The 91.105.1171 Nylon Gear is a replacement gear assembly for compatible Heidelberg SM102 and CD102 offset printing machines. It is intended for the corresponding geared mechanism, where matching tooth profiles transfer rotary motion between components.
The pictured assembly combines a large nylon gear wheel, a smaller helical gear section and a metal centre hub. These features must match the existing part to ensure correct engagement and fitment within the machine.
Replacement may be required when the fitted gear develops worn, cracked or broken teeth, or damage around its mounting area. Inspecting the mating components during replacement can help identify the cause of wear.
Before ordering, compare the 91.105.1171 reference, tooth count, gear diameters, helical tooth direction, overall length and hub opening with your existing assembly.
Contact Original Offset Parts on WhatsApp with your machine details and clear photographs of the existing gear for compatibility and availability enquiries. Confirm the required quantity when enquiring.
