General Data
We offer on the list of most in depth lines of specialty Servicing No cost roller chain merchandise available to fi t a wide array of specific application requirements. Designers can pick the series that ideal fi ts the certain desires of the application. These chains should be specifi ed only when situations prohibit the usage of lubricating oil considering that, in general, a properly lubricated regular chain will off er longer existence compared using a servicing no cost chain. In some applications on the other hand lubrication isn?¡¥t feasible and so the use of a self lubricated or sealed roller chain 
is necessary.
General Properties of Maintenance No cost Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint because of the friction developed involving the pin and bushing as the chain articulates over the sprocket teeth. These chains are rollerless and therefore use thick sectioned powdered metal bushings which can hold a large volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint because of the friction created between the pin and bushing because the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller hyperlink plates are a single size thicker to increase strength. Side plates and pins have exclusive coatings to prevent rust.
C-Type Roller Chains
Very same as over except that the side plates are all conventional thickness. The strength of your CS Type chains is lower than the PT Kind but greater than the SL sort. Attachments with normal dimen-sions may be used for this series and therefore these are normally applied on compact material dealing with conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains employ a rubber seal to maintain lubricating grease in while preventing the penetration of grime and various contaminants into the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains employ a stainless steel seal to maintain lubricating grease in although stopping the penetration of grime along with other contaminants in to the pin/bushing bearing region.
