1PCS Spiral Steel Tape Protection Bellows for Ball Screw, Multi-Size Dust & Oil Proof Cover (20-250-40-38 to 50-900-75-70)(20-1000-50-38)

1PCS Spiral Steel Tape Protection Bellows for Ball Screw, Multi-Size Dust & Oil Proof Cover (20-250-40-38 to 50-900-75-70)(20-1000-50-38)

• Full-specification precision adaptation: Provides over 20 size combinations (such as 20-250-40-38, 25-1000-50-45, etc.), precisely matching the diameter, stroke, and compression requirements of different ball screws. The range covers small ends from 20-50mm, large ends from 28-70mm, and lengths from 250-1500mm.
• Tough and resilient protection with spiral steel strip: Equipped with high-strength galvanized steel strip support, it is resistant to pressure and impact, effectively blocking metal debris, oil stains, and dust, thereby extending the service life of the ball screw.
• Dynamic telescoping without resistance: The spiral structure can expand and contract freely, with optimized compression ratio (e.g., 40mm→250mm), supporting high-speed reciprocating motion without affecting the operational accuracy of the equipment.
• Industrial-grade oil-resistant material: outer layer of oil-resistant rubber or PVC coating, embedded steel strip for rust prevention, suitable for harsh environments such as CNC machines and injection molding machines.
• Ready-to-use design: Equipped with metal clamps or threaded connectors on both ends, it can be directly fixed to the ends of the screw without the need for tools, and requires no maintenance after installation.
