Sintered Bushing Roller Chain (UR/ URN)

Maintenance free of charge chains applying sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a spot in which lubrication is complicated. It employs bushings made of the sintered alloy which impregnates lubricating oil.
For the use that necessitates clean visual appeal, rustless type (URN) is accessible.
Encouraged uses
?Conditions where lubrication is hard or elongation of chain regularly occurs Remarks for use.
?Don’t 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 large effect is utilized to a chain.
?Set the chain feeding velocity at 150m/min. or decrease.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker as well as the pins are longer than individuals of typical roller chains in order to compensate to the power lowered through the utilization of sintered bushings.
For picking out an appropriate chain, refer to “Selection of Chains”. Use the tables of highest kilowatt ratings for sintered bushing roller chains that cover minimal speed ranges.
For sintered bushing roller chains, “Low-speed selection” are not able to be applied since the “Maximum allowable load” from the dimension table considers only the chain tensile stress and neglects the bushing strength.
Connecting links and offset backlinks
For sintered bushing roller chain, R connecting back links are employed for DID60 or smaller, and C connecting back links for DID80 or larger.
OJ could be made use of as offset hyperlinks. Please area an purchase the connecting backlinks and offset links specifying the form for sintered bushing roller chain.
During the tables of greatest kilowatt ratings, the strength of your connecting hyperlinks and offset back links are taken into account.
Sprockets
Regular sprockets may be employed for sintered bushing roller chains.
