Custom Adjustable Stainless Steel Leveling Castors for Machinery

The AstraRoll Technical Advantage

We engineer our leveling casters to safely lift multi-ton machinery while maintaining strict hygienic compliance:

2-in-1 Space-Saving Design: By integrating a high-capacity swivel caster and a leveling foot into one compact footprint, machine builders can simplify their chassis designs, reduce hardware costs, and eliminate the safety hazard of workers trying to manually lift equipment to install separate feet.

100% Stainless Steel Architecture: The top plate, swivel yoke, leveling stem, and internal bearings are manufactured entirely from high-grade stainless steel. They will survive daily chemical washdowns, high-pressure hoses, and sterile cleanroom protocols without ever oxidizing.

Anti-Vibration NBR Pad: The retractable leveling foot is fitted with an NBR (Nitrile Butadiene Rubber) pad. Once lowered, this pad grips the floor, preventing the machine from "walking" while actively dampening the harmonic vibrations generated by motors, pumps, or robotics.

Ergonomic Heavy-Lifting Gear: Lifting a 1,000 kg machine off its wheels is virtually impossible with a poorly designed dial. AstraRoll's precision-machined internal threads and optional ratcheting systems allow operators to smoothly raise or lower the leveling pad with minimal manual effort.

Why Choose AstraRoll?

1. True Stainless Steel Bearings

Many competitors sell "Stainless Steel" casters where the outer bracket is 304SS, but the hidden internal swivel ball bearings are cheap carbon steel. The moment water enters the swivel head, it rusts from the inside out and seizes. AstraRoll guarantees that every internal component—from the ball bearings to the raceway and the internal adjustment thread—is 100% stainless steel.

2. OEM Frame Integration

As a factory-direct manufacturer, we do not force your engineers to redesign their machinery to fit our casters. If your aluminum extrusion profile or steel chassis requires a non-standard bolt hole pattern or a specific metric thread pitch (e.g., M16 vs. M20), we will CNC-machine the top plates and stems to your exact specifications.

Frequently Asked Questions (FAQs)

Q: How do I calculate the load capacity needed for four leveling casters?
A: Factory floors are rarely perfectly flat. When moving a machine, the weight frequently shifts so that only three casters are bearing the entire load. Therefore, you must use the formula: (Total Weight of Machine + Max Payload) ÷ 3. For example, if your machine weighs 1,500 kg, each individual caster must have a load rating of at least 500 kg.

Q: How do I adjust the leveling pad when the machine is heavily loaded?
A: For light loads, you can rotate the adjustment thumbwheel by hand. However, for heavy machinery, it is impossible to turn it manually. You must use an open-ended wrench or a specialized ratcheting spanner on the integrated hex nut located on the adjustment stem to gain the mechanical leverage needed to lift the machine.

Q: Are these leveling casters ESD (Electro-Static Discharge) safe for electronics manufacturing?
A: Standard nylon or PU wheels act as insulators. If your machine is operating in an electronics cleanroom, you must request our Anti-Static (ESD) Option. We will equip the casters with specialized conductive wheels and grounding pads to ensure safe dissipation of static electricity.

Q1. Are you a trader or direct factory?

We are a direct manufacturing factory with over 20 years of expertise in high-end industrial rollers, casters and material handling solutions. Our facility operates with ISO-certified quality management systems, allowing us to maintain full control over production cycles and quality standards. Throughout two decades of growth, we have established deep, long-term strategic partnerships with several listed companies and global automation leaders, proving our reliability as a high-tier industrial supplier.

Q2. What are your main products?

AstraRoll specializes in the engineering and production of three core product lines: Industrial Rollers, Heavy-Duty Wheels, and Precision Casters. We do not just sell components; we provide integrated movement and transport solutions. Our products are widely utilized across high-demand sectors, including: New Energy, Lithium Battery, Mining, Heavy Industry, Medical Institutional, Agriculture and Logistics.

Q3. What about delivery time?

We deeply understand that project timelines are critical.
Standard Products: Usually dispatched within 7–15 working days if the components are in stock.
Customized/OEM Orders: Depending on the complexity and volume, the lead time typically ranges from 20–35 days. This includes time for technical drawing confirmation, specialized tooling, and rigorous pre-shipment testing.
Shipping Methods: We offer flexible global logistics solutions, including FOB and CIF terms. We ship via Sea Freight (for bulk industrial orders), Air Freight (for urgent project needs), and International Express (DHL/FedEx/TNT) for smaller components or samples.
