35-Degree Heavy-Duty Impact Idler Set for Conveyor Belt Loading Zone
Product Details
Haihui 35-degree impact idler sets are custom manufactured according to specific customer requirements. These idler assemblies are installed at material loading points where falling material impacts the conveyor belt. The impact idler set absorbs shock energy, protecting both the belt and the supporting structure from damage.
Why Impact Idlers Are Necessary
When material drops onto a conveyor belt from chutes or transfer points, the impact force can be severe. Without proper protection, the belt may suffer cover cracking, carcass damage, or even puncture. Standard carrying idlers are not designed to absorb impact energy. They can crack or break under repeated heavy loading.
Haihui 35-degree impact idler sets solve this problem using specially engineered components.
Custom Trough Angle Design
The 35-degree trough angle is a common standard, but Haihui can adjust the angle to match specific conveyor configurations. Standard angles include 20, 30, 35, and 45 degrees. The correct angle ensures proper belt tracking and material containment while providing effective impact absorption.
Impact Absorption Components
Each impact idler in the set features rubber rings or discs mounted on the roller surface. These resilient components compress upon impact, absorbing shock energy before it reaches the belt. The rubber material is formulated for high elasticity, wear resistance, and tear strength. Haihui offers different rubber compounds based on material temperature, oil exposure, and impact severity.
Roller and Bearing Selection
The roller tube is manufactured from heavy-gauge steel to withstand impact loads. Wall thickness is increased compared to standard idlers. Bearings are selected based on calculated impact load and expected service life. Larger bearings with greater radial capacity are used for severe applications.
Sealing System
Impact idlers operate in dirty environments where dust and fines are present. Seals must protect bearings while allowing free rotation. Haihui uses multi-stage labyrinth seals with added contact elements for fine dust conditions. For wet applications, enhanced water-resistant seals are available.
Custom Dimensions
Idler length is determined by belt width. Non-standard belt widths are accommodated. Roller diameter is selected based on belt speed and impact severity. Larger diameters provide better impact resistance and longer bearing life.
Surface Protection
Idler tubes receive surface protection based on environmental conditions. Standard paint suits indoor applications. Electro-galvanized or hot-dip galvanized coatings protect against corrosion in outdoor, marine, or chemical environments.
Order Process
Customers submit belt width, trough angle, load data, material characteristics, and environmental conditions. Haihui engineers prepare drawings for approval before production begins.
