How the H-313-E model number is decoded
the sleeve wall is 10 mm thick at the small end — 15.4% of the 65 mm bore — thin enough to contract evenly onto the 60 mm shaft while keeping the seat round under the clamping load the KMFE 13 lock nut carries size index 13, matching the bore-code family of the 65 mm seat; the nut engages the M 65x2 sleeve thread over its full width the annular envelope between 65 mm bore and 85 mm OD is about 2,356 mm² in cross section, which sets the 430 g mass at steel density for the 50 mm-long slit bush a width-to-bore ratio of 0.77 gives a 50 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 60 mm shaft is purely frictional mass 430 g is 6.6 g per mm of bore; the sleeve with its KMFE 13 nut forms the complete 50 mm-wide mounting assembly with a 60 mm shaft this sleeve covers the most frequently replaced bearing seats, where using a plain shaft and sleeve avoids the cost of a stepped, ground shaft E on this catalogue number signals self-locking hardware — the KMFE 13 nut is tightened to the seat, then its integral screw is set against the M 65x2 thread as the final step the H3 designation block places it in the medium-section H 3 range, the default seat for 13..K and 22..K self-aligning ball bearings and 222..K spherical roller bearings — every sleeve in the block uses the same bore-code logic, and here the 65 mm tapered bore matches the K-suffix bearing it is ordered for the KMFE 13 lock nut ship in the kit; controlled drive-up uses the HMV 13 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 65 mm bore bearing on a 60 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 KMFE 13 nut ordering digest — H 313 E: 60 mm plain shaft to 65 mm tapered bore, sleeve 85 mm OD and 50 mm wide, thread M 65x2, supplied with KMFE 13 self-locking nut, drive-up tool HMV 13 E; listed mass is 430 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
- 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
- interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- mounting without a fixed abutment lets the bearing walk axially; the sleeve needs a shaft shoulder opposite the lock nut
- a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
Selection pitfalls — read before you substitute
- 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
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- with no washer as a back-up, a slack locking screw is the only way the KMFE 13 nut can unwind — verify it after the first run
Frequently asked questions
What shaft size does the H-313-E adapter sleeve fit?
H 313 E is listed for a 60 mm plain shaft; its tapered bore accepts 65 mm K-suffix bearings, the sleeve measures 85 mm OD and 50 mm wide.
What does the H 313 E designation mean?
H 313 E: H-series metric adapter sleeve in the H3 dimension plan; the code resolves to a 65 mm tapered bore and a 60 mm shaft.
What is supplied with the H-313-E?
Supplied hardware is the KMFE 13 lock nut. Drive-up is done with the HMV 13 E hydraulic nut.
How much does the H-313-E adapter sleeve weigh?
It weighs 430 g; the figure is the sleeve-only catalogue mass, with the KMFE 13 nut counted on the same product row but the hydraulic tool ordered separately.
How is the H-313-E mounted on the shaft?
Slide the sleeve onto the 60 mm plain shaft against the abutment, fit the bearing, turn the KMFE 13 nut with a hook spanner until the measured clearance drop matches the table, and lock it via its integral screw.
