Sanitary Levelling Feet

Usage of Sanitary Levelling Feet

Sanitary levelling feet are designed to provide a stable base for machinery while adhering to strict hygiene standards. Their primary functions include:

Ensuring Equipment Stability

Machinery stability is crucial for precision and efficiency in production lines. Unstable equipment can cause vibrations, leading to inaccuracies, downtime, and potential safety hazards.

Easy Cleaning and Drainage

Unlike traditional levelling feet, sanitary levelling feet feature self-draining surfaces, reducing water accumulation and bacterial growth. Their smooth, polished design prevents dirt and residue buildup.

Reducing Contamination Risks

These feet eliminate dirt traps, which are common in conventional adjustable feet, making them ideal for environments where hygiene is non-negotiable.

Improving Workplace Safety

By reducing slippage and machine movement, sanitary levelling feet contribute to a safer workplace, preventing accidents caused by machinery misalignment.

Sanitary Levelling Feet

The sanitary designed and protected levelling foot is the acceptable choice for machinery and equipment that has to comply with sanitary requirements.
The thread is covered with a sanitary sleeve, which also functions as counter nut. All the movable parts are sanitarily sealed.
Lowered cleaning effort is obtained by the design of the self draining surfaces.
Additionally, the foot is sanitarily sealed to the floor by vulcanized FDA-approved, anti-vibration, anti-slip rubber, which blocks out bacteria underneath the footplate.

Sanitary Levelling Feet

All process industries are subject to increasing regulatory requirements, which increases the focus on resource consumption, product safety and sanitary design.
The sanitary levelling feet reduce the water consumption and cleaning resources in addition to lowering the risk of contamination in the production.
Choosing NHK’s sanitary levelling feet will secure your machinery with an acceptable sanitary design and contribute to your customer’s Return-On-Investment.
