Product Overview: The H 3288 Adapter Sleeve
The H 3288 is a high-quality adapter sleeve designed for mounting bearings with a 440 mm tapered bore onto a 420 mm cylindrical shaft. As a crucial component in our Adapter Sleeves collection and part of the extensive H 3200 Series, this sleeve provides a simple, reliable, and cost-effective method for securing bearings. The assembly, which includes the H 3288 sleeve, a corresponding lock nut, and a lock washer, facilitates easy installation and dismounting without the need for special shaft machining. This feature makes it an ideal solution for a wide range of industrial applications where precision and durability are paramount.
Adapter sleeves work by being pressed into the tapered bore of the bearing. As the lock nut is tightened, the sleeve is drawn into the bearing, creating a secure, interference fit on the shaft. This method ensures that the bearing is perfectly positioned and firmly held, preventing slippage and ensuring optimal performance and longevity. Our H 3288 sleeves are manufactured to meet stringent industry standards, guaranteeing compatibility and performance in demanding operational environments.
Key Features of the H 3288 Adapter Sleeve
- Simplified Mounting: Enables bearings with a tapered bore to be mounted on plain or stepped cylindrical shafts.
- Secure Fit: The tapered design ensures a tight, 360-degree interference fit between the bearing and the shaft when the lock nut is tightened.
- Cost-Effective Solution: Eliminates the need for expensive and precise machining of the shaft, allowing for wider shaft tolerances.
- Complete Assembly: Designed to be used with a lock nut and lock washer (sold separately) for a complete and secure mounting system.
- Easy Dismounting: Simplifies the process of removing the bearing from the shaft for maintenance or replacement.
- High-Quality Material: Constructed from durable steel to withstand high mounting forces and operational stresses, ensuring long service life.
