Bellows

Protective Bellows

Protective Fabric Bellows are the economical solution for the protection of machinery and machine tooling where space constraints prevent the installation of more comprehensive protective equipment. Protective Bellows are an essential part of many different industrial systems. They are flexible seals used as protective covers for rod-ends, ball joints and numerous situations requiring the maximum possible protection from dirt, oils and swarf.

Our Protective Bellows can be manufactured in various fabrics and rubber compounds in shapes and sizes to suit any application. Guard-Tech’s designers select the correct materials, design and construction to solve your protection needs.

Our Protective Bellows can come with threaded inserts, holes in specified places and strong-hold Velcro strips for ease of removal and inspection. We can manufacture Protective Bellows with steel flanges for extra protection in harsh environments or for when the swarf is particularly sharp or hot. The steel flanges not only add extra protection to the Bellows but also enhance the appearance of the machine in question.

Large or small, all our Protective Bellows are designed and manufactured to suit customer’s requirements and are Quality Assured to ISO 9001:2015 Certification.

Why Protective Bellows Are a Smart Investment

Super cheap way to keep dirt out Often the lowest-cost option to protect ball screws, linear rails, cylinders, and spindles from chips, dust, and coolant.

Seal tight where nothing else fits Perfect for odd shapes, round columns, vertical lifts, or tight spaces where telescopic covers or aprons won’t go.
Zero extra weight or inertia Fabric or moulded bellows add almost no mass, so they don’t slow down high-speed axes or use extra motor power.
Flex in every direction They stretch, bend, and twist – great for robot arms, Z-axes on gantry machines, or anywhere the motion isn’t just straight.
Quick and easy to replace Most are held with Velcro, clamps, or simple flanges. Swap one out in 10–20 minutes instead of hours for steel covers.
Available for extreme conditions
- Heat-resistant to 300–500 °C (Kevlar or coated versions)
- Fully coolant-proof (PVC or polyurethane)
- Cleanroom-certified (no particle shedding)
Save expensive repairs One ball screw or linear rail ruined by chips can cost £5k–£25k to replace. A £200–£1,500 bellows stops that happening.
Make old machines last longer Put new bellows on a 15-year-old CNC and it suddenly stops eating guides and screws – instant life extension.
Look tidy and professional Clean black or coloured bellows make any machine look well-maintained and cared for.
Super-fast payback Typical cost £150–£2,500 per axis, and they usually pay for themselves the first time they stop and prevent a £10k+ repair to the vital parts of your Machine.

Protective bellows are the cheapest, lightest, most flexible way to stop swarf and coolant killing your expensive precision parts. Most shops keep a spare set in stores because they know one torn bellows left unreplaced can cost them a fortune.
