Description
Custom Vibration Dampening PU Rollers For Precision Weighing
Why Choose This Product
These rollers are engineered for weighing platforms, checkweighers, and dynamic conveyor scales, where even small oscillations can directly affect measurement accuracy.
Specially formulated polyurethane layer: Our PU compound reaches a tan delta up to 0.35, which absorbs vibration and prevents resonance transfer from nearby machinery. This reduces reading fluctuations and improves measurement repeatability in continuous weighing operations.
Low compression set below 2 percent: The roller keeps its original shape and contact consistency through thousands of cycles, extending calibration intervals and reducing maintenance downtime for your equipment.
Full customization for OEM and ODM projects: We adjust Shore hardness from A55 to A95, tune the damping ratio, add conductive or anti-static properties, and machine the core to your exact shaft and mounting specifications. This makes our rollers a flexible custom solution for weighing equipment builders, automation integrators, and industrial end users.
Certified quality with direct factory pricing: Every batch is produced under ISO9001 procedures and inspected for dimensional accuracy and hardness before shipment. You get stable quality, expert advice, and a cost-effective price for your market.

Production and Inventory Policy
Lead time: Actual delivery time depends on raw material supply, processing equipment, and peak season workload, so reasonable fluctuations may occur. We provide an accurate delivery estimate after order confirmation and keep you informed throughout production.
Stock status: In principle, we do not keep large stock, although some popular standard sizes may be available. Stock levels change dynamically with sales and production, so we recommend confirming real-time availability before placing an order.
Bulk and urgent orders: For high-volume orders or urgent requirements, please contact us in advance so we can coordinate our capacity and schedule. We will do our best to fit your timeline.
Frequently Asked Questions
1. Can you provide custom vibration dampening PU rollers for precision weighing equipment?
Yes. Our production line is built around custom solutions. We adjust the PU formulation, hardness, core size, shaft type, and surface finish to match your weighing equipment and accuracy requirements. OEM and ODM projects are welcome, and our engineering team provides expert advice during the design phase.
2. What hardness is recommended for precision weighing applications?
For most precision weighing systems, Shore A 65 to 85 is a practical starting range. A softer roller absorbs more vibration but supports lower loads, while a harder roller gives better load stability. We can test your actual sample and recommend the optimal hardness based on load, speed, and accuracy targets.
3. What is the minimum order quantity for custom PU rollers?
For custom sizes with a standard formulation, the MOQ is 10 pieces. For fully customized formulations, such as a modified damping ratio or a special color, the MOQ is 50 pieces. Prototype samples can be produced within 7 to 12 days for your evaluation before mass production.
4. How do your rollers improve weighing accuracy?
Our PU formulation absorbs micro-oscillations in the 20 to 200 Hz range and minimizes resonance transfer from conveyors and nearby equipment. This reduces reading variability, improves repeatability, and helps your weighing platform maintain accurate measurement for longer periods between calibrations.
5. Can you supply conductive or anti-static rollers?
Yes. We offer custom conductive formulations with surface resistance from 103 to 106 ohms, which suits powder handling lines and potentially explosive weighing areas. Please specify the required resistance range so our team can adjust the material formula.
6. What is the typical delivery time for bulk orders?
For confirmed bulk orders, the typical lead time is 15 to 25 working days, depending on the formulation, quantity, and current production load. We provide a realistic schedule at order confirmation and send regular production updates.
7. Can you work from our drawing or an existing sample?
Of course. Send us a 2D or 3D drawing, or a physical sample. Our team reviews the dimensions, tolerances, and material requirements, then returns a competitive quotation with technical recommendations. We often suggest improvements such as a higher damping formulation or better abrasion resistance for your specific market.
8. What payment methods do you accept?
We accept T/T, L/C, Western Union, and PayPal for prototype samples. For regular mass production, T/T with a 30 percent deposit and 70 percent before shipment is our standard term. Flexible terms can be discussed for long-term cooperation programs.
