Rubber Ring for Belt Conveyor Roller

A rubber ring for a conveyor roller — also called a rubber disc, impact ring, or buffer ring — is a protective component fitted around belt conveyor idler rollers. It helps absorb impact, reduce belt wear, minimize noise, and protect the roller shell in heavy-duty or loading-point areas.

Function of Rubber Rings

• Impact absorption: Protects rollers and belts from shock at loading zones.
• Material protection: Prevents damage from falling rocks, ores, or lumps.
• Noise reduction: Damps vibration during belt contact.
• Belt tracking: Improves belt alignment and reduces slipping.
• Wear reduction: Extends roller and belt life.

Types of Rubber Rings

Standard Dimensions

Rubber rings are usually defined by:

• Inner Diameter (ID): Matches roller tube or shaft
• Outer Diameter (OD): Matches idler roller outer size
• Thickness / Width: 10–50 mm depending on model

Material Options of Ring Material

Installation of Rubber Ring

• Mounted on steel idler roller shell by press-fitting or vulcanizing.
• Usually spaced 10–20 mm apart for self-cleaning and flexibility.
• Used mainly on impact idlers and return rollers.

Would you like me to provide a dimension chart for impact idler rollers with rubber rings (including number of rings per roller and spacing)? That would help if you're designing or sourcing for a specific belt width (e.g. 800 mm or 1000 mm).
