Product Description


The LT elastic bushed pin coupling is a non-metallic elastic element,actually is a kinds of flexible coupling,It’s sturcture very similar to the flange coupling, but the two half couplings are connected with rubber or leather sleeves without bolts.


The structure is relatively simple, easy to manufacture,

No lubrication

No need to vulcanize and bond with metal,

It is convenient to replace the elastic sleeve without moving the half coupling,

It has certain compensation for the relative offset between two axes,the damping and buffering performance.


The elastic sleeve is subject to compression deformation. Due to its thin thickness and small size ,the elastic deformation is limited.Therefore, although the elastic sleeve pin coupling can compensate the axial displacement and elasticity, the allowable compensate ability of axial displacement is less,the elasticity is little bit weak.

bushed pin coupling

Bellow is the parameter of the  FCL Bush Pin Type Flexible Coupling

pin coupling


It is suitable for the transmission of medium and small power pumps with high speed, good rigidity of mounting base, high centering accuracy, low impact load, and low vibration damping requirements.


The elastic sleeve pin coupling was once the most widely used water pump coupling in China. In order to facilitate the replacement of the pin sleeve without moving and disassemble the machine,should be pay attention to the distance in the design; to compensate for axial displacement, should be pay attention to reserve a gap.
