6204-2Z/C3 SING ISB deep groove ball bearing

ISB 6204 ZZ/C3 Deep Groove Ball Bearing (SING)

The ISB 6204 ZZ/C3 is a high-performance single-row deep groove ball bearing, offering a perfect balance between radial load capacity and high-speed efficiency. Featuring dual metal shields (ZZ), it provides non-contact protection against contaminants, allowing for maximum rotational speeds with minimal heat generation. The increased C3 internal clearance makes it ideal for applications subject to thermal expansion of the shaft. The SING designation ensures delivery in original single-unit ISB packaging.

Application

• Electric Motors & Alternators: C3 clearance prevents ball seizing during rotor thermal expansion.
• High-Speed Fans: ZZ shields do not impede rotation, allowing for smooth, friction-free performance at high RPMs.
• Power Tools: Durability and stability in the compact 6200 series form factor.
• Gearboxes & Drives: Precision shaft guidance under radial loads.
• Agricultural Equipment: Proven construction for auxiliary mechanical units.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6204 ZZ/C3
• Type: Single-row deep groove ball bearing.
• Sealing: ZZ – non-contact metal shields on both sides.
• Internal Clearance: C3 – radial clearance greater than normal.
• Maintenance: Factory pre-greased (maintenance-free).

Note: Standard dimensions for the 6204 model are 20 mm (Bore) × 47 mm (OD) × 14 mm (Width).

Features and Benefits

• High-Speed Efficiency: Absence of contact friction on the seals enables operation at peak limiting speeds.
• Thermal Stability: C3 class eliminates risk of failure due to temperature gradients between bearing rings.
• Low Energy Consumption: Minimized rolling resistance leads to lower power draw by the machine.
• ZZ Protection: Effective barrier against solid debris without increasing the friction torque.
• ISB Quality Standards: Precision manufacturing ensuring quiet and stable operation.
