623 2RS MGK Deep Groove Ball Bearing 3x10x4

623 2RS MGK Deep Groove Ball Bearing 3x10x4

623 2RS MGK is a miniature single row deep groove ball bearing designed for compact rotating systems operating at high rotational speeds and under low to moderate radial loads. The 3x10x4 mm bearing configuration is commonly used in precision mechanisms, micro electric motors, lightweight transmission assemblies and miniature industrial equipment requiring low friction and stable rotational accuracy.

Deep groove ball bearings of the 623 series belong to miniature radial bearing solutions used in compact mechanical systems where installation space is limited and smooth rotational behavior is critical. The internal raceway geometry enables stable operation under continuous rotation while maintaining reduced rolling resistance and low vibration levels.

The 623 2RS MGK bearing uses rubber contact seals installed on both sides of the bearing. The 2RS sealing configuration protects the internal rolling elements against:

• dust contamination
• moisture ingress
• grease leakage
• fine industrial particles

Sealed miniature bearings are frequently used in environments where external contamination may affect rotational precision or shorten bearing service life.

The compact dimensions of the 623 2RS MGK bearing make it suitable for:

• miniature electric motors
• precision tools
• small drive assemblies
• laboratory equipment
• electronic devices
• automation systems
• model engineering
• lightweight industrial rollers

Miniature deep groove ball bearings are optimized for low torque operation and stable high speed rotation. Due to the deep raceway profile, the bearing can support radial loads together with moderate axial loads acting in both directions.

The phrase 623 2RS MGK 3x10x4 deep groove ball bearing is frequently searched in servicing applications involving compact industrial drives, precision rotating equipment and miniature transmission systems.
