MTB belt-driven linear actuators are discussed by PBC Linear application engineer Jeff Maina, highlighting the actuator's features that make it a robust platform, including a profile rail with runner blocks for low friction, noise, and vibration. The actuator body consists of an anodized aluminum housing with a stainless steel strip which seals along magnetic strips to shield out contamination from entering the linear actuator. Precision extrusions for each aluminum actuator body ensure for side and bottom surfaces that are flat and perpendicular giving accurate installations.
