We offer one of many most substantial lines of specialty Maintenance Free roller chain products readily available to fi t a wide array of special application requirements. Designers can pick the series that greatest fi ts the specific desires from the application. These chains need to be specifi ed only when situations prohibit the usage of lubricating oil because, on the whole, a effectively lubricated normal chain will off er longer existence in contrast using a upkeep totally free chain. In some applications having said that lubrication isn?¡¥t achievable and so using a self lubricated or sealed roller chain is necessary.
Common Properties of Maintenance Free of charge Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint as a result of friction produced among the pin and bushing as the chain articulates above the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which can hold a higher volume of oil.
PT Style Roller Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction created in between the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller link plates are 1 size thicker to improve strength. Side plates and pins have particular coatings to avoid rust.
C-Type Roller Chains
Exact same as above except the side plates are all common thickness. The power with the CS Form chains is under the PT Variety but higher compared to the SL type. Attachments with normal dimen-sions can be used for this series and as a result these are generally utilised on small material handling conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains use a rubber seal to help keep lubricating grease in while stopping the penetration of grime and various contaminants into the pin/bush-ing bearing location.
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 when preventing the penetration of dirt together with other contaminants in to the pin/bushing bearing spot.
