General Info
We offer among the list of most extensive lines of specialty Maintenance Free of charge roller chain items obtainable to fi t a wide array of exclusive application needs. Designers can pick out the series that ideal fi ts the specific requirements with the application. These chains ought to be specifi ed only when situations prohibit the usage of lubricating oil considering that, generally, a effectively lubricated conventional chain will off er longer daily life in contrast that has a servicing free of charge chain. In some applications on the other hand lubrication isn?¡¥t achievable and so using a self lubricated or sealed roller chain is necessary.
Basic Properties of Maintenance Free of charge Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint because of the friction formulated among the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains are rollerless and consequently use thick sectioned powdered metal bushings which could hold a higher volume of oil.
PT Variety Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction formulated among the pin and bushing as the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller hyperlink plates are a single size thicker to increase power. Side plates and pins have specific coatings to stop rust.
C-Type Roller Chains
Identical as above except the side plates are all regular thickness. The strength on the CS Style chains is lower than the PT Sort but higher than the SL variety. Attachments with normal dimen-sions may be used for this series and hence they are really normally utilised on tiny materials dealing with conveyors.
P-Ring Chains
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to maintain lubricating grease in even though stopping the penetration of dirt as well as other contaminants to the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains employ a stainless steel seal to keep lubricating grease in when preventing the penetration of grime together with other contaminants in to the pin/bushing bearing location.
