Upkeep free chains applying sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a spot exactly where lubrication is challenging. It makes use of bushings manufactured of the sintered alloy which impregnates lubricating oil.
For your use that demands clean appearance, rustless type (URN) is available.
Proposed uses
?Circumstances in which lubrication is difficult or elongation of chain frequently happens Remarks for use.
?Don’t use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for the use beneath light or medium load.Use O-ring chain when a substantial effect is applied to a chain.
?Set the chain feeding speed at 150m/min. or reduce.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than these of common roller chains in order to compensate for the strength lowered by the utilization of sintered bushings.
For deciding on an appropriate chain, refer to “Selection of Chains”. Make use of the tables of greatest kilowatt ratings for sintered bushing roller chains that cover minimal velocity ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be employed since the “Maximum allowable load” within the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting hyperlinks and offset back links
For sintered bushing roller chain, R connecting backlinks are applied for DID60 or smaller sized, and C connecting back links for DID80 or more substantial.
OJ may be employed as offset backlinks. Please area an buy the connecting hyperlinks and offset links specifying the variety for sintered bushing roller chain.
During the tables of highest kilowatt ratings, the power of 
the connecting links and offset back links are taken into consideration.
Sprockets
Common sprockets might be employed for sintered bushing roller chains.
