Wholesale Regular Duty Tennis Balls Supplier
Regular duty tennis balls are designed for consistent performance on hard and clay surfaces, with a felt covering that resists abrasion while maintaining playability over extended use. Their internal pressure and core construction are tuned to deliver a bounce height that meets ITF standards for recreational and training environments.
Technical Specifications
| Parameter | Typical Value |
|---|---|
| Diameter | 6.54 mm – 6.86 mm (ITF range) |
| Weight | 56.0 g – 59.4 g |
| Rebound Height (100 in drop) | 135 cm – 147 cm |
| Internal Pressure | 0.8 atm ± 0.05 atm |
| Felt Composition | 68 % wool, 32 % nylon (standard) |
| Core Material | Natural rubber compound |
| Durability (impact count before felt wear) | ≈ 2 500 impacts (standard play) |
Material Composition and Construction
The core is formulated from a high‑elasticity natural rubber blend that provides consistent pressure retention over thousands of impacts. A dual‑layer felt is applied via a steam‑press process, creating a uniform nap that enhances grip on racket strings while resisting fuzing. The wool‑nylon ratio is selected to balance softness for arm comfort with abrasion resistance for extended court life.
Performance Characteristics
Bounce consistency is verified by measuring rebound height after a standardized drop; variance within a batch typically stays below ±3 cm. Pressure loss over a 30‑day storage period at 20 °C remains under 0.02 atm, ensuring that balls supplied in bulk retain playability from first to last can. The felt’s tensile strength exceeds 15 N/mm, reducing the likelihood of premature shedding during intense rallies.
Applications
These balls are suited for high‑volume training programs where frequent replacement drives cost considerations, as well as for recreational facilities that require a reliable, ITF‑approved product. Their moderate felt durability makes them appropriate for clay courts, where excessive fuzz can affect ball speed, while still performing adequately on hard surfaces used in school and community programs.
Quality Control and Testing
Each production lot undergoes dimensional checks, pressure verification, and bounce testing according to ITF Appendix A. Visual inspection of felt uniformity and seam integrity is performed under standardized lighting. Statistical process control limits are set for weight (±0.3 g) and rebound height (±2 cm) to ensure batch‑to‑batch consistency.
| QC Item | Acceptance Criterion |
|---|---|
| Diameter | 6.54 mm – 6.86 mm |
| Weight | 56.0 g – 59.4 g |
| Rebound Height | 135 cm – 147 cm |
| Internal Pressure | 0.75 atm – 0.85 atm |
| Felt Visual Grade | No visible defects, uniform nap |
Packaging and Logistics
Balls are packed in pressure‑sealed cans of three, then stacked in corrugated cartons designed to withstand 15 kg stacking pressure. Each carton includes a desiccant packet to limit moisture ingress during transit. Palletization follows ISO 1444‑1 standards, facilitating efficient handling with forklifts and pallet jacks.
Ordering and Customization
Minimum order quantity starts at one pallet (approximately 4 800 cans). Customization options include alternative felt blends (e.g., 100 % wool for premium feel), private‑label printing on the can, and adjusted internal pressure for altitude‑specific performance. Lead time varies from two to four weeks depending on order size and destination.
Frequently Asked Questions
