BSTFLEX Sewn Wire Supported Bellows are custom flexible protective covers designed for large-diameter, long-stroke and demanding industrial applications. An internal wire support structure helps maintain the bellows shape during extension and compression, reducing fabric sagging and improving stability during repeated machine movement. These wire reinforced fabric bellows are suitable for protecting hydraulic cylinders, shafts, actuators, telescoping mechanisms and other moving components from dust, metal chips, abrasion, oil, coolant, sparks and heat. Each bellows can be customized in inside diameter, outside diameter, compressed length, extended length, stroke, wire spacing, fabric material and mounting configuration. Coated nylon, silicone coated fiberglass, PTFE coated fiberglass, aluminized fiberglass and other technical fabrics are available for standard or high-temperature applications.

BSTFLEX Sewn Rectangular Bellows are custom flexible protective covers designed for machine ways, linear rails, ball screws, lead screws, actuators and other moving components with square or rectangular profiles. Their accordion-style fabric construction expands and compresses with machine travel while helping protect critical parts from dust, metal chips, abrasion, oil, coolant, sparks and heat. Each rectangular fabric bellows can be customized in width, height, extended length, compressed length, stroke, fold geometry, material and mounting configuration. Available materials include coated nylon, silicone coated fiberglass, PTFE coated fiberglass, aluminized fiberglass and other technical fabrics for standard or high-temperature applications. Custom flanges, mounting plates, reinforced ends, zipper or split designs are available for CNC machines, automation equipment, lifting systems and OEM industrial machinery.

BSTFLEX Sewn Round Bellows are custom flexible protective covers designed for hydraulic cylinder rods, ball screws, lead screws, shafts, actuators and other moving machine components. The pleated fabric construction expands and compresses with equipment movement while helping shield critical parts from dust, metal chips, abrasion, oil, coolant and heat. Each round fabric bellows can be customized in inside diameter, outside diameter, compressed length, extended length, stroke, material and mounting method. Available materials include coated nylon, silicone coated fiberglass, PTFE coated fiberglass, aluminized fiberglass and other technical fabrics for standard or high-temperature applications. Custom collars, flanges, clamps, internal supports and split or zippered designs are available for OEM machinery, replacement parts and special industrial equipment.
