Polyurethane Round Belt

TransDrive Polyurethane (PU) Round Belts, also known as “O” Belts or Connected Round Belts, have become the modern alternative to traditional materials such as fibreglass insulation, timber, and rubber. Engineered for durability and versatility, these belts deliver high tensile strength, excellent wear resistance, and outstanding flexibility.

Resistant to chemicals, oils, and moisture, TransDrive PU Round Belts provide reliable performance across a wide operating temperature range. They are available in multiple configurations, including smooth (orange, glossy), rough (dark green, textured), transparent (clear or tinted), and reinforced cord options for higher tensile strength.

Well suited to a broad range of industries, these belts are ideal for packaging, printing, textiles, food processing, ceramics, woodworking, pharmaceuticals, glass manufacturing, as well as conveying and automated machinery applications.
