Flange Coupling is a driving coupling between rotating shafts that consists of flanges one of which is fixed at the end of each shaft, the two Flanges being bolted together with a ring of bolts to complete the drive.

A flange coupling meant to bring two tube ends together in a flush, sealed manner. This two-piece coupling unit consists of a keyed receiving side for the flanged end to be fastened to, so it may be married to the opposing tube end, which also has a flanged end. Each flange has either a male or female coupler opening so that when the two ends are brought together, they are aligned without causing resistance or drag in the material being passed through them. This male or female coupling method also creates a stable connection that is resistant to shifting, keeping the flange coupling sturdily in place.

Flange couplings are typically used in pressurized piping systems where two pipe or tubing ends have to come together. The connecting methods for flange couplings are usually very strong because of either the pressure of the material or the sometimes hazardous nature of materials passed through many industrial piping systems. High thread count nut and bolt connections are used to secure the flange couplings in place. These nuts and bolts are usually made from tempered steel or alloys to provide enduring strength and the ability to be tightened to the utmost level to ensure the piping system doesn’t leak at any flanged junction. Most flange couplings utilize four, six, or up to 12 bolt assemblies.


Recommended Product List

Bush Coupling

(1)Coupling is simple in structure, convenient installation, easy replacement, small size, light weight.

(2)If the installation adjustment can keep two relative displacement within the prescribed limits, then coupling will have satisfactory performance and long service life. 

(3) It can be widely applied to all kinds of medium and small power transmission shafts, such as reducer, crane, compressor, conveyor, textile machine, hoist and ball mill, which are not loaded by motors.

(4)The allowable relative displacement of the elastic sleeve pin couplings:
Radial displacement: 0.2~0.6mm angular displacement: 0 ° 30 ‘~1° 30’

Flange Coupling Adapter

Provides a quick means of removing and reinstalling a flanged fitting already in line
Compatible with omni coupling system gaskets to give your inventory more flexibility
One body per nominal pipe size takes the guess work out of deciding which body to choose, just add the correct color flanges and Omni gasket
Coupling end helps relieve stress, absorbs vibration and accepts deflection in the piping s stem
No need for field fabrications, FC ’s work with plain-end pipe to make the flanged connection
Joining plain-end pipe to flanged fittings, meters, valves, or other miscellaneous flanged service equipment

Rigid Flange Coupling

The flange coupling is a rigid coupling and is one of the most widely used fixed rigid couplings. The two half-couplings with
flanges are connected to the two shafts by ordinary flat keys, and then the two half-couplings are bolted together to transmit
motion and torque.
GY type is centered by the reaming bolts, and the assembly and disassembly does not move in the axial direction.
GYS type concave and convex groove is centered, easy to process, but the assembly and disassembly should move in the axial

Active end: Y-axis hole, A-type keyway d=45, L=84. Driven end: Y-axis hole, A-type keyway d=45, L=84

Example mark: GYS6-45*84

Flange Flexible Coupling

Flange Couplings transmit power smoothly, and these couplings can absorb shock load and vibration.

Flange Couplings do not require lubrication and are virtually maintenance free. The simplified form of this piece enables a quick and easy installation. These couplings are easy and low cost to assemble and disassemble.

The Flange Flexible Couplings can safely operate without any hard covers.

Flexible Motor Coupling

This flexible type motor coupling can connect your driving shaft with the driven shaft while it is very efficient in eliminating any misalignment to the possible extent. Minimum backlash is another great advantage of this Aluminium Flexible Coupling Coupler Helical Shaft 5mm x 8mm. This Flexible coupling with the outer diameter of 19mm and the length of 25mm is machined aluminum coupling. First bore diameter is 5mm and the second bore diameter is of 8mm also. It comes with the spiral cut in the middle along its length which makes it flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects.
