Sintered Bushing Roller Chain (UR/ URN)

Maintenance totally free chains working with sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a location exactly where lubrication is hard. It makes use of bushings made of a sintered alloy which impregnates lubricating oil.
For that use that involves clean physical appearance, rustless style (URN) is available.
Advisable employs
?Conditions wherever lubrication is challenging or elongation of chain often takes place Remarks for use.
?Will not use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for that use underneath light or medium load.Use O-ring chain when a significant effect is utilized to a chain.
?Set the chain feeding velocity at 150m/min. or reduced.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than these of normal roller chains in order to compensate for your strength lowered from the utilization of sintered bushings.
For deciding on 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” can not be utilised 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 utilized for DID60 or smaller, and C connecting back links for DID80 or more substantial.
OJ may be applied as offset links. Please spot an order the connecting backlinks and offset links specifying the variety for sintered bushing roller chain.
From the tables of highest kilowatt ratings, the power on the connecting links and offset back links are taken under consideration.
Sprockets
Standard sprockets can be utilized for sintered bushing roller chains.
