Guarded Linear Axes Emerge as Dual-Purpose Solution for Factory Floor Hazards

The push for safer industrial equipment has moved beyond simple machine guarding to smarter, integrated design. Engineers and plant operators are increasingly weighing how to protect both personnel and precision machinery in environments where downtime carries a heavy cost. Recent technical assessments from mid-2026 highlight a growing trend: combining mechanical barriers with maintenance-free operation in a single component package.
Open linear axes have long been a quiet liability on automated production lines. Small workpieces, metal shavings, or airborne dust can work their way into exposed mechanics, leading to seized motion or accelerated wear. Just as problematic is the human factor — a worker reaching into a moving assembly risks serious injury. Addressing both concerns at once has become a priority for design teams.
Cologne-based motion plastics specialist igus has positioned its drylin ZLX and SLX axis systems to meet this challenge. Both product lines can now be specified with a metal cover that serves a twin function. On one side, it forms a physical seal against foreign objects entering the drive mechanism. On the other, it acts as a protective barrier that keeps hands and fingers away from moving parts during operation. The result is a reduction in both accident exposure and unplanned stoppages caused by external interference.
Protecting workers from moving machinery is a core duty under UK health and safety law — and documenting those safeguards properly is just as important as installing them.

The technical specifications differ markedly between the two drive concepts, yet the protective covering fits both without compromising core performance. The ZLX, a belt-driven axis, targets high-speed applications and reaches velocities up to 3 m/s with a maximum load rating of 150N. The SLX, by contrast, relies on a spindle drive and is engineered for far heavier duty. It handles radial loads up to 500kg and supports a lifting load of 100kg. Offering the same guarding option across both platforms lets engineers standardise safety protocols regardless of which drive technology an application requires.
One of the more compelling arguments for these enclosed systems is their lubrication-free operation. Because the axes run without grease or oil, they suit sectors where contamination is unacceptable or where routine maintenance is logistically difficult. That characteristic, paired with the protective metal shroud, broadens the range of viable deployment scenarios considerably.
When equipment operates in public-facing or high-dust environments, the safety case extends beyond the factory floor — and so does your compliance paperwork. A free Health & Safety Toolkit provides risk assessments, checklists and toolbox talks covering COSHH, PUWER and the Health & Safety at Work Act 1974, helping you protect employees, visitors and the public alike.

Beyond conventional factory automation and warehouse logistics, guarded linear axes are finding their way into publicly accessible spaces. In such settings, preventing tampering or accidental contact becomes especially critical. The absence of lubrication points cuts lifecycle costs, while the robust cover keeps the mechanism functioning reliably even under heavy dust loads or in environments with abrasive particles. For safety-conscious manufacturers, this combination of passive protection and reduced upkeep is shifting the baseline for what counts as responsible machine design.
