Product Description
MOLYKOTE G-68 Plastic Gear Grease, 4 oz Tube is a 4 oz tube configuration of the mineral-oil/PAO G-68 plastic gear grease grade. The grease uses lithium soap, EP additives, and solid lubricants and has NLGI 2-3 consistency, 75 mm2/s base-oil viscosity at 40 deg C, and a -30 to 140 deg C service range. It can be applied by brush, spatula, grease gun, automatic device, or central lubrication system. Applications include electric toothbrush and paper-shredder gears and related plastic gear mechanisms using the G-68 grade.
Key features
- Plastic Gear Friction Control: The G-68 grade produced a 0.014 steel-ball/POM friction coefficient under the specified test conditions.
- 75 mm2/s Base Oil: The G-68 grade has 75 mm2/s base-oil viscosity at 40 deg C.
- Flexible Grease Application: Supported methods include brush, spatula, grease gun, automatic device, and central lubrication system.
Applications / Suitable for
- Gears in electric toothbrushes.
- Gears in paper shredders.
- Plastic gear mechanisms using the G-68 grade.
