Wholesale Precut Tennis Balls for Walkers
Precut tennis balls serve as low‑friction glides on the legs of walkers, reducing wear on flooring and providing smooth mobility for users. The precut feature typically consists of a longitudinal slit that allows the ball to be snapped onto a walker tube without adhesives or fasteners.
Technical Specifications
Standard balls are manufactured from a natural rubber core wrapped in a woven nylon‑felt cover. The core provides rebound resilience while the felt contributes to abrasion resistance and consistent surface texture.
Nominal diameter measures 67 mm with a tolerance of ±0.5 mm. Weight averages 58 g per ball, influenced by felt density and rubber formulation. Hardness, measured by Shore A, falls in the 45‑55 range, offering a balance between softness for floor protection and firmness for durability.
| Parameter | Typical Value | Tolerance |
|---|---|---|
| Diameter | 67 mm | ±0.5 mm |
| Weight | 58 g | ±2 g |
| Shore A Hardness | 48 | ±3 |
| Slit Width | 6 mm | ±0.5 mm |
| Slit Length | 30 mm | ±1 mm |
Applications
Walker manufacturers integrate these precut balls into the design of front and rear legs to eliminate metal‑on‑floor contact, which reduces noise and prevents scratching on hardwood, tile, or laminate surfaces.
Rehabilitation centers and long‑term care facilities specify the balls as a replaceable wear component, allowing maintenance staff to swap worn units quickly without tools, thereby minimizing equipment downtime.
Customization Options
Slit geometry can be adjusted to match specific tube outer diameters, ensuring a secure snap‑fit. Common tube sizes range from 19 mm to 25 mm OD, with corresponding slit widths from 5 mm to 8 mm.
Felt color is available in standard white, high‑visibility yellow, or custom pantone matches upon request. Core rubber formulations can be tuned for increased rebound or lower compression set depending on expected load cycles.
- Tube OD 19 mm → slit width 5 mm
- Tube OD 22 mm → slit width 6 mm
- Tube OD 25 mm → slit width 7 mm
- Optional anti‑microbial felt treatment
- Custom logo embossing on felt surface
Quality Control
Each batch undergoes dimensional verification using calibrated calipers and a statistical process control plan targeting a Cpk of ≥1.33 for diameter and weight.
Compression testing is performed on a universal test machine at a strain rate of 100 mm/min, recording force‑deflection curves to ensure energy return stays within 40‑55 % of input.
Abrasion resistance is evaluated with a Martindale tester; a minimum of 20 000 cycles without visible felt degradation is required for release.
Packaging & Logistics
Standard packaging consists of 500‑piece corrugated cartons with internal polyethylene liners to protect against moisture and deformation during transit.
Cartons are palletized at 1 200 mm × 1 000 mm footprint, stacked two high, and secured with stretch film. Export shipments comply with ISPM‑15 standards for wood packaging when applicable.
Frequently Asked Questions
- Can the slit dimensions be customized? Yes, slit width and length are adjusted to match the walker tube OD and wall thickness provided by the customer.
- What information is required for a quotation? Required details include target tube OD, desired felt color, any special additives (e.g., anti‑microbial), order quantity, and preferred delivery schedule.
- What materials are available for the core? Standard natural rubber is offered; alternative synthetic rubbers (e.g., SBR, EPDM) can be supplied upon request for specific temperature or ozone resistance needs.
- How is quality inspected? Incoming raw material is tested for specific gravity and tensile strength; finished goods are checked for diameter, weight, hardness, and slit integrity using automated gauges and manual visual inspection.
- What packaging options exist? Besides the standard 500‑piece carton, we offer 250‑piece inner boxes, bulk bags of 2 000 pieces, and custom‑printed cartons for branding.
- How are export shipments protected? Cartons are lined with moisture‑barrier film, pallets are wrapped with UV‑stable stretch film, and corner boards are added to prevent edge damage.
- What is the typical production lead time? Lead time ranges from 15 to 25 working days after receipt of approved artwork and material confirmation, depending on order size and current plant load.
- How are samples arranged? Free sample packs of up to 20 pieces can be shipped via express courier; the customer covers freight charges or arranges their own carrier.
