KTR Steel Coupler 44 mm Outside Diameter, 28 mm Bore Diameter, Torque Rating 135Nm BOWEXM28-HUB-PB

KTR BOWEXM28-HUB-PB is a precision-engineered steel flexible coupler used in mechanical power transmission systems. Featuring a 28 mm bore diameter and 44 mm outside diameter, this coupler is designed to transmit torque efficiently with a rating of 135 Nm. It compensates for angular misalignment up to 0.6° and parallel misalignment of 0.23 mm, ensuring reduced wear and extended equipment life.

The BoWex series employs double cardanic curved-tooth gear technology providing virtually wear-free operation due to the avoidance of edge pressure. The unique steel and polyamide sleeve material composition facilitates maintenance-free continuous operation by reducing friction and eliminating the need for lubrication.

Finished with a keyway bore type, the coupler offers secure and accurate shaft connection, suitable for hydraulic pump applications and various industrial machinery.

Its robust steel construction coupled with high thermal stability withstands maximum operating temperatures of 100°C and resists exposure to lubricants, fuels, hydraulic fluids, solvents, and aggressive chemicals.

This coupler is widely used across the food industry, printing and paper, textile manufacturing, sewage treatment, chemical and pharmaceutical sectors, as well as offshore units where reliability and durability are critical.

Constructed from durable steel for high strength and long service life. Bore diameter of 28 mm with an outside diameter of 44 mm for precise fitment. Torque rating of 135 Nm suitable for various mechanical power transmission needs.

Capable of compensating axial, radial, and angular misalignments to reduce wear. Features double cardanic curved-tooth gear design to avoid edge pressure and wear. Finished bore with keyway for secure mounting and efficient torque transfer.

Material combination of steel hubs and polyamide sleeves enables maintenance-free continuous operation. Operates up to a maximum temperature of 100°C with high thermal stability. Resistant to lubricants, fuels, hydraulic fluids, and chemicals, ideal for aggressive environments.

Applicable for heavy industries including food, textiles, chemical, pharmaceutical, and offshore units.

All coupler hubs are supplied unbored and require machining for final fitting according to the specific parameters of the coupling system. Each coupling consists of three parts sold separately: two coupling hubs and one gear coupling sleeve.
