Linear guides for food processing machines: corrosion- and chemical-resistance at its core
Original by Jan Michels (rewritten by Shizu Yamaguchi)
In meat and fish processing equipment, as well as in fruit and vegetable processing and filling operations, frequent and thorough cleaning is a daily requirement. The use of aggressive cleaning agents can place sustained stress on machine components, including frames, housings, fasteners, and linear motion systems. Without adequate corrosion resistance, even well-engineered systems can fail sooner than expected.
Material Selection for Corrosion Resistance
drylin W linear guides are intended for these environments, providing strong resistance to corrosion and chemicals. The secret sauce is in its components. Paired with polymer plain bearings, they are available in 316 stainless steel, which is commonly known to resist corrosion from liquids, including salt water. The guides are dry-running, meaning they operate without the need for external grease or oil. This removes a common source of contamination in food processing equipment. For applications with additional regulatory or operational requirements, our linear guides can be supplied with food-grade plastic bearing liners.
Designed for Easier Cleanup
The choice of materials simplifies cleaning procedures. Smooth surfaces, corrosion-resistant alloys, and dry-running bearings allow intensive washdowns without special safeguards or disassembly. This enables equipment designers to meet hygiene requirements while keeping maintenance demands low.
Benefits That Stay Off the Plate
The system allows unrestricted cleaning and disinfection paired with high resistance to corrosion and aggressive cleaning chemicals. Its grease-free operation also eliminates the risk of product contamination from external lubricants.
