Comb Idler

Comb Idlers feature hard rubber sleeves and a comb structure to prevent belt misalignment, designed for sticky material handling on belt conveyors.

Quality Impact Factors

Axial float - Directly affects service life.

Radial runout - Determines material conveying stability (National Standard ≤0.7mm).

Rotation flexibility - Affects idler/belt life & drive power consumption.

Water/corrosion resistance - Determines durability in harsh environments.

Labyrinth seal performance - Prevents dust ingress (IP54 rating).

Axial load capacity - Standard value ≥30kN.

Impact resistance - Must pass JIS K6378 drop test.

Rotational resistance - Standard value ≤2.5N (affects belt energy consumption).

Maintenance Specifications

Design life ≥20,000 hours (per GB/T 10595-2017). Recommendations:

Set maintenance cycles based on conditions (grease every 3 months for heavy-duty).

Promptly clean accumulated material/floating coal between teeth.

Replace abnormal idlers within 48 hours.

Bearing Replacement Standards

Install bearings per marking direction, cage opening facing seal side.

Control axial clearance at 0.1-0.3mm (no over-compression).

Seal Assembly Requirements

Use OEM labyrinth seal kits.

Clean seal grooves before assembly.

Install dual seals independently (no nesting).

Safety Operation Prohibitions

Striking tube body prohibited (light tapping end covers with rubber mallet allowed).

No live maintenance (LOTO procedure mandatory).

Unauthorized disassembly forbidden (seal damage requires full replacement).
