Key Advantages
Ultra‑slim, space-saving design (½″ wide) with consistent cross‑section as diameter increases – perfect for compact and lightweight designs.
Four‑point contact geometry supports radial, axial, and combined loads in both directions with high stiffness and minimal deflection.
High load capacity: Nearly 4,000 lbf radial and 6,570 lbf thrust dynamic loads ensure durability under stress.
Brass cage with chrome plating reduces friction, improves corrosion resistance, and ensures smooth ball motion.
Reliable under temperature variations: Operating range from –30 °C to 110 °C; suitable for most industrial environments.
Ideal Applications
Robotic joints & actuators
Medical imaging and positioning systems
Aerospace instrument mounts
CNC and precision automation tables
Telescopes, valves, and indexers
Why Choose ND110XPO?
