Understanding 6203 2RS Bearings

Definition

A 6203 2RS bearing is a single-row deep groove ball bearing with a metric bore diameter of 17 mm, an outer diameter of 40 mm, and a width of 12 mm. The designation "2RS" indicates the presence of two rubber seals on both sides of the bearing, protecting it from contaminants and retaining lubricant within.

Construction

6203 2RS bearings are typically manufactured using chrome steel for the inner and outer rings, balls, and cage. The seals are made from nitrile rubber or polyacrylate, providing excellent resistance to heat, oil, and dust.

Characteristics

• Bore diameter: 17 mm
• Outer diameter: 40 mm
• Width: 12 mm
• Cage type: Stamped steel or machined brass
• Load capacity: Radial: 5.62 kN, Axial: 2.81 kN
• Speed limit: 12,000 rpm (oil lubricated)
• Operating temperature range: -20°C to +120°C

Applications

6203 2RS bearings find widespread use in various industries, including:

• Automotive: Gearboxes, transmissions, pumps, idlers
