Conveyor Belt Presents the Durable and Efficient General Roller belt conveyor roller manufacturers

Product Overview:

General Rollers are built to last, with a service life exceeding 10,000 hours. They come with a one-year warranty, and any quality issues within this period are covered by a "one-for-one" replacement policy. This demonstrates the manufacturer's confidence in the product's durability.

Technical Specifications:

• Shaft: Made of bright drawn steel with a roughness of 0.8 μm. The diameter is 0.005 mm larger than the bearing inner diameter, ensuring a tight fit (interference fit) that prevents axial displacement and supports axial loads.

• Tube: Constructed from ordinary welded pipes with a wall thickness ranging from 2.5 mm to 4 mm. The ellipticity is between 0.7 mm and 1 mm, and the resulting radial run-out of the roller is between 0.7 mm and 1.0 mm.

• Bearing: Double-sealed, non-contact bearings with no V-groove on the inner ring. They are lubricated with Great Wall lithium-based grease, suitable for temperatures from -10°C to +120°C. The bearings are dustproof but not waterproof, with a C3 clearance and a noise level of 43 to 45 dB.

• Seal: A 7-piece seal, including 4 nylon parts and 3 iron parts. The middle is filled with 2/3 Great Wall lithium-based grease, providing effective dust and water resistance.

• Circlip: Made of 2 mm thick 65Mn spring steel.

• Surface Treatment: The tube undergoes a special rust removal process to enhance paint adhesion. The roller is coated with ordinary anti-rust paint, available in various colors.

• Packaging: The rollers are shipped without individual packaging, then bundled together.

My Questions as a User and How General Rollers Provide the Answers:

1. What is the expected lifespan of a General Roller?

• Answer: General Rollers are designed for durability, boasting a service life of over 10,000 hours.

2. What kind of warranty is offered?

• Answer: They come with a one-year warranty. If any quality issues arise during this period, you'll receive a replacement for each faulty roller (one-for-one replacement).

3. How is the shaft designed to ensure stability?

• Answer: The shaft is made of bright drawn steel with a precisely controlled diameter that's 0.005 mm larger than the bearing's inner diameter. This creates an interference fit, preventing axial movement and ensuring the shaft can handle axial loads.

4. What is the radial run-out of the roller?

• Answer: Due to the tube's ellipticity of 0.7 mm to 1 mm, the radial run-out of the finished roller is between 0.7 mm and 1.0 mm.

5. What type of bearing is used, and what are its characteristics?

• Answer: The rollers use double-sealed, non-contact bearings. They are lubricated with Great Wall lithium-based grease, operational between -10°C and +120°C. They are dustproof but not waterproof, with a C3 clearance and a noise level of 43-45 dB.

6. How effective is the sealing mechanism?

• Answer: The General Roller features a 7-piece seal (4 nylon and 3 iron parts) with 2/3 of the space filled with Great Wall lithium-based grease. This design provides effective protection against dust and water.

7. What is the surface treatment process for the roller?

• Answer: The tube undergoes a special rust removal process to improve paint adhesion. It's then coated with ordinary anti-rust paint, and you can choose from different colors. 

Conclusion:

The General Roller presents a practical and cost-effective solution for applications involving small belt conveyors or indoor operations. Its robust design, coupled with a reassuring warranty and reliable performance metrics, makes it a sensible choice for users seeking a balance between affordability and durability. The detailed technical specifications provided offer transparency and allow for informed decision-making. While they may not be suitable for heavy-duty or extremely harsh environments, General Rollers excel in their intended applications, providing reliable performance and good value for money.
