Product overview

Product Overview

Junxin manufactures DTII(A) impact idlers with resilient rings that support the belt and cushion material loading at conveyor feed and transfer zones. The roller diameter, face length, impact-ring arrangement, shaft ends and bearing configuration are selected for the loading position and installed frame.

For new projects, selection is based on the belt width, material, lump size, drop conditions and conveyor arrangement. For replacement enquiries, an existing drawing, roller dimensions or installation photographs help us confirm the required interface before production.

Ordering and technical questions

Before You Request a Quote

Where are impact idlers normally installed?

They are normally installed below loading and transfer points where falling material creates higher impact on the conveyor belt.

What information is needed for an impact-idler quotation?

Provide roller diameter and length, shaft ends, bearing reference, belt width, loading position, material and lump information, and required quantity.

Can an impact idler be manufactured as a direct replacement?

Yes. Junxin can review an existing drawing, measured roller dimensions or installation photographs before confirming the replacement configuration.
