Metal roll-up cover

verticalhorizontal

Product Overview
The Roll-up is a spring-rewind flexible protective cover where an internal spring automatically retracts the curtain. It uses a roll-up storage structure so the curtain occupies minimal axial space when retracted. Two main configurations are available: open roll-up and sealed housing. Fabric choices and housing materials are selected based on the working media and temperature.

Product Description
The Roll-up provides flexible protection for guideways, moving axes and other linear components where installation space is limited. High-quality springs prolong service life, while multiple fabric types and coatings allow selection per contamination, fluid exposure and temperature requirements. The design supports compact storage and straightforward integration into machine axes.

Working principle
The assembly consists of a roll housing, spiral spring mechanism, flexible curtain, guide strip and mounting flange. As the protected component moves outward, it pulls the curtain to cover the area. When the component retracts, spring pre-tension rolls the curtain back into the housing automatically. The unit supports horizontal, vertical and inclined mounting and requires no external drive power.

Core strengths

• Space-saving: curtain stored inside the roll housing, minimal compressed size compared with bellows
• Mechanical simplicity: spring-rewind mechanism, no motor required
• Fast response and suitable for medium-to-high-speed reciprocating motion
• Low added mass to moving parts

Protection capability
The Roll-up blocks dust, fine metal chips, cutting fluid and oil to protect guideways, ball screws and motion accuracy. Fabric options include wear-resistant coated cloth, oil-resistant rubber cloth, flame-retardant cloth and acid/alkali-resistant special cloth. Protection width, stroke and housing shape can be customized. Optional accessories include mounting flanges, guide groove assemblies, spring pre-tension adjusters and wear-resistant sealing strips.
