Allen-Bradley 6156 ACF-25 Lead Screw Boot Cover

Allen-Bradley 6156 ACF-25 Lead Screw Boot Cover is a protective bellows that shields exposed lead screws from dust, debris, coolant, and other contaminants while helping retain lubrication in linear motion systems. With an inside diameter of 1-1/8 in and an extended length of 18 in, this flexible industrial bellows cover installs slip-on or is mounted on equipment to protect lead screws in CNC machines, machine tools, linear actuators, and other industrial automation equipment. It is designed to keep contaminants out of the screw drive while preserving lubrication, extending the service life of drive components in harsh industrial manufacturing facilities. Typical applications include CNC machining centers, milling machines, packaging equipment, automated production systems, screw jack assemblies, and material handling equipment where exposed lead screws require protection. The part is intended for use in linear motion and lead screw systems and is compatible with CNC machines, linear actuators, and screw jacks. Maintenance teams, OEMs, and system integrators use the 6156 ACF-25 for preventive maintenance, equipment repairs, retrofit projects, and replacement of worn protective bellows. Common replacements cited alongside this part include Joyce Dayton Protective Boot, Nook Industries Bellows Boot, and McMaster-Carr Lead Screw Bellows.
