F-624970.02.KL-H79 30X80X21mm New Energy Auto Bearings Ball Bearings

Product Introduction: F-624970.02.KL-H79 30×80×21mm New Energy Automotive Ball Bearing

The F-624970.02.KL-H79 is a precision-engineered single‑row deep groove ball bearing, specifically developed for the evolving demands of new energy vehicles (NEVs). With dimensions of 30 mm inside diameter × 80 mm outside diameter × 21 mm width, this bearing offers a robust, compact solution for high‑speed, high‑temperature drivetrain environments.

Key Technical Specifications:

• Model: F-624970.02.KL-H79

• Dimensions: 30×80×21 mm

• Structure: Single‑row deep groove ball bearing

• Internal Clearance: C3 – optimised for thermal expansion and high‑speed rotation

• Precision Rating: P0 (standard industrial grade)

• Seals Type: 2RS (double‑sided rubber seals) – providing excellent protection against dust, moisture, and contaminant ingress

• Seal Material: Rubber seals – ensuring reliable sealing performance over extended service intervals

• Load Direction: Supports combined axial and radial loads

• Cage: Nylon (polyamide) – lightweight, low‑noise, and highly wear‑resistant

Materials:

• Rings & Balls: GCr15 chrome steel – offering superior hardness, fatigue strength, and dimensional stability

• Cage Material: Nylon – reduces friction and rotational inertia for smoother operation

Performance & Feature Highlights:
Although designed as a standard deep‑groove configuration, this model incorporates non‑standard internal geometry to deliver enhanced rigidity and shock resistance required in electric drivetrains. The C3 clearance ensures stable performance under varying thermal and load conditions, while the 2RS rubber seals provide a maintenance‑friendly, grease‑retained design that effectively extends bearing life in challenging under‑hood environments. The nylon cage minimises noise and vibration, contributing to quieter vehicle operation.

Primary Applications:
Specifically developed for new energy vehicles (electric and hybrid passenger cars), this bearing is ideally suited for:

• Electric drive unit (EDU) transmission systems

• Reduction gearboxes

• Differential assemblies

• Auxiliary motor shafts and other high‑speed rotating components in NEV powertrains
