WAD51 Heavy-Duty Leveling Foot with Thrust Bearing – M16/M12, 304SS, 1500kg Load Capacity

Factory direct | 304 stainless steel body & bearing | Thrust ball bearing for easy adjustment | 1500kg static load capacity | M16 / M20 / M24 thread options | Anti-slip | Shock-absorbing | Corrosion-resistant | OEM customizable

The Apexcoupling WAD51 series is a heavy-duty leveling foot (adjustable machine mount) engineered for precision leveling and vibration isolation in demanding industrial applications. Featuring a 304 stainless steel base and threaded stem with a thrust ball bearing at the bottom of the screw, this leveling foot allows for easy height adjustment even under full load. The bearing design prevents the screw from self-rotating under vibration when the lock nut is tightened, ensuring long-term stability. With a static load capacity of 1500kg, the WAD51 series is the ideal solution for medical equipment, semiconductor manufacturing, industrial machinery, CNC machine tools, automation equipment, and heavy furniture.

✅ Thrust ball bearing at screw base – easy adjustment under load. 304 stainless steel – corrosion-resistant, durable. 1500kg load capacity – supports heavy machinery. Anti-slip and shock-absorbing.

Product Structure

1. 304 Stainless Steel Base – Large-diameter circular base for stable support, electro-polished finish.

2. 304 Stainless Steel Threaded Stem – Precision-machined thread (M16/M20/M24) with uniform pitch for smooth adjustment.

3. Thrust Ball Bearing – Installed at the bottom of the screw – allows easy height adjustment even under full load.

4. Lock Nut – Prevents self-rotation under vibration – secures the set height.

💡 How it works: The WAD51 leveling foot is installed at the bottom of equipment or machinery. The threaded stem allows for precise height adjustment (typically ±3mm compensation). The thrust ball bearing at the screw base reduces friction, enabling smooth adjustment even when the equipment is fully loaded. Once the desired height is set, the lock nut is tightened to prevent the screw from self-rotating under vibration – ensuring long-term stability.

Thrust Bearing Design – Key Advantage

The WAD51 series features a thrust ball bearing at the bottom of the threaded stem:

✅ Recommended for: WAD51/52/53 series feature stainless steel bearings – ideal for high-humidity environments. For dry conditions, WAD54/55/56 with SUJ2 bearing steel are available.

WAD51 vs Other Leveling Feet – Which One Do You Need?

Recommendation:

• Choose WAD51 for high-humidity, washdown, food, or chemical environments where corrosion resistance is critical.

• Choose WAD54/55/56 for dry industrial environments where SUJ2 bearing steel is sufficient.

Why Choose Apex Coupling for WAD51 Leveling Feet?

FAQ

Q: What is a leveling foot?
A: A leveling foot (also called an adjustable machine mount or leveling mount) is an adjustable support installed at the bottom of equipment or furniture. It allows for precise height adjustment to ensure the structure stands level on uneven floors.

Q: What is the advantage of the thrust ball bearing?
A: The thrust ball bearing at the bottom of the screw allows for easy height adjustment even under full load. This significantly reduces installation time and effort compared to standard leveling feet without bearings.

Q: How do I prevent the foot from self-rotating?
A: After adjusting to the desired height, tighten the lock nut against the base. This prevents the screw from self-rotating under vibration, maintaining the set height.

Q: What is the maximum load capacity?
A: The WAD51 series supports a static load of up to 1500kg per foot. For higher load requirements, contact us for custom solutions.

Q: What materials are used?
A: The WAD51 series features 304 stainless steel for both the body and bearing – providing excellent corrosion resistance. The surface is electro-polished for a smooth, easy-to-clean finish.

Q: What thread sizes are available?
A: Standard thread sizes are M16, M20, and M24. Custom thread sizes available on request.

Q: What base diameters are available?
A: Standard base diameters are 60mm, 80mm, 100mm, and 120mm.

Q: What length options are available?
A: Standard lengths are 100mm, 125mm, and 150mm. Custom lengths are available in 25mm increments.

Q: What industries is this suitable for?
A: Medical equipment, semiconductor manufacturing, CNC machine tools, industrial machinery, food processing, pharmaceutical equipment, and automation.

Q: Can I get a custom leveling foot?
A: Yes. We offer OEM customization – custom lengths, thread sizes, base diameters, and materials available.
