We offer among the list of most comprehensive lines of specialty Servicing Cost-free roller chain products readily available to fi t a broad array of special application requires. Designers can select the series that ideal fi ts the individual requires of the application. These chains ought to be specifi ed only when situations prohibit the usage of lubricating oil since, in general, a properly lubricated conventional chain will off er longer lifestyle compared having a servicing absolutely free chain. In some applications on the other hand lubrication isn?¡¥t doable and so using a self lubricated or sealed roller chain is critical.
Basic Properties of Servicing Free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction designed involving the pin and bushing because the chain articulates over the sprocket teeth. These chains are rollerless and as a result 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 due to the friction formulated involving the pin and bushing since the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller website link plates are a single dimension thicker to increase strength. Side plates and pins have particular coatings to prevent rust.
C-Type Roller Chains
Identical as above except that the side plates are all typical thickness. The strength with the CS Form chains is lower than the PT Type but better than the SL type. Attachments with regular dimen-sions can be utilized for this series and therefore they can be normally made use of on little material dealing with conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains use a rubber seal to keep lubricating grease in although preventing the penetration of dirt and also other contaminants to the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains utilize a stainless steel seal to keep lubricating grease in while preventing the penetration of filth together with other contaminants to the pin/bushing bearing location.
