1. High Precision Shaft
The shaft is manufactured from precision-machined round steel, providing excellent wear resistance, corrosion resistance, and long-term operational stability across various industrial applications.
2. Durable Roller Tube
The roller tube is processed with advanced polishing equipment to achieve a smooth surface finish, improving coating adhesion and corrosion protection.
Tube thickness: 2.5mm – 4.0mm
Diameter range: 50mm – 219mm
Surface treatment options include powder coating and baked paint, ensuring durability in demanding environments.
3. High-Quality Sealed Bearing System
Equipped with deep groove ball bearings and a double labyrinth sealing system, the roller provides excellent protection against dust and water ingress.
Temperature range: -35°C to +160°C
Low noise operation: 39–42 dB
Clearance: C3 standard for high-speed and heavy-load conditions
Premium grease is used to ensure smooth rotation and long service life, even in extreme climates.
4. Advanced Multi-Layer Sealing Structure
The sealing system adopts a multi-stage design combining engineering plastic and steel components to enhance dustproof and waterproof performance. Internal lubrication is optimized to maintain stable bearing operation over extended periods.
5. High Strength Retaining Components
The retaining ring is made of spring steel, offering high strength and durability, ensuring stable assembly and long-term reliability under continuous operation.
6. Enhanced Surface Treatment
The roller surface is finely polished to improve coating adhesion, resulting in better corrosion resistance. Multiple finishing options are available to meet different environmental requirements.

Summary:
For conveyor roller design selection, the shaft and roller dimensions are typically matched according to belt width and load requirements to ensure stability and durability.
When the belt width is B ≤ 800mm, rollers are commonly equipped with an 89mm diameter tube. For wider applications where B > 800mm, a larger 108mm roller diameter is generally recommended to provide better load-bearing performance.
In terms of shaft sizing, different roller diameters require corresponding shaft diameters for safe operation and structural strength:
- 89mm rollers typically use a 20mm shaft
- 108mm and 133mm rollers are generally matched with a 25mm shaft
- 159mm heavy-duty rollers are usually equipped with a 30mm shaft
The shaft length is normally designed to be slightly longer than the roller body, usually calculated as the roller length plus 30mm to 50mm, depending on installation requirements and mounting structure.
