6203-2RS/C3 SING ISB deep groove ball bearing

ISB 6203 2RS/C3 Deep Groove Ball Bearing (SING)

The ISB 6203 2RS/C3 is a high-performance single-row deep groove ball bearing, engineered for versatility and long service life. Part of the 6200 series, it offers an optimal balance between radial load capacity and compact dimensions. Equipped with contact rubber seals (2RS), it provides total protection against dust and moisture. The increased C3 internal clearance makes it ideal for high-speed applications and electric motors where thermal expansion of the shaft is expected.

Application

• Electric Motors & Alternators: C3 clearance prevents ball seizing during rotor thermal expansion.
• Power Tools: Grinders, drills, and saws – high resistance to dust and grit.
• Home Appliances: Washing machines, vacuum cleaners, and mixers – ensures quiet operation.
• Pumps and Fans: NBR seals protect the lubricant from moisture and condensation washout.
• Light Mechanical Drives: Precision shaft guidance in automation systems.
