Treadmills are widely used both in home gyms and commercial fitness facilities, but keeping them running smoothly requires proper maintenance. One crucial component of treadmill care is lubrication. The right lubricant will extend the life of your treadmill and ensure that it functions properly over time. However, not all lubricants are created equal, and one key factor to consider is viscosity. In particular, understanding lubricant shear and the advantages of using a higher viscosity lubricant will help prevent common treadmill problems.
