Slim-Split Thin Ring Bearings
Dec 25,2025

1. What is the Slim-Split Thin Ring Bearing?

A Slim-Split Thin Ring Bearing is a compact, high-precision rolling bearing with an extremely thin cross-section, featuring open, split rings that allow for more and larger balls than standard bearings of similar size, enabling it to handle combined radial, axial, and moment loads efficiently in space-constrained applications like robotics, aerospace, and medical devices.

 3. Application of the Slim-Split Thin Ring Bearing

1. Robotics & Automation

Robot joints and rotary axes

Compact actuators

Automation modules

Slim-Split bearings reduce joint size and weight while allowing easy installation without full disassembly.

2. Medical Equipment

Imaging devices (CT, MRI auxiliary rotation parts)

Surgical and rehabilitation robots

Diagnostic equipment

Their compact size, smooth motion, and easy assembly suit space-restricted medical designs.

3. Aerospace & Defense

Aircraft control mechanisms

Satellite and space mechanisms

Radar and tracking systems

Weight reduction and maintenance-friendly split design are critical advantages.

4. Semiconductor & Electronics Manufacturing

Wafer handling systems

Inspection and positioning equipment

Precision rotary modules

Slim-Split bearings support high precision in compact assemblies.

5.Optical & Photonics Systems

Camera and lens assemblies

Optical alignment and focusing mechanisms

Beam steering platforms

They help maintain precise alignment with minimal space usage.

6. Industrial Machinery (Retrofit & Maintenance)

Equipment upgrades

Replacement in hard-to-dismantle assemblies

Compact gearboxes

The split design allows bearing replacement without removing shafts or housings, reducing downtime.

7. Precision Instruments

Measuring devices

Calibration equipment

Scientific instruments

Low friction and high repeatability support accurate measurements.

8. Defense & Surveillance Systems

Stabilized camera platforms

Target tracking units

Compact gimbals

Slim-Split bearings combine compactness, stiffness, and smooth rotation.

4. How to choose the Slim-Split Thin Ring Bearing?

Prioritize PA12 cage if: You need a cost-effective option, the working temperature is between -40°C to +120°C, and the environment is non-corrosive (e.g., general industrial automation, consumer electronics).

Choose stainless steel cage if: The application involves extreme temperatures (-60°C to +300°C), corrosive substances (acids, alkalis, solvents), heavy loads, or requires long service life (e.g., chemical processing, aerospace, food-grade equipment).

Consider customization needs: Select cage designs (crown-type, ribbon-type, machined windows), surface treatments (passivation, nickel plating, DLC coating), lubrication types, or sealing options based on specific working conditions.

5. The price of the Slim-Split Thin Ring Bearing

PA12 cage: Cost factor 1.0×, cost-effective and suitable for budget-sensitive projects.

Stainless steel cage: Premium option with a cost factor of 2.5–3.0×, offering higher performance and longer service life.
