SKF H 2308, a metric adapter sleeve assembly for mounting a tapered-bore bearing onto a plain cylindrical shaft. Shaft Seat Diameter: 35 mm. Tapered Outside Diameter: 40 mm. Taper: 1:12. Overall Width: 46 mm. Thread: M40x1.5. Locknut: SKF KM 8. Lockwasher: SKF MB 8. Locknut Outside Diameter: 58 mm. Material: carbon steel. GTIN: 7316577008640. Country of origin as marked: Sweden.
H — adapter sleeve, the slotted tapered sleeve that grips a plain shaft when the bearing is driven up its taper.
23 — the sleeve family for 2300, 22300 and 23200 series bearings, which fixes the 40 mm tapered seat.
08 — the size code, giving a 35 mm cylindrical shaft seat under a 40 mm tapered outside diameter.
The sleeve’s tapered outside diameter is 40 mm, so it carries any bearing with a 40 mm 1:12 tapered bore — the 2308 K self-aligning ball, 22308 K and 23208 K spherical rollers, and the 1308 K self-aligning ball all seat on it. The shaft under the sleeve is a plain 35 mm cylindrical seat with no shoulder machining and no interference fit required, which is why adapter-sleeve mounting is standard on long line shafts and drawn bar stock. Driving the bearing up the 1:12 taper expands the inner ring and sets radial internal clearance by measured drive-up, so clearance reduction is controlled at assembly rather than fixed by shaft tolerance.
Shaft Seat Diameter: 35 mm, cylindrical. Tapered Outside Diameter: 40 mm, 1:12 taper. Overall Width: 46 mm. Thread: M40x1.5, which is the KM 8 locknut thread. The MB 8 lockwasher inner tab drops into the sleeve keyway and an outer tab folds into a locknut slot to hold the setting.
Unit Quantity: 1 Set. One assembly comprises the H 2308 sleeve, the KM 8 locknut and the MB 8 lockwasher.
Manufacturer part number variants: H 2308, H2308, H-2308. The assembly is dimensionally interchangeable with any maker’s H 2308 adapter sleeve on the same DIN 5415 taper, and the KM 8 nut and MB 8 washer are separately standard parts to the same thread and keyway. Sleeve selection follows the bearing bore: a 40 mm tapered bore takes this sleeve, a 45 mm tapered bore takes an H 2309.
