We offer among the most substantial lines of specialty Servicing No cost roller chain items obtainable to fi t a wide array of particular application demands. Designers can opt for the series that ideal fi ts the particular requirements from the application. These chains ought to be specifi ed only when situations prohibit using lubricating oil considering the fact that, in general, a properly lubricated conventional chain will off er longer daily life compared having a upkeep totally free chain. In some applications even so lubrication isn?¡¥t probable and so using a self lubricated or sealed roller chain is critical.
General Properties of Maintenance Cost-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 between the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which may hold a large volume of oil.
PT Form Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint as a result of friction created involving the pin and bushing as the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller link plates are one dimension thicker to increase power. Side plates and pins have particular coatings to stop rust.
C-Type Roller Chains
Very same as over except the side plates are all standard thickness. The strength on the CS Variety chains is under the PT Kind but greater compared to the SL form. Attachments with normal dimen-sions can be utilized for this series and so they are normally employed on tiny material handling conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains utilize a rubber seal to keep lubricating grease in although avoiding the penetration of dirt as well as other contaminants in to the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains utilize a stainless steel seal to maintain lubricating grease in whilst avoiding the penetration of filth along with other contaminants into the pin/bushing bearing spot.
