Organ-type protective covers, also known as folded bellows covers, are essential components in CNC machine tools, milling machines, and industrial automation equipment. These covers are specifically designed to shield guideways, ball screws, and moving components from dust, metal chips, coolant, and other contaminants. Proper installation, usage, and maintenance of these protective covers ensure enhanced machine performance, longer service life, and reduced downtime.
At LIONSHELL, we manufacture high-precision organ-type protective covers tailored to your equipment needs. Below are detailed instructions and best practices to help you make the most of your bellows protection system.
Confirm Mounting Orientation: Ensure the organ cover is mounted in the correct direction: the folds must extend and retract naturally with the axis movement. Incorrect orientation can lead to jamming or premature wear.
Align with Machine Axis: The protective cover should be aligned perfectly parallel with the movement direction of the machine's slideways or screws. Misalignment causes uneven fold tension and possible tearing.
Use Proper Fasteners: Secure the ends of the bellows using recommended bolts, clips, or flanges provided by LIONSHELL. Avoid over-tightening, which may damage the frame or restrict natural movement.
Allow for Stroke and Compression: Confirm that the cover is capable of compressing and expanding fully along the machine’s stroke. Avoid forcing folds into a smaller space than designed.
Avoid Obstructions: Ensure the bellows have enough clearance to operate freely. Keep tools, cables, and other obstacles away from the folding area during machine operation.
Limit Overtravel: Never exceed the designed stroke or speed of movement. Overextension can tear the material or deform the support frames inside the bellows.
Protect from Heat and Sparks: In applications involving welding, plasma cutting, or high temperatures, use heat-resistant covers or add external shielding to prevent material degradation.
To ensure long-lasting protection, incorporate the following checks into your routine machine maintenance:
Check for tears, cracks, or pinholes on the bellows surface
Look for abnormal folding patterns or jamming during axis motion
Remove any metal shavings, oil, or debris collected on the surface
Verify that fasteners and mounts are still secure and vibration-free
Use compressed air or a soft brush to remove dust and particles from the folds
For oil or coolant splashes, wipe gently with a non-abrasive cloth and mild detergent
Never use sharp tools or harsh chemicals that may cut or degrade the surface material
If wear or damage is identified, contact LIONSHELL for replacement parts or customized repair solutions
If a bellows cover is to be stored before installation:
Keep it in a dry, shaded area free from direct sunlight or heat sources
Store in its original packaging to maintain the correct fold shape
Avoid placing heavy objects on top of the bellows to prevent deformation
Replace your organ-type protective cover if you notice:
Significant material fatigue or loss of flexibility
Continuous leaking of coolant or fine debris inside the machine
Repeated folding malfunctions that interfere with machine operation
Visible damage beyond patching or sealing
Organ-type machine tool protective covers are not just accessories—they are critical for maintaining machine accuracy and operational stability. By following proper installation, usage, and maintenance practices, you can maximize equipment protection and minimize costly downtime.
At LIONSHELL, we provide custom-designed bellows covers to fit your specific application needs. Whether you're upgrading an existing system or designing a new machine tool, our engineering team is ready to help.
