Product Description:
The roller shaft is a core component in industrial drive and conveyor systems, responsible for supporting, transmitting power, and conveying materials. This product is manufactured from high-quality alloy steel, carbon steel, or stainless steel through precision machining, heat treatment (quenching and tempering, hardening, surface hardening), and grinding processes. It features extremely high dimensional accuracy, excellent mechanical strength, wear resistance, and anti-fatigue performance. We provide roller shaft solutions ranging from standard models to fully customized options, widely used in various heavy industries such as mining, metallurgy, papermaking, printing, and logistics conveying, ensuring smooth and efficient equipment operation and extended service life.
Features:
- Exceptional Durability: Made from high-strength alloy materials and treated with heat processes, offering high wear, pressure, and fatigue resistance for long service life.
- High Precision & Balance: Precision machining and dynamic balancing ensure minimal tolerances in body diameter, roundness, straightness, and coaxiality, resulting in smooth operation with low vibration.
- Superior Performance: High load capacity guarantees reliability under heavy load and high-speed conditions; the surface can be finished as needed (smooth, chrome plated, rubber covered, etc.) to meet different friction and traction requirements.
- Wide Compatibility: Multiple standard sizes and structures (solid, hollow, with shoulders, keyways, etc.) adaptable to equipment from numerous domestic and international brands.
• • Comprehensive Customization: Supports non-standard design and manufacturing based on customer's installation space, load, speed, and special working environment requirements.
