6011-2RS/C3 SING ISB deep groove ball bearing

ISB 6011 2RS C3 Deep Groove Ball Bearing (SING)

The ISB 6011 2RS C3 is a high-performance single-row deep groove ball bearing designed for versatile industrial and mechanical applications. Its robust design efficiently handles radial loads and moderate axial loads in both directions. Featuring low-noise operation and high durability, this model is a staple in precision engineering. The SING designation ensures the product is delivered in its original, single factory package for maximum protection.

Application

• Electric Motors: C3 clearance accommodates thermal expansion of the shaft during continuous operation.
• Industrial Pumps and Fans: Superior protection against moisture and dust due to dual 2RS seals.
• Gearboxes and Drives: Stable performance in medium-to-heavy-duty transmission systems.
• Agricultural Machinery: Protection against field contaminants, dirt, and debris.
• Manufacturing Equipment: Long service life and reduced maintenance intervals in production lines.
