The X5 option, available for the LEY series in sizes 25 and 32, is a dust and drip proof specification equivalent to IP65. For DC motor models, the spec is achieved by enclosing the motor in a sealed aluminum cover with a special cable connector, and pairing the rod with a scraper and lub-retainer. Additionally, the body extrusion includes a vent hole and fitting to balance internal pressure so that dust and water are not drawn in.
