British Standard Long Pitch Link Chain | Cranked Link Chain for Industrial & Marine Applications

Product Overview

The British Standard long pitch link chain is a cranked link chain designed for industrial transmission and conveying applications. It is manufactured as a compact ring chain structure with cranked links and is commonly used in textile machinery, packaging machinery, conveying equipment, agricultural machinery, mining equipment, electric vehicles, food machinery, and marine-related equipment.

This page focuses on the supplied British Standard long pitch link chain data. The chain is a mechanical power / conveying chain product and should not be confused with lifting chain, anchor chain, mooring chain, or safety chain. Final chain selection should consider pitch, sprocket compatibility, operating environment, speed, lubrication, corrosion protection, and required mechanical strength.

Public standards references show that cranked link chain dimensions and performance are covered in industrial chain standards, while supplier information identifies this product family as a BS / ISO / DIN / JIS / GB compatible cranked link chain. The exact applicable standard edition should be confirmed before production. citeturn0search0turn0search2

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm chain type: cranked link chain, long pitch chain, or other chain family according to equipment requirement.

Step 2: Confirm pitch, chain width, sprocket compatibility, operating speed, load condition, and installation environment.

Step 3: Confirm material grade, heat treatment, surface treatment, corrosion condition, and temperature requirement.

Step 4: Confirm whether the application is conveying, transmission, textile machinery, packaging machinery, agricultural machinery, mining equipment, or marine equipment.

Step 5: Confirm required test load, breaking load, inspection document, coating requirement, quantity, and delivery destination.

Structure

Cranked link plates | Pins | Bushes | Welded chain joints | Compact ring chain structure | Surface treatment layer

Engineering & Application Advantages

• Cranked link construction allows compact chain arrangement for machinery where standard straight link chain geometry is not suitable.
• The chain is selected primarily by pitch, dimensions, sprocket compatibility, and mechanical strength rather than by marine mooring terminology.
• Surface treatment options such as chrome plating or customer finishes can improve corrosion resistance depending on working environment.
• Correct lubrication, alignment, sprocket matching, and maintenance are essential for chain service life.
• Breaking load and test load values should not be interpreted as lifting capacity without specific certification and application approval.
• Marine use should be confirmed separately because this product is not the same category as anchor chain, mooring chain, or towing chain.

Custom Attributes

• Chain Type: Cranked Link Chain → long pitch chain structure for industrial applications.
• Standard: British Standard long pitch link chain → exact BS / ISO / DIN / JIS / GB standard edition to be confirmed.
• Material: Alloy steel etc. → exact material grade and mechanical properties to be confirmed.
• Surface Treatment: Chrome plating or customized treatment → selected according to corrosion and wear requirement.
• Structure: Flash Butt Welded Chain → production method from supplied specification.
• Application: Textile, conveyor, packaging, food machinery, agricultural, mining, electric vehicle, marine equipment → confirm actual duty before selection.

How It Works

Chain engages with matched sprocket or drive system → Cranked links transmit motion and force → Welded joints and pins carry chain tension → Lubrication and alignment maintain operating performance

FAQ

Q1: Is this chain suitable as lifting chain?

A1: No. The supplied product data describes a cranked link chain for machinery and conveying applications. It should not be used as lifting chain without a specific lifting certification and approval.

Q2: How should the correct chain size be selected?

A2: Confirm pitch, chain dimensions, sprocket matching, operating speed, load condition, environment, and required mechanical strength.

Q3: Can this chain be used for marine applications?

A3: The supplied data mentions ships and marine equipment among applications. Actual marine use should confirm corrosion protection, material requirement, and operating conditions.
