How the H-316 model number is decoded

for controlled drive-up the catalogue pairs this seat with the HMV 16 E hydraulic nut (size 16); at 950 g the sleeve and bearing together are too heavy to seat reliably with a hook spanner alone the annular envelope between 80 mm bore and 105 mm OD is about 3,632 mm² in cross section, which sets the 950 g mass at steel density for the 59 mm-long slit bush the sleeve wall is 12.5 mm thick at the small end — 15.6% of the 80 mm bore — thin enough to contract evenly onto the 70 mm shaft while keeping the seat round under the clamping load this sleeve mounts a bearing with a 80 mm tapered bore onto a plain 70 mm shaft; the 105 mm outside diameter and 59 mm width define the tapered seat the bearing is driven onto 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 KM 16 nut on the M 80x2 thread advances 2 mm and takes out roughly 0.167 mm of clearance the 70 mm seat is heavy enough that clearance is set by measured drive-up on the M 80x2 thread, yet light enough that a two-person crew can still mount it conventionally H 316 carries no hydraulic features — the slit sleeve, KM 16 nut and MB 16 washer do all the work mechanically, which keeps the kit simple for the 70 mm shaft size 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: 59 mm width on a 80 mm bore, so the bearing lands at the catalogue axial position the catalogue row bundles the KM 16 lock nut and the MB 16 locking washer and references the HMV 16 E hydraulic nut for the 80 mm seat typical applications include electric motor and generator shafts, paper machine roll and cylinder journals and rolling mill and steel plant roll seats adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 80 mm bore bearing on a 70 mm shaft in rolling mill and steel plant roll seats the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KM 16 nut ordering digest — H 316: 70 mm plain shaft to 80 mm tapered bore, sleeve 105 mm OD and 59 mm wide, thread M 80x2, supplied with KM 16 nut with MB 16 washer, drive-up tool HMV 16 E; listed mass is 950 g

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• a fretted or corroded shaft seat cannot be rescued by a new sleeve — the thin wall conforms to the damage and clamping force collapses
• interchanging nut families (KM vs KMFE, MB vs MS) across executions loses locking reliability even when the thread appears to fit
• misaligning the slit with the load zone or belt-pull direction concentrates stress on the split; orient the slit away from the main load
