Product Overview: The HE 209 Adapter Sleeve
The HE 209 is a high-quality adapter sleeve designed to securely mount bearings with a 45 mm tapered bore onto a 40 mm cylindrical shaft. As a key component in our HE 200 Series, this sleeve is an essential part of our comprehensive Adapter Sleeves collection. It provides a simple, reliable, and cost-effective method for locating bearings, eliminating the need for complex and expensive stepped shafts. The assembly is secured using a corresponding KM 09 lock nut and MB 09 lock washer, ensuring a tight fit and preventing axial movement during operation.
Manufactured from durable materials, the HE 209 is designed for longevity in demanding industrial environments. Its split-sleeve design facilitates straightforward installation and dismounting, significantly reducing maintenance time and effort. This makes it an ideal choice for a wide variety of machinery where precise and secure bearing mounting is critical.
