Corrosion resistance options for linear motion systems
There are many applications for linear motion guides that require protection against corrosion, including: industrial processes that require caustic washdown; machines operating in high-humidity or saltwater environments; medical equipment; chemical processes; semiconductor manufacturing; food and pharmaceutical packaging, amongst many others.
Given the requirement for corrosion resistance, many manufacturers and designers look to stainless steel products. But is that the optimum solution?
THK, the world's leading manufacturer of linear motion systems, offers a range of corrosion-resistant special surface treatments. THK's industrial black chrome plating AP-C treatment provides superior corrosion protection when compared to martensitic stainless steel.
THK rails and carriages with AP-C surface treatment are now held in stock at ACORN, a leading authorised THK Supply Partner. Rails are cut to suit customers' requirements and carriages fitted to create linear motion guide assemblies.
This means that THK AP-C surface-treated products are available for delivery in a few days, rather than weeks or months.
