W’ve seen too many precision CNC machines "walk" across factory floors because of cheap, injection-molded leveling feet that fail under lateral stress. When a coating peels or the Shore hardness is off by even 0.2%, you aren't just losing a bolt; you’re risking expensive equipment misalignment and constant, costly recalibration downtime.
At our China factory, we’ve spent 10 years perfecting the Cast Polyurethane process, which we’ve found offers 3x the shear strength of standard options. Our custom-engineered PU coated bolts, manufactured to ISO & PEPSEN enterprise standards(Q/SHBS 001-2023), are tested to last 12+ months in high-vibration environments like automotive lines and mining. We don't compete on the lowest price; we compete on the lowest "total cost of ownership" by ensuring your machines stay level and your floors stay protected.
Customization Options:
We design polyurethane coated leveling bolts around real equipment loads, floor conditions, and installation limits, not catalog fantasy. In our OEM work, the right mix of thread, hardness, coating thickness, and base geometry usually decides whether a machine stays level for months or needs readjustment after a few weeks.
These bolts are used where steel-on-floor contact creates vibration, slipping, or floor damage. We supply them for equipment that must stay level under load, especially in factory lines where downtime is expensive and maintenance teams want a part that installs fast and works without drama.
- Packaging machines need stable machine leveling bolts to reduce shake during fast indexing and sealing.
- Conveyor support frames use polyurethane coated bolts to cut noise and stop sliding on smooth concrete floors.
- Warehouse sorting systems use heavy duty leveling bolts where floor flatness is poor and rolling impact is frequent.
- Textile and printing machines need non-marking leveling bolts to avoid floor damage and reduce resonance.
- Automotive subassembly stations use adjustable leveling bolts for steel frames, jigs, and operator platforms.
- Mining support equipment uses wear-resistant leveling bolts in dusty areas with high static load.
Advantages of Polyurethane Coated Leveling Bolts
We’ve tested every competitor’s injection-molded version and watched them fail at the seams. Our cast process creates a single-piece bond that simply doesn’t break, and the data backs it up every single time.
- Resists oil, grease, and chemicals that destroy standard coatings in weeks.operations
- Withstands 15,000 compression cycles with zero cracking.
- Cuts vibration transmission by 30 dB, quieter than rubber or plastic pads.
- Maintains level within 0.5 mm after 8 months of 24/7 mining use.
We are not trying to win with pretty words. We win when the bolt stays level, the coating does not peel early, and your maintenance team stops complaining. We support practical pricing, clear parameters, sample supply, low MOQ, and after-sales service that answers real problems instead of hiding behind sales language.
- We quote by drawing, load, and quantity, so price stays tied to real parameters.
- In many OEM orders, cast PU lasts longer than glued pad solutions under repeated adjustment.
- We support sample orders for fit check, hardness review, and floor-contact validation.
- Low MOQ helps clients test new equipment models without overstock pressure.
- We provide parameter sheets for hardness, dimensions, thread, and estimated load range.
- Our factory team can suggest design changes before mass production.
- We support China export packing for distributor and OEM supply programs.
- After-sales service covers installation feedback, failure review, and replacement advice.
- We do not push injection molding for this part when thick PU performance matters.

Selection Guide of Polyurethane Coated Leveling Bolts
This guide helps you choose the right PU coated leveling bolts by load, environment, thread and size to avoid wrong purchases.
- Confirm Load & Working Environment
Check total machine load and daily working hours.
Confirm if used in oily, wet or high‑vibration areas.
- Choose Correct Thread Size
Select from M8 to M24 based on your equipment design.
We can customize non‑standard threads for OEM projects.
- Select PU Hardness
Use 60–70A for general cushion and vibration control.
Use 80–90A for heavy‑load and high‑pressure machines.
- Confirm Length & Installation Space
Provide total height and installation space for accurate sizing.
Custom length avoids modification and installation trouble.
- Test with Samples
Confirm performance before placing bulk orders.
Request samples to test in your real working conditions.
Why do you insist on Cast PU over Injection Molding?
In our 20 years as a manufacturer, we’ve seen injection-molded bolts fail under shear stress. Casting creates a chemical bond that is 3x stronger, preventing the PU from slipping off the metal base.
What is the MOQ for OEM polyurethane coated leveling bolts?
Only 200 pieces minimum, even for full custom cast designs and special hardness. Perfect for pilot runs or small factories.
What parameters should I send for quotation
Send thread size, total length, base diameter, load per point, polyurethane hardness if known, usage environment, and quantity. A drawing or site photo helps a lot.
Are you a manufacturer?
Yes. We are manufacturer. Welcome to visit our factory.
Can you introduce your customized process ?
Yes. The process includes Share needs → design & quote → prototype (opt) → production → delivery.
How do you control your product quality?
We have 10 inspectors to carry out raw material inspection, process control ,first article inspection and final inspection.
How do you monitor the production process to avoid delayed delivery?
We use the ERP system to execute orders, and can check the order status and expected delivery time at any time.
What is warranty of products?
All of products with 3-6 months guarantee (except very frequently wearing parts).
How do you deal with after sales service?
We will response in 24 hours with solutions such as replacement or reworking.
How do you deal wtih customers' molds?
We have dedicated personnel to sort out and maintain molds regularly.
What about the lifespan of molds?
20,000 times for compressions molds and 30,000 time for casting molds
How long can you keep customers' molds for free?
Due to the large quantity of molds, we can keep the molds for free for 2 to 3 years even if no order.
If the molds are damaged or reach the lifespan , who will be responsible for it ?
Customers only need to pay mold cost once. We will cover the cost if molds are damaged or reach the lifespan.
