We offer on the list of most substantial lines of specialty Maintenance Free of charge roller chain items offered to fi t a wide array of exclusive application wants. Designers can pick out the series that finest fi ts the distinct wants with the application. These chains must be specifi ed only when situations prohibit the usage of lubricating oil considering the fact that, normally, a effectively lubricated regular chain will off er longer life in contrast which has a maintenance free of charge chain. In some applications however lubrication isn?¡¥t achievable and so the use of a self lubricated or sealed roller chain is necessary.
Standard 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 as a result of friction developed amongst the pin and bushing as the chain articulates over the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which may hold a higher volume of oil.
PT Variety Roller Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction created among 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 hyperlink plates are one particular size thicker to increase power. Side plates and pins have specific 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 Sort but better compared to the SL form. Attachments with common dimen-sions can be used for this series and hence they’re normally utilised on smaller material dealing with conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains employ a rubber seal to keep lubricating grease in even though avoiding the penetration of grime along with other contaminants to the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains employ a stainless steel seal to help keep lubricating grease in when stopping the penetration of grime and other contaminants in to the pin/bushing bearing place.
