This pre-lubed Sportsmith walking belt fits Smooth Fitness 5.0P treadmills*.  If it's minimal maintenance you want, this PVC belt with impregnated lubrication requires less attention to make things run smoothly.  All Sportsmith belts feature components that make the best when it comes to quality and performance.  A top feature of Sportsmith belts is the non-directional, finger splice seam.  This means you can install the belt in either direction.
