608Z Double Row Deep Groove Ball Bearings

608Z Double Row Deep Groove Ball Bearings are precision-engineered rolling bearings designed for high-speed, low-noise, and long-life applications. Compared with single-row bearings, the double-row structure provides higher load capacity and improved stability, making them ideal for demanding industrial and mechanical environments.

As a professional China manufacturer and supplier, Hengji Bearing delivers reliable and cost-effective bearing solutions to global buyers, distributors, and OEM customers. Our factory ensures strict quality control and consistent performance across every batch.

What is 608Z Double Row Deep Groove Ball Bearings?

The 608Z Double Row Deep Groove Ball Bearings is a compact radial bearing with double rows of steel balls and metal shields (Z type) on one or both sides. The shield protects the bearing from dust and debris while retaining lubricant, ensuring smooth operation.

Key Functions:

●Support radial and limited axial loads

●Reduce friction between moving parts

●Enable high-speed rotation

●Improve equipment efficiency and lifespan

Bearing preservation

Bearings are precise parts. In order to maintain the accuracy and reliability of bearings, they must be handled carefully during operation, especially to keep the bearings clean and avoid strong collisions and rust.

The 608Z Double Row Deep Groove Ball Bearings produced by the company are all attached with rust inhibitors on the surface and should be stored at room temperature with a relative humidity below 60%.

Precautions for use

When starting at low temperatures or when the grease viscosity is very high, a larger minimum load may be required. The weight of the bearing, plus the external force, usually exceeds the required minimum load. If the minimum load has not yet been reached, the bearing must be subjected to an additional radial load.

FAQ

Q1: What is the difference between 608Z and 608ZZ?

608Z usually has a single metal shield, while 608ZZ has shields on both sides for better sealing and protection.

Q2: Can this bearing handle axial loads?

Yes, but primarily designed for radial loads. It can support light axial loads in both directions.

Q3: Is lubrication required?

No. The bearing comes pre-lubricated, but additional lubrication can extend service life in heavy-duty applications.

Q4: Can I customize the bearing?

Yes. As a professional China factory, Hengji Bearing supports:

Custom materials

Precision grades

Packaging & branding (OEM)
