Maintenance totally free chains working with sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a spot exactly where lubrication is tricky. It makes use of bushings made of the sintered alloy which impregnates lubricating oil.
For the use that necessitates clean visual appeal, rustless type (URN) is accessible.
Advisable uses
?Conditions wherever lubrication is challenging or elongation of chain often takes place Remarks for use.
?Will not use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for that 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 and also the pins are longer than these of common roller chains in order to compensate for your strength lowered through the utilization of sintered bushings.
For picking out an appropriate chain, refer to “Selection of Chains”. Use the tables of optimum kilowatt ratings for sintered bushing roller chains that cover reduced velocity ranges.
For sintered bushing roller chains, “Low-speed selection” are not able to be applied since the “Maximum allowable load” while in the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting back 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 may be applied as offset links. Please area an order the connecting backlinks and offset links specifying the variety for sintered bushing roller chain.
From the tables of highest kilowatt ratings, the strength with the connecting links and offset back links are taken into account.
Sprockets
Regular sprockets can be utilized for sintered bushing roller chains.
