Fully sealed type | 3-Jaw Lathe Chuck

  • Fully sealed design extends maintenance intervals, improving production efficiency.
  • 3 jaw lathe chuck with sealed design ensures constant lubrication and protects against the ingress of coolant and chips, which guarantees clamping precision and durability.
  • Suitable for lights-out manufacturing; dry machining of castings and forgings; or when high-pressure coolant is utilized. Especially ideal for vertical lathes.
  • Media fed through central bore – available for coolant or air (optional).
