BIS CERTIFICATION FOR SHORT – PITCH TRANSMISSION PRECISION ROLLER AND BUSH CHAINS, ATTACHMENTS AND ASSOCIATED CHAIN SPROCKETS IS 2403

Published Date: April 10, 2025 4 min Read

BIS certification is essential for Short-Pitch Transmission Precision Roller and Bush Chains, Attachments, and Associated Chain Sprockets as per IS 2403:2014. This standard ensures that roller and bush chains used in mechanical power transmission systems meet stringent performance and quality benchmarks. These components are critical for transmitting mechanical power in industrial machinery, conveyors, and automotive applications. Certification verifies their conformity to standards related to dimensional accuracy, strength, wear resistance, and compatibility with associated sprockets, thereby ensuring reliable and efficient power transmission across various mechanical systems.

IS 2403:2014 – Short-Pitch Transmission Precision Roller and Bush Chains, Attachments and Associated Chain Sprockets

This standard specifies the requirements, dimensions, and testing methods for short-pitch transmission precision roller and bush chains along with their attachments and matching sprockets. It defines chain series, constructional details, and materials to ensure uniform performance and interchangeability. The standard also lays out detailed parameters for chain pitch, roller diameter, tensile strength, and breaking load to ensure operational reliability under demanding mechanical conditions. These chains are widely used in industrial applications where high strength and durability are critical for sustained performance.

Benefits of BIS Certification for Transmission Chains and Sprockets

BIS certification under IS 2403:2014 provides assurance of quality, consistency, and safety for manufacturers and users. For manufacturers, certification offers credibility, access to regulated markets, and increased customer trust. It ensures that products meet required specifications for dimensional accuracy, durability, and mechanical strength. For users, certified chains and sprockets guarantee compatibility and reduce the risk of mechanical failure, leading to improved operational efficiency and reduced maintenance costs in critical systems such as industrial machinery, packaging units, and agricultural equipment.
