TB Wood's AP20A350 Spacer Assembly

Description:

The TB Wood's AP20A350 Spacer Assembly is used in industrial power transmission systems to maintain the required distance between coupling hubs while transmitting torque and compensating for shaft misalignment. Commonly installed in pumps, compressors, fans, blowers, conveyors, generators, and other rotating industrial machinery. Maintenance teams, OEMs, and system integrators use this spacer assembly for coupling replacement, drive system maintenance, machinery retrofits, and new power transmission installations.

Applications:

The TB Wood's AP20A350 Spacer Assembly is commonly used in industrial automation environments including pump and compressor drives, conveyor systems, HVAC equipment, power generation systems, mining operations, and manufacturing production lines where precise shaft spacing, reliable torque transmission, and reduced maintenance downtime are essential. Designed for use with TB Wood's Form-Flex® AP Series disc couplings, it provides excellent torsional stiffness while accommodating angular, parallel, and axial shaft misalignment.
