How the H-3030-E model number is decoded
mounting and dismounting stay purely mechanical: the KMFE 30 nut drives the taper home, and backing the nut off releases the 150 mm seat without oil-injection tooling the seat taper is 1:12, so each millimetre of axial drive-up removes about 1/12 mm of radial clearance; one turn of the KMFE 30 nut on the M 150x2 thread advances 2 mm and takes out roughly 0.167 mm of clearance the M 150x2 thread spans about 43.5 nut turns across the 87 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 150 mm seat the KMFE 30 lock nut carries size index 30, matching the bore-code family of the 150 mm seat; the nut engages the M 150x2 sleeve thread over its full width for controlled drive-up the catalogue pairs this seat with the HMV 30 E hydraulic nut (size 30); at 3,750 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone at 135 mm shaft this is a large sleeve — the 3,750 g mass and long taper seat mean mounting uses a hydraulic nut plus feeler-gauge measurement, not torque alone the E variant simplifies the parts list for the 135 mm shaft: one KMFE 30 nut replaces nut plus washer, which also removes the risk of a forgotten or wrongly seated MB washer dimensionally this sleeve belongs to the large-size H 30 range for 230..K spherical roller bearings; the 195 mm OD and 87 mm width follow the ISO 2982-1 boundary plan for that series hardware on this row: the KMFE 30 lock nut; SKF lists the HMV 30 E hydraulic nut for mounting and dismounting typical applications include food processing line drive shafts, electric motor and generator shafts and quarry conveyor head and tail drums adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 150 mm bore bearing on a 135 mm shaft in quarry conveyor head and tail drums the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KMFE 30 nut ordering digest — H 3030 E: 135 mm plain shaft to 150 mm tapered bore, sleeve 195 mm OD and 87 mm wide, thread M 150x2, supplied with KMFE 30 self-locking nut, drive-up tool HMV 30 E; listed mass is 3,750 g
Typical equipment & failure modes
Common applications
- printing press cylinder journals
- food processing line drive shafts
- conveyor pulley and drum bearing seats
- industrial fan and blower impeller shafts
Known failure patterns
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- 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
- the integral locking screw must be set to the catalogue torque; over-setting galls the M 150x2 thread and makes removal difficult
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
- misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
Selection pitfalls — read before you substitute
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- the integral locking screw must be set to the catalogue torque; over-setting galls the M 150x2 thread and makes removal difficult
- 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-3030-E adapter sleeve fit?
H 3030 E is listed for a 135 mm plain shaft; its tapered bore accepts 150 mm K-suffix bearings, the sleeve measures 195 mm OD and 87 mm wide.
What does the H 3030 E designation mean?
H 3030 E: H-series metric adapter sleeve in the H30 dimension plan; the code resolves to a 150 mm tapered bore and a 135 mm shaft.
What is supplied with the H-3030-E?
Supplied hardware is the KMFE 30 lock nut. Drive-up is done with the HMV 30 E hydraulic nut.
How much does the H-3030-E adapter sleeve weigh?
It weighs 3,750 g; the figure is the sleeve-only catalogue mass, with the KMFE 30 nut counted on the same product row but the hydraulic tool ordered separately.
How is the H-3030-E mounted on the shaft?
Slide the sleeve onto the 135 mm plain shaft against the abutment, fit the bearing, turn the KMFE 30 nut with a hook spanner until the measured clearance drop matches the table, and lock it via its integral screw.
