Standard Info
We offer on the list of most considerable lines of specialty Upkeep Cost-free roller chain products accessible to fi t a broad array of special application wants. Designers can choose the series that ideal fi ts the individual needs of your application. These chains really should be specifi ed only when conditions prohibit the use of lubricating oil considering the fact that, normally, a well lubricated regular chain will off er longer lifestyle compared by using a servicing no cost chain. In some applications nonetheless lubrication isn?¡¥t achievable and so the usage of a self lubricated or sealed roller chain is necessary.
Basic 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 designed amongst the pin and bushing as the chain articulates over the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which can hold a high volume of oil.
PT Style Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction produced concerning the pin and bushing since the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller link plates are one particular size thicker to increase power. Side plates and pins have unique coatings to prevent rust.
C-Type Roller Chains
Same as above except that the side plates are all standard thickness. The strength on the CS Kind chains is less than the PT Style but higher than the SL variety. Attachments with conventional dimen-sions can be used for this series and consequently they are normally made use of on tiny material handling conveyors.
P-Ring Chains
Specifi ed on smaller pitch roller chains O-Ring chains make use of a rubber 
seal to keep lubricating grease in when preventing the penetration of grime together with other contaminants to the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains make use of a stainless steel seal to help keep lubricating grease in when avoiding the penetration of dirt and various contaminants in to the pin/bushing bearing place.
