THK Manual Grease Gun, 70 g

The THK MG70 is a manual grease‑gun unit designed for use with 70 g (or 80 g) bellows‑type grease cartridges and small‑form lubrication points. It delivers a maximum discharge pressure of 19.6 MPa and a stroke rate of approximately 0.6 cm³ per actuation. The bellows system provides cleaner handling than traditional cartridge guns. Its compact length and nozzle compatibility with multiple attachments (Types U, N, P, L, H) enable access to confined lubrication points.

Notable Advantages of the THK MG70 Grease Gun

• Bellows‑cartridge design supports 70 g or 80 g grease supplies.
• Max discharge pressure of 19.6 MPa enables lubrication under moderately high loads.
• Stroke output of 0.6 cm³ per actuation ensures controlled grease delivery.
• Slit‑window allows monitoring of the grease remaining in the cartridge.
• Compact overall length (~235 mm excluding nozzle) supports access in tight machine environments.
• Designed for integration with LM guides, ball screws and other precision motion components.

Engineered for Precision Lubrication

The MG70 is purpose‑built for industrial maintenance of linear‑motion systems and other high‑precision assemblies where correct lubrication is critical. The high‑pressure rating ensures the grease can reach tight tolerances and bearing seats.

Usage Scenarios of the Product

• Lubrication of LM Guide rails, blocks and carriages in automation systems.
• Maintenance of ball‑screws and support bearings in precision machine tools.
• OEM assembly lines where compact manual lubrication tools are required.
• Service and repair shops that support linear‑motion equipment with critical lubrication needs.
• Situations requiring clean, controlled grease application in restricted spaces.
