Robot Arm Used Cross Roller Bearing Ru228ru228xuucc00 P2p4p5 Rolling Bearing in Stock

RB series crossed roller bearing
RB series (outer ring division type with inner rotating), this type is the basic type of crossed roller bearings. The outer rings have two parts, and the inner ring is one integer. The type is well applied to the situation which need high rotation accuracy on inner ring. For example, it is suitable for the rotary part of the indexing table of the tools machine.

CROSS ROLLER BEARINGS

Crossed roller bearings

If you are looking for high-precision, high-load capacity bearings, you might consider cross roller bearings. In this article, we will discuss everything you need to know about cross roller bearings, including their construction, principle of operation, applications, and advantages.

What are cross roller bearings?

Crossed roller bearings, also known as cross roller bearings, are a type of roller bearing with cylindrical rollers arranged in a cross between two inner and outer rings. This configuration allows for high stiffness, precision and axial load capacity.

Structure of cross roller bearings

Crossed roller bearings consist of two sets of rollers that cross each other at right angles. The rollers are held in place by a synthetic resin or brass cage. The inner and outer rings are made of steel or stainless steel and have raceways for the rollers.

Principle of operation of cross roller bearings

Crossed roller bearings operate on the principle of linear contact between the rollers and raceways. The rollers roll between the raceways, transmitting loads in all directions, including axial, radial and moment loads. The linear contact between the rollers and raceways ensures high rigidity and precision.

Advantages of cross roller bearings

Cross-roller bearings have many advantages over other types of bearings. Some of these advantages are.

• High load capacity: Crossed roller bearings can handle both axial and radial loads, making them ideal for applications requiring high load capacity.

• High stiffness: The cross configuration of the rollers ensures high stiffness and precision, making them suitable for applications requiring precise positioning.

• Compact design: The cross-roller bearings have a compact design that allows them to be used in tight spaces.

• Low friction: The linear contact between the rollers and raceways results in low friction and reduced heat generation.

Applications of cross roller bearings

Crossed roller bearings are used in a wide range of applications, including:

• Robotics: Cross roller bearings are commonly used in robotics for precision movements and positioning.

• Medical equipment: Cross roller bearings are used in medical equipment such as CT scanners, X-ray machines and surgical robots.

• Machine tools: Cross roller bearings are used in machine tools such as milling machines, lathes and grinders for high-precision cutting and grinding.

• Industrial automation: Cross-roller bearings are used in industrial automation equipment, such as pick-and-place robots and assembly machines.

Selection of cross roller bearings

When selecting cross-roller bearings, several factors need to be considered, including load capacity, stiffness, accuracy and speed. Other factors to consider are size, weight and mounting requirements.

Maintenance of cross roller bearings

Proper maintenance of cross roller bearings is essential for their long-term performance. Maintenance operations include lubrication, cleaning, and inspection for wear and damage.

Conclusion

Cross-roller bearings are a versatile and reliable type of bearing that can handle high loads and provide high stiffness and precision. They are used in a wide range of applications, from robotics to medical equipment and industrial automation. When selecting cross roller bearings, it is essential to consider factors such as load capacity, stiffness, precision and maintenance requirements.
