We offer among the list of most in depth lines of specialty Maintenance Absolutely free roller chain solutions accessible to fi t a broad array of special application desires. Designers can select the series that ideal fi ts the particular demands with the application. These chains must be specifi ed only when circumstances prohibit using lubricating oil since, usually, a well lubricated standard chain will off er longer life compared by using a servicing free chain.

General Properties of Maintenance Absolutely free Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction created concerning the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains are rollerless and consequently use thick sectioned powdered metal bushings which could hold a large volume of oil.
PT Form Roller Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint due to the friction designed amongst the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller website link plates are one dimension thicker to increase strength. Side plates and pins have distinctive coatings to avoid rust.
C-Type Roller Chains
Same as over except the side plates are all conventional thickness. The strength of your CS Style chains is lower than the PT Variety but greater than the SL variety. Attachments with standard dimen-sions can be utilized for this series and thus they can be normally used on compact materials managing conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to help keep lubricating grease in while preventing the penetration of grime along with other contaminants in to the pin/bush-ing bearing place.
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 even though preventing the penetration of grime as well as other contaminants in to the pin/bushing bearing area.
