These cartridge spindles have been developed under the German standard DIN 69002 and quickly became very popular among machine tool builders and users. Some of the benefits of these spindles are listed below:

• Easy mounting and dismounting.
• Interchangeability of various cartridges comprised of different bearings configurations and preloads.
• Bearings are lubricated for life. No maintenance re-lubrication needed.
• Non-contact labyrinth seal with air purge.
• Zero backlash ROTEX coupling that compensates for axial, angular and parallel misalignment.

Colonial has provided the machine tool industry with many of these cartridge spindles.

They are very reliable, extremely reasonably priced and have short deliveries. We can always provide alternate designs such as:

• HSK tooling interface based on EPB or Guhring. (Mapal is the standard choice).
• Specific bearing configuration and preload.
