Deep groove ball bearing:607zz

Description

Basic Parameters

In bearing 607ZZ, “6” denotes the 6 – series deep – groove ball bearing, “0” is the size series, and “7” indicates an inner diameter of 7mm. The “ZZ” suffix means it has two sealed steel shields. As a standard part, its dimensions are: outer diameter 19mm, height 6mm, and inner diameter 7mm. It contains 7 steel balls, each with a diameter of 3.175mm. The basic dynamic load rating is 2.25 kN, and the basic static load rating is 0.97 kN. The limit speed is 30000 r/min for grease lubrication and 38000 r/min for oil lubrication. Its mass is around 0.007 kg. There’s no direct equivalent for its old model number in the current system. Standard 607ZZ bearings are widely available on the market.

Features and Performance

• Radial and Axial Load Bearing: This bearing can withstand both radial and a certain amount of axial loads simultaneously. It is suitable for applications where combined loads are present.
• Good Rotational Smoothness: The deep – groove design and high – quality rolling elements ensure smooth rotation, reducing friction and vibration during operation.
• Sealed Structure: The two metal shields (ZZ) effectively prevent dust, dirt, and other contaminants from entering the bearing, extending its service life and maintaining its performance in dirty environments.

Materials and Construction

• Bearing Steel Material: The rings and balls of the bearing are usually made of bearing steel such as GCr15. This material offers excellent hardness, wear resistance, and fatigue resistance, ensuring reliable operation under various loads.
• Cage Material: The cage is commonly made of engineering plastics or metal. Engineering plastic cages are lightweight and have good self – lubricating properties, while metal cages offer higher strength and can withstand more severe operating conditions. The cage is used to separate and guide the rolling elements, ensuring their even distribution and smooth movement.
• Deep – Groove Design: The deep – groove structure of the inner and outer rings provides a large contact area between the balls and the rings, enhancing the bearing’s load – carrying capacity and allowing for stable operation at high speeds.

Product Application

Small – scale Electrical Equipment: Such as electric fans, small – power motors, and cooling fans in electronic devices. People choose it for these space – limited applications because of its small size and its ability to handle both radial and axial loads.

Precision Instruments: For example, in measuring instruments, optical equipment, and small – scale machine tools. The smooth rotation and high – precision performance of the bearing ensure the accuracy of these instruments.

Office Equipment: In printers, scanners, and copiers. The sealed structure of the 607ZZ bearing protects against dust generated during the operation of these devices, maintaining their normal operation.In summary, the 607ZZ deep – groove ball bearing is a reliable and versatile bearing suitable for a wide range of applications that require both radial and axial load – bearing capabilities, smooth rotation, and protection against contaminants.
