High-grade nylon sheaves are reinforced with fiberglass. Standard bearings are imported # 6203-2RS that are rated A.B.E.C.-1 precision and have radial seals. U.S. made bearings are also available. Bore adapters are sintered powdered metal. Bearing grease is Chevron SRI-2 or the equivalent, which has an operating temperature range of -20° to 350° F, complies with Mil-Spec MILG3545G, and passes ASTM D 1743-73 rust test with 5% synthetic sea water.
- Molded-in bearings extend belt life. Our molded-in bearings are more precise than pressed-in bearings. Pressed-in bearings may slip from side to side by as much as 1/16", meaning adjacent idlers can be out of line by 1/8". The resulting misalignment can cause premature belt wear. Our bearings do not slip and are designed to have superior T.I.R. (+/- .010" max.). True-running idlers extend belt life.
- Rugged. Our idlers are used in the hostile environment experienced by commercial lawn mowers where high speeds (3600 rpm) and high temperatures (170°F) far exceed stresses encountered in most conveyors. Even under such severe conditions, our molded-in bearings will not separate from the fiberglass-reinforced nylon rim.
- Higher Quality and Lower Prices. The production of molded-in bearings requires fewer steps. This facilitates automation, improves quality, and reduces costs. Consequently, our prices are very competitive.
- Stack and link our standard idlers. No need to buy expensive customized twin idlers. No tooling charges. You can even stack different diameters and different types. Fast delivery. Made from high-grade nylon reinforced with fiberglass. A.B.E.C.-1 bearings.
