TAS130/040/065 SCHAEFER compression-expansion ring

SCHAEFER TAS 130/040/065 Locking Assembly

The SCHAEFER TAS 130/040/065 is a high-precision friction locking device designed to create a rigid, backlash-free connection between a shaft and a hub. Operating on a double-taper principle, tightening the integrated screws generates radial pressure, expanding the ring into the hub and contracting it onto the shaft. This self-centering model is capable of transmitting high torques and axial forces, making it an ideal superior alternative to traditional keyed connections.

Application

• Pulley and Gear Mounting: Precise installation of drive components on smooth shafts without the need for keyways.
• Conveyor Drums: Stable fastening of drive drums in heavy-duty material handling systems.
• Automation and Robotics: Backlash-free power transmission in systems requiring high positioning accuracy.
• Industrial Gearboxes: Connecting output shafts to machine functional elements.
• Machine Retrofitting: Enabling the repair of connections on shafts previously damaged at the keyway site.

Technical Specification

• Manufacturer: SCHAEFER (Germany)
• Designation: TAS 130/040/065
• Main Dimensions: 40 mm (ID / d) × 65 mm (OD / D).
• Type: Internal/External Locking Assembly.
• Material: High-strength heat-treated steel.

Note: During installation, strictly adhere to the screw tightening torques (Nm) specified by the manufacturer to ensure the rated load capacity.

Features and Benefits

• Zero Backlash: The frictional connection eliminates rotational play, protecting the shaft from fretting corrosion and fatigue.
• Easy Adjustment: Allows for infinite angular and axial positioning of the component before final tightening.
• Uniform Stress Distribution: Eliminates the need for keyways, thus removing stress concentrators and increasing shaft fatigue life.
• High Load Capacity: The TAS 130 design is engineered for heavy dynamic loads and reversing drive cycles.
• Efficient Maintenance: Requires only a torque wrench for assembly and disassembly, significantly reducing downtime.

Why Choose This Product

Opting for the SCHAEFER TAS 130/040/065 locking assembly is an investment in the safety and precision of your drive train. Unlike keyed joints, locking assemblies do not damage the shaft structure and allow for multiple reinstallations. This premium solution drastically reduces operating costs by eliminating failures caused by loose components or fatigue cracks in shafts.
