Structural Features

Roller body precision-manufactured from high-quality welded tubing, strictly screened for dimensional tolerance. Axles made from cold-drawn round steel, bearing housings feature stamped steel construction. Equipped with PDC triple-sealing system offering superior dust/water resistance exceeding national standards. Precision assembly ensures excellent load capacity, minimal radial runout, low rotational resistance, 15% weight reduction, and theoretical service life over 30,000 hours.

Structural Design

Three idlers hinged into a group via connecting plates forming a stable triangular structure, flexibly connected to conveyor stringers via hook-type suspension. Enables intelligent self-balancing: when belt misalignment occurs, load imbalance shifts idler angle on the offset side, generating corrective force via lever principle for automatic trajectory correction.

Performance Advantages

Strong corrosion resistance: withstands long-term erosion by acids, alkalis, salts.

Ultra-high wear resistance: Roller surface hardness ≥ HRC55, wear resistance index increased by 3x.

Triple sealing: Labyrinth seal + rubber oil seal combination ensures complete bearing chamber sealing.

Low-friction surface: Ceramic coating forms smooth oxide film, friction coefficient reduced by 40%.

Extended service life: 2-5x longer than conventional idlers, reduces belt wear.

Significant economy: Reduces downtime/maintenance frequency, lowers overall O&M costs by 35%.

Usage & Maintenance

Pre-installation: Check roller surface integrity, manually rotate to ensure no jamming.

Set spacing reasonably based on material properties (recommended: 1.2-1.5m).

Regularly inspect seal condition during operation, replenish special grease quarterly.

Avoid unnecessary disassembly of installed idlers to prevent structural accuracy loss.
