The Fenaflex Tyre Couplings B (F85) are engineered for robust industrial performance in heavy-duty power transmission applications. Featuring a maximum bore of 70 mm and a minimum bore of 31.75 mm, this coupling includes a set screw on key (M12) that enables firm and easy shaft mounting, eliminating the need for taper lock bushes while ensuring reliable operation.

With critical dimensions of length (L) 154 mm, diameter (D) 103 mm, E dimension 53 mm, and F dimension 53.5 mm, the F85 is built to deliver consistent torque transmission while compensating for angular, parallel, and axial misalignments. The flexible rubber tyre element effectively absorbs shock loads and isolates vibration, reducing mechanical wear and prolonging the service life of connected machinery.

Weighing approximately 14.0 kg, the F85 ‘B’ Flange coupling is ideal for use in demanding environments such as heavy conveyors, industrial mixers, large pumps, and compressors. Its rugged design, vibration-damping capability, and ease of maintenance make it a preferred choice for industries looking for long-lasting and efficient coupling solutions.
