Standard Roller Chain Models

Standard roller chains are categorized by pitch size, construction, and international standards. The most common classification systems include ANSI (American) and ISO (International) standards. Below are key models and their specifications:

1. ANSI Standard Roller Chains

Naming Convention: Number-based (e.g., 25, 35, 40, 50, 60, 80).

Common ANSI Models:

#25: Smallest standard chain (pitch: 6.35 mm), used in light-duty applications (e.g., bicycles, machinery).

#35: Pitch 9.525 mm, for moderate loads (conveyors, motorcycles).

#40: Most widely used (pitch 12.7 mm), ideal for industrial machinery, agriculture equipment.

#50/60/80: Heavy-duty chains (pitch 15.88–25.4 mm), used in construction, mining, and forestry.

2. ISO Standard Roller Chains (Metric)

Naming Convention: "B" series (e.g., 04B, 06B, 08B, 10B, 12B, 16B).

Common ISO Models:

04B: Pitch 6.0 mm (ultra-light duty).

06B: Pitch 9.525 mm (matches ANSI #35).

08B: Pitch 12.7 mm (matches ANSI #40).

10B/12B/16B: Heavy-duty (pitch 15.88–25.4 mm).

Dimension

Roller Chains with Attachments
Roller chains with attachments are specialized power transmission components that combine standard roller chain functionality with customized attachment features. These chains are widely used in material handling, conveying systems, and industrial automation where both power transmission and component connection are required.

Key Features

Base Chain Structure

Consists of inner/outer plates, pins, bushings, and rollers

Complies with ANSI/ISO standards for standard pitch dimensions

Attachment Types

Extended inner/outer plates (straight, bent, or offset)

Specialized brackets or lugs welded/riveted to chain links

Common configurations: K-type (single attachment), M-type (double attachment)

Material & Treatment

Carbon steel (standard) or stainless steel (corrosion-resistant)

Optional heat treatment or plating (e.g., zinc/nickel coating)

Primary Applications

Conveyor systems (food processing, packaging lines)

Agricultural machinery (harvesters, balers)

Automotive assembly lines

Escalator step drives

Timber processing equipment

Advantages

Dual functionality: Power transmission + component mounting

Customizable attachment spacing/pitch

High tensile strength (typically 500-2,500 kgf)

Compatible with standard sprockets

Selection Considerations

Attachment type/position relative to chain direction

Required load capacity (static & dynamic)

Environmental factors (temperature, chemicals, moisture)

Maintenance requirements (lubrication frequency)

Common standards: ANSI, ISO  (for attachment dimensions). Proper alignment and tensioning are critical for optimal performance and extended service life.
