This is the replacement walking belt for the Proform 650 V treadmill. Model number PETL77905 R0. POLYESTER-BLENDED BACKING: The Treadmill Doctor treadmill walking mats are 2-ply belts with a durable PVC top coat and polyester-blended backing. This reduces the risk of damage to electrical components, common with thicker and less pliable walking belts. PRE-LUBRICATED: The treadmill walking belt by Treadmill Doctor has been pre-lubricated and includes an additional application of lube. It is recommended to lubricate your walking belt at least once a year to reduce friction and stress on the other components of your treadmill.
