How the H-314-E model number is decoded
a width-to-bore ratio of 0.74 gives a 52 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 60 mm shaft is purely frictional the sleeve wall is 11 mm thick at the small end — 15.7% of the 70 mm bore — thin enough to contract evenly onto the 60 mm shaft while keeping the seat round under the clamping load mass 670 g is 9.6 g per mm of bore; the sleeve with its KMFE 14 nut forms the complete 52 mm-wide mounting assembly the 10 mm difference between the 60 mm shaft and the 70 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 70x2 thread spans about 26.0 nut turns across the 52 mm width; each indexed turn is a measurable drive-up step when setting the bearing clearance on the 70 mm seat the 60 mm size is the volume tier of the range; the KMFE 14 nut and its locking element suit routine field replacement without special tooling H 314 E keeps the same 70x92x52 mm sleeve geometry as the plain H size; only the locking concept changes to the integrated device inside the KMFE 14 nut as part of 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, this size keeps series-standard proportions: 52 mm width on a 70 mm bore, so the bearing lands at the catalogue axial position the catalogue row bundles the KMFE 14 lock nut and references the HMV 14 E hydraulic nut for the 70 mm seat typical applications include printing press cylinder journals, textile machine roller shafts and conveyor pulley and drum bearing seats adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 70 mm bore bearing on a 60 mm shaft in conveyor pulley and drum bearing seats the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KMFE 14 nut kit identity for this seat: sleeve H 314 E for a 60 mm shaft, 70x92x52 mm taper, M 70x2 thread, KMFE 14 self-locking nut, drive-up tool HMV 14 E, catalogue mass 670 g
Typical equipment & failure modes
Common applications
- industrial fan and blower impeller shafts
- printing press cylinder journals
- pump shafts in water and process plants
- gearbox input and output shafts
Known failure patterns
- neglecting the catalogue axial displacement value leaves the bearing either loose on the taper or preloaded hot in service
- 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
- 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
- the integral locking screw must be set to the catalogue torque; over-setting galls the M 70x2 thread and makes removal difficult

Frequently asked questions
What shaft size does the H-314-E adapter sleeve fit?
H-314-E (H 314 E) mounts on a plain metric shaft of 60 mm and carries a bearing with a 70 mm tapered (K) bore; sleeve OD is 92 mm and width 52 mm.
What does the H 314 E designation mean?
H identifies a standard metric adapter sleeve in the H3 series; the size code encodes the 70 mm tapered bore (bore code × 5 mm). The E suffix means a KMFE lock nut with integral locking device is supplied.
What is supplied with the H-314-E?
The kit contains the KMFE 14 lock nut. The HMV 14 E hydraulic nut is the associated mounting tool.
How much does the H-314-E adapter sleeve weigh?
The listed mass is 670 g for the sleeve assembly at 70x92x52 mm — about 12.9 g per millimetre of sleeve width.
How is the H-314-E mounted on the shaft?
Lubricate the M 70x2 thread lightly, screw the KMFE 14 home, then tighten to the catalogue axial displacement while measuring clearance reduction on the 70 mm bearing, and finally bend set the integral locking screw.
