Sintered Bushing Roller Chain (UR/ URN)

Servicing no cost chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a place in which lubrication is complicated. It uses bushings made of a sintered alloy which impregnates lubricating oil.
To the use that calls for clean appearance, rustless kind (URN) is obtainable.
Proposed utilizes
?Situations exactly where lubrication is complicated or elongation of chain usually takes place Remarks for use.
?Never use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is to the use beneath light or medium load.Use O-ring chain whenever 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 along with the pins are longer than those of typical roller chains in order to compensate for the power lowered from the use of sintered bushings.
For picking out an appropriate chain, refer to “Selection of Chains”. Utilize the tables of maximum kilowatt ratings for sintered bushing roller chains that cover very low velocity ranges.
For sintered bushing roller chains, “Low-speed selection” can not be utilised since the “Maximum allowable load” within the dimension table considers only the chain tensile stress and neglects the bushing strength.
Connecting hyperlinks and offset links
For sintered bushing roller chain, R connecting hyperlinks are made use of for DID60 or smaller, and C connecting back links for DID80 or more substantial.
OJ is often used as offset back links. Please location an order the connecting hyperlinks and offset hyperlinks specifying the sort for sintered bushing roller chain.
While in the tables of greatest kilowatt ratings, the power from the connecting hyperlinks and offset backlinks are taken under consideration.
Common sprockets may be employed for sintered bushing roller chains.
