Description

Steel Ball Bearing 1/4" Bore 1/4x5/8x5mm Double Shielded Miniature ZZ

This is a single miniature steel radial ball bearing with a 1/4" (6.35 mm) bore, 5/8" (15.875 mm) outer diameter, and 5 mm width. Both sides are fitted with metal shields (ZZ configuration) to keep lubricant in and contaminants out. This size corresponds to the standard designation R2ZZ and is a commonly used miniature bearing across many mechanical applications.

Specifications & What's Included

  • Type: Single row deep groove miniature ball bearing
  • Bore (Inner Diameter): 1/4" (6.35 mm)
  • Outer Diameter: 5/8" (15.875 mm)
  • Width: 5 mm
  • Shielding: Double shielded, both sides (ZZ)
  • Material: Steel
  • Standard Designation: R2ZZ
  • Quantity: 1 (single unit)

Applications

Miniature ball bearings in the R2ZZ form factor are widely used in small mechanical and electromechanical assemblies where compact, low-friction rotational support is needed. Common applications include 3D printers, RC vehicles and hobby models, small electric motors, fans, rollers, linear motion systems, and light industrial machinery. The double-shield construction makes them a practical choice in environments where some protection from dust or light debris is needed without the use of a sealed rubber contact seal. This size has been a standard in precision mechanical design for decades and remains in active production and widespread use today.

Condition: Used
This steel miniature double-shielded ball bearing (1/4" bore x 5/8" OD x 5mm wide) has been inspected and is in good used condition. The bearing shows light surface wear consistent with prior use but retains its shape and both metal shields are intact with no visible damage. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
