Corrosion Resistant/Dacromet-Plated Chain (25DR, 35DR, 41DR, 50DR)

Dacromet-Coated Roller Chain for Corrosion-Resistant Industrial Power Transmission

Our Dacromet-Plated Chain is a corrosion-resistant roller chain designed for industrial power transmission and conveying applications where conventional surface treatments may not provide sufficient environmental protection.

Featuring a Dacromet-based protective coating on the chain components, the chain provides enhanced resistance to corrosion, moisture, salt exposure, and demanding industrial environments while maintaining reliable mechanical performance.

It is suitable for machinery, conveyors, outdoor equipment, automotive production systems, agricultural machinery, material handling equipment, and other applications requiring improved corrosion protection and dependable chain operation.

Key Features

1. Dacromet-Based Corrosion Protection

The Dacromet coating provides a protective barrier against moisture and corrosive environments, helping extend chain service life under demanding operating conditions.

2. Enhanced Corrosion Resistance

Compared with untreated or standard-finished carbon steel chain, Dacromet-plated chain offers improved resistance to atmospheric corrosion, humidity, salt exposure, and industrial contaminants.

3. High-Strength Steel Construction

The chain is manufactured from selected steel materials and precision-processed components to provide reliable tensile strength, wear resistance, and dimensional stability.

4. Reliable Power Transmission

Precision-manufactured pins, bushings, rollers, and plates help maintain smooth engagement with sprockets and stable power transmission during continuous operation.

5. Suitable for Harsh Industrial Environments

Dacromet-coated chains are particularly suitable for applications exposed to outdoor conditions, moisture, road salt, industrial humidity, and other corrosive environments.

6. OEM & Custom Manufacturing

Chain pitch, dimensions, attachments, coating specifications, strength requirements, and packaging can be customized according to equipment requirements and customer drawings.

Technical Specifications

Note: Actual dimensions, tensile strength, coating thickness, operating temperature, and corrosion-resistance performance depend on the selected chain size, steel grade, coating system, and application conditions.

Dacromet Coating Technology

Dacromet is a zinc-aluminum flake-based coating technology used to improve the corrosion protection of steel components.

Unlike conventional electroplated zinc finishes, a Dacromet-type coating is generally applied through a controlled coating and curing process. The resulting protective layer helps isolate the steel substrate from moisture and corrosive media.

For roller chains, Dacromet coating can be applied to selected chain components to improve corrosion resistance while maintaining the dimensional requirements necessary for proper chain and sprocket engagement.

Typical Advantages

• Improved resistance to atmospheric corrosion

• Better protection in humid environments

• Suitable for outdoor machinery

• Good resistance to salt-containing environments

• Uniform protective coating on complex components

• Reduced risk of conventional zinc-plating-related hydrogen embrittlement concerns when an appropriate Dacromet process is used

• Suitable for demanding industrial applications

Actual coating performance depends on the coating formulation, pretreatment, coating thickness, curing process, substrate material, and service environment.

Chain Construction

A Dacromet-plated roller chain consists of multiple precision-manufactured components working together to provide reliable mechanical transmission.

Outer Plates

High-strength steel outer plates provide structural support and transmit tensile loads through the chain.

Inner Plates

Inner plates connect the chain assembly and work together with the bushings and rollers during sprocket engagement.

Pins

Precision-ground pins connect the inner and outer plates and are designed to withstand repeated tensile and articulation loads.

Bushings

Bushings provide the bearing interface between pins and rollers, contributing to smooth chain articulation and wear resistance.

Rollers

Rollers engage with the sprocket teeth to reduce friction and provide smooth chain movement.

Protective Coating

The Dacromet-based coating provides additional surface protection against moisture and corrosion.

Dacromet Chain vs. Conventional Surface-Treated Chain

Performance varies according to coating system, chain specification, environment, lubrication, and operating conditions.
