Bellows
Centryco Bellows are available in a wide variety of construction, sizes, and fabrics to accommodate your application. Our Sewn construction (BS) is utilized for our general-purpose bellows to protect moving rods, shafts, screws, or other linear mechanisms from dust to weld spatter.
Our Molded (BM) or RF Welded (BW) Bellows are available for watertight, aesthetics, strict compression, and other specialty applications.
Sewn Bellows
Sewn bellows are made from a series of stamped annular rings which are sewn together to form the individual convolutions. Special “split” bellows are available with a zipper closure to eliminate machine disassembly and downtime. Sewn Bellows are offered in a variety of materials and material thickness’ with superior abrasive resistance to accommodate various applications including protection from most industrial contaminants, high-temperature, and welding sparks to name a few.
Molded Bellows
Molded Polyurethane Bellows (Black) are available in stock sizes (1 or 2 foot lengths) or non-standard sizes.
- Excellent resistance to abrasion
- Temperature range from -60 to +225F
- Flaccid with minimum resistance to movement
- Long Life
- Very good mechanical strength
- Inhibits vibration transmission
- Ideal for ultra light motor applications
- Allows for minor misalignment without deformation
- Good chemical resistance to Ozone, Hydrocarbons, moderate chemicals, UV rays, oils, fuels, and greases
- Excellent for a broad range of interior and exterior applications
RF Welded Bellows
New Radio Frequency (RF) Welded Bellows offer many of the same advantages as our molded bellows and are ideal for a broad range of applications.
- Individually welded pieces of black polyurethane film
- Outstanding Extension to Compression ratios (ideal for applications with limited space)
- Provide leak-tight seal
- Excellent resistance to abrasion
- Temperature range from -60 to +225F
- Flaccid with minimum resistance to movement
- Long Life
- Very good mechanical strength
- Inhibits vibration transmission
- Ideal for ultra light motor applications
- Allows for minor misalignment without deformation
- Good chemical resistance to Ozone, Hydrocarbons, moderate chemicals, UV rays, oils, fuels, and greases
- Excellent for a broad range of interior and exterior applications
