Swiss Jewel Introduces Sapphire Bearings—the Key to Long Wear Life and Mechanical Accuracy


When low friction, long life and dimensional accuracy are critical, Swiss Jewel Company of Philadelphia, PA, now offers a variety of highly-durable Sapphire Jewel Bearings engineered to withstand high rates of mechanical wear, without losing accuracy.

Swiss Jewel’s Sapphire Jewel Bearings are precision engineered of abrasion-resistant Sapphire, second only to diamond in terms of hardness (moh 9). Sapphire is also temperature stable and chemically inert, making it resistant to heat (up to 2,000°C), corrosion and distortion over sustained heavy use.

For reliability, Sapphire Jewel Bearings are machined and polished to the highest quality standards, ensuring smooth movement and dependable performance in critical mechanical operations, such as precision gauges, galvanometers, flow meters and aircraft instrumentation.

Plus, Sapphire Endstones can be used as Wear Seats to ensure points of contact remain true even after extreme repetition, ensuring ultra-precise positioning, which is key to highly-calibrated instruments.
