6304-ZZ PFI Deep Groove Ball Bearing Shield (ID 20mm OD 52mm W 15mm)

The PFI 6300 series deep groove ball bearings are designed for reliable performance in a wide range of industrial and mechanical applications. Manufactured to precise tolerances, these bearings provide consistent operation under both radial and axial loads, making them suitable for use in general engineering, transmission, and machinery assemblies where dependable motion control is required.

Product Overview

PFI 6300 deep groove ball bearings consist of an inner ring, an outer ring, a series of precision steel balls, and a cage that maintains spacing and smooth rotation. These bearings are constructed from high-grade bearing steel and are engineered to deliver durability and dimensional stability under continuous service conditions. Their internal design and surface finishes optimise load distribution and minimise friction during operation.

Design Features

The 6300 bearing series features a deep raceway geometry that allows for the accommodation of radial and moderate axial loads in both directions. The cages are manufactured to maintain precise ball spacing, enhancing smooth motion and reducing vibration at higher speeds. Sealed or shielded variants may be available to protect against contamination and retain lubricant within the bearing assembly. The internal clearance and tolerances are maintained in accordance with international bearing standards to ensure interchangeability and consistent fit in housings or shafts.

Functional Characteristics

These bearings are designed to operate efficiently across a range of speeds and temperatures, depending on lubrication type and load conditions. The optimised internal design contributes to low frictional torque, reduced noise during operation, and extended service life. Proper lubrication and sealing enable stable performance even in environments where exposure to dust or moisture may occur.

Use in Assemblies

PFI 6300 deep groove ball bearings are commonly used in electric motors, agricultural machinery, conveyor systems, industrial gearboxes, and other mechanical assemblies that require reliable rolling motion support. They are typically installed in both fixed and free bearing positions and can be paired with matching housings or shafts for balanced load carrying. The robust design ensures stable operation and ease of replacement during maintenance cycles.
