AutomationDirect has added three styles of polymer (plastic) bearings and compatible hard anodized aluminum linear shafts to its mechanical power transmission line.
igus DryLin R series linear plain bearings (from $6.00) are dimensionally interchangeable with other popular brands, and offer a low-cost alternative to recirculating ball bearings. The low-friction polymer material is suitable for wet or dirty environments. Available in four shaft diameters in fixed and self-aligning housings, they are ideal for use with DryLin R aluminum shafts.
igus igubal series mounted spherical bearings are engineered from L280 polymer to be lubrication-free and maintenance-free. They are lighter and more economical than traditional mounted spherical bearings. Starting at $10.25, these bearings offer excellent wear resistance in five popular mounting configurations to fit four common shaft sizes.
igus iglide series plain bearings (from $6.75) are economical, dry-running and maintenance free. Offered in three popular materials, J (low friction), G300 (general purpose), and T500 (high temp), these sleeve and flange bearings are an excellent choice for a wide range of motion applications. They offer good chemical resistance and fit shafts from 1/4 to 1 inch.
Starting at $9.25, igus DryLin R series hard-anodized shafts were specifically developed as the optimal sliding surface for DryLin R linear bearings. These hard-anodized aluminum shafts are available in four diameters and three lengths (up to 1m) in both round and fully-supported shafting.
