Chuck and Seal

Chuck and Seal

Chuck and seal assemblies are critical accessories in agitation and drive systems, ensuring secure shaft holding, smooth torque transmission, and leak-tight operation in glass reactors and process vessels. These components directly influence mixing efficiency, operational safety, and equipment reliability.

Chuck

A chuck is used to firmly grip the stirrer shaft and transmit rotational motion from the drive unit to the agitator without slippage. It allows quick mounting and removal while maintaining precise shaft alignment.

Construction

• Body material: SS 304 / SS 316
• Precision-machined jaws
• Corrosion-resistant finish
• Compatible with standard drive shafts
