Product Overview: The H 3992 Adapter Sleeve
The H 3992 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 460mm diameter. As a crucial component in our H Series of Adapter Sleeves, it provides a simple, reliable, and cost-effective method for securing bearings, particularly in applications where precision and durability are paramount. This sleeve facilitates easy installation and dismounting, eliminating the need for special shaft machining. The H 3992 is supplied complete with a corresponding lock nut and lock washer, providing a full assembly solution for your machinery.
Part of the robust H 3900 Series, this adapter sleeve ensures a tight and secure fit, enabling the full operational capability of the mounted bearing. Its slitted design allows for strong clamping force when the lock nut is tightened, ensuring the bearing is firmly positioned on the shaft for optimal performance and longevity.
Key Features of the H 3992
