6303 SING ISB deep groove ball bearing

ISB 6303 Deep Groove Ball Bearing (SING)

The ISB 6303 is a reinforced single-row deep groove ball bearing from the 6300 series. This model features larger rolling elements and more robust rings than standard light series, enabling it to handle significantly higher radial loads. Its open design ensures minimal friction, making it an excellent choice for high-speed, oil-lubricated applications. The SING designation guarantees delivery in the original single-unit factory packaging.

Application

• Gearboxes and Transmissions: Ideal for oil-bath environments requiring high load ratings.
• Electric Motors: Applications focused on high energy efficiency and low rolling resistance.
• Pumps and Fans: Reliable shaft guidance with minimal vibration levels.
• Agricultural Machinery: Drive systems requiring heavy-duty and wear-resistant components.
• Industrial Equipment: Mechanisms operating under constant, high radial stress.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6303
• Type: Deep groove ball bearing (Open)
• Design: Single-row
• Series: 6300 – High load capacity
