Product Overview: The H 311 Adapter Sleeve
The H 311 Adapter Sleeve is a fundamental component used for mounting bearings with a tapered bore onto a cylindrical shaft, specifically designed for a 50mm shaft diameter. As a key part of our H 300 Series, this sleeve simplifies the installation process, allowing for a secure and precise fit without the need for complex shaft machining. It is an essential part of the wider Adapter Sleeves family, providing a cost-effective and reliable method for locating bearings on smooth or stepped shafts.
The H 311 assembly, which typically includes a corresponding lock nut and lock washer, ensures that the bearing is firmly positioned and prevents loosening during operation. Its split-sleeve design facilitates easy mounting and dismounting, making it an ideal choice for maintenance-heavy applications across various industrial sectors. Trust our high-quality adapter sleeves to provide the stability and performance your machinery requires.
Key Features of the H 311 Sleeve
- Precise Shaft Fit: Designed to mount tapered bore bearings securely onto 50mm cylindrical shafts.
- Simplified Mounting: Eliminates the need for a specially machined shaft shoulder or retaining ring, reducing manufacturing costs.
- Split-Sleeve Design: Features a slot along its length, allowing for easy installation and removal with simple tools.
- Tapered Outer Surface: Matches the tapered bore of the bearing, ensuring a tight interference fit when the lock nut is tightened.
- Complete Assembly Solution: Designed to be used with a KM 11 lock nut and MB 11 lock washer for a secure and reliable hold.
- Durable Construction: Manufactured from high-grade steel to withstand high mounting forces and operational stresses.
