1. Product Series Overview

KettenWulf offers a broad range of roller chains tailored for diverse industrial power transmission needs. Key series include:

• S-Series: Premium roller chains surpassing DIN, ISO, and BS standards, featuring solid bushings and high-alloy steel pins for enhanced fatigue strength and extended service life. Compatible with standard DIN sprockets.
• HT, E, HE, P, PH, RC, HS, X, HX, NSC, Side-bow, DP, BTK, Ro-drive, RVP, RP Series: Specialized chains addressing heavy-duty, high-performance, oil-field, silent, and flexible drive applications.
• DCS and FK Roller Chains: Standard and heavy-duty chains conforming to DIN 8187/8188, ANSI, and factory standards, including oilfield, super hi-power, silent, leaf, and gall chains.

2. Chain Specifications and Standards

Chains are typically supplied riveted; cottered chains are available on request. Pitch sizes range from 6.35 mm (1/4") to 76.2 mm (3"), with lengths offered in feet and meters. Packaging includes boxes, reels, and cartons, with standard lengths and link counts specified for simplex, duplex, and triplex configurations.

3. Chain Parts and Connecting Links

• Various connecting links are available: roller links, pin links (press fit), spring clip or cottered connecting links in loose, tap-fit, and press-fit variants.
• Offset (crooked) links are strongly discouraged in impulsive, high-load, or high-speed applications due to reliability risks.
• Special connecting links exist for multiple strand chains with heavy press-fit bushed center links.

4. Technical Data and Parameters

Extensive tables provide critical parameters for each chain type and size, including pitch, internal width, roller and pin diameters, pin lengths, plate thickness, height, traverse pitch, bearing surface area, tensile strength (N), and weight (kg/m). These enable precise chain selection based on mechanical and dimensional requirements.

5. Quality and Performance Highlights

• S-Series chains exhibit superior fatigue and wear resistance due to high-quality manufacturing, solid bushings, and high alloy steel pins, resulting in longer service life.
• Heavy-duty HT-Series chains feature thicker plates and hardened pins for enhanced shock resistance and higher permissible loads.
• Standard DIN and ANSI sprockets are compatible with respective chain series, facilitating integration.

6. Packaging and Ordering Guidelines

• Standard chain lengths are typically 10 feet (3.048 m) or 5 meters, including one connecting link per length.
• Exact link counts and connecting parts must be specified for custom cut lengths.
• Packaging varies by chain size and strand type, with detailed tabulations for quantities and lengths.

7. Critical Recommendations and Limitations

• Avoid offset links in high-load, impulsive, or high-speed applications to prevent premature failure.
• Specify riveted or cottered chain types explicitly when ordering; cottered chains are not usually stocked.
• Use standard DIN sprockets with S-Series chains and ANSI sprockets with DCS chains for optimal performance.
• Ensure precise link counts including connecting parts for custom orders.

8. Specialized Chain Series for Oil-Field and Heavy Industrial Applications

• DCS E-Series: Oil-field chains meeting ANSI and API standards with improved fatigue resistance and shock absorption.
• DCS HE-Series: Heavy oil-field chains with thicker plates for higher shock load capacity.
• DCS P-Series and PH-Series: Super hi-power chains with high-grade alloy steel and special heat treatments for exceptional fatigue, shock, and wear resistance; PH-Series features even thicker plates.

These chains offer tensile strengths ranging from ~47,000 N to over 940,000 N, with pitches from 19.05 mm to 76.2 mm, and are available in multiple strand configurations.

9. Drive Chains: Bush, Heavy-Duty Cranked-Link, and Silent Chains

• BTK-Series (Bush Chains): Larger bearing area chains for low-speed and counterweight applications, conforming to DIN 8164, with tensile strengths up to 1,815,000 N.
• FK-Series (Heavy-Duty Cranked-Link Chains): Designed for harsh conditions with high fatigue strength and wear resistance; pitch sizes from 9.525 mm to 25.4 mm.
• RPV and RP-Series (Silent Chains): Inverted tooth chains for high-speed, high-load drives offering smooth operation and high efficiency. RP-Series chains operate on ANSI sprockets and provide significantly higher power capacity than SC chains. Center guide assemblies (single or double) ensure alignment and stability.

10. Chain Dimensions and Mechanical Properties Summary

Key parameters across all chain types include pitch, width, roller and pin diameters, plate thickness, height, bearing surface, tensile strength, and weight. Tensile strengths range widely, from a few thousand Newtons in small chains to several million Newtons in heavy-duty and silent chains. Weight per meter varies accordingly, impacting handling and design considerations.

11. Accessories and Attachments

Various chain parts such as cottered pins (from size 60 upwards), curled bushings, connecting links, and angle plates are available to customize chains for specific applications. References to accessory details are provided (pages 82-88).

12. Standards and Compatibility

Chains conform to international standards including DIN 8187/8188, ISO 606, ANSI, and API, ensuring interchangeability and quality assurance. Compatibility with standard sprockets is emphasized for reliable integration.

13. Recommendations and Best Practices

• Select chain type based on load, speed, environmental conditions, and application demands.
• Use cottered or splinted pins for secure assembly in chains size 60 and above.
• Choose heavy-duty or extra-duty chains for applications requiring enhanced shock resistance and fatigue life.
• Side-bow chains are recommended for curved or twisted chain paths.
• Double pitch chains suit low-speed, light-duty drives and conveyor systems.
• Specify exact chain dimensions and center guide placements for silent chains to ensure proper fit and performance.
