Product Description

The F-671163.03.6008 is a precision‑engineered deep groove ball bearing featuring a special slot design and 2RS double‑lip rubber seals, specifically developed for new energy vehicle (NEV) drive motor applications. This bearing is designed to meet the demanding performance requirements of electric and hybrid vehicle traction motors, where high rotational speeds, low noise, low vibration, and long maintenance‑free service life are critical.

Deep groove ball bearings are the most widely used bearing type due to their versatility, low friction, and ability to handle both radial and moderate axial loads in either direction. The F‑671163.03.6008 takes this proven design a step further with a special slot on the outer ring – a feature often used for snap ring or locating ring installation, ensuring secure axial positioning within the motor housing. The 2RS seals on both sides provide excellent protection against dust, moisture, and lubricant leakage, making this bearing ideal for sealed motor assemblies where contamination resistance is paramount.

Manufactured from GCr15 chrome steel with precision‑ground raceways and balls, this bearing delivers superior wear resistance, dimensional stability, and fatigue strength under the high‑speed, high‑temperature conditions typical of NEV drive motors. The steel cage ensures reliable ball guidance and low heat generation, while precision grades P0, P6, and P5 are available to match the stringent tolerance requirements of modern electric drivetrains.

Key Features & Specifications

Why Choose This Bearing?

• NEV Drive Motor Optimised – Designed specifically for the high‑speed, high‑temperature, and low‑noise requirements of electric vehicle traction motors, ensuring smooth operation and extended service life.

• Special Slot Design – The outer ring slot allows for secure axial positioning via snap rings or locating rings, simplifying motor assembly and preventing axial displacement under dynamic loads.

• 2RS Sealed for Contamination Protection – Double‑lip rubber seals effectively retain lubricant and keep out dust, moisture, and other contaminants – critical for sealed motor units that require long‑term, maintenance‑free operation.

• High‑Speed Capability & Low Noise – Precision‑ground raceways and high‑quality steel balls ensure low friction, reduced vibration, and quiet running, meeting the NVH (Noise, Vibration, Harshness) standards demanded by modern electric drivetrains.

• Flexible Precision Options – Available in P0, P6, and P5 accuracy grades, allowing selection based on the specific speed and tolerance requirements of the motor assembly.
