The green heavy duty tennis ball is engineered for prolonged use on hard courts and intensive training environments where standard balls lose pressure and felt integrity quickly. Its construction combines a high-density rubber core with a thicker, wear-resistant felt covering to maintain consistent bounce and visibility over extended play cycles. This design reduces the frequency of ball replacement, lowering operational costs for facilities that require large volumes of balls daily.
Typical dimensions adhere to ITF standards with a diameter ranging from 6.54 mm to 6.86 mm and a weight between 56.0 g and 59.4 g. Internal pressure is set to approximately 0.80 bar to 0.85 bar, delivering a rebound height of 135 cm to 147 cm when dropped from 254 cm onto a concrete surface. The felt is a premium wool‑nylon blend, engineered for a minimum of 2,000 impact cycles before noticeable fraying.
| Parameter | Typical Value |
|---|---|
| Diameter | 6.54 mm – 6.86 mm |
| Weight | 56.0 g – 59.4 g |
| Internal Pressure | 0.80 bar – 0.85 bar |
| Rebound Height (254 cm drop) | 135 cm – 147 cm |
| Felt Composition | Wool‑nylon blend (≈80 % wool, 20 % nylon) |
| Impact Cycles Before Wear | ≥ 2,000 |

Facilities that schedule multiple coaching sessions per day benefit from balls that retain pressure and felt integrity over thousands of strikes, reducing the need for mid‑session ball changes. The vivid green color improves visibility against both green and clay backgrounds, assisting players in tracking spin and trajectory during fast‑paced drills. Schools and community courts that operate under tight budgets find the lower replacement frequency translates directly into reduced consumable expenses.
Each production lot undergoes dimensional verification using laser micrometers to ensure diameter stays within the 0.32 mm tolerance band. Pressure is checked with calibrated gauges, and bounce performance is validated on three replicate surfaces to confirm conformity to the rebound range. Felt abrasion resistance is assessed via a standardized Martindale tester, with acceptance criteria set at no more than 10 % weight loss after 2,000 cycles.
Clients may adjust the felt color to alternate high‑visibility shades such as optic yellow or orange while retaining the same heavy‑duty construction. Core hardness can be tuned within a 5 % range to match specific court speeds, and packaging can be configured for bulk cartons of 72 balls or smaller sleeve packs of three for pro‑shop resale. All modifications are subject to minimum order quantities that vary by specification.
Standard export packaging places balls in pressure‑maintaining, interleaved layers inside corrugated cartons rated for 20 kg gross weight, with each carton sealed with moisture‑resistant tape to prevent core degradation during transit. For domestic distribution, recyclable polyethylene bags holding three balls each are offered, labeled with batch codes for traceability. Lead time typically ranges from two to four weeks after receipt of a confirmed purchase order, depending on order volume and customization complexity.
Diameter and weight are held to ITF tolerances to ensure compatibility with official play; however, slight adjustments within the allowed range can be accommodated upon request.
Required details include desired quantity, any customization (felt color, core hardness, packaging), delivery destination, and required delivery date.
Standard offering is a wool‑nylon blend; alternative synthetics or higher wool content can be sourced depending on performance needs and order size.
Inspection includes dimensional checks, pressure verification, bounce testing, and felt abrasion evaluation as outlined in the quality control section.
Options range from bulk cartons of 72 balls to retail‑ready sleeves of three balls, with custom branding upon request.
