We offer among the list of most in depth lines of specialty Maintenance Cost-free roller chain goods obtainable to fi t a wide array of exclusive application requirements. Designers can pick out the series that most effective fi ts the distinct requirements with the application. These chains must be specifi ed only when situations prohibit the usage of lubricating oil due to the fact, normally, a effectively lubricated regular chain will off er longer life in contrast which has a maintenance absolutely free chain. In some applications however lubrication isn?¡¥t doable and so the use of a self lubricated or sealed roller chain is critical.
Basic Properties of Upkeep Free of charge Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint because of the friction developed involving the pin and bushing since the chain articulates over the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which can hold a large volume of oil.
PT Variety Roller Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint as a result of friction developed amongst the pin and bushing as the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller website link plates are one particular size thicker to boost strength. Side plates and pins have exclusive coatings to avoid rust.
C-Type Roller Chains
Very same as over except the side plates are all common thickness. The strength on the CS Type chains is lower than the PT Kind but higher compared to the SL form. Attachments with common dimen-sions can be used for this series and as a result they’re normally made use of on modest material managing conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains employ a rubber seal to keep lubricating grease in when avoiding the penetration of grime as well as other contaminants to the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains use a stainless steel seal to help keep lubricating grease in when stopping the penetration of grime and other contaminants to the pin/bushing bearing spot.
