UJK Bearing Tapered Locking Collar and Lock Nut: Product Introduction

UJK Bearing Tapered Locking Collars and Lock Nuts are precision-engineered components designed to provide a secure, reliable, and backlash-free method for mounting bearings onto shafts. This system is essential for applications where a tight, permanent fit is required, and where the shaft diameter does not correspond to a standard bearing bore.

Our locking assemblies consist of two key parts: a precision-ground tapered sleeve (the collar) and a high-strength lock nut. The collar fits over the shaft, and the bearing is mounted onto the collar's outer surface. The lock nut is then tightened, which draws the collar into the bearing's tapered bore. This action creates immense radial pressure, simultaneously locking the collar to the shaft and the bearing to the collar.

Key Features & Benefits:

• Secure Locking Mechanism: The combination of the tapered design and the precision threads ensures a zero-slip, vibration-proof connection, even under high radial loads and variable rotational speeds.

• Simplified Installation & Removal: Eliminates the need for complex machining steps like grinding, honing, or keyways on the shaft. Mounting and dismounting bearings is significantly faster and more cost-effective.

• Exceptional Positional Accuracy: Provides precise axial positioning of the bearing, ensuring optimal alignment and performance within the assembly.

• Shaft Preservation: Protects the shaft surface from scoring and wear, as the locking force is applied by the collar, not directly to the shaft. This allows for easy bearing replacement and maintenance.

• Versatility: An ideal solution for adapting standard bearings to non-standard shaft sizes, offering tremendous design flexibility.

• Robust Construction: Manufactured from high-quality, hardened steels and finished with corrosion-resistant coatings (such as zinc plating) to ensure durability and a long service life in demanding environments.
