TAS3073/130_1.4571 SCHAEFER compression-expansion ring

SCHAEFER TAS 3073/130 Stainless Steel Locking Assembly (1.4571)

The SCHAEFER TAS 3073/130_1.4571 is a high-grade mechanical fastener designed for rigid, backlash-free frictional connections on 130 mm shafts. Manufactured from 1.4571 (AISI 316Ti) stainless steel, it offers exceptional resistance to chemical agents, acids, and salt water. The keyless design eliminates shaft stress concentrations, preventing fatigue cracks and allowing for infinite angular positioning of drive components in highly corrosive environments.

Application

• Food Industry: Drive systems in bottling and processing lines subject to aggressive washdown cycles.
• Chemical & Pharmaceutical: Securing mixers and impellers in corrosive media.
• Water & Marine: Drive components for pumps and wastewater treatment facilities exposed to high humidity.
• Industrial Gearboxes: Zero-backlash shaft connections in high-dynamic machinery.
• Outdoor Installations: Mechanisms exposed to direct weather conditions and oxidation.

Technical Specification

• Manufacturer: SCHAEFER (Germany)
• Designation: TAS 3073/130
• Material: 1.4571 (Acid-resistant stainless steel).
• Shaft Diameter (d): 130 mm
• Mechanism: Keyless frictional locking, self-centering.

Note: For stainless steel assemblies, using specialized anti-seize lubricants is highly recommended to ensure uniform clamping pressure and prevent thread galling.

Features and Benefits

• Maximum Chemical Resilience: Titanium-stabilized steel (1.4571) prevents intergranular corrosion.
• Shaft Integrity: Keyless mounting increases shaft fatigue strength and torque capacity.
• High Concentricity: Self-centering geometry minimizes radial run-out, protecting bearings and seals.
• Hygienic Design: Absence of keyways eliminates crevices where contaminants can accumulate.
• Reliable Maintenance: Stainless material prevents component seizure, ensuring easy disassembly even after years of service.

Why Choose This Product

Investing in the SCHAEFER TAS 3073/130 in 1.4571 steel ensures operational continuity in the most demanding sectors. In corrosive settings, standard steel components often seize permanently, leading to destructive removal methods. This stainless SCHAEFER version protects expensive machine shafts and ensures a manageable maintenance process, significantly lowering the Total Cost of Ownership (TCO).
