Jason Industrial SPZ850 metric cogged V-belt, SPZ section, 850mm outside length, 9.7mm top width, 8mm thickness. Cogged design provides flexibility and reduced bending stress for compact high-power industrial drives. Neoprene body with polyester tension cord and fabric cover for durability.

Oil and heat-resistant. Static dissipating.Built to European standards DIN 7753 AFNOR T47-117 BS 3790 and ISO 4184. SP series V-belts were the forerunners of the RMA deep wedge high capacity V-belt sections. These deep-wedge belts (38) allow for more power high speed ratios smaller center distances and more compact drives. They are replacement belts for many imported machines and for machinery built for export. These V-belts also have the UniMatch feature. This eliminates belt set matching with its multiple stocking problems Metric V-belts are specified by letters showing the SP section and numbers giving the pitch length in millimeters. For example: SPA 850.NOTE : Belt sizes to 2240 mm in length are also available in raw edge construction. These belts are designated by an X prefix rather than S. For example: XPB1400. For Raw Edge Construction add 25- to list price. Although metric V-belts are ordered by section and pitch length they are sometimes labeled with the section letters belt length in millimeters and the letters LA (approx. length) LI (inside length) or LW (pitch length). Add 13 mm to pitch length for outside length. For notched construction add 25- to the list price.
