Sintered Bushing Roller Chain (UR/ URN)

Upkeep free chains working with sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a place where lubrication is difficult. It makes use of bushings made of the sintered alloy which impregnates lubricating oil.
For your use that demands clean appearance, rustless sort (URN) is available.
Recommended utilizes
?Situations exactly where lubrication is tough or elongation of chain commonly takes place Remarks for use.
?Don’t use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for that use under light or medium load.Use O-ring chain whenever a large affect is utilized to a chain.
?Set the chain feeding pace at 150m/min. or lower.
Selection of chains
As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than these of normal roller chains so as to compensate for the power lowered through the utilization of sintered bushings.
For picking out a suitable chain, refer to “Selection of Chains”. Use the tables of highest kilowatt ratings for sintered bushing roller chains that cover lower velocity ranges.
For sintered bushing roller chains, “Low-speed selection” cannot be made use of because the “Maximum allowable load” during the dimension table considers only the chain tensile tension and neglects the bushing power.
Connecting back links and offset back links
For sintered bushing roller chain, R connecting backlinks are utilized for DID60 or smaller, and C connecting hyperlinks for DID80 or bigger.
OJ might be utilized as offset links. Please place an buy the connecting links and offset links specifying the sort for sintered bushing roller chain.
Inside the tables of optimum kilowatt ratings, the strength with the connecting links and offset back links are taken into consideration.
Sprockets
Regular sprockets could be applied for sintered bushing roller chains.
