Power transmission Roller Chain manufactured by SENQCIA Corporation. Made in Japan
SENQCIAhas achieved numerous results since its establishment over a century ago, specially when focusing on the production and development of engineering and industrial chains, which are supplied according to the different requirements of each customer.
As a comprehensive chain manufacturer, SENQCIA produces roller chains, conveyor chains, cast chains and many other types of chains. We provide a full range of manufacturing processes from machining through heat treatment for assembly based n our expereinces and technolofies accumulated over more than 100 years. SENQCIA is proud thet its products keep contributing to not only to the development and progress of Japan, but of other countries around the world.
Features of Solid Bushing and Roller Chains
In 2009, SENQCIA went into full production of the new Solid Bushing and Rollwe Chain across the standard ranfe. SENQCIA once again were the front runner and introduced new innovations in manufacturing technologies and part processing which has led to the development of the new Solid Bushing and Roller Chains. New Solid Bushng and Roller Chain now offers up to 30% increase in maximum Allowable Load (MAl) compared to other competitors.
Fundamental Structure of Solid Bushing & Roller Chain
Outsanding longer wear life: Conventional split bushings deform into a barrel shapen when side plates are pressed on, leaving only two-point contact area. Solid Bushing and Roller Chain has extremely cylindrical inside and outside bushing walls resulting in full contact to disperse bearing pressure. Less pressure ensures excellent wear resistance.
Up to 2-3 times longer wear life over curled bushings: The curled, split bushings have a seam where tiny space allows lubricant leakage, resulting in shorter wear life. Solid Bushing and Roller has no seam, resulting in lower bearing pressure, allowing the bushings to retain lubrication and resulting in much longer wear life.
Reliable performance: Solid Bushing Roller is cold-forge froms steel rod. Cold-forming process also works with the molecular structure (grain) of the steel running lengthwise in the bushings thereby increasing fatigue strength, as well as preventing bushings from breakage.Thus, Solid Bushing Roller Chain improves performance of transmission with minimizing elongation for long period of time.
Mechanism of how Solid Bushing & Roller Chain supersedes other competitors for more than 20 years
ANSI Roller Chain: ANSI Roller Chain is standing on JIS B 1801. The uniqueness includes SBR (Solid Bushing & Roller) having no seam on bushing and roller. Thus, it gives it outstanding condition against initial elongation and wear.
Super Roller Chain: Super Roller Chains are an upgrade to a high degree over existing ANSI standard roller chains. Big improvement has been made in particular with fatigue strength and impact absorbing capacity. Super Heavy Roller Chains provide with link plates of next larger chain size prmise you a higher performance and superior quality.
Stainless Steel Roller Chain: These chains are made of SUS300 according to ANSI and BS dimensional specifications. These chains are ideal for highly acidic or alkaline locations, or where the chain will be exposed to water, and for very high or very low temperature locations where resistance to corrosion and to heat is a requirement.
Plated Roller Chain: SENQCIA provides nickel plated and LL (special surface treatment) plated roller chain for higher corrosion resistance than regular ANSI roller chains. Plated roller chains are manufactured for outdoor usage and for situations in which machinery must be run in a lightly corrosive atmosphere or where good chain apprearance may be desired.
HE Series Roller Chain: This series consist of thicker link plate than standard ANSI roller chain and stronger pin with hi streght steel. This creates a higher tensile and fatigue strength, ensuring greater capacity for absorbing shock loads. The HE roller chain is mainly designed for applications where more stronger chains are needed, though space and design are limited.
Heavy Duty Roller Chain: This type of chain is suitable for power transmission in machinery and equipment working under extremely tough load and impact condition such as civil engineering, steel mill (frunace door, draw bench). earth moving & construction equipment, amusement park facilities, and others. Heat treated special steel is used for tmain components, and they are machined to high precision. These are offset type chains. giving them superior impact resistance.
Freedom Series Self-Lubricating Chain: The chain performs well in the application without additional lubrication. Oil impregnated sintered steel bushing provides self-lubricating and it is ideal for the industries that cleanliness is critical such as packaging, printing, food processing, textile and so on. Moreover, it is designed for applications were regular maintenance is not easily accessible.
Lubeless Chain/O-ring Chain: Loss of oil coverage between pins and bushes is one factor controlling the lifespan of a chain. O-ring chains are equipped with O-rings to prevent this loss of oil coverage. Therefore, these chains are suitable for use in situations where it is difficult or impossible to oil the chain, in environments where oiling (lubricant oil) is not tolerated, or in very dusty environments.
Side Bow Chain: In side bow chains, pin-to-bushing clearance is much greater than in standard roller chains and double pitch roller chains. These, together with the clearances between inner and outer links, enable the chain to be used on a curbed trail. Basic dimensions according to JIS enable standard sprockets to be utilized.
BS Standard Roller Chain: Chain made according to UK standards.
