We are offering an excellent quality of Protective Bellows for all Type Guideways. This design covers three sides of the rail. They are great for blocking out dust, dirt, grit and other particles. They will also ward off some liquid spray, but since they don't totally encapsulate the rail, they're not recommended for water jet or other direct spray applications. While the materials of construction are quite durable and resistant to heat, very hot debris produced by welding or plasma torch can cause the bellows to fail prematurely. Alternate high-temperature construction is available. If you want to protect your linear bearings and rail from dust, dirt and other contaminants, we now have the perfect solution. Automation 4 Less offers 3-sided custom bellows produced in about two weeks for your EXACT application . Features: Abrasion and temperature resistance High efficiency Low maintenance
