Crossed roller bearings are integral to applications requiring high precision and load capacity, such as robotics, machine tools, and medical equipment. Proper installation of these bearings is crucial to ensure optimal performance, longevity, and safety. This step-by-step guide will walk you through the process of mounting crossed roller bearings, as well as things to keep in mind.

Understanding Crossed Roller Bearings

Crossed roller bearings are characterized by their unique structure, where cylindrical rollers are arranged alternately at 90 degrees to one another. This configuration allows the bearing to simultaneously handle radial, axial, and moment loads, making it highly efficient in compact spaces.

Buyers looking for precision and durability often consider LKPB as a reliable alternative to brands like Schaeffler, THK, and IKO. LKPB offers customizable solutions, including non-standard sizes and OEM acceptance, tailored to meet specific industry requirements.

Preparing for Mounting

Before starting the mounting process, ensure that all tools and materials are prepared:

Crossed Roller Bearing (LKPB or similar)
Mounting surface
Lubricant
Precision tools (torque wrench, dial gauge, etc.)
Mounting screws or bolts

The environment should be clean and free from dust, as even the smallest contamination can affect bearing performance. Buyers often opt for high-quality products from manufacturers like LKPB, where meticulous attention to material quality and production standards helps ensure long-lasting performance in challenging environments.

Step-by-Step Mounting Process

To avoid violent installation or impact, must ensure that gently loaded into the bearing, bearing and seat hole for the tiny clearance fit, normal conditions should be gently tapping the bearing surface in the right place to load, hard impact leads to tilt of the mounting surface is not easy to load, may be damaged or even scrapped the bearing seat.
Bearing inner sleeve must be installed with induction heating, and shall not exceed 120 ℃. It is strictly prohibited to dismantle the bearings by open flame heating.
If the bearings can not be loaded, find out the reasons, eliminate the problem and take reasonable measures, found that there are parts deformation and other problems should be repaired in a timely manner, if necessary, need to modify the drawings.
But also strictly in accordance with the requirements of the injection of a sufficient amount of clean grease.
Found in the installation of unqualified seals or other parts, must be strictly scrapped or repaired to ensure that the assembly quality in line with the bearing performance requirements.

Post-Installation Tips

Crossed roller bearings should be checked after installation to ensure that the bearing installation is completed, to ensure that the installation is correct.
In addition to the installation should pay attention to see the lubrication effect, although in the installation before the use of grease, but if the amount of grease is small, or the installation process of grease falling off the situation can not be avoided, so add grease in a timely manner.
In addition to pay attention to the bearings in the necessary circumstances, you can carry out test runs to see whether the bearing operation of the bearings in line with the use of demand, and at the same time to see whether the bearings can be used normally.

Crossed Roller Bearing Mounting Points Summary

1. Prevent impact mounting: In the mounting process, it is strictly prohibited to use heavy hammers and other tools that may generate impact, so as not to cause irreversible damage to the raceways and rollers of the bearings.

2. Precisely regulate the preload: the adjustment of the preload needs to be precisely in place, whether it is too large or too small preload, will have a negative impact on the performance and durability of the bearings.

3. Follow the manufacturer’s instructions: Be sure to follow the thorough installation guidelines and recommended practices provided by the bearing manufacturer, which are key to ensuring that the bearings are installed correctly.

4. Perform regular maintenance checks: After installation, a regular inspection and maintenance system should be established, including grease replacement, cleaning of seals and dust shields, etc., to maintain the optimal working condition of the bearings and ensure their long-term stable operation.

5. As shown in the figure below, the locking of the fixing bolts can be divided into 3 stages from incomplete locking to full locking, and the tightening is repeated in the order on the diagonal. The deviation of the inner and outer rings from the main body can be corrected by turning the overall outer or inner ring slightly while tightening the inner or outer ring.
