Why Choose Adapter Sleeves

Key Features & Improvements

Engineering advancements that make the Adapter Sleeves the smarter, longer-lasting choice.

  • Complete Assembly: Supplied as a complete set including a tapered sleeve, a lock nut, and a lock washer (or locking clip).
  • Flexible Placement: These sleeves facilitate easy mounting and dismounting as they require no additional location on the shaft; you can mount the bearing at any desired position.
  • Precision Taper: Features a standard external diameter taper of 1:12, designed to match perfectly with the inside tapered bore of the bearing.
  • High-Grade Material: Standard sleeves are manufactured from durable C20 – C30 Carbon Steel and comply with ISO 113/I-1979 dimensions.
  • Hydraulic "OH" Variants: For large-scale applications (Size 44 and above / bore diameter 200 mm+), we offer the "OH" design. These include oil holes and distribution grooves, allowing for hydraulic oil injection to make mounting and dismounting heavy bearings effortless.
