3 mm polyurethane round belt
This green polyurethane round belt has a 3 mm diameter and comes in a 100 ft continuous length. It is designed for power transmission in packaging equipment and similar light-duty machinery. The solid core construction provides consistent performance across the operating range.
Installing the closed loop belt
The belt forms a closed loop, so installation requires threading it over pulleys or temporarily separating a drive component. Ensure the minimum pulley diameter is at least 27 mm to prevent excessive bending stress. The rough surface texture improves grip but may increase wear on soft pulley materials.
Check temperature and chemical compatibility
Verify that the operating environment stays between -22 Degrees F and 150 Degrees F for reliable service. Confirm that the belt's abrasion, chemical and oil resistance meet the specific fluids and contaminants present in your application. The material complies with REACH and RoHS standards for restricted substances.

Questions about this item
How can I verify the 3 mm round belt is seated correctly on a 27 mm pulley after installation?
The green polyurethane belt should sit fully in the pulley groove without twisting. With a rough surface texture and 89A hardness, it will grip firmly when tensioned. Check that the closed-loop belt runs true at operating temperatures between -22 °F and 150 °F.
What comes with the 100 ft roll of Eagle Belting 4905303 and what must I supply?
The box contains a single 100 ft closed-loop round belt, 3 mm diameter, solid-core polyurethane in green. You must provide compatible pulleys with at least 27 mm diameter and any cutting or joining tools if a shorter length is needed.
Which version of this round belt should I choose for a packaging line that sees oil and abrasion?
The 4905303 model is oil-resistant, chemical-resistant and abrasion-resistant, with a rough surface texture for grip. Its polyurethane construction and 89A hardness suit packaging applications, and it meets REACH and RoHS standards.
