Product Description

Shaft Locking Device/Keyless Locking Assembly

Shaft Locking Device (also known as a Keyless Locking Assembly) is a precision mechanical element designed to create a high-strength, keyless connection between a shaft and a hub using tapered expansion principles. By tightening the screws, the inner and outer tapered rings generate radial pressure and axial clamping force, producing a high-friction connection capable of transmitting very large torques.

This design eliminates the need for keyways, preserves shaft strength, and provides excellent concentricity, high load capacity, and easy installation and removal. It is widely used in modern power transmission systems requiring reliable and maintenance-friendly shaft connections.

Materials & Surface Treatment
Materials: Alloy Steel (42CrMo4 / 4140), Carbon Steel (C45 / 1045),Stainless Steel(304/316)
Surface Treatments: Black oxide, phosphating, zinc plating, or anti-rust protection

Features
1.Keyless connection without weakening the shaft
Eliminates keyways and avoids stress concentration.
2.Excellent concentricity and positioning accuracy
Self-centering taper design ensures precise hub-to-shaft alignment.
3.Very high torque transmission capacity
Frictional connection suitable for heavy loads and shock conditions.
4.Simple installation and disassembly
Assembly completed by tightening or loosening screws only.
5.Allows axial and angular adjustment
Facilitates precise positioning during installation.
6.Prevents fretting corrosion
Tight contact eliminates micro-movement between shaft and hub.
7.Standardized and interchangeable
Can replace equivalent products from Ringfeder, KTR, Tollok, Fenner and other similar brands.

Applications

Pulleys, sprockets, timing pulleys, and gears
Couplings and brake discs
Conveying and material handling systems
Fans, pumps, crushers, and ball mills
Mining, cement, and metallurgical heavy equipment
Automation and precision machinery systems
