What Is a U-Type Cover Chain?

Our U-Type Cover Chain is a specialized conveyor chain featuring a U-shaped cover attachment (typically made of stainless steel or engineering plastic) securely mounted onto the chain’s link plates. This U-cover design provides a smooth, enclosed channel that protects conveyed products from contamination, guides small items along the conveying path, or serves as a carrying surface for delicate or irregularly shaped loads. Manufactured in accordance with ISO 606 and ANSI B29.1 standards, this chain combines the reliable performance of precision roller chain (available in short pitch or double pitch configurations) with custom‑formed U‑covers that shield the chain’s moving parts from debris while ensuring stable product handling.

Key Features of U-Type Cover Chain

• Precision‑formed U‑covers available in various depths and widths to accommodate different product sizes

• Secure cover attachment via welding, riveting, or snap‑fit methods

• Heat‑treated pins and bushings for extended wear life

• Pre‑stressed assembly to minimize initial elongation and maintain consistent pitch accuracy

• Smooth, enclosed conveying surface that prevents small parts from falling into the chain

• Easy‑to‑clean cover designs available for hygienic applications

Technical Specifications of U-Type Cover Chain

• Underlying chain series: Short pitch (metric 06B–16B or inch 40–60) or double pitch (C2040–C2060)

• Cover material options: Stainless steel (304 or 316), carbon steel, or FDA‑compliant engineering plastic

• Cover dimensions: Width, height, wall thickness – customized to customer requirements

• Cover spacing: Every pitch, every second pitch, or custom intervals

• Tensile strength: Based on underlying chain series – refer to data sheet per model

• Operating temperature range: Depends on material – stainless steel: -20°C to +200°C; plastic: -10°C to +80°C typical

Applications of U-Type Cover Chain

• Food processing conveyors where product contamination must be prevented

• Packaging lines for small, sticky, or irregularly shaped items

• Pharmaceutical manufacturing and electronics assembly

• Material handling systems where debris could jam the chain or contaminate products

• Conveyors requiring a smooth, enclosed carrying surface for delicate loads

Customization Options for U-Type Cover Chain

• Cover materials: Stainless steel 304/316 (washdown), carbon steel with plating, or FDA‑compliant plastic

• Cover profiles: Solid (maximum protection), perforated (drainage), or custom shapes

• Attachment methods: Welded, riveted, snap‑fit, or removable hinged covers

• Underlying chain: Carbon steel, stainless steel, or plastic inner link versions

• Cover spacing and dimensions: Fully customizable to product size and conveyor layout

• Special finishes: Electropolished, passivated, or anti‑stick coatings for stainless steel

Quality & Compliance of U-Type Cover Chain

• Manufactured under ISO 9001 quality management

• Full material traceability with stainless steel mill certificates available upon request

• FDA compliance available for plastic covers in direct food contact applications

• Dimensional verification to ensure consistent quality and cover fit
