How the H-319-E model number is decoded

this sleeve mounts a bearing with a 95 mm tapered bore onto a plain 85 mm shaft; the 125 mm outside diameter and 68 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 KMFE 19 nut on the M 95x2 thread advances 2 mm and takes out roughly 0.167 mm of clearance the sleeve wall is 15 mm thick at the small end — 15.8% of the 95 mm bore — thin enough to contract evenly onto the 85 mm shaft while keeping the seat round under the clamping load a width-to-bore ratio of 0.72 gives a 68 mm tapered contact length; the longitudinal slit lets the sleeve close down radially, so the grip on the 85 mm shaft is purely frictional mass 1,450 g is 15.3 g per mm of bore; the sleeve with its KMFE 19 nut forms the complete 68 mm-wide mounting assembly the 85 mm shaft diameter places this in the medium band, where adapter mounting starts to beat press fits because no heating or pressing equipment is needed on site with H 319 E the locking device lives inside the KMFE 19 nut itself: a friction screw engages the M 95x2 thread, so the outer washer and its bent tab disappear from the assembly within 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 is the 85 mm shaft step; neighbouring steps keep the same hardware concept while the taper seat grows to 95x125 mm here the delivery includes the KMFE 19 lock nut, and the HMV 19 E hydraulic nut is the associated drive-up tool typical applications include cement plant kiln and mill trunnion drives, quarry conveyor head and tail drums and food processing line drive shafts adapter sleeves earn their place wherever a tapered-bore bearing must sit at any axial position on a plain shaft — here a 95 mm bore bearing on a 85 mm shaft in food processing line drive shafts the sleeve lets the designer use a plain, unstepped shaft and still locate the bearing positively; only one shoulder is needed, opposite the KMFE 19 nut kit identity for this seat: sleeve H 319 E for a 85 mm shaft, 95x125x68 mm taper, M 95x2 thread, KMFE 19 self-locking nut, drive-up tool HMV 19 E, catalogue mass 1,450 g

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the integral locking screw must be set to the catalogue torque; over-setting galls the M 95x2 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
• reusing a stretched locking washer tab invites fatigue failure; the bent tab snaps off and the nut backs off undetected
