Products Description
Rubber Balls with a Hole (also known as drilled or bored rubber spheres) are specialized elastomeric components designed for easy mounting, threading, or sliding along a shaft. By incorporating a precision through-hole or blind hole, these versatile balls are widely used as ergonomic shifter knobs, sliding track dampeners, valve floats, and anti-vibration mounts on threaded rods. We manufacture high-quality custom rubber balls with holes using advanced molding techniques, eliminating the need for secondary drilling and ensuring a perfectly concentric, tear-resistant bore. Available in EPDM, Silicone, NBR, and Polyurethane to meet your specific wear, chemical, and environmental requirements.
Product Features
Precision concentric molding
Our advanced molding process creates a seamless, perfectly centered through-hole or blind hole without secondary drilling, ensuring structural integrity and preventing tear propagation.
Versatile mounting & threading
Designed to slide smoothly over metal shafts for vibration damping, or can be custom-threaded internally for secure, permanent attachment as ergonomic control knobs and handles.
Exceptional shock & vibration damping
Acts as a resilient, omnidirectional bumper when mounted on rods or tracks, effectively absorbing mechanical impacts and isolating high-frequency vibrations in heavy machinery.
Custom bore sizes & materials
Fully customizable with exact bore diameters to match your mating hardware, and available in premium elastomers like high-abrasion Polyurethane, oil-resistant NBR, or food-grade Silicone.
