Maintenance absolutely free chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a spot where lubrication is tough. It utilizes bushings manufactured of a sintered alloy which impregnates lubricating oil.
For that use that needs clean visual appeal, rustless kind (URN) is obtainable.
Proposed employs
?Circumstances wherever lubrication is tough or elongation of chain frequently occurs Remarks for use.
?Do not use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for your use underneath light or medium load.Use O-ring chain when a big influence is applied to a chain.
?Set the chain feeding velocity at 150m/min. or decrease.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker as well as the pins are longer than those of standard roller chains so as to compensate to the strength lowered by the utilization of sintered bushings.
For selecting an appropriate chain, refer to “Selection of Chains”. Use the tables of greatest kilowatt ratings for sintered bushing roller chains that cover very low speed ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be made use of because the “Maximum allowable load” within the dimension table considers only the chain tensile stress and neglects the bushing strength.
Connecting back links and offset hyperlinks
For sintered bushing roller chain, R connecting back links are utilised for DID60 or smaller, and C connecting links for DID80 or more substantial.
OJ may be used as offset back links. Please place an purchase the connecting links and offset links specifying the form for sintered bushing roller chain.
From the tables of optimum kilowatt ratings, the power with the connecting hyperlinks and offset backlinks are taken into account.
Typical sprockets can be utilized for sintered bushing roller chains.
