Radial Super Precision Bearings

‌FAG’s Radial Super Precision Bearing has the following features and advantages:

‌High Precision ‌: FAG’s Radial Super Precision Bearing has a precision of up to P4S level, far exceeding the general bearing precision standards such as DIN/ISO or ABEC. This high precision enables the bearings to meet the most stringent requirements and show excellent performance in many industries ‌ ‌ High-quality materials ‌: FAG bearings are made of high-quality materials, such as Cronidur 30 steel. This high-nitrogen stainless steel is significantly superior to standard bearing steel in terms of metallographic structure, impact toughness, dimensional stability and hardness, thereby improving the life and performance of the bearing ‌ ‌ Excellent manufacturing process and quality control ‌: FAG pursues the best grease lubrication at the highest speed, and the realization of this goal requires strict and precise inspection and testing. This pursuit of perfection and precision has created the excellent quality of FAG bearings. ‌ Widely used: FAG high-precision bearings are widely used in many industries, can meet various stringent application requirements, and show excellent performance and reliability. ‌ Long life: Through high-quality raw materials and exquisite manufacturing technology, FAG bearings have an extremely long service life. As long as they are operated according to specifications, maintained and refueled regularly, the inconvenience and loss caused by disassembly and replacement of parts can be effectively reduced.

As the apex of Schaeffler Group’s bearing technology, FAG Radial Super Precision Bearings redefine performance boundaries in applications demanding near-zero vibration, extreme rigidity, and thermal stability. Designed to exceed ISO P4S/P2 tolerance classes, these bearings enable micron-level machining accuracy, high-speed stability, and extended service life in semiconductor manufacturing, aerospace, medical robotics, and ultra-precision machine tools.
