Flat Wire Mesh Belt Sprocket 304 Stainless Steel 1"X1"

The Keystone Sprocket is available in cast iron, UHMW and stainless steel 1"x1" flat wire mesh belt sprocket used commonly on industrial ovens and washers. Replace your worn conveyor sprockets, which may be causing tooth jumping or belt tracking issues in your process equipment.

Sprocket Driven systems provide a positive drive of the belt and help maintain belt alignment. Sprockets systems are generally lower cost than pulley drive systems. Center to center spacing should not exceed 6 inches. In heavy load conditions, spacing should be as close as possible. Sprockets placed greater than 6 inches can lead to premature belt failure due to excessive strain on the connecting rods. All drive sprockets should be keyed in-line. Tail sprockets should have plain bores, except the middle sprocket which should be keyed to assure shaft rotation. Plain bore sprockets should be collared to prevent lateral movement.

Materials/Construction

• Cast Iron: Cast iron is the most common material for flat wire belt sprockets. All sprockets are accurately cast from high grade iron.
• Stainless Steel: Stainless steel is ideal for food and high temperature applications. Either investment cast or machined from T-304 stainless steel, stainless steel sprockets provide greater accuracy and a uniform tooth engagement for longer belt life. T-316L stainless steel sprockets are available on special order.
• Plastic: UHMW polyethylene sprockets feature fully machined teeth for precise meshing with the belt, and can withstand continuous temperatures up to 180 degrees. * USDA Approved for Food Use *
• High Temp UHMW Sprockets: LaX and Keystone offer high temperature UHMW sprockets as an special option. (please contact us) Standard UHMW can handle continuous temperatures up to 180 degrees Fahrenheit. High Temp UHMW sprockets are rated for a constant temperature of 225 degrees Fahrenheit and an incremental maximum temperature of 300 degrees Fahrenheit. Keystone stocks these sprockets in a few styles, and can provide others on a custom order basis. Expect a 4-5 week lead time. High Temp UHMW sprockets are designed by the addition of the word HOT after the standard part number.

Special Custom Features (contact us for pricing)

• Hardened Teeth: Hardened teeth may be supplied with cast iron sprockets and can increase sprocket life 2-3 times under severely abrasive and heavy load conditions.
• Bronze Bushings: These can be supplied for tail or idler sprockets to reduce shaft wear. Bushings are press fitted into sprocket bore.
• Cut Down Hubs: Cut down hubs are available for all sprockets enabling close sprocket spacing on heavy load applications.
• Special Coatings: Special coatings for corrosive resistance such as cadmium and nickel plating can be furnished for cast iron and steel sprockets.
• Machining of Teeth: Machining of teeth to provide clearance for use with 1/2" x 1" modified mesh belts is available.
• Square Bores: Keystone can add square bores into plastic sprockets only. Bore tolerance =+.020",-0". Set screws are not included but can be added for an additional price.
