STEEL TELESCOPIC COVER
High-strength steel telescopic covers protect machine guideways from impact, chips, dust and coolant while supporting stable reciprocating motion.
Machine Cover Selection and Custom Engineering
Configure a reliable cover around guideway size, travel, speed, mounting direction and operating environment.
NYLON BELLOWS COVER
Flexible PVC-fabric bellows combine compact compression with long travel to protect machine guideways from coolant, oil, chips and external impact.
ROUND BELLOWS COVER
Round flexible bellows protect leadscrews, cylinders, piston rods and shafts from dust, oil and coolant, with custom diameters and end connections.
ARMORED BELLOWS COVER
Armored bellows combine a flexible sealed body with metal lamellas for stable, low-noise guideway protection against chips, coolant and impact.
Four operating conditions to confirm before selecting a machine cover
A cover should not be ordered by appearance alone. Guideway dimensions, travel, actual speed and contaminants determine the structure, support and sealing method.
Dimensions and travel
Record guideway width and height, extended length, available compressed space and mounting interfaces before choosing the cover structure.
Speed and orientation
Horizontal, vertical and inclined installations carry different loads. High-speed travel also requires acceleration, synchronizing, guidance and buffering checks.
Chips and fluids
Identify metal chips, dust, coolant, oil and hot splash to choose between telescopic steel, bellows, armored or round covers.
Maintenance access
Confirm removal direction, cleaning frequency and nearby interference so seals, plates and mounting flanges remain serviceable.
Choosing the cover structure
| Structure | Suitable conditions | Confirm before ordering |
|---|---|---|
| Steel telescopic cover | Machine guideways exposed to metal chips, coolant and impact | Speed range, plate thickness, compression ratio and support |
| Nylon bellows cover | Compact equipment requiring long travel and flexible sealing | Fabric, compressed length, profile and mounting interface |
| Armored bellows cover | High-speed guideways needing flexible motion and chip impact resistance | Armor overlap, synchronized travel, noise and buffering |
| Round leadscrew cover | Leadscrews, cylinders, piston rods and other axial moving parts | Inside and outside diameters, travel, compression and end connections |
Information needed for selection
- Width, height or diameter of the protected component
- Maximum extended length and available compressed length
- Travel speed, acceleration and mounting orientation
- Chips, coolant, oil, dust and temperature conditions
- Interface dimensions, nearby interference and equipment photos
Machine cover selection questions
Is the extended length enough for a quotation?
Usually not. Compressed space, guideway dimensions, mounting interfaces, speed and contaminants are also needed to select the structure and material.
Can a standard steel cover run at high speed?
Speed must be classified. A high-speed cover needs matching synchronization, guidance and buffering; a standard pull-type cover should not use high-speed ratings.
Is vertical installation selected the same way as horizontal installation?
No. Gravity changes the load, so the speed range, support, stops and fixing method must be checked again.
Can you make covers for irregular guideways or retrofit projects?
Yes. Send a dimensional drawing, equipment photos and a motion video so the profile, travel, interface and interference points can be reviewed.
