Sintered Bushing Roller Chain (UR/ URN)

Maintenance free chains employing 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 manufactured 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 tough 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 influence is utilized to a chain.
?Set the chain feeding velocity at 150m/min. or reduced.
Collection 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 low velocity ranges.
For sintered bushing roller chains, “Low-speed selection” can not be utilised because 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 hyperlinks
For sintered bushing roller chain, R connecting backlinks are utilized for DID60 or smaller, and C connecting backlinks for DID80 or more substantial.
OJ can be applied as offset links. Please spot an order the connecting hyperlinks and offset back links specifying the sort for sintered bushing roller chain.
From the tables of highest kilowatt ratings, the power on the connecting links and offset backlinks are taken under consideration.
Standard sprockets is usually utilized for sintered bushing roller chains.
