The Regina 520 RH2 Series Roller Chain is a heavy-duty chain supplied in a 25-foot length for demanding power transmission and conveyor applications. Manufactured by Regina, this alloy carbon steel roller chain is designed to provide dependable performance where increased tensile strength, fatigue resistance, and long service life are required. The manufacturer part number and vendor part number are both 135RH2/25FT.
Fitment: This chain is suitable for equipment and drive systems specified for Regina 520 RH2 Series chain. Confirm the chain series, pitch, sprocket compatibility, and application requirements before installation. The 25-foot continuous length supports maintenance, replacement, and custom-length applications across industrial machinery, material handling equipment, agricultural equipment, and other compatible power transmission systems.
The 520 RH2 Series construction uses larger-diameter alloy carbon steel pins and thicker plates to improve tensile strength and resistance to fatigue under repeated loading. Extended bushings and solid rollers help enhance durability, support smooth engagement with compatible sprockets, and reduce wear during operation. Proper lubrication, alignment, tension, and routine inspection are recommended to help maximize chain performance and service life.
