Product Overview:

Impact idlers are rotating components specifically designed for belt conveyors to support the belt and bear the weight of conveyed material. Installed below the conveyor's loading zone, they reduce the impact of falling material on the belt, extending belt life. With high toughness, corrosion resistance, flame retardancy, and anti-static properties, they are ideal for mining, chemical, coal washing, and similar industries.

Product Features:

High Toughness & Durability: Impact idlers have toughness exceeding ordinary metal by over 10 times and a lifespan five times longer than traditional column shoes, ensuring long-term durability in harsh environments. Corrosion Resistant & Flame Retardant: Suitable for corrosive environments, resistant to chemical erosion, and flame retardant for safety. Anti-Static Properties: Complies with MT113 standard, effectively reducing static accumulation, suitable for coal mines and other static-prone areas. Lightweight Design: Lightweight for easy installation, maintenance, and reduced pressure on the belt. Double Sealing Structure: Dual-layer sealing effectively prevents dust and water ingress, protecting internal bearings and seals, extending service life.

Technical Parameters:

Radial Runout: Strictly controlled within specified values for smooth operation. Axial Movement: Axial displacement less than 1.2mm under 500N axial load. Rotational Resistance: Rotational resistance below specified value at outer circumference linear speed of 2.0m/s. Drop Strength: After drop test, no damage or detachment; axial displacement ≤1.2mm. Axial Load: No detachment after applying specified axial load. Service Life: ≥20,000 hours. Rubber Ring Material: Flame retardant and anti-static properties comply with MT113.

Installation & Maintenance:

Installation Principle: Increase installation density; replace damaged idlers promptly; install buffer airlocks for large drop heights. Removal Method: Provides simple steps for easy maintenance and replacement. Maintenance: Regular cleaning, inspection of seals and bearings ensures good operation.

Transport & Storage:

Transport: Packed and bundled for land or water transport. Storage: Protected from rain and moisture; stored in a sheltered warehouse.

Suitable Environment:

Ambient Temperature: -10~+40°C Underground Air Composition: Complies with "Coal Mine Safety Regulations" Working Environment: Permits water spray. Adapts to normal handling and installation impacts.

Compliance Standard:

This product complies with MT821-2006 "Technical Conditions of Idlers for Coal Mine Belt Conveyors".

Model Meaning:

Impact Idler Φ89-108, where Φ denotes diameter code, 89 denotes diameter.

Structure and Composition:

Impact idlers use thick-walled seamless tubes. Surface rubber rings employ a double sealing structure, including dust seal rings and sealing rings inside the bearings, KA series impact idler-specific bearings, labyrinth seal inner/outer seal rings, retaining rings, protective covers, and rubber rings.

Product Advantages:

Impact idlers are lightweight with low rotational inertia. Special polymer material weighs about half that of ordinary idlers, reducing friction between idler and belt. Choose our impact idlers for stable, efficient support of your conveying system, ensuring continuous and safe material transport.
