SKF 624‑2RS | Miniature Deep Groove Ball Bearing 4x13x5 mm - Double Rubber‑Sealed

SKF 624‑2RS | Miniature Deep Groove Ball Bearing 4x13x5 mm - Double Rubber‑Sealed

The SKF 624‑2RS is a high-performance miniature deep groove ball bearing tailored for compact and precision-driven applications:

• Dimensions: Bore = 4 mm, Outer diameter = 13 mm, Width = 5 mm

• Sealing: Double contact rubber seals (2RS) - prevents dust, grease loss and ensures reliable lubrication

• Design: Single‑row deep groove - supports radial loads and moderate axial loads with minimal friction

• Build Quality: High-grade bearing steel and sheet steel cage; compact yet durable

• Speed & Performance: Operates quietly at high speeds; Pre-greased for maintenance-free use

• Temperature Range: -20 °C to +120 °C — suitable for diverse industrial environments

Ideal for industries requiring compact, efficient, and reliable mini bearings.

Applications

• Small electric motors, dental/medical devices

• Robotics, drones, and RC equipment

• Printers, scanners, and office automation

• Hand tools, instrument mechanisms

FAQ - Frequently Asked Questions

Q1: What does “2RS” mean?
SKF’s 2RS seal stands for two contact rubber seals—one on each side—to retain grease and protect against contaminants.

Q2: Can it handle axial loads?
Yes — the deep groove design supports radial and light axial loads in both directions.

Q3: What temperature range is it rated for?
Reliable between -20 °C and +120 °C, covering most industrial or precision environments.

Q4: Is it maintenance-free?
The pre-filled lubrication and sealed design reduce the need for maintenance under normal conditions .

Q5: What applications suit this bearing?
Best for compact, high-speed, and precision applications like small motors, robotics, office machinery, and hand tools.
