📐 How should choose the right model for a Crossed Roller Bearings?

Selection of Crossed Roller Bearings

The core of selection is ensuring that the bearing's precision, rigidity, and load-bearing capacity meet the specific operating requirements of the equipment.

1. Structural Form: Selection is based on the installation requirements of the rotating parts: For outer ring rotation, use a split inner ring type; for inner ring rotation, use a split outer ring type; for both inner and outer rings rotating with high precision, use an integral structure (such as RU, CRBH type).

2. Size Range: The primary basis is the installation space of the equipment, determining the required inner diameter, outer diameter, and width.

3. Precision and Clearance: These are the core determinants of performance. Negative clearance improves rigidity and lifespan but increases friction; positive clearance is beneficial for high-speed operation but may reduce rigidity. A comprehensive selection must be made considering both speed and rigidity requirements.

4. Installation Method: Mainly divided into two categories: 1) Bearings with mounting holes on both inner and outer rings can be directly fixed with bolts; 2) Bearings without mounting holes require fixing via clamping flanges and bearing housings.

5. Load Capacity: Based on the radial force, axial force, and tilting moment that the equipment will bear, refer to the rated load table in the bearing catalog to select a model with sufficient load capacity and a certain margin.

6. Operating Environment: Consider the operating temperature, humidity, and cleanliness to select appropriate internal clearance, grease, and sealing type.

🛠️ What is the mounting procedure for RU124X bearings?

Key Points for Installing Crossed Roller Bearings

Due to their thin-walled structure, improper installation can easily cause deformation. The following procedure must be strictly followed.

Preparation Before Installation

Environmental Inspection: Conduct the inspection in a dry, clean environment.

Component Cleaning: Clean the bearing housing and mounting surfaces to remove dirt and burrs.

Structural Rigidity Confirmation: The rigidity of the mounting section is crucial; insufficient rigidity will significantly reduce bearing performance.

Installation Process

Gently Press In: Apply even pressure to the end face of the raceway and gently tap it circumferentially with a plastic hammer. Slowly and horizontally install the bearing; direct tapping is strictly prohibited.

Flange Installation: After placing the flange, slightly wiggle it to adjust the bolt position. Tighten the bolts by hand to confirm accurate thread alignment.

Bolt Tightening: Tighten in 3 to 4 stages, repeatedly tightening diagonally to the specified torque. During tightening, the integral raceway can be slightly rotated to correct the joint of the split races.

Post-installation inspection

Rotation test: After manually confirming smooth rotation, conduct a no-load, low-speed test run, gradually increasing the speed and load while monitoring noise, vibration, and temperature rise. Stop immediately if any abnormality is detected.

📋 Special Note for mounting RU124X bearings?

Special Notes

Seam Treatment of Split Rings: Before installation, if any misalignment is found in the seam of the inner or outer ring, loosen the fixing bolts, gently tap it with a plastic hammer to correct the misalignment, and then install. Do not force assembly.

Precautions for Fixing Bolts: During installation or disassembly, never apply additional external force (such as hammering) to the connecting bolts to avoid damaging the threads or bolts.

Grease Management: The bearings come with grease at the factory and can be used directly. Afterward, high-quality grease should be added every 3 to 6 months. Initially, resistance will be higher after adding grease; after operation, excess grease will overflow, and the torque will return to normal.

Operating Temperature Limits: The standard operating temperature range for crossed roller bearings is -20 to 120°C. However, for types with spacers or seals, the maximum allowable temperature and continuous operating temperature will be lower, requiring special attention.

Positioning Holes and Plugs: For bearings with mounting holes, the roller insertion holes usually have plugs. During installation, ensure that the plugs are positioned away from the area of ​​maximum load to prevent stress concentration.

If you can provide more specific application scenarios (such as robot joints, machine tool turntables) or load parameters, I can do a more in-depth selection analysis for you.
