Wholesale Adjustable Type Linear Ball Bearing

Adjustable Type Linear Ball Bearings for Precision Motion Systems

As a Wholesale Adjustable Type Linear Ball Bearing manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Shanghai Yinin Bearing & Transmission Company is a China-based manufacturer and supplier of adjustable type linear ball bearings, designed for applications where precise shaft alignment and controlled clearance are critical. Our range includes LM..UU-AJ, LMB...UU..AJ, and LME..UU..AJ series, each engineered to deliver smooth, low-friction linear motion in industrial automation, robotics, and mechanical equipment.

With over 20 years in the bearing industry and an annual production capacity of 8 million sets, we combine manufacturing expertise with responsive engineering support. We supply wholesale quantities to distributors and OEMs, offering consistent quality and customization to meet your specific motion requirements.

Product Range and Application Fit

Our adjustable linear ball bearings are available in three series, each tailored to different load, precision, and environmental demands. The table below summarizes their key characteristics and typical uses.

Engineering Value and Customization

We understand that every linear motion system has unique requirements. Our engineering team works with you to select the correct series, shaft diameter, and clearance setting. We can also customize dimensions, materials, and sealing options to suit your operating environment.

• Material: Chrome steel (GCr15) as standard, with stainless steel options for corrosive environments.
• Clearance adjustment: The adjustable feature allows you to fine-tune radial play to achieve the desired preload and stiffness.
• Precision: Bearings are manufactured to ISO tolerance classes, ensuring consistent shaft fit and smooth travel.

Quality Assurance and Testing

Quality is built into every stage of production. We conduct inspections after each manufacturing process, and finished bearings undergo full inspection according to customer requirements and international standards. Our testing includes dimensional accuracy, radial clearance, and noise/vibration checks.

We follow ISO 9001 quality management principles, and our factory is equipped with modern measuring instruments to verify critical parameters. This ensures that each batch meets the same high standards, whether you order 100 or 100,000 pieces.

Integration and Installation Support

Proper installation is key to maximizing bearing life. We provide technical documentation and guidance on housing design, shaft tolerances, and lubrication. Our team can also advise on preload adjustment procedures to achieve the optimal clearance for your application.

For automated systems, our bearings are compatible with standard linear shafts and housings. We can supply matched shafts and housings as part of a complete linear motion solution, simplifying your procurement and ensuring component compatibility.

Information We Use to Configure Your Solution

To prepare an accurate quotation and configuration, we need the following details from you:

• Shaft diameter and required travel length
• Load (radial and axial) and expected life
• Operating speed and duty cycle
• Environmental conditions (temperature, humidity, contamination)
• Required precision class and clearance adjustment range
• Quantity and packaging preferences

With this information, we can recommend the most suitable series and provide a detailed proposal, including drawings and technical specifications.

Frequently Asked Questions

What is the difference between adjustable and standard linear ball bearings?

Adjustable types have a split outer sleeve or a mechanism that allows you to reduce radial clearance after installation. This helps compensate for shaft wear or achieve a tighter fit for higher precision. Standard types have fixed clearance.

Can you provide stainless steel adjustable linear ball bearings?

Yes, we can manufacture adjustable linear ball bearings in stainless steel (e.g., 440C) for applications requiring corrosion resistance, such as food processing or medical equipment.

What is the typical lead time for wholesale orders?

For standard sizes in stock, we ship within 3 working days. For custom or non-standard orders, lead time depends on complexity and quantity, typically 2-4 weeks. We confirm exact delivery dates in our quotation.

How do I adjust the clearance on these bearings?

Adjustment is typically done by tightening a screw or nut on the bearing housing, which compresses the bearing's outer sleeve. Our technical datasheets provide step-by-step instructions, and our engineers can assist if needed.

Do you offer technical support for selecting the right bearing?

Absolutely. Our technical team can help you calculate load ratings, expected life, and recommend the appropriate series and size. We provide support throughout the project, from design to installation.
