Overview: This document provides detailed technical specifications for various types of stainless steel roller chains, including special roller chains, short pitch roller chains, double pitch roller chains, and conveyor chains. The data is organized primarily by chain type and standard (DIN/ISO and ANSI), with key mechanical and dimensional parameters listed for each chain model.

1. Chain Specifications and Parameters

The document lists multiple chain models with their corresponding dimensions and mechanical properties. Key parameters include:

• Pitch (P): Distance between chain pins, in millimeters.
• b1 (min): Minimum inner width of the chain link.
• D (max): Maximum roller diameter.
• Q min (kN): Minimum ultimate tensile strength, indicating the maximum load the chain can withstand.
• q (kg/m): Chain weight per meter.
• d, d1, d2 (mm): Pin diameters or related dimensions.
• L, L1, L2, L3 (mm): Various link length dimensions.
• h, H, H1, H2 (mm): Heights and thicknesses of chain components.
• t/T (mm): Thickness of plates or attachments.
• Other dimensions: Including widths (W, W1, W2), distances (E, E1, E2, F, C1, C2), and attachment sizes.

2. Chain Types Covered

• Stainless Steel Special Roller Chains: Standard roller chains with detailed mechanical strength and dimensional data.
• Stainless Steel Short Pitch Roller Chains and Attachments: Chains with smaller pitch sizes, including bushing chains without rollers.
• Stainless Steel Double Pitch Roller Chains and Attachments: Chains with double pitch length, suitable for specific applications requiring longer link spacing.
• Stainless Steel Conveyor Double Pitch Roller Chains: Designed for conveyor applications, with specific dimensional and strength parameters.
• Transmission Double Pitch Roller Chains: Chains used in transmission systems with detailed mechanical and dimensional data.

3. Standards and Chain Numbering

The chains are identified by DIN/ISO or ANSI standards, with chain numbers indicating pitch size and series. For example, 40SS, 50SS, 08BSS, C2040SS, etc. The document includes both metric and imperial dimensions depending on the standard.

4. Mechanical Strength and Load Capacity

The minimum ultimate tensile strength (Q min) is provided for each chain type, indicating the maximum load capacity. This is critical for selecting the appropriate chain for mechanical applications.

5. Connecting Types and Recommendations

• For chains smaller or equal to certain sizes (e.g., C2060HSS or 2060SS), the spring clip type connecting method is preferred.
• For larger chains (e.g., C2080HSS or 2080SS and above), cottered type connecting is recommended.
• Similar recommendations apply for short pitch chains, with spring clip preferred for smaller series and cottered for larger series.

6. Special Notes

• Bushing chains without rollers are marked with an asterisk (*) and have specific dimensional and strength characteristics.
• Dimensions such as L1, L2, H1, H2, and others are critical for attachment compatibility and chain installation.

7. Summary of Key Data Tables

The document contains extensive tabulated data for each chain type, including:

• Pitch sizes ranging from 5 mm to over 100 mm.
• Ultimate tensile strengths from approximately 1.49 kN up to over 50 kN depending on chain size and type.
• Chain weights varying from under 0.1 kg/m for small chains to over 13 kg/m for large chains.
• Dimensional data critical for design and manufacturing, such as roller diameters, pin diameters, link widths, and attachment sizes.

8. Practical Application Guidance

When selecting stainless steel roller chains, consider the following:

• Match the chain pitch and size to the mechanical load and application requirements.
• Use the recommended connecting type based on chain size for optimal performance and durability.
• Refer to the detailed dimensional data to ensure compatibility with sprockets and attachments.
• Consider the chain weight and tensile strength to balance strength and efficiency.

Conclusion: This technical document serves as a comprehensive reference for engineers and designers specifying stainless steel roller chains across various standards and applications. It provides essential mechanical and dimensional data, along with recommendations for connecting types, ensuring proper chain selection and application.
