Jeffrey Chain
 Ramsey Products

Key Features:
Close control of material specifications to ensure consistent response to heat treatment
Renold’s new improved plate profile ensures optimum stress distribution for greater reliability
Fatigue life is enhanced by shot peening and other pre-stressing processes on plates, bushes and rollers
Renold’s special holing processes for oilfield chain were specifically developed to give improved fatigue resistance while minimizing susceptibility to stress corrosion cracking.
Bearing pins undergo customized heat treatment and surface finish operations to ensure unsurpassed toughness and wear life
Closely controlled tolerances ensure smooth robust running even at high speeds.
Specially formulated factory lubrication gives substantially better initial wear performance and enhanced corrosion resistance.
Detachable chains for ease of fitting and replacement
All chains are proof loaded before packing in durable containers
Roll pins standard for extra security


Key Features:
All Renold chains manufacturing and assembly processes are monitored by Statistical process control in conformance with ISO 9000 Quality systems
Consistent overall tolerances make it ideal for conveying systems requiring precise alignment on multi-strand chain layout.
Maximum chain strength and resistance to wear are achieved by strict control of the material specification, and by using state of the art heat treatment processes
Special materials selected for the unique combination of demands from the cement industries.
Fatigue life is improved by maintaining precise fits and tolerances between the pins, bushes and side plates
Chain and sprocket life are optimized by the rigid control of pitch accuracy, resulting in excellent gearing, lower friction and reduced wear.
Bush and roller life are maximized by controlling the concentricity of these components and careful selection and control of the heat treatment process
Breaking loads exceed the minimum international standards, and chains are able to be supplied with breaking loads up to a maximum of 5000kN
Strict control of inner and outer plate clearance ensures effective lubricant penetration. Renold’s use of specially formulated lubricants provides maximum protection and thus minimum wear
Installation and maintenance guides available.
