Round Bellows Cover for Ball Screw Shaft & Cylinder Rod

round bellow cover

      Round bellows,shaft bellows 

  • Round bellow cover are popular used for industrial purpose, like protecting shaft, lead screw, air clinder,hydraulic, pneumatic bars, pistons, spindles, linear guides, measureing machines etc, also applied as flexible connections where vibration, movement or misalignment involved.

  • Shaft bellows can be produced without mold cost and are an economical solution for lower quantities. Idea for there have limited space, circular bellows has a good relation between Lmin and Lmax.

  • Round bellow cover protect parts from dust, oil, water, chemical, abrasive, hot metallic shavings, glass dust  high temparature etc.

  • Customized round bellows exactly meet the application needs,  cuff ends, zipper feature for easy installation and future access , various function material to choose from, custom two ends flange for connection purpose.

  Sewn Bellows with copper zipper


  • zipper feature is essential for installation and future access

  • shaft bellows covers feature of oil resistance, water resistance, dustproof and shaving resistance etc

  • Sewn bellows are made of heavy-duty elastomer-coated fabric stitched with nylon or special thread  

  • Sewn seams let these bellows breathe, so they retract quickly in fast-cycling applications.

  Round Bellows with center ring

  • If there has depression inside shaft bellows , then steel rings should be fitted inside the bellow coils for contracting the push of pressure.

  • center ring can prevents rub between bellows and shaft,pistons, spindles, linear guides etc.

  • circular bellows each end for mounting with optional clamps (collars can be replaced with metal & plastic flanges)

cylindrical bellows
