P5 Z3V3 Silence Ball Bearing For High Quality Pumps, Pump Motors
The Stainless Steel P5 Bearing C3 Low Noise Bearing 6205 is a high-precision, corrosion-resistant bearing designed for demanding applications such as pumps and water pumps. Available in three variants—6205ZZ (double metal shields), 6205-2RS (double rubber seals), and open type—this bearing is engineered to deliver exceptional performance in environments where corrosion resistance, low noise, and high precision are critical. The P5 precision grade ensures smooth and quiet operation, while the C3 internal clearance makes it suitable for high-speed or high-temperature applications. Its stainless steel construction provides excellent resistance to rust and corrosion, making it ideal for use in water pumps and other wet or corrosive environments.
Type: Single Row Deep Groove Ball Bearing
Material: Stainless Steel (corrosion-resistant)
Precision Grade: P5 (high precision for smooth and quiet operation)
Internal Clearance: C3 (greater than standard, suitable for high-speed or high-temperature applications)
Variants:
6205ZZ: Double Metal Shields (dustproof)
6205-2RS: Double Rubber Seals (dustproof and water-resistant)
Open Type: No shields or seals (for specific applications)
Load Capacity: Handles both radial and axial loads
Application Focus: Pumps, water pumps, and other corrosive or wet environments
Corrosion Resistance: Made from stainless steel, the bearing is highly resistant to rust and corrosion, making it ideal for water pumps and other wet environments.
Low Noise Operation: The P5 precision grade ensures smooth and quiet operation, reducing noise in sensitive applications.
High-Speed Capability: The C3 internal clearance allows for reliable performance in high-speed or high-temperature conditions.
Versatile Protection Options:
6205ZZ: Double metal shields for dustproof protection.
6205-2RS: Double rubber seals for dustproof and water-resistant protection.
Open Type: For applications where shields or seals are not required.
Durability: Stainless steel construction ensures long service life, even in harsh or corrosive environments.
The 6205 bearing has the following standard dimensions:
| Parameter | Value (mm) |
|---|---|
| Inner Diameter (d) | 25 mm |
| Outer Diameter (D) | 52 mm |
| Width (B) | 15 mm |
