We offer on the list of most comprehensive lines of specialty Upkeep Cost-free roller chain products readily available to fi t a wide array of exclusive application desires. Designers can pick out the series that finest fi ts the specific desires from the application. These chains should be specifi ed only when conditions prohibit using lubricating oil since, usually, a properly lubricated standard chain will off er longer life in contrast which has a upkeep free of charge chain. In some applications having said that lubrication isn?¡¥t feasible and so the usage of a self lubricated or sealed roller chain is important.
Common Properties of Servicing Cost-free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction formulated involving the pin and bushing as the chain articulates over the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which could hold a higher volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction designed concerning the pin and bushing because the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller website link plates are a single size thicker to boost power. Side plates and pins have unique coatings to stop rust.
C-Type Roller Chains
Identical as above except the side plates are all standard thickness. The strength of the CS Kind chains is under the PT Form but better than the SL form. Attachments with typical dimen-sions can be used for this series and thus they're often employed on smaller materials handling conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains utilize a rubber seal to help keep lubricating grease in though preventing the penetration of dirt and also other contaminants to the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains use a stainless steel seal to keep lubricating grease in even though stopping the penetration of dirt together with other contaminants into the pin/bushing bearing place.
