48HE-7.5 Bowex Gear Coupling | Elastic Sleeve Coupling

The 48HE-7.5 Bowex Gear Coupling is part of the Bowex curved-tooth gear coupling series engineered for compact, high-performance industrial power transmission. Unlike elastomeric couplings, Bowex gear couplings transmit torque through precision-molded nylon gear sleeves that engage with steel hubs.

The curved-tooth profile allows for angular misalignment while maintaining torsional rigidity and backlash-controlled torque transfer. This makes the 48HE-7.5 configuration well suited for applications requiring accurate shaft positioning, consistent torque transmission, and long service life.

Bowex couplings are widely used in industrial compressor packages, pumps, conveyors, and general motor-driven equipment where dependable performance and low maintenance are critical.

Functional Design and Engineering Advantages

The 48HE-7.5 Bowex coupling utilizes steel hubs with external gear teeth and a precision-molded nylon sleeve that engages both hubs simultaneously. The curved tooth geometry allows:

• Controlled angular misalignment

• Smooth torque transmission

• Reduced edge loading

• Low wear under continuous operation

Because torque is transmitted through gear engagement rather than elastomer compression, Bowex couplings provide high torsional stiffness and accurate shaft positioning.

The nylon sleeve acts as both a torque-transmitting and vibration-mitigating component while eliminating the need for lubrication. This reduces maintenance requirements and simplifies installation.
