TAS3006/035/060 SCHAEFER compression-expansion ring

SCHAEFER TAS 3006/035/060 Locking Assembly

The SCHAEFER TAS 3006/035/060 is a high-precision mechanical fastener designed to create a rigid, backlash-free frictional connection between a hub and a 35 mm diameter shaft. Based 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 model is characterized by superior self-centering properties, making it ideal for high-precision applications where minimizing run-out and vibration is critical.

Application

• Pulley and Gear Mounting: Precise seating on smooth shafts without the need for milling keyways.
• Industrial Automation: Backlash-free power transmission in systems with high dynamics and frequent reversals.
• Gearboxes and Gear Motors: Connecting output shafts to functional machine elements.
• Rigid Couplings: Building durable shaft-to-shaft connections with high concentricity.
• Drive Retrofitting: Enabling the repair of connections on shafts previously damaged at the keyway site.

Technical Specification

• Manufacturer: SCHAEFER (Germany)
• Designation: TAS 3006/035/060
• Dimensions: 35 mm (ID / d) × 60 mm (OD / D).
• Type: Self-centering Locking Assembly.
• Material: High-strength heat-treated structural steel.

Installation Tip: To achieve rated load capacity, screws must be tightened gradually in a crosswise pattern using a torque wrench, following the Nm values specified by SCHAEFER.

Features and Benefits

• Elimination of Notch Effect: Keyless mounting increases shaft fatigue strength and allows for higher power transmission at the same diameter.
• High Torsional Stiffness: Frictional contact across the entire surface ensures zero rotational play.
• Easy Positioning Adjustment: Allows for infinite angular and axial positioning before final tightening.
• Fretting Corrosion Protection: Solid clamping prevents micro-movements between hub and shaft, preserving mating surfaces.
• Fast Disassembly: Integrated jacking-off threads facilitate easy release during maintenance intervals.

Why Choose This Product

Opting for the SCHAEFER TAS 3006/035/060 locking assembly is an investment in the superior performance of your drive train. Unlike traditional keyed joints, SCHAEFER locking assemblies do not damage the shaft surface and allow for multiple reinstallations. This solution significantly reduces operational costs by eliminating failures caused by loose drive components or fatigue cracks induced by shaft milling.
