What is the CRBH-type crossed roller bearing？

The CRBH-type crossed roller bearing is a high-rigidity precision rolling bearing. Its rollers are embedded in the V-shaped raceway of the cross roller ring at a 90° orthogonal angle, with a split outer ring structure. It can bear radial loads, axial loads and overturning moments simultaneously, and is a core component of heavy-duty precision transmission systems.

NEWBEE Transmission's CRBH cross roller bearing, relying on the "roller-raceway" full-contact design, has a 40% higher load-carrying capacity than traditional bearings under the same volume, while maintaining high-precision rotation performance. It is widely used in heavy-duty equipment with strict requirements on rigidity and stability.

Features of the CRBH-type crossed roller bearing

<!--[if !supportLists]-->1. <!--[endif]-->Super strong load-carrying capacity: The orthogonal roller layout of the CRBH cross roller bearing and the widened raceway design of the cross roller ring can bear radial, axial and moment loads simultaneously. A single bearing can replace the combination of multiple bearings, greatly simplifying the equipment structure. By optimizing the roller diameter and arrangement density, NEWBEE Transmission has increased the rated dynamic load of the CRBH cross roller bearing by 30%.

<!--[if !supportLists]-->2. <!--[endif]--> Excellent rigidity performance: The line contact design between the rollers and the raceway reduces contact stress. The CRBH cross roller bearing undergoes integral quenching treatment (base material hardness HRC 58-60), and its anti-deformation ability is 25% higher than that of ordinary crossed roller bearings. The rigidity advantage of the cross roller ring is particularly prominent under heavy-load working conditions.

<!--[if !supportLists]-->3. <!--[endif]-->Precise rotation performance: The rotation accuracy of the CRBH cross roller bearing reaches P5/P4 grade, with radial runout ≤ 0.003mm and end face runout ≤ 0.005mm, suitable for high-precision positioning scenarios. NEWBEE Transmission's precision grinding process ensures that the raceway tolerance of the cross roller ring is controlled at the micrometer level, guaranteeing stable operation.

<!--[if !supportLists]-->4. <!--[endif]-->Flexible and convenient installation: The split outer ring design allows the CRBH cross roller bearing to fine-tune the preload during installation, reducing cumulative assembly errors; the integrated cage structure of the cross roller ring avoids roller deviation, further improving the operational stability of the system.

<!--[if !supportLists]-->5. <!--[endif]--> Long service life and environmental resistance: Using 440C stainless steel or SUJ2 high-carbon chromium steel as the base material, the CRBH cross roller bearing can adapt to humid environments after anti-rust treatment; NEWBEE Transmission's special lubrication technology extends the bearing life to 1.5 times that of traditional products.

Applications of the CRBH-type crossed roller bearing

With the advantages of high rigidity and composite load-carrying capacity, the CRBH cross roller bearing is widely used in the following fields:

Industrial robots: Rotating joints of heavy-duty robotic arms, waist rotating units of palletizing robots. The high load-carrying capacity of the CRBH cross roller bearing ensures the precise operation of the arm under heavy loads.

Precision machine tools: CNC turntables, rotating axes of boring and milling machines. The rigid support of the cross roller ring meets the stability requirements of heavy-duty cutting.

Heavy-duty equipment: Positioners of automated welding robots, rotating platforms of large warehouse machinery. The CRBH cross roller bearing can bear instantaneous impact loads without affecting accuracy.

New energy equipment: Yaw bearings of wind power equipment, heavy-load handling robotic arms for photovoltaic modules. NEWBEE Transmission's CRBH cross roller bearing is suitable for complex outdoor environments.

Aerospace: Rotating frames of ground simulation equipment, heavy-load steering mechanisms of satellite antennas. The low-vibration characteristic of the CRBH cross roller bearing ensures the measurement accuracy of precision instruments. Factors affecting the price of the CRBH-type crossed roller bearing

The price of the CRBH cross roller bearing is affected by the following factors:

<!--[if !supportLists]-->1. <!--[endif]-->Material selection: The price of the CRBH cross roller bearing made of 440C stainless steel (corrosion-resistant) is 25%-35% higher than that of SUJ2 steel, which is suitable for humid or outdoor environments.

<!--[if !supportLists]-->2. <!--[endif]-->Precision grade: Due to the high requirement for grinding precision, the price of P4 grade CRBH cross roller bearing is 20%-30% higher than that of P5 grade, which is suitable for ultra-high precision positioning scenarios.

<!--[if !supportLists]-->3. <!--[endif]-->Specification and size: The price of CRBH cross roller bearings with an inner diameter of 100-200mm is relatively low. For products with an inner diameter > 300mm or an ultra-large outer diameter (> 500mm), the price increases stepwise with the increase of processing difficulty.

<!--[if !supportLists]-->4. <!--[endif]-->Customization requirements: The price of CRBH cross roller bearings with sealing rings (IP65 protection), high-temperature grease (-30℃~120℃) or surface coating increases by 15%-25%. For specific quotations, you can contact NEWBEE Transmission for the latest solutions.

What factors need to be considered when purchasing the CRBH-type crossed roller bearing ?

<!--[if !supportLists]-->1. <!--[endif]-->Size matching: The inner diameter range of the CRBH cross roller bearing is 80mm-500mm. It is necessary to accurately measure the inner diameter (d), outer diameter (D) and width (B). NEWBEE Transmission provides a full range of standard models and non-standard customization to adapt to different heavy-duty equipment.

<!--[if !supportLists]-->2. <!--[endif]-->Precision requirements: For ultra-high precision scenarios (such as CNC turntables), P4 grade CRBH cross roller bearing is selected; for general heavy-load scenarios, P5 grade is sufficient.

<!--[if !supportLists]-->3. <!--[endif]-->Environmental adaptation: For humid or corrosive environments, priority should be given to 440C stainless steel CRBH cross roller bearing; for high-temperature scenarios, cross roller rings with customized high-temperature tempering treatment are required.

<!--[if !supportLists]-->4. <!--[endif]-->Supplier qualifications: Choose suppliers like NEWBEE Transmission that can provide material inspection reports and load test data to ensure the reliability and consistency of the CRBH cross roller bearing.

<!--[if !supportLists]-->5. <!--[endif]-->Price rationality: Compare quotations from different suppliers. NEWBEE Transmission's large-scale production mode can reduce the unit cost of the CRBH cross roller bearing while providing long-term technical support.

Precautions for using the CRBH-type crossed roller bearing

<!--[if !supportLists]-->1. <!--[endif]-->When installing the CRBH cross roller bearing, it is necessary to adjust the preload evenly through the bolts of the split outer ring. Avoid hitting the cross roller ring to prevent raceway damage. It is recommended to use a torque wrench to control the installation force.

<!--[if !supportLists]-->2. <!--[endif]--> Inject special grease before operation (the filling amount is 1/2-2/3 of the internal space). For heavy-load scenarios, extreme pressure lithium-based grease is recommended; for high-temperature environments, polyurea grease is recommended.

<!--[if !supportLists]-->3. <!--[endif]-->Regularly check the temperature (normal ≤ 80℃) and noise value of the CRBH cross roller bearing. If abnormal vibration is found, stop the machine for inspection in time to avoid deformation of the cross roller ring due to overload.
