Product Overview: The H 3956 Adapter Sleeve
The H 3956 is a high-quality adapter sleeve, a key component within our Adapter Sleeves collection and the robust H 3900 Series. It is expertly designed to facilitate the mounting of bearings with a 280 mm tapered bore onto a 260 mm cylindrical shaft. Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seating as they can be used on plain or stepped shafts. They are easy to install and require no additional location on the shaft.
As a premier supplier of industrial mechanical parts, we ensure our H 3956 sleeves meet stringent industry standards, offering a secure, reliable, and cost-effective solution for a wide range of machinery. This sleeve simplifies the bearing arrangement, making both installation and dismounting straightforward, thereby reducing maintenance time and costs.
Key Features of the H 3956
- Simplified Mounting: Allows for easy installation of tapered bore bearings on cylindrical shafts without the need for shoulders or special machining.
- Secure Fit: The tapered design, combined with a lock nut and lock washer, ensures a tight, friction-locked fit on the shaft, preventing axial movement.
- Precision Machined: Manufactured with high precision to ensure accurate dimensions and reliable performance.
- Durable Construction: Made from high-grade steel for excellent strength and longevity in demanding industrial environments.
- Complete Assembly: Designed to be used with a corresponding lock nut and lock washer (sold separately) to securely clamp the bearing in place.
- Versatile Use: Suitable for use on both plain and stepped shafts, offering flexibility in machine design.
Common Applications
