Inch-Series Shaft Adapter Sleeve (HE・HA Series)

Specifications

How to choose Adapter sleeves

Points to check when selecting, with the values for this product (Inch-Series Shaft Adapter Sleeve (HE・HA Series)).

1. 1. Select the bore to suit the shaft diameter

   This product: Shaft diameter d1 19.05～80.963 mm

   Select the sleeve bore to match the diameter of the mounting shaft. The listed products cover shaft diameters of 17 to 1060 mm. Metric and inch dimension systems differ, so first confirm the unit of the shaft nominal dimension and select a model number from the same system.

2. 2. Match the bearing bore and taper ratio

   The sleeve outer diameter corresponds to the tapered bore diameter of the bearing, and the listed products range from 25 to 530 mm. Two taper ratios are available, 1:12 and 1:30, and common bearings use 1:12. Correct contact requires the same taper ratio as the bearing tapered bore, so check against the bearing model number.

3. 3. Check the thread designation of the nut

   This product: Thread G M 25x1,5～M 90x2

   The thread designation of the lock nut used for tightening determines the compatibility of the nut and hydraulic nut. Thread standards may change between large and small sizes, so check the thread standard column for bores below 200 mm and for bores of 200 mm and above separately.

4. 4. Check shaft tolerance and cylindricity

   Adapter sleeves can be used on shafts without precision fit machining, so a relatively wide shaft tolerance is recommended on the shaft side. Poor cylindricity, however, causes uneven clamping and non-uniform internal clearance and fixing force in the bearing. Finish the shaft to the recommended shaft tolerance and cylindricity specification.

5. 5. Check dimension standards and accessory configuration

   Interchangeability is determined by the dimensional standard followed, such as ISO or ABMA. Check the model number codes for differences between series, including whether a lock nut and washer are supplied as a set, whether the type is keyless, and whether it is oil-injection compatible.

6. 6. Consider mass and mounting method for large sizes

   The listed products range widely in mass, from 36 to 1012 kg, so lifting equipment is required for large sizes. Large-diameter bearings are difficult to tighten by hand, so select a compatible hydraulic nut for mounting and removal by hydraulic nut or oil-injection method.
