Bellows

“Being referred to as industry-main rubber bellow producer in India, PSAP produces bellows towards the patron drawings and specifications.”

PSA Polycraft, situated in Coimbatore, stands as a prominent player in India's rubber manufacturing sector, distinguishing itself as a leading producer of diverse rubber products. Renowned for our excellence, we specialize in manufacturing rubber bellows tailored precisely to customer specifications and drawings, solidifying our position as an industry leader in this domain.

Bellows are expandable or collapsible additives to chorus from overseas particles. The spherical rubber bellows save you the get-away of the lubricant at shaft joints to defend the joints towards soiling.

Bellows are widely used in industrial and mechanical applications such as rod boots, machinery way covers, lift covers and rail covers to protect rods, bearings and seals from dirt.

Types of Bellows


PSA Designing the Bellows Innovation: Presenting the Scope of Precision

1. Single-ended Bellows

  • Precision in Expansion: Ideal for applications where unidirectional expansion is required, providing protection against contaminants and maintaining structural integrity.

  • Where it can be used : Steering Mechanism, Pneumatic Cylinders, Medical Equipment, Flight Control Systems, heating, ventilation, and air conditioning (HVAC) systems, Engine Components, Robotic Arms

2. Double-ended Bellows

  • Balanced Flexibility: Designed for bidirectional expansion, ensuring symmetrical protection and enhanced flexibility in systems requiring movement on both ends.

  • Applications: drive shafts in vehicles, Hydraulic Systems, railway coupling systems, Marine Environments, aerospace landing gear assemblies, Medical Equipment, Spinning Machines

3. Bellows with Ribs & Without Ribs

  • Structural Versatility: Ribs add strength and rigidity, suitable for demanding environments, while rib-free options offer flexibility in less rigid applications

  • Applications: Robust protection, Automated machinery, Agricultural equipment, Material handling systems, construction machinery

4. Telescopic Bellows

  • Adjustable Resilience: Perfect for applications with varying lengths, telescopic bellows smoothly adjust to different extensions, providing reliable protection.

  • Applications: CNC machines and robotic arms, diagnostic and surgical equipment, aircraft landing gear assemblies, material handling equipment, automotive steering systems and suspension components.

5. Tapered Bellows

  • Optimized Flexibility: Tapered design accommodates varying expansion requirements, ensuring a seamless fit and effective protection in tapered or conical systems.

  • Applications: hydraulic cylinders in industrial machinery, Automotive Exhaust Systems, Electrical Cable Protection, mining machinery, medical equipment

6. Convoluted Bellows

  • Flexible Performance: Engineered with convolutions for increased flexibility, making them suitable for intricate movements and tight spaces.

  • Applications: Automotive Suspension Systems, pump and valve components, medical devices with articulated joints, aircraft components such as wing flaps and landing gear, robotic arms and automation equipment

7. Rubber Gaiter Bellows

  • Sealing Excellence: Crafted from high-quality rubber, these bellows provide superior sealing, making them ideal for applications where preventing leaks is paramount.

  • Applications: Integrated into steering column joints, Utilized in pump and valve assemblies, Found in cable management systems, Medical Equipment, robotic arms and machine tools.
