PZ-6201 2RZ Bearing: Optimized Speed – A Smooth Power Transmission Solution for Electric Vehicles
Are you looking for a compact power transmission solution that can still deliver outstanding performance at high rotational speeds? The PZ-6201 2RZ Deep Groove Ball Bearing is the ideal choice for automated machinery and next-generation mobility applications, including electric motorcycles and scooters.
With its standard dimensions of 12 × 32 × 10 mm, the PZ-6201 is specifically designed for space-constrained applications. The bearing rings and rolling elements are manufactured from premium GCr15 bearing steel, featuring a hardness range of 61–64 HRC. This robust construction provides a basic dynamic load rating (Cr) of 6.80 kN and a basic static load rating (C₀r) of 3.05 kN, ensuring reliable performance under demanding operating conditions.
One of the key advantages of the PZ-6201 2RZ is its 2RZ non-contact seal design, manufactured from high-quality NBR/SPCC materials. Unlike conventional 2RS contact seals, which create additional friction by making direct contact with the inner ring, the 2RZ seal incorporates a precisely engineered micro-clearance. This design effectively prevents dust contamination, retains lubricant inside the bearing, and virtually eliminates rotational resistance. As a result, the bearing can achieve exceptionally high operating speeds while maintaining smooth and efficient performance.
From an operational control perspective, the radial internal clearance of the PZ-6201 2RZ is tightly controlled within a range of 3–18 μm. Combined with an operating temperature range of –30°C to 120°C, the bearing delivers excellent vibration and noise control, making it well-suited for applications where quiet operation and precision performance are essential.
Applications
Thanks to its ability to operate smoothly at high speeds with low torque resistance, the PZ-6201 2RZ is an excellent choice for front and rear wheel hub assemblies of electric motorcycles and scooters, as well as auxiliary mechanisms that require high rotational speeds.
The bearing is also widely suited for precision automation equipment, servo motors, light-duty conveyor systems, and measurement devices such as CNC probes and sensors. Its combination of durability, efficiency, and low-maintenance operation makes it a smart investment for manufacturers seeking to reduce downtime, extend equipment service life, and improve overall system reliability.
