We offer among the most substantial lines of specialty Upkeep Cost-free roller chain items out there to fi t a wide array of special application desires. Designers can opt for the series that greatest fi ts the individual desires in the application. These chains really should be specifi ed only when conditions prohibit the usage of lubricating oil considering that, generally, a well lubricated common chain will off er longer life compared by using a maintenance cost-free chain. In some applications nevertheless lubrication isn?¡¥t achievable and so using a self lubricated or sealed roller chain is critical.
Basic Properties of Upkeep Absolutely free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction developed in between the pin and bushing as the chain articulates more than the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which might hold a high volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction produced concerning the pin and bushing as the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller hyperlink plates are 1 size thicker to improve power. Side plates and pins have distinctive coatings to avoid rust.
C-Type Roller Chains
Similar as over except the side plates are all typical thickness. The strength on the CS Sort chains is under the PT Style but better compared to the SL kind. Attachments with common dimen-sions can be utilized for this series and thus these are generally utilized on smaller materials handling conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to maintain lubricating grease in when stopping the penetration of filth along with other contaminants in to the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains employ a stainless steel seal to help keep lubricating grease in when preventing the penetration of filth and various contaminants to the pin/bushing bearing area.
