Upkeep free chains applying sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a spot where lubrication is tough. It makes use of bushings manufactured of the sintered alloy which impregnates lubricating oil.
For the use that requires clean appearance, rustless type (URN) is available.
Proposed uses
?Circumstances in which lubrication is difficult or elongation of chain commonly occurs Remarks for use.
?Don’t use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for the use below light or medium load.Use O-ring chain when a massive effect is applied to a chain.
?Set the chain feeding speed at 150m/min. or reduce.
Selection 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 power lowered through the use 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 reduced velocity ranges.
For sintered bushing roller chains, “Low-speed selection” cannot be employed since the “Maximum allowable load” in 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 hyperlinks are utilised for DID60 or smaller sized, and C connecting backlinks for DID80 or more substantial.
OJ may be utilized as offset backlinks. Please spot an buy the connecting hyperlinks and offset back links specifying the variety for sintered bushing roller chain.
During the tables of optimum kilowatt ratings, the power of your connecting links and offset back links are taken into consideration.
Normal sprockets could be employed for sintered bushing roller chains.
