Design and Engineering
Construction of THK Cross Roller Rings
THK Cross Roller Rings are designed with cylindrical rollers arranged in a 90° V groove, with each roller perpendicular to the adjacent roller, separated from each other by a spacer retainer. This unique design allows a single bearing to receive loads in all directions, including radial, axial, and moment loads. The compact and thin design of the Cross Roller Ring makes it an ideal solution for applications where space is limited.
Material Specifications
THK uses high-quality materials in the construction of Cross Roller Rings to ensure durability and longevity. The rollers are made of high-carbon chromium bearing steel, while the inner and outer rings are made of high-carbon chromium bearing steel or stainless steel. The spacer retainer is made of a synthetic resin material that provides excellent wear resistance and low friction.
Precision and Accuracy
THK Cross Roller Rings are known for their high precision and accuracy. The rollers are ground to a high degree of accuracy, and the V-shaped groove in which they are placed is also ground to a high degree of precision. This ensures that the rollers are guided smoothly and accurately, resulting in a bearing that can handle high loads with minimal friction and wear. THK Cross Roller Rings are also designed to be highly rigid, which further enhances their precision and accuracy.
In summary, the construction of THK Cross Roller Rings, the use of high-quality materials, and the focus on precision and accuracy make them an excellent choice for applications where space is limited, and high loads and precision are required.

Installation and Maintenance
Installation Procedures
When installing the THK Cross Roller Ring, it is important to follow proper procedures to ensure proper function and longevity of the product. The following steps should be taken:
- Thoroughly clean the housing and other assembly parts, and make sure there are no burrs.
- When inserting the cross roller ring into the housing or onto the shaft, use a plastic hammer or similar tool to level the cross roller ring by gradually hammering the perimeter while inserting. Since the cross roller ring has a thin-walled structure, it is easily tilted during insertion.
- For a type secured with rivets, install it as-is.
- When using clearance adjustment bolts, closely contact rails 2 and 3 onto the base.
Lubrication and Care
Proper lubrication is important for the smooth operation of the THK Cross Roller Ring. The following guidelines should be followed:
- Use a high-quality lubricant that is compatible with the materials used in the cross roller ring.
- Lubricate the cross roller ring regularly according to the manufacturer’s recommendations.
- Avoid using too much lubricant, as this can cause the cross roller ring to become contaminated with debris and dirt.
Troubleshooting and Replacement
If you experience any issues with your THK Cross Roller Ring, the following steps should be taken:
- Check the lubrication level and quality. If necessary, add more lubricant or replace the existing lubricant.
- Inspect the cross roller ring for signs of wear or damage. If the cross roller ring is damaged, it may need to be replaced.
- If the cross roller ring needs to be replaced, follow the manufacturer’s instructions for proper installation.
By following these guidelines, you can ensure proper installation, maintenance, and care of your THK Cross Roller Ring, which will help to extend its lifespan and ensure reliable operation.
