Friction Head of Roller FAQ: Specifications, Ordering and Support Questions

Buyers, procurement engineers, and maintenance teams regularly ask about the design, specifications, ordering requirements, and support for the friction head used in belt conveyor roller assemblies. The answers below are drawn from Yanshan Aohua Machinery Equipment Manufacture Limited Company's confirmed product documentation.

What is a friction head on a conveyor roller?

The friction head is the end-cap assembly fitted to a friction roller. It houses the bearing support structure and transmits rotational force within the roller. The friction wheel and end cover are manufactured by stamping and welding technology, forming a secure interface between the roller shell and the bearing mounting point.

What makes the patented design different from a conventional roller end?

Yanshan Aohua Machinery Equipment Manufacture Limited Company applies a patented structural approach (Patent No. ZL 2014 20 424753.0) with two key differences:

1. Solid belly workpiece — A solid belly design replaces the conventional hollow structure, reducing workpiece weight, rotational inertia, and rotational centrifugal force.
2. Bearing double-end support — The design changes from double-bearing single-end support to bearing double-end support, making the assembly more reliable, enabling stable rotation, and being described as energy-saving, easy to replace, and hard to damage.

What standards does the friction roller comply with?

Friction rollers are manufactured to CEMA, ISO, DIN, JIS, and DTII standards. Buyers in the US, Middle East, Europe, and Southeast Asia may reference these standards when specifying equipment. Compliance for a specific order should be confirmed at the time of inquiry.

What materials are used in the roller and its end assembly?

• Roller body: Angle steel, channel steel, or steel pipe
• Shaft: Q235B or 1045 high-precision cold-drawn steel
• Friction wheel and end cover: Stamping and welding technology
• Welding: Automatic double-end welding; carbon dioxide gas shielded welding
• Coating: Painting process

Material selection for a specific order depends on application requirements and should be confirmed during the inquiry stage.

What dimensional ranges are available?

Dimensions applicable to the end-assembly within a given roller size should be confirmed with the technical team.

Which bearing brands and types are available?

Bearing brands include HRB, ZWZ, LYC, SKF, FAG, and NSK. Bearing types range from 6203 to 6312. The bearing double-end support configuration is designed for reliable and stable rotation.

What seal types are offered?

Documented seal types: AH, JIS, TR, and DTII. The appropriate choice depends on the operating environment and should be specified at ordering.

Which industries are friction rollers used in?

Applications include coal mines, cement plants, crushing operations, power plants, steel mills, metallurgical facilities, quarrying, printing, recycling industries, and other conveying equipment environments.

What are the ordering terms?

• Minimum order: 1 piece
• Price: Negotiable
• Payment: TT or LC
• Delivery: 10–15 days
• Packing: Fumigation-free plywood box, iron frame, or pallet
• Shipping ports: Tianjin Xingang, Shanghai, Qingdao
• Origin: Hebei Province, China

What after-sales support is available, and what is the service life?

Support options include online support and video technical support. Product documentation states a service life of 30,000 hours. Actual service life depends on operating conditions, installation quality, and maintenance practices.
