Our goal is to exceed our customers’ expectation in providing quality bearing products and continue to improve the services we provide on a timely manner.
We are pleased to announce the launch of our new 6703 ZZ series of deep groove ball bearings, which represent the pinnacle of bearing technology and performance. Engineered for a wide range of demanding applications, the 6703 ZZ sets a new benchmark for precision, quality, and reliability.
Featuring a double-shielded ZZ configuration, these high-speed bearings are optimized for use in harsh environments where contaminated conditions exist. The ZZ design utilizes metal shields on both sides of the bearing to maximize protection for the internal components.
The 6703 ZZ has inner and outer races precision machined from vacuum degassed 52100 steel, which offers optimal hardness, compressive strength, and dimensional stability. Inside, the full-complement silicon nitride hybrid cage retains the polished chrome steel balls in perfect geometrical positions for smooth, accurate rotation.
Silicon nitride demonstrates low thermal expansion and exceptional heat resistance compared to traditional bearing cage materials. This enables the 6703 ZZ to operate at higher speeds and temperatures with reduced lubricant oxidation. The properties of silicon nitride also dampen noise and vibration for exceptionally quiet running.
A specialized grease formulated for extreme pressures and temperatures is used to pre-lubricate the bearing. This provides exceptional protection against wear and corrosion while minimizing friction and operating temperatures. The lubricant maintains optimal viscosity even under heavy loads and in high heat environments.
Extensive quality control and testing ensures that every 6703 ZZ bearing meets the industry’s most stringent dimensional, noise, and vibration standards. Superior geometrical roundness and surface finish lead to balanced operation at super-high DN values over 2.3 million.
The 6703 ZZ is offered in a wide range of metric and inch sizes from 5 to 80mm bore diameters to suit most equipment needs. Custom designs are available, including specialized cage materials or hybrid ceramic/steel ball configurations for the most demanding applications.
