Industry knowledge

1.Precision Grade P4 and Material Composition
The Radial Angular Contact Ball Bearing 7000C SU, with its precision grade of P4, is engineered to deliver outstanding accuracy and reliability in various industrial settings. The designation of P4 indicates a high level of precision in the manufacturing process, ensuring consistent performance, reduced vibration, and minimal noise generation during operation. This level of precision is vital, especially in applications where rotational speed and load-bearing capacities are critical factors.
The choice of GCr15 as the primary material for this bearing holds immense significance. GCr15 is a high-quality chromium steel known for its exceptional hardness, strength, and resistance to wear and fatigue. Its composition makes it well-suited for bearing applications, enabling the 7000C SU to withstand heavy loads, high speeds, and harsh operating conditions without compromising its structural integrity. Furthermore, GCr15's resistance to corrosion ensures prolonged service life, making it a reliable choice for demanding industrial environments.

2.Cage Types: PA66 and PA46
The Angular Contact Ball Bearing 7000C SU comes with two cage variations: PA66 and PA46. These cages, made from high-quality polyamide, are designed to support the bearing's functionality under different operating conditions.
PA66, known for its excellent mechanical properties, including high strength and heat resistance, provides the bearing with enhanced stability, especially in high-speed applications. Its ability to maintain structural integrity at elevated temperatures makes it suitable for environments where heat generation is a concern.
On the other hand, PA46, characterized by its superior wear resistance and low friction coefficients, ensures efficient ball guidance within the bearing. This results in reduced heat generation and energy consumption, contributing to the bearing's overall performance and longevity.
