Kluber Nontrop KR 291 - Chuck Grease for Constant Clamping Force (1kg)

Precision & Safety in Machining Starts Here: The Secret to Constant Clamping Force

In high-precision machining, few things are more critical—or more overlooked—than consistent chuck clamping force. A gradual loss of this force due to inadequate lubrication can lead to vibration, chatter, poor surface finish, and even catastrophic workpiece ejection. This isn't just a maintenance issue; it's a safety and quality imperative.

Kluber Nontrop KR 291 is not just another grease; it is a specialized lubricating paste engineered in Germany specifically to master this challenge. As the leading Chuck Grease for Clamping Force, its primary function is to maintain a consistent coefficient of friction in the chuck mechanism, ensuring your clamping force remains constant from the first part to the last. This High Adhesion Paste is your best defense against the variables that compromise quality and safety.

Key Features & Benefits:

• Ensures Constant Clamping Force: Its specialized formula provides a stable friction coefficient, which is critical for maintaining the intended clamping force of power chucks, leading to improved machining accuracy and repeatability.

• Exceptional Adhesion & Coolant Resistance: The paste strongly adheres to metal surfaces, resisting washout from high-pressure coolants and metalworking fluids. This prevents lubricant starvation and ensures continuous protection.

• Superior Wear and Corrosion Protection: Forms a durable, pressure-resistant lubricating film that protects chuck jaws, wedges, and other internal components from fretting corrosion and excessive wear, significantly extending the life of your expensive chuck.

• Good Sealing Effect: Helps to seal the chuck mechanism, preventing the ingress of contaminants like chips and dirt that can accelerate wear and cause malfunction.

Primary Applications:

Kluber Nontrop KR 291 is the industry standard for the lubrication of:

• Power Chucks and Manual Lathe Chucks: For all friction points within the chuck body, including jaws, wedges, and scroll mechanisms.

• Clamping Jaws & Workholding Fixtures: Ensures smooth movement and reliable clamping force in all types of workholding systems.

• Sliding Guides & Spindles: Can also be used for other machine tool components requiring high adhesion and wear protection.

Don't let inconsistent lubrication compromise your workshop's precision and safety. Investing in Kluber Nontrop KR 291 is a direct investment in part quality, operational reliability, and peace of mind.Kluber Nontrop KR 291Chuck Grease for Clamping ForceCoolant Resistant Paste
