How to choose Adapter sleeves

Points to check when selecting, with the values for this product (Adapter Sleeve).

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

   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

   This product: Taper ratio 1:12 (1:30 for 40 and 41 dimension series)

   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

   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

   This product: Recommended Shaft Tolerance h9

   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

   This product: Dimensional Standard ISO 2982-1

   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.

About Adapter sleeves and all products

Description

A sleeve with a slit along its axial direction. Small sizes are fitted with a nut and locking washer, while large sizes use a nut combined with a fixing clip or fixing plate. Bore diameters of 200 mm and above come standard with oil grooves and ducts. Variants with different suffixes for oil injection use, and modified types for CARB roller bearings and sealed bearings, are also available.

FAQ

Q. Which bearings and shafts can be used with SKF adapter sleeves (OH, OSNW and OSNP series)?

A. They are sleeves for mounting tapered bore bearings on the cylindrical seating surface of a cylindrical or stepped shaft. They can be positioned at any point along the shaft. The recommended shaft tolerance is h9.

Q. What are the dimensional standard, taper ratio and thread standard for SKF adapter sleeves (OH, OSNW and OSNP series)?

A. The dimensional standard is ISO 2982-1. The taper ratio is 1:12, and the 40 and 41 dimension series have a taper ratio of 1:30. The thread standard is metric thread conforming to ISO 965-3 for bore diameters below 200 mm, and metric trapezoidal thread conforming to ISO 2903 for bore diameters of 200 mm and above.

Q. What structural features do SKF adapter sleeves (OH, OSNW and OSNP series) with a bore diameter of 200 mm and above have?

A. Sleeves with a bore diameter of 200 mm and above come standard with oil grooves and ducts. They are compatible with the oil injection method.

Q. Do SKF adapter sleeves (OH, OSNW and OSNP series) use different fixing methods for small and large sizes?

A. Small sizes are fitted with a nut and locking washer, while large sizes use a nut combined with a fixing clip or fixing plate. The lock nut and fixing devices are supplied as a complete set.

Q. Are there modified SKF adapter sleeves (OH, OSNW and OSNP series) that do not interfere with seals or cages?

A. Modified types are available for CARB roller bearings and sealed bearings, and they prevent interference with seals and cages. Models with different suffixes for oil injection use are also available.
