Adapter sleeves are used for securing tapered bore bearings on to the cylindrical shafts, it easy mounting and dismounting

1. Adapter sleeves are used for securing tapered bore bearings on to the cylindrical shafts. They facilitate easy mounting and dismounting. They are suitable for both smooth and stepped shafts. The sleeves can easily adapt to the shaft diameter.

2. The adapter sleeves have slotted design and an external taper. They are usually not surface treated but oiled and are supplied with a lock nut and a locking device. They have an oil duct, distribution groove, and a threaded side. For stepped shafts, they have two supply ducts and distribution grooves on the outer surface.

3. Withdrawal sleeves are used for mounting tapered bearings on to the cylindrical shafts. They facilitate easy mounting, securing and dismounting. They are suitable for both smooth and stepped shafts. Bearing sleeve can easily adapt to the shaft diameter. They are usually coated with a preservative, are slotted and have an external taper. This allows the sleeve to be used with wide spherical roller bearings. Withdrawal sleeves for oil injection have oil ducts and distribution grooves, on the threaded side.

4. We supply the Adapter Sleeves in accordance with ISO H3/1-1979, both Metric and Inch.

The standard assortment of adapter sleeves includes (product tables):

metric adapter sleeves

with a metric bore

with an inch bore

inch adapter sleeves

For larger sizes (bore diameter, d1 ≥ 1 060 mm) and variants not listed, contact us.

The sleeves are slit and are supplied complete with a lock nut and locking device:

Smaller sizes have a nut and a lock washer.

Larger sizes have a nut and a locking clip or locking plate.

Metric sleeves:

with a bore diameter ≤ 180 mm (size ≤ 40) are phosphated

with a bore diameter > 180 mm are coated with a solventless rust inhibitor

Inch sleeves are coated with a solventless rust inhibitor.

	Metric series	Inch series
Dimension standards	ISO 2982-1, except for the bore diameter of sleeves for inch shafts	ANSI/ABMA Std. 8.2
Tolerances	Bore diameter: JS9 Width: h15
External taper	1:12 as standard 1:30 as standard in the 40 and 41 dimension series
Thread	Bore diameter < 200 mm (size ≤ 40): metric thread in accordance with ISO 965-3, matching the included SKF lock nut Bore diameter ≥ 200 mm (size ≥ 44): metric trapezoidal thread in accordance with ISO 2903, matching the included SKF lock nut	Bore diameter ≤ 12 in. (size ≤ 64): Unified Special Form ANSI/ASME B1.1 Bore diameter ≥ 12 7/16 in. (size ≥ 68): ACME thread class 3G
Shaft tolerances	h9Ⓔ Total radial run-out: IT5/2 – ISO 1101 Adapter sleeves adjust to the shaft diameter so that wider diameter tolerances can be permitted compared to the seat of a bearing with a cylindrical bore. However, the geometrical tolerances must be kept within narrow limits as they directly affect the shaft positioning and vibration.
