Specialty Roller ChainsPin Gear Attachment ChainBefore Use For Safe UseStandard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingFor straight drive and large-radius turning operations, a chain gear is used by the drivesource (motor, etc.) through a reducer. This can result in cost issues and so on, as thechain requires a great deal of space, and precision processing is required for the gears.Pin Gears are perfect in this situation.An Attachment Chain is used around the outside of the drum in place of a gear drivewheel, and a specially-processed sprocket is used for the pinion gear. For linear operation,an Attachment Chain is installed horizontally in place of the rack. Be sure to use heattreatedinstallation bolts.
