Overview
The Barry Controls LM1-B is a precision leveling foot mount engineered for vibration and shock protection in industrial equipment. This mid-capacity isolator provides a 100–300 lb load rating with full-inch neoprene elastomer construction and an adjustable leveling bolt that allows height adjustment up to one-half inch above the load. The LM1-B combines economical design with robust performance, making it an industry-standard component for machinery stabilization and alignment.
Key Features
- 100–300 lb load rating per mount
- Neoprene elastomer for shock and vibration isolation
- Adjustable leveling bolt for precision height control
- Full-inch elastomer for controlled deflection
- Natural frequency of 12–18 Hz with 8:1 transmissibility at resonance
- Durable, corrosion-resistant steel construction

Typical Applications
The LM1-B excels in protecting heavy industrial equipment from vibration and shock damage. Common installations include:
- CNC machines and machining centers
- Punch presses
- Milling and drilling machines
- Sanders and saws
- Injection molding equipment
- Boring and screw machines
- Lathes and grinders
Note: For punch press applications between 150–300 SPM, reduce the load rating of each mount by 50%. Contact Barry Controls at 1-800-BARRY-MA (1-800-227-7962) for applications exceeding 300 SPM.
Compatibility & Replacements
Compatible With
- Standard industrial machinery with center-bolt or bolt-down mounting
- Equipment requiring 0.375-24 UNC threaded connection
- Systems requiring neoprene elastomer isolation (standard machine tool environments)
- Equipment operating in temperature range -20°F to +180°F
Replaces / Drop-In Replacement For
The LM1-B has been discontinued by the manufacturer, but may be interchangeable with current-generation Barry Controls leveling mounts in equivalent load classes (e.g., LM0-B for lighter loads up to 100 lbs; LM3-B for heavier loads 300–1,000 lbs). Verify mounting hole pitch, bolt thread type, and elastomer material compatibility with your equipment specifications before substitution. Consult Barry Controls applications engineering at 1-800-BARRY-MA for direct replacement recommendations.
Works With
- Barry Controls metric and inch bolt & bushing kits for installation
- Standard adjustable leveling systems compatible with center-mounted machinery
- Precision alignment and vibration isolation workflows
- Equipment requiring elastomeric (non-pneumatic) isolation
