62309-2RS-C3 PFI Deep Groove Ball Bearing Sealed C3 Clearance (ID 45mm OD 100mm W 36mm)

The PFI 62300 Series Deep Groove Ball Bearing is designed for use in a wide range of industrial and mechanical applications where reliable radial and axial load support is required. It belongs to PFI’s precision-engineered bearing range, known for consistent quality and dimensional accuracy. This series provides dependable performance under varying operating conditions and speeds, making it well-suited to demanding power transmission and machinery environments.

Product Overview

The 62300 Series Deep Groove Ball Bearing is a single-row bearing type featuring a simple yet robust internal construction. It is designed to accommodate moderate radial and axial loads in both directions. Manufactured from high-grade bearing steel, the component offers controlled internal geometry and optimised surface finish to reduce friction and ensure consistent performance. The design balances high load capacity with smooth, quiet running, resulting in improved efficiency across rotational systems.

Design Features

Each bearing within the 62300 series incorporates deep raceway grooves with closely matched curvature to the rolling elements, providing excellent alignment stability and load distribution. The internal design supports high-speed operation while maintaining minimal vibration. Depending on the configuration, the bearings may be supplied with open, shielded, or sealed closures to protect against contamination and retain lubricant. Precision manufacturing tolerances further contribute to reduced operating noise and extended service life.

Functional Characteristics

In use, the PFI 62300 Series bearing delivers reliable rotation with low frictional resistance and controlled heat generation. It withstands moderate axial loading in both directions while maintaining rigidity under radial stress. The steel cage ensures secure ball separation, promoting uniform load transfer and minimising wear on running surfaces. Its balanced internal clearance supports smooth operation even in applications involving thermal expansion or shaft misalignment within design limits.

Use in Assemblies

The 62300 Series Deep Groove Ball Bearing is commonly used in electric motors, agricultural equipment, gearboxes, conveyors, and general industrial machinery. Its compatibility with standard housings and shafts allows straightforward integration into existing assemblies. Due to its high-speed capability and durability, it suits environments where consistent rotational performance and extended maintenance intervals are essential. Proper alignment and lubrication further enhance bearing longevity in service conditions.
