Wheels for the Food Industry

In the food industry, wheels are not chosen for their mechanical properties alone — they are chosen for their hygiene. Every component that comes into contact with or is located near food must meet strict requirements: it must not harbour bacteria, must withstand aggressive cleaning and must not introduce contamination.

Stainless food-grade wheels and their associated hardware represent a specialised segment of the wheel market, with demands found in no other industry. GM Rodes offers a complete range of solutions for food manufacturers, bakeries, dairies, meat processors and cold storage facilities.

HACCP Regulations and Hygiene Compliance

The HACCP (Hazard Analysis Critical Control Points) system is mandatory in the food industry throughout the EU. All equipment used in food production or storage — including trolleys and their wheels — must comply with HACCP principles.

What this means for wheels:

• No grooves or crevices in which food or bacteria can become trapped
• Smooth surfaces that allow effective cleaning
• Food-grade approved materials or at minimum materials suitable for use in food environments
• Resistance to chemical cleaning agents used in the food industry

Core principle: The easier the cleaning, the higher the hygiene level. Choose wheels with the fewest possible cavities and joints.

Stainless Steel: The Essential Choice

Stainless steel (inox) is the primary material for wheel swivel heads in the food industry, and for clear reasons:

• Corrosion resistance: Does not rust, even with continuous washing and wet environments
• Chemical inertness: Does not react with food, acids or alkalis
• Easy cleaning: Smooth surface does not retain dirt
• Withstands high-pressure washing: Stands up to hot water pressure cleaning

For wheel swivel heads in food environments, we recommend exclusively inox AISI 304 or AISI 316. AISI 316 is preferred in applications with high salt concentrations (seafood, dairies) due to its superior chloride resistance.

The wheel tread can also be made from inox — suitable for smooth floors and heavy loads. Alternatively, a food-grade polyurethane or white rubber tread is used for better rolling and non-marking performance.

Cold Storage Operation

Wheels for cold storage face an enemy that most people overlook: extreme cold. At temperatures of -20°C to -30°C, many materials harden, crack or lose their properties.

What to know about cold environments:

• Standard polyurethane: Hardens below 0°C and can become brittle. Avoid in cold storage.
• Low-temperature PU: Specially formulated for operation down to -30°C. Retains flexibility and load capacity at low temperatures.
• Rubber: Certain rubber compounds retain flexibility at low temperatures — select wheels that explicitly state suitability for sub-zero temperatures.
• Low-temperature bearing grease: The bearing lubricant must be rated for low temperatures, otherwise rolling becomes extremely difficult.

Important: When moving trolleys from cold storage to a warmer area, avoid abrupt temperature changes. Moisture condensation in cold environments also accelerates corrosion in unsuitable materials.

Resistance to Washdown and Chemical Cleaning Agents

In the food industry, equipment is cleaned daily — often multiple times per day. The cleaning agents used are often aggressive: alkaline detergents, chlorinated solutions, disinfectants based on quaternary ammonium compounds or hydrogen peroxide.

Durability requirements:

• Inox swivel head: Excellent resistance to all common food industry cleaning agents
• Food-grade PU tread: Withstands alkaline and neutral detergents. Check compatibility for chlorinated agents.
• White rubber tread: Good general resistance, easy visual hygiene inspection
• Avoid: Galvanised steel or painted swivel heads — chemicals strip the coating and create corrosion sites

Specific Applications: Bakeries, Dairies, Meat Processing

Each sector of the food industry has its own specific needs:

Bakeries:

• Flour and dough accumulate easily on wheels. Smooth, easily cleaned components are essential.
• Oven-loading trolleys require high-temperature wheels (up to 200°C).
• Recommended: inox swivel head + cast iron or heat-resistant PU tread for oven trolleys.

Dairies and Cheese Production:

• High humidity, salt, lactic acids. Corrosion is the primary enemy.
• Inox AISI 316 is essential for wheel swivel heads.
• Typical loads: 50–300 kg per wheel.

Meat Processing:

• Blood, fats, wash liquids — an extremely aggressive environment.
• Wheels resistant to fats and water with sealed bearings are required.
• Meat transport trolleys need wheels that operate in both freezer and room-temperature areas.

FDA-Compliant Materials

For export operations or businesses working to FDA (US Food and Drug Administration) standards, wheel materials must meet additional requirements:

• Treads from white or natural polyurethane of approved composition
• H1 grade bearing lubricant (suitable for incidental contact with food)
• Material documentation and compliance certificates from the manufacturer

Conclusion

Selecting wheels for the food industry is not just a technical matter — it is a question of hygiene, legal compliance and protecting your business reputation. The right inox food-industry wheels reduce contamination risk, simplify cleaning and meet HACCP and FDA requirements.
