PFI 6205 2RS 1" Deep Groove Ball Bearing (25.4x52x15 mm)

Applications of PFI 6205 2RS 1" Bearing

The PFI 6205 2RS 1" (25.4x52x15 mm) is a deep groove ball bearing designed for both metric and imperial shaft systems, featuring a 1-inch (25.4 mm) bore. It is widely used in industrial machinery, electric motors, agricultural equipment, conveyors, and gearboxes, where reliability, precision, and low noise are essential. The bearing’s robust construction and tight sealing make it suitable for demanding industrial and automotive applications, offering long-lasting performance under radial and axial loads.

Key Features and Benefits

The PFI 6205 2RS 1" bearing is part of PFI’s precision-engineered series, delivering smooth rotation, high load capacity, and excellent protection against contamination.

Main advantages:

• Double rubber seals (2RS): prevent dust, moisture, and contaminants from entering.

• C3 internal clearance: allows better performance at high speeds and elevated temperatures.

• High-grade bearing steel: ensures durability and dimensional stability under heavy loads.

• Pre-lubricated design: filled with long-life lithium-based grease for maintenance-free operation.

• Universal interchangeability: compatible with ISO-standard bearings, equivalent to models from SKF, NSK, FAG, NTN, and KOYO.

This bearing’s combination of precision and resilience makes it a preferred choice for OEMs and maintenance engineers seeking optimal performance in both metric and inch-based applications.
