48-314.25 Bowex OEM Coupler

The Bowex 48-314.25 OEM Drive Coupler is a curved-jaw coupling from the Bowex product line, used across multiple OEM equipment platforms including portable air compressors, drilling equipment, and industrial machinery. This coupling size is specified in a wide range of equipment from manufacturers including Sullair, Ingersoll Rand, Doosan, and others.

Bowex curved-jaw couplings use an elastomeric spider element between interlocking jaw profiles to transmit torque while providing torsional damping and misalignment compensation. These couplings are valued for their compact design, easy installation, and effective vibration isolation in engine-driven equipment.

When replacing, inspect both jaw halves for wear on the jaw profiles. The spider element should always be replaced during coupling service. Follow the equipment manufacturer’s alignment specifications during installation.

Stark Industrial Products carries Bowex-style couplers for compressor and industrial equipment platforms.
