Technical Specifications

Features and Benefits

Application-Specific Design

Unlike off-the-shelf products, each custom bearing is engineered for your exact load patterns, speeds, and environmental conditions. This translates directly into extended service life and lower total maintenance costs.

Flexible Configuration Options

Your equipment is unique—your Slewing Bearing Customize should be too. We adapt raceway geometry, gear specifications, and mounting interfaces to fit within your specific design constraints.

Material Optimization

We select materials and heat treatment processes specifically suited to your operating environment, whether that involves corrosive atmospheres, extreme temperatures, or high-shock conditions.

Reduced Get together Complexity

Custom mounting interfaces and integrated features can eliminate additional components, simplifying your assembly process and reducing overall system weight.

Performance Validation

Every custom bearing undergoes rigorous testing, including dimensional verification, hardness testing, and load testing, to ensure it meets your specified performance criteria.

Applications

Industrial Robots

Precision joints requiring compact designs with high moment capacity and precise positioning.

Medical Equipment

CT scanners, radiation therapy systems, and surgical robots demanding smooth, precise rotation and cleanroom-compatible operation.

Aerospace and Defense

Antenna positioning systems, turrets, and tracking equipment where absolute reliability is critical.

Precision Instruments

Telescopes, radar systems, and measurement equipment requiring minimal friction and high repeatability.

Custom Machinery

Special-purpose equipment, prototype development, and unique industrial applications that standard catalog products cannot fulfill.

Testing & Certification

Our comprehensive quality verification process includes:

· Dimensional Inspection: Coordinate measuring machines (CMM) verify all critical dimensions.

· Material Testing:Hardness testing and metallurgical analysis confirm specified material properties.

· Surface Quality:Roughness measurement and visual inspection ensure the required finish.

· Assembly Verification:Pre-delivery functional testing validates smooth and correct operation.

· Full Traceability:Complete documentation tracks every product from raw material to finished item.

Our manufacturing is certified to the ISO 9001 Quality Management System, ensuring consistent quality control. Our products also comply with RoHS environmental standards, meeting global regulatory requirements for restricted substances.

Installation Guide

Pre-Installation Checks:

1. Verify mounting surface flatness and cleanliness.

2. Confirm bolt hole alignment and thread condition.

3. Check bearing dimensions against the provided installation drawings.

4. Inspect all seal surfaces for any damage.

Installation Process:

1. Position the bearing onto the cleaned and prepared mounting surface.

2. Insert all bolts through the mounting holes, but do not tighten them initially.

3. Check alignment using dial indicators or other appropriate measuring tools.

4. Tighten the bolts in a star (cross) pattern to the specified torque value.

5. Verify smooth, free rotation of the bearing before applying the full operational load

Important Considerations:

1. Avoid impact forces during handling and transportation.

2. Use proper lifting equipment for large-diameter or heavy bearings.

3. Strictly follow the torque specifications provided for your custom design.

4. Always consult your custom design documentation for any specific requirements..

Maintenance and Care

Regular Inspection Schedule:

· Visual inspection for seal integrity: Monthly

· Bolt torque verification: Every 6 months

· Rotation smoothness check: Quarterly

· Lubrication assessment: Based on operating hours

Lubrication:

Re-lubrication intervals depend on your specific operating conditions and custom seal configuration. Consult your bearing documentation for detailed recommendations.

Warning Signs:

· Increased rotation resistance

· Unusual noise during operation

· Visible seal damage or lubricant leakage

· Excessive play or wobble

Service Life Extension Tips:

To maximize the lifespan of your bearing: protect it from contamination, maintain proper lubrication, and avoid shock loads that exceed its design specifications. Custom bearings engineered for your specific application typically offer a longer and more reliable service life compared to adapted standard bearings.

FAQ

Q: How long does a custom bearing development project take?

A: A typical timeline ranges from 2 to 4 weeks from final design approval to production completion, depending on the project's complexity and size. Expedited service is available upon request.

 Q: Do I need to provide 3D CAD files?

A: Not necessarily. We can work from 2D drawings, samples of existing bearings, or even reverse-engineer your current component through our technical drawing recreation services.

Q: What is the minimum order quantity (MOQ) for custom bearings?

A: We evaluate each project individually. Even single-piece prototypes are feasible for development and testing purposes.

Q: Can you manufacture bearings to match or replace those from other manufacturers?

A: Yes. Provide us with dimensions, photographs, or the physical bearing, and we'll produce a seamless replacement—often with design improvements based on our application analysis.

Q: What information do you need to start a custom project?

A: We require details such as load requirements, operating speeds, environmental conditions, space constraints, and mounting interface specifics. Our engineers will then guide you through the entire specification process.

Q: How do custom bearings compare in cost to standard catalog products?

A: The initial unit cost is higher. However, our custom solutions often reduce the total system cost through superior performance, longer service life, and the elimination of adaptation components or assemblies.
