Standard Data
We offer one of several most intensive lines of specialty Maintenance Free of charge roller chain merchandise offered to fi t a broad array of unique application needs. Designers can decide on the series that finest fi ts the specific desires with the application. These chains need to be specifi ed only when conditions prohibit the usage of lubricating oil considering that, normally, a effectively lubricated common chain will off er longer life compared using a servicing totally free chain. In some applications however lubrication isn?¡¥t achievable and so the usage of a self lubricated or sealed roller chain is critical.
Common Properties of Servicing Totally free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint because of the friction produced concerning the pin and bushing because the chain articulates more than the sprocket teeth. These chains are rollerless and consequently use thick sectioned powdered metal bushings which might 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 designed involving the pin and bushing as the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller hyperlink plates are one size thicker to improve strength. Side plates and pins have specific coatings to stop rust.
C-Type Roller Chains
Similar as above except the side plates are all common thickness. The power of your CS Style chains is less than the PT Sort but better compared to the SL style. Attachments with standard dimen-sions can be utilized for this series and hence they are really often utilised on smaller material handling conveyors.
P-Ring Chains
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to help keep lubricating grease in even though stopping the penetration of filth along with other contaminants in to the pin/bush-ing 
bearing spot.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains make use of a stainless steel seal to help keep lubricating grease in when stopping the penetration of grime along with other contaminants to the pin/bushing bearing location.
