Sintered Bushing Roller Chain (UR/ URN)

Upkeep free chains making use of sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a area the place lubrication is tricky. It uses bushings created of the sintered alloy which impregnates lubricating oil.
For that use that demands clean physical appearance, rustless style (URN) is accessible.
Suggested employs
?Circumstances exactly where lubrication is tricky or elongation of chain regularly takes place Remarks for use.
?Never use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for the use beneath light or medium load.Use O-ring chain whenever a substantial impact is utilized to a chain.
?Set the chain feeding pace at 150m/min. or decrease.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than those of regular roller chains so as to compensate for that strength lowered by the use of sintered bushings.
For deciding on an appropriate chain, refer to “Selection of Chains”. Use the tables of maximum kilowatt ratings for sintered bushing roller chains that cover very low speed ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be utilised since the “Maximum allowable load” during the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting links and offset links
For sintered bushing roller chain, R connecting backlinks are applied for DID60 or smaller sized, and C connecting hyperlinks for DID80 or greater.
OJ is often used as offset links. Please place an buy the connecting hyperlinks and offset backlinks specifying the variety for sintered bushing roller chain.
Within the tables of greatest kilowatt ratings, the power in the connecting back links and offset links are taken into account.
Sprockets
Regular sprockets is usually used for sintered bushing roller chains.
