6304-2Z/C2ELHT23

• 6304: Basic model number indicating a medium-duty, metric deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width.
• 2Z: Designates that the bearing is shielded on both sides. These non-contact shields protect the internal components from contamination by solid particles while minimizing friction, contributing to a high limiting speed.
• C2: Indicates a radial internal clearance that is smaller than the Normal (CN) group. This is beneficial for applications requiring precise shaft positioning, reduced noise, and operation where thermal expansion is minimal.

The single row deep groove raceway geometry is fundamental to its high radial dynamic load rating of 3574 lbf. Constructed entirely from Chrome Steel for the rings, balls, and cage, the bearing ensures high strength, durability, and resistance to wear. The shielded (2Z) design effectively excludes contaminants, extending service life and enabling a high limiting speed of 14,000 rpm. The C2 clearance provides optimal preload conditions in precision assemblies, resulting in smooth, quiet operation and enhanced rigidity. Manufactured to ABEC 1 | ISO P0 tolerance class, it guarantees consistent quality and dimensional accuracy for reliable performance.

This versatile bearing is widely used across various industries due to its balanced performance characteristics. Common applications include:

• Electric Motors and small machinery
• Gearboxes and transmission systems
• Pumps and compressors
• Agricultural machinery
• Material handling equipment
• Automotive components (e.g., alternators, idler pulleys)
