Expert answers to common questions about industrial belts, pulleys, and technical specifications.
PVC belts offer excellent chemical resistance and durability at lower cost, ideal for general material handling. PU belts provide superior oil/fat resistance and meet FDA food-grade standards, making them better for food processing and applications requiring higher flexibility.
Select based on load, speed, and precision requirements. HTD (round tooth) profiles handle higher torque. XL/L type (trapezoidal) suit lighter loads. For high-precision indexing, use HTD 5M or 3M profiles.
Aluminum offers lightweight and corrosion resistance for general use. Steel provides maximum durability for heavy loads. Stainless steel (304/316) is required for food/pharmaceutical applications. Plastic pulleys suit lightweight, low-load scenarios.
Belt width depends on load distribution and pulley flange coverage. As a rule, belt width should be 10-20% narrower than the pulley face width to allow for tracking tolerance. For conveyor applications, ensure the belt covers the full load width plus 50mm margin on each side.
Use V-belts for high-speed, high-torque applications where slight slippage is acceptable and cost is a priority. Use timing belts when precise synchronous motion is required, or when maintenance-free operation and higher positional accuracy are needed.
Our ISO 9001:2015 certification covers our entire quality management system including design, manufacturing, inspection, and customer service processes. It ensures consistent product quality, traceability, and continuous improvement across all production lines.
Every batch undergoes incoming material inspection, in-process dimensional checks, final product testing (tensile strength, elongation, hardness), and random sampling per AQL standards. Test reports are provided with each shipment.
Yes. Every product ships with a material certificate showing raw material batch numbers, production date, and test results. For food-grade and pharmaceutical applications, full traceability documentation including FDA/REACH compliance certificates is provided.
Standard belts: 10 pieces. Custom specifications: 50 pieces. Pulleys: 20 pieces for standard sizes, 100 pieces for custom machining. Sample orders below MOQ are accepted at a slight price premium. Contact us for project-specific flexibility.
Standard products: 7-10 business days. Custom specifications: 15-20 business days. Large orders (>1000 pieces): 20-30 business days. Expedited production is available for urgent orders at an additional cost.
We accept PayPal (preferred for smaller orders), wire transfer (T/T), and Letter of Credit for large orders. Payment terms: 30% deposit, 70% before shipment. Net 30 terms available for established customers with approved credit.
Yes, we provide free samples of standard products for qualified customers. Shipping costs are borne by the customer. Custom samples may incur a nominal tooling fee, which is credited against the first production order.
Absolutely. We specialize in custom belts and pulleys. Provide your CAD drawings, specifications, or physical samples. Our engineering team will review and provide DFM feedback within 24 hours. Custom tooling typically takes 10-15 days.
We accept STEP (.step, .stp), DWG, DXF, PDF (with dimensions), and native SolidWorks (.sldprt) files. For belt profiles, we can also work from physical samples. Include all critical dimensions, tolerances, and material specifications with your submission.
Use a belt tension gauge to measure static tension. The correct tension depends on belt pitch, width, and center distance. As a general rule, deflect the belt 1/64 of the span length under moderate finger pressure. Our technical team can provide specific tension values for your application.
We offer plain bore (for set screw mounting), keyway bore (for shaft key mounting), taper lock bushings (easy installation/removal), and custom bore with keyway. Bore sizes range from 6mm to 50mm for standard pulleys, larger by custom order.
Flanges are required on at least one pulley in a belt drive system to prevent belt tracking off the pulley. For long center distances or vertical drives, flange both pulleys. Flange height should be 1-2mm higher than the belt tooth height. We offer single and double-flanged configurations.
Inspect tension monthly, check for cracks or wear every 3 months, and clean pulleys annually. Keep belts away from oil, excessive heat, and UV exposure. Replace belts in pairs or sets to ensure even wear. Properly maintained belts typically last 3-5 years in standard industrial applications.
