Guide to Crossed Roller Bearing Dimensions

As a high-performance mechanical component, crossed roller bearings play a vital role in modern industry due to their unique structural design and excellent performance. Their applications cover a wide range of fields from high-precision machine tools to aerospace equipment. This article will delve into the advantages, types, dimension tables, applications, selection methods, as well as conclusions and FAQs of crossed roller bearings to help you fully understand this key component.

Crossed roller bearings have many advantages in high-precision and high-load applications, mainly including the following aspects:

High Precision

Crossed roller bearings are manufactured with extremely high precision, and the clearance between their rolling elements is strictly controlled, ensuring that the bearings have high rotational accuracy during operation. This high-precision feature makes crossed roller bearings particularly good in applications that require high-precision positioning and rotational motion, such as CNC machine tools and optical instruments.

Good High-Speed Performance

Due to the optimization of the structural design, crossed roller bearings can also maintain good performance when running at high speeds. Its rolling elements have low friction and low temperature rise during operation, and can work stably in high-speed rotating equipment, such as centrifuges and turbomachinery.

High Rigidity

The rolling elements of crossed roller bearings are arranged linearly, and this design makes the bearings very rigid. It can remain stable under high loads and prevent deformation, thereby ensuring high precision and stability of the equipment.

Strong Load Capacity

Cross roller bearings can simultaneously withstand multi-directional loads such as radial, axial and overturning moments. This versatile load capacity enables it to maintain good performance under complex load conditions.

Compact design Crossed roller bearings have a compact design that provides the same or even higher performance in a smaller space than conventional bearings. This makes them particularly suitable for applications that require space and weight savings, such as robotic joints and aerospace equipment.

Types and size tables of crossed roller bearings

Depending on their structure and rolling elements, crossed roller bearings are mainly divided into crossed cylindrical roller bearings and crossed tapered roller bearings. The following is a detailed introduction to these two types:

Cross cylindrical roller bearing size chart

The rolling elements of cross cylindrical roller bearings are cylindrical rollers arranged in a 90° cross state, which can simultaneously withstand radial, axial and overturning moments. According to the specific design and use, cross cylindrical roller bearings can be further divided into the following types:

RB type size chart

RB type cross roller bearings are basic types, with an outer ring divided into two pieces and an inner ring of an integral structure, suitable for occasions requiring high inner ring rotation accuracy. This bearing has a compact structure and can provide high rigidity and high precision.

Crossed tapered roller bearings

Crossed tapered roller bearings consist of two rows of rollers that are perpendicular to each other and are arranged alternately in the raceway. The tilt angle and tapered geometry of the bearings enable them to withstand high axial and radial loads and provide high rigidity and precision. Crossed tapered roller bearings are often used in applications that require precise positioning and high load capacity, such as high-precision machine tools and large mechanical equipment.

Application of Crossed Roller Bearings

Crossed roller bearings are widely used in various mechanical equipment that require high precision, high rigidity and high load capacity. Here are some of the main application areas:

Factors for selecting crossed roller bearings

Choosing the right crossed roller bearing model is crucial to the performance and life of mechanical equipment. Here are a few key factors to consider when selecting:

Bearing type

Choose the appropriate bearing type based on the specific application and load requirements of the equipment. Crossed cylindrical roller bearings are suitable for applications with large radial and axial loads, while crossed tapered roller bearings are suitable for applications that require high rigidity and high-precision positioning.

Bearing size

Before selecting, it is necessary to determine the bearing size based on the shaft size of the equipment and the reserved installation space. Ensure that the installation selection of the bearing meets the design requirements of the equipment and minimizes the installation space.

Bearing structure

Different crossed roller bearings have different structural designs, such as outer ring split type, inner ring split type and integral structure. Select the appropriate structure according to the specific installation requirements and rotating parts of the equipment.

Bearing load capacity

Understand the load capacity required by the equipment and select a crossed roller bearing with corresponding load capacity according to the load requirements of the equipment. Ensure that the bearing can withstand the load applied by the equipment during use.

Installation and maintenance

Consider the ease of installation and maintenance of the bearing. Choosing a bearing model that is easy to install and maintain can reduce the maintenance cost of the equipment and improve operating efficiency.

Conclusion

Cross roller bearings have a wide range of applications in modern industry due to their high precision, high rigidity and high load capacity. Through reasonable selection and proper maintenance, cross roller bearings can significantly improve the performance and life of equipment and meet the application requirements of high precision, high load and high stability.
