Servicing free of charge chains working with sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a area where lubrication is difficult. It employs bushings produced of the sintered alloy which impregnates lubricating oil.
To the use that demands clean visual appeal, rustless style (URN) is accessible.
Proposed employs
?Circumstances in which lubrication is complicated or elongation of chain frequently takes place Remarks for use.
?Never use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is to the use beneath light or medium load.Use O-ring chain when a substantial impact is utilized to a chain.
?Set the chain feeding velocity at 150m/min. or reduce.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than people of regular roller chains in order to compensate to the strength lowered from the use of sintered bushings.
For choosing an appropriate chain, refer to “Selection of Chains”. Utilize the tables of maximum kilowatt ratings for sintered bushing roller chains that cover lower pace ranges.
For sintered bushing roller chains, “Low-speed selection” can not be used because the “Maximum allowable load” inside the dimension table considers only the chain tensile stress and neglects the bushing strength.
Connecting backlinks and offset backlinks
For sintered bushing roller chain, R connecting back links are utilised for DID60 or smaller, and C connecting hyperlinks for DID80 or bigger.
OJ could be employed as offset back links. Please place an order the connecting backlinks and offset back links specifying the style for sintered bushing roller chain.
Within the tables of optimum kilowatt ratings, the strength from the connecting backlinks and offset links are taken under consideration.
Common sprockets may be utilized for sintered bushing roller chains.
