6008-2Z Deep Groove Ball Bearing For Versatile Performance & Reliable Operation | 40×68×15 mm

The 6008-2Z is a Standard Shielded Deep Groove Ball Bearing from the popular 60-series, designed to handle moderate radial and axial loads in both directions with efficiency and quiet operation. Its double metal shield (2Z) configuration provides effective protection against dust and contaminants while retaining lubrication, making it a maintenance-friendly solution for a wide array of applications. With a 40 mm bore, 68 mm outer diameter, and 15 mm width, this bearing is a common choice for electric motors, automotive components, and general machinery where dependable, high-speed performance is required.



6008-2Z Deep Groove Ball Bearing 40×68×15mm | ISO 60 Series – General Purpose | Double Shielded (2Z)

Engineered for smooth, high-speed rotation, the 6008-2Z features a quiet-running deep groove raceway and a robust steel cage. It offers a dynamic load rating of 17.8 kN, providing reliable load capacity for continuous operation in light industrial and mechanical applications . The non-contact metal shields on both sides serve as effective seals against larger particles and help preserve the factory-applied grease, reducing maintenance needs and extending service life in clean operating environments.

Key Performance Features

01. Application-Specific Configuration Flexibility

While the standard 6008-2Z is optimized for general industrial use, alternative configurations including C3 radial clearance (for higher operating temperatures), P5 precision grades (for tighter running accuracy), and specialized high-temperature greases are available upon request to meet specific equipment requirements.

02. Factory Pre-Greased for Maintenance-Free Operation

Supplied pre-lubricated with high-quality lithium-based grease, the double shielded design retains lubrication effectively throughout the bearing's service life. The non-metal shields protect the grease from contamination while allowing excess lubricant to escape during initial running-in, ensuring optimal lubrication conditions without the need for relubrication.

03. Low Friction Operating Design

The 6008-2Z incorporates a low-friction internal configuration that reduces heat generation and mechanical losses during high-speed rotation. By minimizing contact resistance between the balls and raceways, this design contributes to improved energy efficiency and cooler running temperatures in applications such as electric motors and power tools.

Design & Configuration

The standard 6008-2Z is supplied as a double-shielded bearing, pre-lubricated with high-quality grease for maintenance-free operation . For applications requiring a higher level of sealing against moisture and fine particulates, sealed variants such as 6008-2RS (double rubber contact seals) are available. An open version (6008) is also offered for applications with unique relubrication requirements or custom housing seals.

"As a compact and efficient member of the 60-series, the 6008-2Z deep groove ball bearing is the preferred choice for engineers designing electric motors, pumps, and light industrial drives where reliable, high-speed operation and low maintenance are critical."
