Product Overview: The H 31/710 Adapter Sleeve
The H 31/710 is a high-strength adapter sleeve designed for mounting bearings with a 710 mm tapered bore onto a 700 mm cylindrical shaft. As a critical component in our Adapter Sleeves collection and a part of the H 3100 Series, this sleeve provides a simple, reliable, and cost-effective method for securing large bearings. The assembly, which includes a precision-engineered sleeve, a corresponding lock nut, and a lock washer, ensures a tight and secure fit, facilitating easy installation and removal without the need for specialized shaft machining.
Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical shaft seat. They can be used on plain shafts, which require no additional location features, or on stepped shafts. The H 31/710 is ideal for heavy-duty industrial applications where robust and dependable performance is essential. Explore our full range of Sleeves to find the perfect solution for your machinery needs.
Key Features of the H 31/710 Adapter Sleeve
- Complete Mounting Solution: Supplied as a complete set with a lock nut and lock washer for secure and reliable fastening.
- Simplified Installation: Enables easy mounting of tapered bore bearings on cylindrical shafts, reducing assembly time.
- Versatile Shaft Compatibility: Can be used on both plain and stepped shafts, offering flexibility in machine design.
