624ZZ 624-2RS 624 Deep Groove Ball Bearing 4x13x5mm

624ZZ and 624-2RS deep groove ball bearings, with an inner diameter of 4mm, outer diameter of 13mm, and width of 5mm. The former features metal dust shields on both sides, while the latter has rubber seals on both sides. Both bearings exhibit low friction and high rotational speed characteristics, capable of withstanding radial loads and minor axial loads. They are suitable for precision instruments, small motors, and similar equipment.

Technical parameter:

The 624 series (including 624ZZ, 624-2RS, and the base model) deep groove ball bearings feature a standardized design and adaptability, specifically:

Unified Core Structure: All models adopt the classic deep groove configuration comprising an inner ring, outer ring, single row of steel balls, and a cage. The raceways feature an arc-shaped deep groove, enabling simultaneous handling of radial loads and limited bidirectional axial loads to accommodate diverse load requirements.

Differentiated Sealing Types: The 624ZZ features dual-sided metal dust shields, offering stable dust resistance and good temperature tolerance; The 624-2RS features dual rubber seals for superior sealing, minimizing grease leakage and blocking liquid ingress; the unsealed base model suits clean, low-contamination environments.

Compact Dimensions: Adhering to specifications of 4mm inner diameter, 13mm outer diameter, and 5mm width, the compact design accommodates small equipment with stringent installation space requirements.
