Cross Cylindrical Roller Slewing Bearing - Image 4

The crossed cylindrical roller slewing bearing is a specially structured slewing bearing. Its core design features cylindrical rollers arranged crosswise at a 90° angle to each other within the raceway.The rollers are 1:1 cross arranged.

Therefore, it is widely used in equipment with strict requirements for precision and space, such as industrial robots, high-precision machine tools, medical equipment, and radar pan-tilt systems.

Overview of Customized Cross Cylindrical Roller Slewing Bearings VKUKEN Cross Cylindrical Roller Slewing Bearing composed of inner ring, outer ring, rolling element and isolation block. The rollers are 1:1 cross arranged. It can bear the axial force, the overturning moment and a relatively large radial force simultaneously. Cylindrical rollers are arranged crosswise at 90° perpendicular to each other in the raceway. Spacers or separators are installed between the rollers to prevent tilting, mutual friction, increased rotational torque, and avoid contact or jamming. Features of Customized Cross Cylindrical Roller Slewing Bearings • Strong load-carrying capacity: Can simultaneously bear large radial loads, axial loads, moment loads, and loads in all directions. • High rotational accuracy: Through precision machining, assembly technology, and adjustable clearance design, it can achieve extremely high rotational accuracy with small runout during rotation. • Good rigidity: The cross-arranged rollers have a large contact area with the raceway, effectively resisting deformation and ensuring the bearing remains stable under high loads. • Easy installation: The outer or inner ring, which is split into two parts, is fixed together after the rollers and retainers are installed, making the installation operation simple. • Space-saving: The inner and outer rings are miniaturized to the minimum size, with an ultra-thin structure close to the limit of small size, suitable for equipment with limited space. Applications of Customized Size Cross Cylindrical Roller Slewing Bearing VKUKEN bearings are widely used in steel, port crane, engineering machinery, radar, shield machine, Wind power generation equipment, crane, radio telescope and other fields. Price of Customized Cross Cylindrical Roller Slewing Bearings Since most Cross Cylindrical Roller Slewing Bearings are custom-made, there is no fixed price. Quotes are provided based on the specific project requirements, ranging from tens of dollars to tens of thousands of dollars. We consistently prioritize quality while offering affordable prices to serve our clients.

Qualifications a Reputable Slew Bearings Supplier Should Possess

Globally, there are few factories capable of manufacturing slew bearings due to the significant investment required, including expensive machining equipment and overhead cranes. The ability to organize transportation is also crucial. We are a state-owned and majority-controlled slew bearing manufacturer with world-class production and lifting equipment, and a highly skilled engineering team. We can provide you with comprehensive technical services including on-site surveying, design, bearing selection, and installation support for slew bearings.

1. High Load Capacity in All Directions

Cylindrical rollers are arranged orthogonally (90° cross arrangement) between inner and outer rings.
Capable of simultaneously supporting axial loads, radial loads, and overturning moments.
One bearing can replace multiple bearing sets, simplifying system design.

2. Excellent Rotational Accuracy and Rigidity

Line contact between rollers and raceways ensures high stiffness and minimal elastic deformation.
Suitable for applications with precise positioning, smooth rotation, and low runout requirements.

3. Compact and Space-Saving Design

Compared with traditional slewing bearing combinations, cross cylindrical roller designs are thinner and lighter.
Ideal for compact equipment where installation space and weight are critical constraints.

4. Stable Performance Under Heavy and Dynamic Loads

Even load distribution across multiple rollers reduces localized stress.
Maintains stable performance under frequent start-stop, reversing rotation, and shock loads.

5. Flexible Structural Options

Available with internal gear, external gear, or without gear configurations.
Can be customized for mounting holes, sealing structures, preload levels, and materials to match specific applications.

6. Long Service Life and Low Maintenance

Optimized raceway geometry and surface treatment improve wear resistance and fatigue life.
Proper lubrication enables long-term operation with reduced maintenance frequency.

1. Industrial Robots and Automation Equipment

Robot joints, rotary tables, indexing mechanisms
Ensures high positioning accuracy, rigidity, and repeatability

2. Precision Machine Tools

Rotary tables, machining centers, turntables
Supports high-precision rotation under combined cutting forces

3. Construction and Lifting Machinery

Small and medium cranes, aerial work platforms
Handles high overturning moments with compact bearing size

4. Medical and Imaging Equipment

CT scanners, medical rotating platforms
Provides smooth, quiet rotation with high reliability

5. Semiconductor and Precision Manufacturing Equipment

Wafer handling systems, inspection platforms
Meets requirements for high cleanliness, accuracy, and stability

6. Military, Aerospace, and Optical Equipment

Radar systems, tracking platforms, antenna drives
Suitable for high-load, high-precision, and harsh operating conditions

We can customize non-standard bearings according to customer drawings, or we can measure and create drawings of existing bearings on-site and then manufacture custom bearings based on those drawings. Our team of professional engineers has over 20 years of experience in bearing design and measurement.

Bearing knowledge training

We have found that many people would like to learn about the application technology and selection of Bearing but do not have suitable materials to read. Our team of engineers constantly exports technology on our download page and blog, which you can download for free.

application engineer

Hi, I am Maxwell, I am an engineer in the field of bearing applications. I majored in mechanical and electromechanical engineering during college. After graduation, I worked for the top three "SKF" bearing companies in the world for ten years , during which I went to dozens of customers in different industries to help them solve problems in bearing applications; later I joined VKUKEN Bearing Manufacturing, and I will share bearing technical knowledge on this website from time to time. If you are a customer Please contact me to help you solve your problem; if you are also a technical expert in bearings, I am very willing to exchange technical knowledge about bearings with you.
