Key Product Features

Dynamic Load

High Dynamic Load Endurance

Fabricated from high-tensile alloy steels (such as 40Cr and 20CrMnTi) with optimized plate thickness, increasing yield strength and dynamic shock tolerance under heavy impact loads.

1

Precision Attachment Compatibility

Engineered to accommodate standard and custom attachments (e.g., K1, K2, M1, WA-1, WA-2). Precision hole-pitch tolerances reduce mounting alignment error during installation.

Low Friction

Low-Friction & Smooth Motion

CNC-turned rollers paired with cold-extruded seamless bushings help balance contact stress and minimize velocity fluctuations along the pitch line.

2

Hardened Wear Surfaces

Side plates and bushings undergo controlled atmospheric heat treatment (achieving case hardness typically between HRC 58–62), substantially improving abrasive wear resistance along guide rails.

Technical Specifications & Attachment Parameters

We supply standard ISO, ANSI, DIN, and BS series, along with customized engineering specifications: 

Parameter Standard Range / Technical Specification
Pitch (P) Standard options ranging from 38.1 mm to 300+ mm
Ultimate Tensile Strength (UTS) Heat-treated alloy steel formulations achieving high breaking load ratings
Pin Diameter & Bushing Thickness Induction-hardened pins with precision-ground outer surfaces
Side Plate Thickness (T/t) Thickened plate profiles engineered for minimal lateral deflections
Attachment Configurations K-type, M-type, extended pins, scraper plates, and custom bracket geometry

FAQ

How do I customize a non-standard attachment for my conveyor chain?

You can provide technical drawings (STEP, DWG, PDF) or worn samples. Our engineering team evaluates material compatibility, load distribution, and dimensional clearances before issuing a production drawing.

Can you produce custom attachments that fit existing third-party sprockets?

Yes. By matching pitch, roller diameter, and inner link width, custom attachments can be engineered for drop-in compatibility with existing drive setups.

What manufacturing tolerances are applied to attachment hole locations?

Standard attachment hole spacing is typically held within ±0.05 mm to ±0.1 mm, ensuring smooth bolt-on installation on site.

Can different attachment types be integrated onto a single conveyor chain strand?

Yes. Strands can be configured with alternating attachment spacing (e.g., K1 attachments every 2nd or 4th pitch) based on material spacing needs.

Are sample attachment links available for fitting tests?

Yes. Pre-production samples can be produced for physical check-fitting on your system framework before mass production.

What is the maximum recommended conveyor length for a single drive unit?

Maximum conveyor length depends on total linear mass, coefficient of friction, drive power, and allowable chain pull. Long-span systems often utilize catenary calculations or intermediate drives to control chain tension.

How do you calculate the minimum required breaking strength?

Calculations take into account payload, incline angle, sliding friction factors, thermal conditions, and dynamic startup shock loads, typically applying a working safety factor of 6:1 or higher.

Which chain materials are suitable for elevated temperature environments?

Heat-resistant alloy steels or specialized stainless steel grades with high-temperature synthetic lubricants are recommended for operating temperatures up to 400°C.

How can wear be controlled in abrasive or dusty operating environments?

Utilizing induction-hardened components, sealed joint designs, and dry-film lubricants helps reduce abrasive particles from entering internal bearing surfaces.

Can these conveyor chains be used for vertical or steep-incline transport?

Yes. Deep link plates, side-roller attachments, or scraper flights can be specified to support material retention during inclined conveying.

How can chain jamming and derailment be prevented during operation?

Proper sprocket alignment, correct catenary sag tension, and durable UHMW-PE or hardened steel wear strips help ensure reliable chain tracking.

What are the common causes of accelerated pin and bushing wear?

Insufficient lubrication, ingress of abrasive particulates, angular misalignment, and operating beyond the rated dynamic tensile capacity are common contributors.

How often should catenary tension be checked?

Initial inspections are recommended after the first 24–48 hours of operation to account for seating stretch, followed by periodic monthly maintenance routines.

What wear strip materials work best with steel conveyor chains?

Hardened alloy steel guide rails or low-friction UHMW-PE liners are commonly paired to reduce slide friction and prolong link plate life.

At what point should a conveyor chain be replaced due to elongation?

Conveyor chains are typically recommended for replacement when cumulative pitch elongation reaches 1.5% to 2.0% over a 10-pitch test section.

How are conveyor chains packaged for ocean transit?

Strands are coated with rust-preventative oil, wrapped in sealed moisture-barrier plastic, and secured inside export-grade wooden crates or reinforced steel pallets.

Can chains be pre-cut to specific section lengths for easier site handling?

Yes. Chains can be delivered pre-assembled into specified strand lengths (e.g., 3-meter or 10-foot lengths) equipped with connecting links.

What is the typical production lead time for custom conveyor chain orders?

Standard series items typically ship within 15–20 days, whereas custom attachment configurations generally require 25–35 days depending on tooling requirements.

What documentation is supplied for international customs clearance?

Standard export documentation includes Commercial Invoices, Packing Lists, Bills of Lading, Certificates of Origin, and Factory Material Test Reports.
