I. Rubber Conveyor Belts
1. Standard Operating Conditions: In heavy-duty scenarios such as mining and ports, high-quality models receiving regular maintenance can achieve a service life of several thousand hours; some specialized heavy-duty models can last 3–5 years under reasonable operating conditions.
2. Influencing Factors: Impact loads and abrasion from sharp materials significantly shorten service life; a 10% overload can cut the lifespan in half.
II. PU (Polyurethane) Conveyor Belts
1. Clean, Light-Load, Ambient-Temperature Scenarios: In stable operating conditions-such as snack food processing or pastry packaging-the service life can reach 1–2 years.
2. High-Frequency, Heavy-Load Scenarios: Under prolonged, continuous high-load operation, the service life is reduced to 6 months–1 year.
3. Comparative Advantages: The overall service life is 2–3 times that of standard rubber belts; thickened models or those with polyester reinforcement layers can extend this lifespan by an additional 40%–60%.
III. PVC Conveyor Belts
1. Standard Dry Operating Conditions: Standard models used in moderate-load scenarios (e.g., electronics, packaging) can achieve a service life of 3–5 years with proper use.
2. Harsh Operating Conditions: In environments involving prolonged exposure to oil or low-temperature embrittlement, the service life may be less than six months; thickened, wear-resistant models can extend this life by over 30%.
IV. Metal Mesh Belts
1. Standard Stainless Steel Mesh Belts: The service life in standard environments can reach 4 years; special weave patterns-such as B-type or herringbone-offer even longer lifespans under stable operating conditions.
2. Special Operating Conditions: High-temperature and corrosion-resistant specialty stainless steel mesh belts can last 2–3 years with proper maintenance in applications such as metal heat treatment.
V. Other Special Materials
1. PU Round Belts: In standard power transmission applications, flex-resistant and wear-resistant models can last 1–2 years, with a temperature tolerance range of -35°C to 80°C.
2. Plastic modular belts (POM/PP/PE): In food conveying applications, they can last 2–3 years with proper use; the low-temperature PE version has a service life of approximately 1–2 years in freezing line applications.
