Loading Zone Belt & Impact Protection

Rubber Cushion Impact Idler Roller for Conveyor Loading Points

Designed specifically for conveyor feed zones and transfer chutes. Heavy-duty segmented rubber rings absorb falling lump impact, preventing belt carcass damage and reducing frame stress.

Maximum Shock Absorption Under High Drop Heights

When heavy lumps of ore, limestone, coal, or rock drop onto a moving conveyor belt, standard steel rollers create severe shock loads that puncture belts and destroy bearings. Our rubber cushion impact rollers replace plain steel shells in loading cradles to dampen impact energy instantly.

High-Energy Absorption

Thick-section wear-resistant rubber discs flex under dynamic lump impact to dissipate kinetic force.

Belt Carcass Protection

Eliminates rigid steel pinch points, preventing longitudinal tearing and ply delamination.

Heavy-Duty Core Shaft

Reinforced cold-drawn round steel shaft resists bending under heavy continuous shock loads.

Recommended Installation Points

Conveyor Loading Chutes: Installed directly below hopper drop zones to cushion lump impact.

Primary Crusher Discharge: Protects belts from sharp, jagged run-of-mine ore and rock.

Conveyor Transfer Towers: Dampens belt stress at high-velocity material diversion points.

Ship Loading & Rail Car Dumps: Handles surge feed impact during high-tonnage bulk unloading.

Frequently Asked Questions

Q1: What spacing should be used for impact rollers under the chute?
Impact idlers are typically placed close together (often 300 mm to 600 mm center-to-center) to form a continuous supportive cushion under the loading chute.

Q2: How do rubber cushion rollers prevent rubber rings from shifting?
Rubber rings are press-fitted under high interference onto the steel core and locked in place with welded steel end retaining rings.

Q3: Can these impact rollers be used in coal mines requiring flame retardancy?
Yes. We supply certified FRAS (Flame-Retardant and Anti-Static) rubber rings suitable for underground mining safety standards.
