Cross roller bearing
In crossed cylindrical roller bearings, the cylindrical rollers are arranged in two 90° V-shaped raceways at a 90°included angle 1:1, and the cylindrical rollers are separated by the spacer block. This structure makes a set of bearings It can bear radial load, axial load and overtuming load at the same time.
     This kind of combined bearing has a compact structure, and at the same time greatly simplifies the structure design of the bearing under the premise of ensuring structural rigidity. Most bearings can be pre-loaded before leaving the factory, which further facilitates installation and maintenance work. Therefore, cross cylindrical roller bearings. It has the characteristics of high precision,high load and high rigidity,which is very suitable for the occasions where the space size is clearly restricted,such as the rotating  part  of  the  robot,the  joint  part  of  the  manipulator,the numerical  control  inHangZhou  table,the  medical  equipment,and  the measuring  instrument.
Â
Rotary table bearing
In the rotary table bearing, the radial raceway of a thrust/centripetal   Lshaped inner ring, the radial raceway of a thrust/centripetal seat ring  and  a set of radial cylindrical rollers form the radial part of the rotary  table bearing. The axial raceway of the thrust/centripetal Lshaped Â
inner ring, the two axial raceways of the thrust/centripetal seat ring,Â
and two sets of thrust cylindrical rollers and their retainers form the axial part of the rotary table bearing. The radial and axial combined structure of this series enable it to withstand radial load, bidirectionalÂ
axial load and overturning moment. This series of bearings can beÂ
preloaded and can achieve high rotation accuracy, so it is particularly
suitable for CNC rotation workbenches, swing-angle milling heads,Â
gear grinding machine workbenches and other workplaces thatÂ
require high precision.
The inner ring and outer ring of this series of bearings are designed with   screw mounting holes, which makes the installation and fixing
very simple; at the same time, the bearing preload is adjusted according to the working conditions at the factory, so there is no need to adjust the installation preload during installation.
The inner ring and outer ring of the bearing are designed with lubricating oil holes, through which lubricating grease can be conveniently added and replenishing the inside of the bearing.
Â
Harmonic reducer bearings
Harmonic reducer is mainly composed of harmonic generator, flexible wheel, rigid wheel 3 basic components, in addition to rigid bearing (cross roller bearing) and flexible bearing (thin wall deep groove ball bearing).
The inner hole of the flexible bearing is matched with the elliptical cam outer ring. The outer ring is elastically deformed by the ball to match the inner diameter of the opening of the flexspline.The gear on the outer periphery of the opening of the flexspline meshes with  the teeth of the rigid gear.The number of teeth of the rigid wheel is more than that of the flexible wheel.The flexible wheel and the rigid wheel are meshed on the long axis and separated on the short axis.The bottom of the flexible wheel is fixed at the output end, and the rigid bearing is installed at the output end of the reducer to connect with the outside. Harmonic reducer is usually used in robotics,machine tools,aerospace and other industries.Accuracy, rigidity and bearing capacity and other requirements are very high. So the processing accuracy and installation accuracy of each part of the harmonic reducer are very high,the same requirements for bearings are also very high. The most important things for a rigid bearing are its rigidity, reliability and precision of rotation. Before the rigid bearing delivering to customer, the bearing will be adjusted to a certain preload to ensure that the bearing is sufficiently rigid;The most important thing maximum radial deformation of the bearing.

Are there specific maintenance practices that can extend the life of cross roller bearings?
Implementing proper maintenance practices is essential for extending the life of cross roller bearings. Regular maintenance helps prevent premature wear, minimize downtime, and ensure optimal performance. Here are specific maintenance practices that can contribute to extending the life of cross roller bearings:
- Regular Inspection:
- Lubrication:
- Contamination Control:
- Proper Mounting:
- Load and Speed Considerations:
- Periodic Reassessment:
- Training and Documentation:
Perform regular inspections of cross roller bearings to detect any signs of wear, damage, or abnormal operating conditions. Visual inspections can identify visible damage, such as cracks, pitting, or corrosion. Additionally, monitoring noise, vibration, and temperature levels during operation can help identify potential issues early on.
Proper lubrication is crucial for the smooth operation and longevity of cross roller bearings. Follow the manufacturer’s recommendations regarding the type and quantity of lubricant to use. Establish a regular lubrication schedule and ensure that the bearings are adequately lubricated. Monitor the lubricant condition and replenish or replace it as needed to maintain optimal lubrication levels.
Preventing contamination is essential for the longevity of cross roller bearings. Implement measures to control and minimize the ingress of contaminants, such as dust, dirt, or moisture. Use appropriate sealing or shielding mechanisms to protect the bearing from external particles. Clean the surrounding area regularly and ensure that the bearing housing and mounting surfaces are free from debris.
Ensure proper mounting and alignment of cross roller bearings to avoid unnecessary stress or misalignment that can lead to premature wear. Follow the manufacturer’s guidelines for mounting procedures, including the use of suitable tools and torque values. Ensure that the mounting surfaces are clean, flat, and perpendicular to minimize stress concentrations.
Be mindful of the recommended load and speed limits specified by the bearing manufacturer. Avoid exceeding these limits as it can accelerate wear and decrease the bearing’s lifespan. If operating conditions change, such as increased load or speed, consult the manufacturer for guidance on appropriate bearing selection or additional maintenance measures.
Periodically reassess the operating conditions and performance of cross roller bearings. As equipment and usage patterns may change over time, it is essential to periodically review the bearing’s performance and consider reevaluating maintenance practices. This can help identify potential improvements or adjustments to ensure continued reliability and longevity.
Provide training to personnel responsible for the maintenance and operation of equipment that utilizes cross roller bearings. Ensure they are familiar with proper maintenance procedures and understand the importance of adhering to maintenance schedules. Maintain documentation of maintenance activities, including inspection reports, lubrication records, and any interventions or replacements performed.
By implementing these specific maintenance practices, it is possible to extend the life of cross roller bearings, optimize their performance, and minimize the risk of premature failures. Regular inspections, proper lubrication, contamination control, proper mounting, considering load and speed limits, periodic reassessment, and training and documentation are all key aspects of effective maintenance for cross roller bearings.
