Product Overview: The HE 309 Adapter Sleeve
The HE 309 is a high-quality adapter sleeve designed for securely mounting bearings with a tapered bore onto a 40mm cylindrical shaft. As a crucial component in our Bearing Accessories range, this sleeve simplifies the installation and dismounting process, making it a popular choice in various industrial settings. Part of the HE 300 Series of Adapter Sleeves, the HE 309 assembly includes the tapered sleeve, a corresponding lock nut, and a lock washer, providing a complete and reliable solution for locating bearings on smooth or stepped shafts.
Manufactured to precise standards, this adapter sleeve allows for the use of standard bearings on shafts with wider tolerances, reducing overall machining costs. Its design ensures a tight, concentric fit, which is essential for optimal bearing performance and longevity. Whether for new installations or maintenance, the HE 309 offers a practical and efficient method for bearing mounting.
