What are the main types of deep groove ball bearing？

1. Ball Bearing 6000 ZZ

Deep groove ball bearing open type is a type of ball bearing characterized by simple structure, convenient use, and it is the most commonly produced and widely used type of bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set cages. It can be designed as a single or double row and is divided into sealed and open structures. Open type deep groove ball bearings do not have a seals, which is allowing simple prevention of dust from entering the bearing raceway. They are suitable for various high-speed rotating fields and have the advantages of high speed and long service life. ‌

2. Ball Bearing 6000 Open

Open deep groove ball bearings are suitable for high-speed or even extremely high speed operation, and they are very durable without frequent maintenance. This type of bearing has a low friction coefficient, high maximum speed, diverse size range and form variations, and is widely used in industries such as precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. It is the most widely used type of bearing in the mechanical industry. It mainly bears radial loads and can also withstand a certain amount of axial loads.

3. Ball Bearing 6000 2rs

Ball bearings are essential components in mechanical equipment, and 6000 2RS ball bearings are one of the most commonly types. The characteristic of deep groove ball bearing is its two rubber seals, which can prevent contaminants from entering and also keep lubricant within the bearing.

4. Miniature Deep Groove Ball Bearing

Micro ball bearings refer to metric series with an outer diameter less than 9mm; The main materials include chrome steel, stainless steel, plastic, ceramics, etc. Among them, the minimum inner diameter can reach 0.6mm, and there are generally more ball bearings with an inner diameter of 1mm.

Material of Deep groove ball bearings

Chrome steel: Chrome steel has been used as the bearing material for many years due to its excellent properties and reliability. This kind of material can withstand high temperatures and heavy loads, so in the engineering industry, where efficiency, precision, and durability are crucial, chrome steel bearings are essential components.

Components of deep groove ball bearings

Inner ring

The inner ring is an internal component of deep groove ball bearings.The main function of the inner ring is to support the bearing and bear the load of the bearing during operation together with the outer ring.

Out rings

The outer ring is an external component of deep groove ball bearings.The main function of the outer ring is to support the bearing and bear the load of the bearing during operation.

Steel balls

Steel ball is the core component of deep groove ball bearings, usually they are made of high-strength steel. The main function of steel balls is to reduce friction and resistance within the bearings, thereby improving the operating efficiency of the bearing.

Cages

The cage is a fixed component of deep groove ball bearings.The main function of the cage is to separate the steel balls and maintain their relative position to ensure the stability and balance of the bearing during operation.

Process of deep groove ball bearings

Material selection

It is the first step in ensuring that a bearing will perform correctly and meet the operational requirements.

Cutting the steel pipe

The first step in producing ball bearings is cutting the steel pipe. Steel is an essential material for making ball bearings because it is strong and durable. The steel pipe is cut into small pieces known as blanks. These blanks will eventually become the spheres that are the most important part of a ball bearing.

Machining

It includes the processes of lathe and grinding. Lathes are used in the initial processing of the bearings by removing material from the object while grinding machines are used in the finishing process. We have the High precision machines to achieve tight tolerances and measurements which are required in producing quality bearings.

Heat treatment

After machining, the ring is heat-treated to improve its hardness, strength, and wear resistance. This is usually done through a process of quenching and tempering, which involves heating the ring to a high temperature and then rapidly cooling it.

Cleaning the rings

It is very important to clean the rings before assembling, as 1.Prolong the lifespan of the bearing.2.Prevent corrosion.3. Maintain the efficiency of the bearing 4. Reduce the risk of machine failure.

Assemble bearings

When the rings are ready, we assemble with steel balls and a cage to form the complete bearing unit. The balls are between the two rings, to create a smooth and friction-free rotation.

Lubrication

Finally, the bearing is lubricated with grease or oil to reduce friction and wear

Testing

After finished bearings, we will do various quality control tests to ensure bearings’ performance and durability. These tests can include measuring vibration, noise, rotation speed, load capacity and so on.

Marking items and brand

When the bearings are tested, we will mark items and brand on the rings, both customers' brand or our CTS brand are ok. We do the brands according to our customers' need.

FAQ

Q: What is the difference between a deep groove ball bearing and a tapered roller bearing?

A: The same with all roller bearings, tapered roller bearings have linear contact, while ball bearings have point contact. Line contact has a high load-bearing capacity, while ball bearings have a high speed capability.

Q: What are the advantages of deep groove ball bearings?

A: Deep groove ball bearings have a simplified design, low friction torque, and low operating temperature, and their expected lifespan is much longer than other types of bearings. After installation, they do not need any additional lubrication is required, which means less maintenance downtime.

Q: What does zz mean on a bearing?

A: Type ZZ - Non-removable, non-contact metal shield retained in the outer ring via crimping, or pressing. This type of shield cannot be removed once installed.

Q: Which bearing is better, RS or ZZ?

A: Generally,RS provides better sealing than 2Z, but with greater rolling friction. RS - bearing with rubber seal on one side, open on one side. 2 Z/ZZ - Bearings with metal seals on both sides. The Z-bearing has a metal seal on one side and an open side.

Q: What is the inner diameter of a 6000 bearing?

A: The 6000 ball bearing has an inner diameter of 10mm, an outer diameter of 26mm, and a width of 8mm. It is an open type ball bearing designed specifically for high speeds and high dynamic loads.
