Common Properties of Servicing Totally free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint because of the friction produced in between the pin and bushing since the chain articulates more than the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which could hold a large volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint because of the friction created amongst the pin and bushing since the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are one dimension thicker to improve strength. Side plates and pins have exclusive coatings to prevent rust.
C-Type Roller Chains
Very same as above except that the side plates are all typical thickness. The strength in the CS Kind chains is under the PT Variety but greater compared to the SL style. Attachments with standard dimen-sions may be used for this series and therefore they can be typically made use of on compact material dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to keep lubricating grease in when avoiding the penetration of dirt along with other contaminants into the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains use a stainless steel seal to maintain lubricating grease in when stopping the penetration of grime and also other contaminants into the pin/bushing bearing spot.
