-injection tooling for controlled drive-up the catalogue pairs this seat with the HMV 34 E hydraulic nut (size 34); at 8,100 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone this sleeve mounts a bearing with a 170 mm tapered bore onto a plain 150 mm shaft; the 220 mm outside diameter and 122 mm width define the tapered seat the bearing is driven onto with a 150 mm shaft this sleeve serves heavy machinery seats; the plain-shaft design saves the considerable machining cost of a stepped shaft at this diameter H 3134 E belongs to the E execution: the KMFE 34 nut has an integral grub-screw lock that bears on the sleeve thread, so there is no washer tab to bend and no tab slot to align as part of the large-size H 31 range for 231..K spherical roller bearings, this size keeps series-standard proportions: 122 mm width on a 170 mm bore, so the bearing lands at the catalogue axial position the KMFE 34 lock nut ship in the kit; controlled drive-up uses the HMV 34 E hydraulic nut rather than a spanner typical applications include woodworking saw and planer spindles, cement plant kiln and mill trunnion drives and marine winch and deck machinery shafts 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 marine winch and deck machinery shafts the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KMFE 34 nut full specification chain for H 3134 E reads 150 mm shaft / 170 mm seat / 220 mm OD / 122 mm width / M 170x3 / KMFE 34 self-locking nut, drive-up tool HMV 34 E / 8,100 g
Typical equipment & failure modes
Common applications
- agricultural machinery axle and PTO shafts
- woodworking saw and planer spindles
- paper machine roll and cylinder journals
- mining crusher and screen exciter shafts
Known failure patterns
- the KMFE 34 self-locking nut must not be replaced with a standard KM nut, which has no integral device to grip the thread
- with no washer as a back-up, a slack locking screw is the only way the KMFE 34 nut can unwind — verify it after the first run
- 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
- over-driving the taper eliminates bearing internal clearance entirely; clearance reduction must be measured with feeler gauges, not estimated from nut torque
- greasing the tapered seat or shaft destroys the dry friction the joint relies on; a lubricated taper can let the whole sleeve spin under load

Frequently asked questions
What shaft size does the H-3134-E adapter sleeve fit?
the fit is 150 mm shaft to 170 mm bearing bore via the 1:12 taper; H-3134-E has a 220 mm outside diameter and a 122 mm overall width.
What does the H 3134 E designation mean?
the letters give the execution and the digits give the bore: H 3134 E belongs to H31, fits 170 mm tapered-bore bearings, and the E marks the KMFE self-locking nut execution.
What is supplied with the H-3134-E?
You receive the sleeve plus KMFE 34 lock nut. One nut turn on the M 170x3 thread advances 3 mm along the 1:12 taper.
How much does the H-3134-E adapter sleeve weigh?
8,100 g for the 122 mm-long slit bush — the equivalent of 47.6 g per millimetre of the 170 mm bore.
How is the H-3134-E mounted on the shaft?
Mount dry and clean: drive the bearing up the 1:12 taper by turning KMFE 34 on the M 170x3 thread, using the HMV 34 E hydraulic nut for force, verify clearance with feeler gauges, then apply the nut-integrated lock.
