In this case, it is necessary to apply lubricant to the joints between the components to improve lubrication and extend their service life. The viscosity of the lubricant is one of the key factors affecting its impact resistance. High-viscosity lubricants can form thicker oil films between mechanical components, providing better lubrication and protection.
