We offer one of many most considerable lines of specialty Maintenance Totally free roller chain items offered to fi t a broad array of specific application requires. Designers can select the series that best fi ts the unique wants on the application. These chains need to be specifi ed only when situations prohibit the usage of lubricating oil due to the fact, on the whole, a effectively lubricated typical chain will off er longer life compared that has a servicing free chain. In some applications even so lubrication isn?¡¥t possible and so the usage of a self lubricated or sealed roller chain is necessary.
Common Properties of Servicing Free of charge Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint as a result of friction produced between the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which could hold a high volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction formulated between the pin and bushing because the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller link plates are a single dimension thicker to increase strength. Side plates and pins have special coatings to avoid rust.
C-Type Roller Chains
Very same as over except the side plates are all typical thickness. The strength on the CS Form chains is less than the PT Variety but higher compared to the SL variety. Attachments with typical dimen-sions can be utilized for this series and thus they can be frequently used on smaller materials managing conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains use a rubber seal to maintain lubricating grease in while avoiding the penetration of filth along with other contaminants in to the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains make use of a stainless steel seal to maintain lubricating grease in although avoiding the penetration of grime together with other contaminants to the pin/bushing bearing spot.
