Common Facts
We offer among the most comprehensive lines of specialty Maintenance Absolutely free roller chain products accessible to fi t a wide array of special application requires. Designers can select the series that very best fi ts the distinct requirements on the application. These chains must be specifi ed only when situations prohibit using lubricating oil since, in general, a effectively lubricated common chain will off er longer existence compared which has a upkeep absolutely free chain. In some applications nevertheless lubrication isn?¡¥t achievable and so using a self lubricated or sealed roller chain is important.
Standard Properties of Upkeep Totally free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction developed concerning the pin and bushing as the chain articulates above the sprocket teeth. These chains are rollerless and therefore use thick sectioned powdered metal bushings which could hold a high volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint due to the friction designed in between 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 a single size thicker to increase strength. Side plates and pins have exclusive coatings to stop rust.
C-Type Roller Chains
Exact same as above except the side plates are all normal thickness. The power of the CS Kind chains is under the PT Kind but greater than the SL variety. Attachments with normal dimen-sions can be used for this series and therefore they can be typically made use of on tiny materials managing conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains utilize a rubber seal to keep lubricating grease in although avoiding the penetration of filth and other contaminants into the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains utilize a stainless steel seal to help keep lubricating grease in when preventing the penetration of dirt together with other contaminants in to the pin/bushing bearing spot.
