ACT2.3SN Reich Arcusaflex OEM Drive Coupler | Genuine Heavy-Duty Flexible Compressor Coupling

ACT2.3SN Reich Arcusaflex Drive Coupler – Product Overview

The ACT2.3SN Reich Arcusaflex Drive Coupler is a torsionally flexible, high-capacity coupling engineered for heavy-duty rotating machinery. Designed and manufactured by Reich-Kupplungen, the Arcusaflex line is recognized worldwide for its durability and precision. The ACT2.3SN model provides smooth, vibration-free torque transmission while accommodating angular, axial, and radial shaft misalignments.

It is ideally suited for rotary screw compressors, diesel engine drives, and industrial systems where continuous-duty operation and minimal vibration are essential. With its integrated rubber element and robust steel flange hubs, the Arcusaflex design ensures high torque capacity, low maintenance, and excellent damping characteristics across a broad range of speeds.

Key Features and Benefits

• Authentic Reich Arcusaflex OEM Component – Engineered and manufactured in Germany to exact Reich-Kupplungen specifications.

• Torsionally Flexible Design – Absorbs shock loads and dampens torsional vibration to protect connected components.

• High Torque Capacity – Capable of transmitting large rotational forces smoothly and efficiently.

• Advanced Misalignment Compensation – Handles axial, radial, and angular misalignments without loss of torque transmission.

• Long Service Life – Elastomeric element resists oil, heat, and fatigue in continuous operation.

• Maintenance-Free Operation – Lubrication-free coupling allows quick installation and minimal downtime.

Functional Design and Performance

The Reich ACT2.3SN Coupler employs a reinforced rubber element bonded to precision-machined steel flanges. This combination provides the flexibility necessary to isolate vibration and torsional oscillations that commonly occur in high-speed compressor and pump applications.

The elastomer’s damping characteristics are optimized to reduce resonance, allowing smoother startup and steady torque transmission even under fluctuating loads. The coupling’s flexible element also compensates for thermal expansion and slight misalignment, maintaining system balance and extending component lifespan.

Its simple, compact construction and high power density make it a preferred choice for OEM compressor manufacturers and service technicians who require both durability and ease of maintenance.

Applications and Compatibility

The ACT2.3SN Arcusaflex coupling is used in:

• Rotary screw air compressors

• Diesel and electric motor-driven pump systems

• Generators, blowers, and hydraulic power units

• Industrial machinery requiring precise, vibration-controlled torque transfer

This coupling serves as an OEM-specified part for compressors and industrial systems utilizing Reich Arcusaflex designs. Its standardized hub geometry and insert configuration ensure interchangeability across many Arcusaflex coupler sizes and models, making it a trusted choice for both new installations and equipment rebuilds.

Performance Advantages

The Reich ACT2.3SN Arcusaflex Coupler provides unmatched reliability in compressor and pump systems that demand constant operation. Its torsional damping properties protect drive shafts and bearings from shock loads and cyclical stress, while its robust construction ensures years of dependable service.

Compared to non-OEM couplers, the Arcusaflex design maintains critical alignment and vibration isolation across a wider temperature and torque range. The result is reduced mechanical wear, lower maintenance costs, and enhanced compressor performance.

Whether used for OEM replacement or preventative maintenance, the ACT2.3SN delivers OEM-grade precision and consistent long-term performance.
