More Details For Our Customers

Structure Composition

The stainless steel idler is composed of a stainless steel shell, shaft, bearing, sealing system, and end caps. Depending on the working conditions, 304 or 316L stainless steel is used, combined with high-grade sealing to ensure long-term reliability and cleanliness.

Custom Options & Parameters

Stainless steel idlers are ideal for applications requiring high corrosion resistance and hygiene. We offer flexible customization options to suit a wide range of working conditions.
·Wide Range of Dimensions: Available in standard diameters from φ76 to φ159mm, with roller lengths tailored to belt widths (e.g. 500mm, 1000mm).
·Multiple Steel Grades: 304, 316L, and 201 stainless steel options to balance corrosion resistance and cost for industries such as food, chemicals, and pharmaceuticals.
·Custom Shafts & Bearings: Shaft diameters from φ20 to φ40mm, paired with bearings like 6204, 6205, and 6305 for high load and smooth rotation.
·Surface Finishes: Available with polishing, brushing, or electropolishing for enhanced surface cleanliness and appearance.
·Sealing Systems: Fully enclosed or stainless labyrinth seals ensure protection against moisture, dust, and corrosive agents.

Manufacturing & Quality Control

Our stainless steel idlers are manufactured on modern production lines equipped with CNC machining, automated welding, and clean assembly systems, all under a certified ISO quality management system.
·High-Grade Stainless Materials: Pipes and shafts are made from 304/316 stainless steel compliant with GB or ASTM standards for optimal corrosion resistance and mechanical strength.
·Precision Engineering: Bearing seats and end caps are processed with CNC lathes to ensure high concentricity and stable rotation.
·Automated Welding: All welding is performed by robots or automated systems, guaranteeing consistent and aesthetically clean welds.
·Clean Surface Finishing: Options like polishing and electropolishing are available to meet hygiene requirements in food and pharmaceutical environments.
·Comprehensive Quality Checks: Include raw material verification, dimensional and tolerance inspection, rotation and sealing performance tests—all ensuring compliance with international and customer-specific standards.

FAQ or Maintenance Tips

·FAQ
In corrosive or humid environments, poor sealing can still cause bearing corrosion.
·Maintenance Tip
Check seal integrity regularly, clean thoroughly, and prevent chemical residue buildup.
