Product Overview: The H 3268 Adapter Sleeve
The H 3268 is a high-quality adapter sleeve designed for mounting bearings with a 380 mm tapered bore onto a 340 mm cylindrical shaft. As a crucial component in our Adapter Sleeves collection, it provides a simple, reliable, and cost-effective method for securing bearings without the need for a specially machined shaft shoulder or locating feature. Part of the versatile H Series, this sleeve ensures a tight fit and simplifies both the installation and dismounting processes for large-scale machinery.
Our H 3268 adapter sleeve is supplied as a complete assembly, including the corresponding lock nut and lock washer. This ensures that you have all the necessary components for a secure and precise installation. The sleeve's split design and tapered outer surface allow it to be tightened into the bearing bore, creating a powerful interference fit that firmly locks the bearing in position on the shaft. Explore our full range of H 3200 Series sleeves for various shaft sizes.
Key Features of the H 3268 Adapter Sleeve
- Complete Mounting Solution: Supplied with a high-strength lock nut and a secure lock washer for a complete installation package.
- Simplified Installation: Allows for easy mounting of tapered bore bearings onto cylindrical shafts, reducing assembly time and complexity.
