608ZZ bearing

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

The 608Z bearing, also known as the 608-Z bearing, is a single-row deep groove ball bearing with a single shield. Here is a detailed introduction in English:

1. Design and Features:

• The 608Z bearing is a deep groove ball bearing with a single row of balls, which is known for its versatility, low friction, and optimization for low noise and vibration. This design enables high rotational speeds and accommodates both radial and axial loads in both directions. It is easy to mount and requires less maintenance compared to many other bearing types. The integral shield significantly prolongs bearing service life by keeping lubricant in the bearings and contaminants out.

2. Dimensions and Specifications:

• The 608Z bearing has an inner diameter (d) of 8mm, an outer diameter (D) of 22mm, and a width (B) of 7mm.

• The bearing has a basic dynamic load rating of 3.45 kN and a basic static load rating of 1.37 kN.

• The reference speed is 75,000 r/min, and the maximum speed (limiting speed) is 48,000 r/min.

• The bearing clearance is identified as CN, which indicates normal radial clearance.

3. Performance:

• The 608Z bearing is optimized for low noise and low vibration, which are critical for high-speed applications.

• It is manufactured from bearing steel, and the rolling elements are also made of steel. The cage is made of sheet steel, contributing to its durability and performance.

4. Applications:

• The 608Z bearing is widely used in various industries such as automotive, machine tools, marine, railway, printing and storage energy machines, cake shop equipment, single-stage pumps, vibrating dryers, quilting machines, wear-resistant pumps, agricultural machine parts, machine tool lighting, standard screens, dump trucks, pattern making machines, worm gear reducers, tubular reactors, vibration testing machines, coking equipment, foaming equipment, high-purity water production equipment, Heidelberg printing machines, cycloidal reducers, absorbers, oral liquid pharmaceutical equipment, nail heel machines, packaging auxiliary equipment, winches, presses, medical, and food industries.

5. Maintenance:

• The 608Z bearing requires little maintenance, which is an advantage in many industrial applications where reducing downtime and maintenance costs is crucial.

6. Variants:

• There are variants of the 608Z bearing with different sealing options, such as single shield or double shield, which can significantly prolong the bearing service life by keeping lubricant in the bearings and contaminants out.

This comprehensive overview of the 608Z bearing highlights its key features, performance specifications, and wide range of applications, making it a popular choice in various mechanical engineering fields.
