The structural integrity and operational longevity of a flat belt pulley rely directly on metallurgy and precision turning. We select 1215 free-cutting steel for the main body construction due to its optimal balance of mechanical strength and high machinability.
Machinability & Surface Finish: The controlled sulfur content in 1215 steel facilitates smooth cutting during turning and milling processes, minimizing tool wear while achieving fine dimensional tolerances and smooth groove profiles.
Structural Toughness: With a tensile strength of ≥ 420 MPa and elongation of ≥ 22%, the steel body resists deformation under heavy radial loads and dynamic belt tensions.
Vibration and Noise Reduction: High dimensional consistency and uniform wall thickness eliminate rotational imbalance, reducing operational running noise during high-speed belt friction.
Conveyor systems and washing/light industrial machinery frequently operate in humid or moisture-laden environments. Unprotected metal components are vulnerable to surface oxidation and rust, which accelerates belt wear and leads to premature bearing failure.
To ensure long-term durability, each pulley undergoes an automated surface treatment process:
Automated Black Oxide (Blackening): Creates an integrated chemical conversion coating that protects against ambient humidity while maintaining exact mechanical tolerances.
Electroplating (Zinc Coating): Provides a uniform barrier layer with stable adhesion, offering excellent corrosion isolation against moisture and atmospheric exposure.
Maintenance Reduction: The combination of protective surface plating and double-sealed bearings prevents debris ingress and rusting, extending maintenance intervals in continuous-duty applications.
The Flat Belt Pulley With Bearings For Belt Conveyor serves multiple functions across automated conveyor setups and drive systems:
Tail & Bend Pulleys: Facilitates smooth directional changes of the flat conveyor belt with minimal frictional loss.
Tensioning & Take-Up Pulleys: Maintains proper belt tension, preventing slippage during start-stop cycles or load variations.
Industrial Applications: Widely integrated into belt conveyor lines, packaging machinery, washing machines, automated logistics sorters, and small-scale mechanical transmission drives.
HAWEN is the international trade subsidiary of Zhejiang Telilong Precision Machinery Co., Ltd. (formerly Zhejiang Telilong Auto Parts Co., Ltd., established in 2004). Recognized as a National High-Tech Enterprise and Provincial R&D Center, Telilong operates a modern production facility in Lishui, Zhejiang Province.
Production Capacity: Daily output capacity reaches 150,000 precision motor pulleys, backed by nearly two decades of precision mechanical manufacturing experience.
Domestic Market Leadership: Telilong holds a 65%–75% domestic market share in precision motor pulleys, serving leading global appliance and motor manufacturers including Midea, Gree, LG, Nidec, Huilu, and Wolong.
Quality Control: Mass production processes follow rigorous inspection protocols, ensuring 100% compliance with geometric, dimensional, and surface finish tolerances prior to shipment.
We supply precision deep groove ball bearings with standard double-contact rubber seals (2RS) or metal shields (ZZ) to protect against dust, moisture, and debris ingress. Depending on your load, speed, and temperature requirements, we can integrate bearings from top tier brands (e.g., SKF, NSK, TIMKEN) or premium domestic certified suppliers.
Yes. We offer both straight flat face profiles and micro-crowned (tapered) face profiles. A crowned face features a slightly larger diameter at the center than at the edges, which creates a natural self-centering force to keep the flat conveyor belt aligned and prevent belt runoff during operation.
1215 free-cutting steel contains optimized sulfur levels, which provides superior machinability during precision CNC turning. This ensures tighter dimensional tolerances, a smoother surface finish for reduced belt wear, and consistent high-volume production quality while maintaining adequate tensile strength (≥ 420 MPa).
Both treatments provide corrosion resistance, but the choice depends on the operating environment:
Yes. As an established R&D and manufacturing enterprise, we fully support custom orders based on customer drawings or samples. Customization options include outer diameter, face width, bore size, keyways, snap ring grooves, integral shaft designs, and specific surface finishing requirements.
Our facility implements strict in-line and final quality inspection protocols. Every production batch undergoes comprehensive dimensional verification, runout/concentricity testing, dynamic/static balancing (where applicable), and surface coating thickness checks to ensure compliance with client specifications before packaging.
