General Properties of Servicing Free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction produced in between the pin and bushing since the chain articulates over the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which might hold a higher volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint due to the friction created amongst the pin and bushing because the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller website link plates are one particular size thicker to boost power. Side plates and pins have particular coatings to avoid rust.
C-Type Roller Chains
Identical as over except that the side plates are all typical thickness. The strength in the CS Kind chains is under the PT Sort but better than the SL form. Attachments with typical dimen-sions may be used for this series and so they’re typically applied on smaller materials dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to maintain lubricating grease in even though stopping the penetration of filth and other contaminants to the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on bigger 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 and also other contaminants to the pin/bushing bearing region.
