Product Overview: H 31/800 Adapter Sleeve
The H 31/800 is a high-strength adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts. A crucial component in our Adapter Sleeves collection, this sleeve is specifically engineered for a 750mm shaft diameter. It provides a simple, reliable, and cost-effective method for securing large bearings, ensuring a precise and tight fit. Adapter sleeves like the H 31/800 are part of the versatile H 3100 Series and are essential for facilitating bearing installation and removal in heavy-duty industrial applications.
These sleeves come complete with a corresponding lock nut and lock washer, providing a full assembly for secure mounting. The slit design and tapered exterior allow the sleeve to be firmly clamped onto the shaft, creating a solid interference fit when the lock nut is tightened. This method accommodates wider shaft tolerances than direct mounting, simplifying assembly and reducing machining costs. Please note that the '800' in the part number corresponds to the bearing bore size it's designed for (e.g., a 231/800 bearing), while the sleeve itself fits a 750mm shaft.
