SKF 626 C3 Deep-Groove Ball Bearing (6x19x6 mm)

Main Description

The SKF 626 C3 is a precision-engineered deep-groove ball bearing tailored for small-diameter and high-speed applications. With dimensions of 6 mm bore, 19 mm outer diameter and 6 mm width, this compact bearing offers a highly efficient solution for constrained assemblies in industrial machinery, gearboxes, and bearing housings.

Featuring a C3 internal clearance, this bearing provides additional space within the raceway to compensate for thermal expansion during operation. This design choice ensures stable performance even under elevated temperatures or high-speed conditions, reducing the risk of binding and promoting reliable rotation.

Constructed from high-grade bearing steel, the SKF 626 C3 offers excellent durability, low friction, and consistent load-handling capability. Its deep-groove profile supports both radial loads and light axial forces, making it adaptable across a wide range of mechanical systems.

This łożysko kulkowe (ball bearing) is especially suitable for bearing units, small electric motors, compact drive trains and other industrial applications that require both high precision and long service life. Its compact size and robust build make it an optimal choice for B2B customers seeking reliable, low-maintenance bearing solutions.

FAQ

Q1: What does the “C3” internal clearance indicate?
A1: C3 means the bearing has larger internal radial clearance than a standard bearing, allowing for thermal expansion and reducing the risk of binding under high-speed or high-temperature conditions.

Q2: Where is a 6x19x6 mm bearing typically used?
A2: This size is common in small electric motors, precision gearboxes, unit bearings, and other compact mechanical assemblies.

Q3: How does deep-groove geometry benefit this bearing?
A3: Deep-groove design allows the bearing to carry both radial and moderate axial loads while maintaining smooth, low-friction rotation.

Q4: What maintenance advantages does this bearing provide?
A4: Because of its small size and robust steel construction, it requires minimal maintenance and can operate reliably in rotating assemblies with tight tolerances.
