6203-2RSH/C3 SKF deep groove ball bearing

SKF 6203-2RSH/C3 Deep Groove Ball Bearing

The SKF 6203-2RSH/C3 is a high-performance deep groove ball bearing engineered for reliability under demanding thermal and environmental conditions. It features advanced 2RSH contact seals made of NBR rubber for superior protection against contaminants. The C3 internal clearance is a critical feature that allows for thermal expansion of the shaft or housing, making this bearing essential for high-speed applications and electric motors.

Application

• Electric Motors & Alternators: Stable operation at high temperatures and rotational speeds.
• Industrial Pumps & Fans: Resistance to moisture and stability during continuous duty.
• Household Appliances: Used in washing machines and other equipment requiring low noise levels.
• Agricultural Machinery: Protection against heavy dust and dirt via the RSH seal.
• Compressors: Accommodates operational heat through C3 clearance.

Technical Specification

• Manufacturer: SKF (Sweden)
• Designation: 6203-2RSH/C3
• Dimensions: 17 mm (ID) x 40 mm (OD) x 12 mm (Width).
• Sealing: 2RSH – contact seals on both sides.
• Internal Clearance: C3 – greater than normal.
• Lubrication: Factory greased for life (maintenance-free).

Features and Benefits

• Enhanced Thermal Tolerance: C3 clearance prevents seizure when machine components heat up during use.
• Premium Sealing: RSH seals are more effective at grease retention and exclusion of water than standard 2RS designs.
• Extended Service Life: High-purity steel reduces fatigue and wear on the raceways.
• Plug-and-Play: Ready for immediate installation with optimal factory lubrication.
• Quiet Operation: Precision-ground raceways minimize vibration and acoustic emissions.

Why Choose This Product

Investing in the SKF 6203-2RSH/C3 means investing in operational uptime. Unlike standard bearings, the C3 clearance version compensates for thermal expansion, preventing sudden drive failures. The highly effective RSH sealing makes this a "fit and forget" solution, leading to significant long-term savings by eliminating unplanned maintenance and machine downtime.
