6203 is a standardized designation for a single-row, deep-groove ball bearing within the 6000 series. These bearings comprise an inner ring, an outer ring, and a cage that accommodates a set of balls.

Specifications

• Dimensions: 17 mm inner diameter, 40 mm outer diameter, 12 mm width
• Type: Single-row, deep-groove ball bearing
• Load Capacity: 2.6 kN dynamic radial, 4.2 kN static radial
• Speed Limit: 15,000 rpm (revolutions per minute)
• Material: Typically high-carbon chromium steel (Gcr15)

Applications of 6203 Bearings

Versatility is a hallmark of 6203 bearings, making them suitable for a wide range of applications:

• Electric motors
• Pumps
• Fans
• Gearboxes
• Conveyor systems
