Adapter sleeves

Adapter sleeves for mounting bearings with a tapered bore on cylindrical shafts

An adapter sleeve is a key component of bearing accessories, enabling precise and secure seating of bearings with a tapered bore on smooth or stepped cylindrical shafts. In the e-marat.pl product range, you will find a wide selection of sleeves that eliminate the need for additional shaft locating devices, offering the freedom to position the bearing along the machine axis.

Each bearing sleeve available in our store is supplied as a complete mounting kit, which includes:

• Slotted sleeve – with a 1:12 taper, ensuring a perfect fit,
• Locknut – for precise tightening of the component,
• Lock washer – protecting the assembly against loosening during operation.

Technical parameters and applications

The components available from us feature a standard 1:12 taper and are available in both metric and inch versions. Thanks to its slotted design, the bearing adapter sleeve clamps onto the shaft journal, guaranteeing high connection rigidity. This solution is indispensable when mounting spherical roller bearings, self-aligning ball bearings, and modern toroidal roller bearings.

Advantages of using adapter sleeves:

• Can be mounted on a standard, smooth shaft (no need for thread cutting),
• Arbitrary positioning of the bearing along the shaft axis,
• Facilitated replacement of worn components and straightforward dismounting.

Mounting a bearing with an adapter sleeve – choose proven manufacturers

Correct mounting of a bearing with an adapter sleeve involves sliding the component onto the shaft and tightening the locknut, which causes the sleeve to clamp down. For larger bore diameters, we offer models adapted for hydraulic mounting (with oil grooves), which significantly reduces the force required to seat the bearing.

As a professional wholesaler, we deliver solutions exclusively from recognized suppliers. In this category, you will find products from brands such as SCHAEFFLER, SKF, NKE, and ISB. We guarantee the authenticity of our goods and provide full technical support in selecting the right adapter sleeve dimensions for your application.
