KTR 65 mm OD Steel Stainless Steel Polyamide 12 Carbon Fibre Nylon Polyamide Coupler BOWEXM42-HUB-PB

KTR BOWEXM42-HUB-PB coupler is a flexible mechanical power transmission component designed with a 65 mm outside diameter and constructed using steel, stainless steel, polyamide 12 carbon fibre, nylon, and polyamide for exceptional durability and performance under demanding industrial conditions.

Featuring BoWex curved-tooth gear coupling technology, this product offers double cardanic operation which virtually eliminates wear by avoiding edge pressures in splines and preventing angular and radial displacements. This coupling ensures reliable positive torque transmission and compensates for angular, axial, and radial misalignment with high torsional rigidity.

The combination of steel hubs and polyamide sleeves allows the coupler to operate maintenance-free with reduced friction. Unlike metallic materials that risk corrosion during dry running, the polyamide and steel pairing is lubricative and resistant to common industrial fluids such as lubricants, fuels, hydraulic fluids, and solvents. The operating temperature range includes up to 100° Celsius, accommodating high thermal stability requirements.

Assembly of the coupler is straightforward and tool-free for either vertical or horizontal shaft arrangements. The design supports up to 6000 rpm speed and can transmit torque up to 300 Nm, suitable for a wide variety of machinery in food processing, printing, textile manufacturing, sewage treatment, chemical and pharmaceutical industries, offshore units, and other aggressive environmental applications such as exposure to air, water, and chemicals.

Each coupling hub is supplied unbored to allow custom machining according to application-specific dimensions while maintaining compatibility with the BoWex series coupling sleeve. This product complies with DIN EN ISO 4029, DIN 748/1, DIN 740 part 2, EC directive 94/9/EC (ATEX 95), and ISO 16016 standards, ensuring adherence to international quality and safety requirements.

Designed for flexible shaft connections with positive torque transmission. Handles axial, radial, and angular shaft misalignment efficiently. Maintenance free operation with low friction due to material combination. Maximum operating speed of 6000 rpm with 300 Nm torque rating.

Compatible with various industrial sectors including food, textile, chemical, and offshore applications. Constructed with BoWex curved-tooth gear technology providing torsionally rigid connections. Resistant to corrosion, lubricants, fuels, hydraulic fluids, and solvents.

Can be assembled without special tools in vertical or horizontal orientations.

This coupler is a premium component for industrial, mechanical, and fluid power transmission applications available exclusively on EnvMart in the Mechanical Power Transmission Coupler category.
