6306-2RS/C3 EMS ISB deep groove ball bearing

ISB 6306 2RS C3 EMS Deep Groove Ball Bearing

The ISB 6306 2RS C3 EMS is a high-performance single-row deep groove ball bearing with a reinforced design. This model combines the high load-carrying capacity of the 6300 series with the EMS (Electric Motor Standard), ensuring quiet and stable operation. Equipped with contact rubber seals (2RS), it provides complete protection against dust and moisture, while the increased C3 internal clearance allows for reliable performance at high temperatures, compensating for shaft thermal expansion.

Application

• EMS Grade Electric Motors: Optimized for minimal noise and vibration levels.
• Industrial Pumps and Fans: NBR seals protect the raceways from condensation and grit.
• Gearboxes and Drive Systems: Handling large radial forces in continuous duty cycles.
• Agricultural Equipment: Exceptional durability in mechanisms exposed to extreme contamination.
• Production Machinery: Extended service life thanks to the reinforced steel cage.
