How the H-3034-E model number is decoded
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 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 33.7 nut turns across the 101 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 170 mm seat 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 for controlled drive-up the catalogue pairs this seat with the HMV 34 E hydraulic nut (size 34); at 5,900 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone at 150 mm shaft this is a large sleeve — the 5,900 g mass and long taper seat mean mounting uses a hydraulic nut plus feeler-gauge measurement, not torque alone reading H 3034 E: the trailing E means the sleeve ships with a KMFE 34 lock nut whose built-in locking element replaces the MB washer, cutting one part from the bill of materials the H30 designation block places it in the large-size H 30 range for 230..K spherical roller bearings — every sleeve in the block uses the same bore-code logic, and here the 170 mm tapered bore matches the K-suffix bearing it is ordered for hardware on this row: the KMFE 34 lock nut; SKF lists the HMV 34 E hydraulic nut for mounting and dismounting typical applications include textile machine roller shafts, marine winch and deck machinery shafts and woodworking saw and planer spindles 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 woodworking saw and planer spindles 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 3034 E reads 150 mm shaft / 170 mm seat / 220 mm OD / 101 mm width / M 170x3 / KMFE 34 self-locking nut, drive-up tool HMV 34 E / 5,900 g
Typical equipment & failure modes
Common applications
- gearbox input and output shafts
- textile machine roller shafts
- agricultural machinery axle and PTO shafts
- paper machine roll and cylinder journals
Known failure patterns
- 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
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
- the KMFE 34 self-locking nut must not be replaced with a standard KM nut, which has no integral device to grip the thread
- 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
Selection pitfalls — read before you substitute
- 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
- reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
- 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
Frequently asked questions
What shaft size does the H-3034-E adapter sleeve fit?
the fit is 150 mm shaft to 170 mm bearing bore via the 1:12 taper; H-3034-E has a 220 mm outside diameter and a 101 mm overall width.
What does the H 3034 E designation mean?
the letters give the execution and the digits give the bore: H 3034 E belongs to H30, fits 170 mm tapered-bore bearings, and the E marks the KMFE self-locking nut execution.
What is supplied with the H-3034-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-3034-E adapter sleeve weigh?
5,900 g for the 101 mm-long slit bush — the equivalent of 34.7 g per millimetre of the 170 mm bore.
How is the H-3034-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.
