Understanding the 6204z Bearing

The 6204z bearing is part of the 6200 series, a widely used group of bearings designed to handle moderate to heavy loads. The "z" suffix denotes a shielded bearing, which incorporates metal shields on both sides to protect the bearing from contaminants and extend its service life.

Key Specifications and Dimensions

The 6204z bearing conforms to the following specifications:

• Bore Diameter: 20 mm
• Outer Diameter: 47 mm
• Width: 14 mm
• Load Capacity: 8.9 kN (radial), 6.0 kN (axial)
• Speed Limit: 12,000 rpm

Material Composition and Construction

6204z bearings are typically manufactured using high-quality steel alloys, which undergo a series of heat treatment processes to enhance their strength and durability. The balls are made of hardened steel, providing excellent wear resistance and low friction. The shields are made of stamped steel, offering effective protection against external contaminants.

Applications and Industries

The 6204z bearing finds applications in a wide range of industries, including:

• Automotive: Transmissions, gearboxes, and wheel hubs
• Aerospace: Flight control systems and landing gear
• Industrial machinery: Electric motors, pumps, and compressors
