Yarssihha M8 30x20mm Anti-Vibration Isolators
Best for small diesel engines, air compressors, or vibration motors with limited mounting space. These 30x20mm mounts use a 60° Shore A rubber and a galvanized metal frame. They feature end screws die-cast onto washers to avoid rubber penetration, improving dynamic stability under lateral forces. Caution: the smaller footprint may limit load handling on heavier equipment.
- Rubber size: 30x20mm; Height: 60mm; Thread: M8 x 20mm
- Hardness: 60° Shore A (±5)
- Quiet operation and reduced wear from vibration
Yarssihha M8 40x40mm Anti-Vibration Isolators
Better for medium-duty applications where a larger mounting area is beneficial. With 40x40mm rubber, these mounts offer enhanced stability and higher dynamic performance for sideways forces. Best for diesel engines, air compressors, and vibration motors requiring stronger isolation. Limitation: larger footprint may require more clearance on compact assemblies.
- Rubber size: 40x40mm; Height: 80mm; Thread: M8 x 20mm
- Hardness: 60° Shore A (±5)
- Improved stability against lateral motion
YIEHRNS M12 40x30mm Rubber Stud Isolators
Designed for heavier loads and larger devices, these M12 mounts support robust equipment like split pumps, generators, and large air compressors. They feature a 40x30mm rubber body with M8 x 20mm threaded studs, combining strong rigidity with effective damping. Choose this if your setup requires higher load capacity and sturdy mounting. Caution: heavier mounts may require more mounting hardware and alignment precision.
- Rubber size: 40x30mm; Height: 70mm; Thread: M8 x 20mm
- Hardness: 60° Shore A (±5)
- Reduces wear and dampens noise effectively
DS. DISTINCTIVE STYLE Rubber Isolator Set (M8)
This 4-piece set is a versatile dampening option for cars, boats, or workshop gear. Made with a rubber surface and heat-resistant design, these mounts help protect machinery from operational vibration and noise. Best for general dampening tasks where a non-specific, universal fit is acceptable. Limitation: may lack the precise load ratings of purpose-built OEM mounts.
- Rubber isolation with heat and tension resistance
- Non-toxic and safe for general dampening use
- Suitable for air compressors, water pumps, and refrigerators
EASYEAH M10 Rubber Stud Isolators (4 Pack)
Best for mid-to-heavy industrial equipment like welders, garage motors, and diesel engines. The set includes four M10 isolators with nuts, providing a strong, corrosion-resistant mount and straightforward installation. They offer good deflection and noise reduction through vulcanized rubber and zinc-coated steel. Beware of using in extremely high-load contexts where dedicated heavy-duty mounts would be more appropriate.
- Thread: M10x28 mm; Stud size: 40×30 mm
- Load: 392 daN compressive; 60 daN shear (per 4 pcs)
- Includes M10 nuts for quick installation
Buying Guide: Key Purchase Considerations
How to choose the right anti-vibration engine mount depends on load, mounting space, and the type of equipment. Consider these factors:
- Load capacity: Match the mount’s compressive and shear ratings to your machine’s weight and operational forces.
- Footprint and height: Ensure the mount fits within the available clearance and aligns with bolt patterns.
- Material and hardness: Higher hardness offers better stability but may transmit more vibration; softer rubber provides more damping but lower load capacity.
- Stud size and threading: Confirm compatibility with your equipment’s mounting studs and nuts.
- Environment: For damp, humid, or corrosive environments, consider galvanized or coated hardware to resist rust.
- Installation complexity: Some sets include nuts or require additional washers; plan hardware accordingly.
Frequently Asked Questions
- What is an anti-vibration engine mount used for?
They reduce vibration and noise from engines and pumps, protecting equipment and improving operator comfort.
- How do I choose the right size?
Base size on the engine’s weight, vibration profile, and available mounting space; larger footprints often provide better stability.
- Are these mounts suitable for diesel engines only?
No, they work with various machines such as air compressors, generators, water pumps, and garage motors.
- Do mounts affect alignment?
Yes. Proper alignment ensures effective damping; misalignment can reduce performance and cause wear.
- Should I choose metal-on-rubber or fully rubber mounts?
Metal-on-rubber designs provide stronger support for higher loads; fully rubber mounts offer greater isolation for light to moderate equipment.
