PZ-6202 2RZ Bearing: P6 Precision Performance – The Heart of Electric Drive Systems
The stability of an electric motor directly determines the overall performance, efficiency, and reliability of a vehicle. Designed to meet the demanding requirements of modern electric mobility and industrial automation, the PZ-6202 2RZ Deep Groove Ball Bearing delivers an exceptional balance of load-carrying capacity, high-speed capability, and extended service life.
With dimensions of 15 × 35 × 11 mm, the PZ-6202 is engineered to handle demanding operating conditions. It offers a basic dynamic load rating (Cr) of 7.64 kN and a basic static load rating (C₀r) of 3.72 kN, providing outstanding durability and operational stability under continuous loads.
What truly distinguishes this bearing is its P6 precision grade, manufactured in accordance with international accuracy standards. Combined with a tightly controlled radial internal clearance of 11–18 μm and axial play maintained within 0.08–0.13 mm, the PZ-6202 ensures exceptional rotational accuracy, minimizes vibration, and enhances system stability even at elevated operating speeds.
The bearing is equipped with a specialized 2RZ non-contact seal system constructed from ACM and SPCC materials, specifically designed for demanding environments. This advanced sealing configuration extends the safe operating temperature range up to 140°C, making the bearing suitable for high-temperature applications. The 2RZ seal design provides an optimal balance between protection and performance—effectively retaining the internal PROCON SB-R grease fill (25%–35%) while eliminating friction associated with contact seals. As a result, the bearing can reliably achieve limiting speeds of up to 20,000 RPM.
Applications
Thanks to its superior thermal resistance, high-speed capability, and precision performance, the PZ-6202 2RZ serves as a core component in electric motor drive shafts and gear reduction systems used in electric motorcycles and scooters. The bearing is specifically engineered to withstand the demanding rotational speeds and load variations associated with frequent acceleration and continuous operation.
Beyond electric mobility applications, the PZ-6202 2RZ is an ideal solution for medium-power electric motors, machine tool spindles, laser cutting equipment, industrial ventilation fans, and actuator assemblies within PLC and SCADA automation systems. Its combination of precision, durability, and operational efficiency makes it a critical component for maintaining peak equipment performance and maximizing production uptime.
