Product Overview: H 3128 Adapter Sleeve
The H 3128 is a high-quality adapter sleeve, an essential component from our H 3100 Series of Adapter Sleeves. This sleeve is expertly designed to mount bearings with a 140 mm tapered bore onto a 130 mm cylindrical shaft. It provides a simple, reliable, and cost-effective method for securing bearings, allowing for a tight, concentric fit without the need for complex shaft machining. The H 3128 assembly includes the slotted sleeve, a corresponding lock nut (KM 28), and a lock washer (MB 28), offering a complete solution for robust bearing mounting in a variety of industrial applications.
As a key part of our Bearing Accessories range, this adapter sleeve allows for wider tolerances on the shaft diameter, simplifying both manufacturing and assembly processes. It is widely used with Spherical Roller Bearings and Self-Aligning Ball Bearings on plain or stepped shafts.
