Bell-Everman (Goleta, CA) offers the SLS Light sealed linear stage that keeps contamination such as manufacturing debris, particulate, or liquid contaminants outside of the stage housing. The stage measures 80 × 120 mm, and has maximum dynamic payloads of 15 kg for the direct drive linear motor version, and 30 kg for the ball screw version. Both sizes deliver a proprietary linear lip seal design that integrates with the stage’s anodized aluminum housing. The seal is made from a ruggedized polyurethane elastomer and resists chemicals, temperature extremes, and mechanical wear. The seal can be quickly replaced without disassembling the stage or removing payload. Applications include anywhere that contaminants can threaten the operation of a linear actuator, including laser machining, welding, semiconductor, and machining.
