Maintenance no cost chains working with sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a area the place lubrication is difficult. It uses bushings manufactured of the sintered alloy which impregnates lubricating oil.
To the use that needs clean visual appeal, rustless kind (URN) is accessible.
Encouraged utilizes
?Conditions in which lubrication is hard or elongation of chain frequently takes place Remarks for use.
?Will not use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for the use under light or medium load.Use O-ring chain when a significant influence is applied to a chain.
?Set the chain feeding pace at 150m/min. or reduced.
Collection of chains
As for sintered bushing roller chains, the inner plates are thicker as well as pins are longer than these of normal roller chains so as to compensate for that power lowered by the utilization of sintered bushings.
For picking out a suitable chain, refer to “Selection of Chains”. Make use of the tables of highest kilowatt ratings for sintered bushing roller 
chains that cover reduced velocity ranges.
For sintered bushing roller chains, “Low-speed selection” cannot be used since the “Maximum allowable load” within the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting back links and offset hyperlinks
For sintered bushing roller chain, R connecting backlinks are applied for DID60 or smaller, and C connecting links for DID80 or larger.
OJ can be employed as offset back links. Please spot an order the connecting back links and offset links specifying the sort for sintered bushing roller chain.
During the tables of maximum kilowatt ratings, the strength on the connecting back links and offset links are taken under consideration.
Sprockets
Typical sprockets may be utilised for sintered bushing roller chains.
