Product Overview: The HE 212 Adapter Sleeve
The HE 212 is an essential mechanical component from our HE 200 Series, designed for securely mounting bearings with a tapered bore onto cylindrical shafts. Specifically engineered for a 55mm shaft diameter, this adapter sleeve provides a simple and effective method for positioning bearings accurately without the need for shaft shoulders or complex machining. As part of our comprehensive range of Adapter Sleeves, the HE 212 assembly includes a lock nut and lock washer, ensuring a tight and reliable fit that prevents loosening during operation.
This component is crucial for facilitating easy installation and removal of bearings in a wide variety of industrial machines. The split sleeve design allows it to be contracted onto the shaft, creating a firm interference fit that is vital for performance in demanding environments. Trust our high-quality Sleeves and accessories for your mechanical power transmission needs.
Key Features of the HE 212 Adapter Sleeve
