Nova Bearing: Medical Grade Bearings for Healthcare Equipment 

Miniature Precision Bearings for Medical & Rehabilitation Equipment

At Nova Bearing, we specialize in manufacturing high-precision miniature and small deep groove ball bearings with inner diameters ranging from 1mm to 15mm. Our core product line includes the 60, 62, 63, 68, and 69 series, engineered to meet the strict demands of critical medical and rehabilitation equipment. From life-saving ventilators to daily-use mobility aids, our bearings ensure smooth, quiet, and reliable performance for every patient and care provider. 

1. Medical Transport Stretcher & Patient Beds

Hospital stretchers and patient beds require robust, low-friction components for smooth and safe movement. Our 1mm-15mm miniature bearings are used in the wheel casters, lifting mechanisms, and adjustment hinges.

- Application: Our 60 and 62 series bearings (5mm-10mm bore) ensure the wheels roll quietly and the bed height/angle adjusts smoothly.

- Benefit: Durable construction supports heavy loads while maintaining precision for years of reliable use in busy hospital environments. 

2. Dental Treatment Units

Dental chairs and handpieces demand high-speed, low-noise operation for both patient comfort and clinical accuracy.

- Application: Our 60, 62, and 68 series bearings (3mm-8mm bore) are the heart of dental handpieces, enabling high-speed rotation for drills and cleaning tools. They also support the chair's recline and adjustment motors.

- Benefit: Ultra-precise manufacturing minimizes vibration and noise, creating a better experience for patients and ensuring consistent performance for dentists.

3. Respiratory Ventilators & CPAP Machines

These life-support devices rely on constant, reliable airflow, making bearing performance critical. 

- Application: Our 60 and 68 series bearings (4mm-8mm bore) are used in the blower fans and pressure-regulating valves of ventilators and CPAP machines.

- Benefit: Low noise and high durability are essential. Our bearings ensure continuous, stable operation without failure, which is vital for patient safety.

4. Laboratory Microscopes & Analyzers

Precision laboratory equipment requires bearings that maintain accuracy and smooth movement.

- Application: Our 68 and 69 series thin-section bearings (2mm-6mm bore) are used in the focusing mechanisms and stage adjustment slides of microscopes and analytical instruments.

- Benefit: Their compact size and precise tolerances allow for fine adjustments without play or backlash, ensuring clear and accurate imaging and test results.

5. Hand Rehabilitation Robots

These advanced therapy devices help patients regain motor function through repetitive, controlled movements.

- Application: Our 68 and 69 series bearings (3mm-6mm bore) are integrated into the finger and wrist joints of robotic gloves, enabling smooth, controlled flexion and extension.

- Benefit: The low-friction, compact design allows for natural movement patterns, making therapy more effective and comfortable for the user.

6. Lower Limb Orthotic Braces

Orthopedic braces and KAFO (Knee-Ankle-Foot Orthosis) support patients during recovery from injuries or conditions affecting mobility.

- Application: Our 60 and 68 series bearings (3mm-8mm bore) are built into the hinge joints of the braces, allowing for controlled, smooth movement of the knee and ankle.

- Benefit: Our bearings provide a smooth, stable pivot point, preventing painful or jarring movements and supporting the patient's rehabilitation process. 

7. Electric Wheelchairs

Mobility devices require bearings that are both durable for daily use and efficient for long battery life.

- Application: Our 62 and 63 series bearings (8mm-12mm bore) are used in the drive wheel hubs and motor assemblies of electric wheelchairs.

- Benefit: High load capacity and low rolling resistance ensure the wheelchair moves smoothly and efficiently, extending battery life and improving the user's independence.

8. Gait Training & Rehabilitation Exoskeletons

Advanced gait training systems and exoskeletons help patients relearn how to walk.

- Application: Our 62 and 68 series bearings (6mm-10mm bore) are found in the hip, knee, and ankle joints of exoskeletons, supporting powered and assisted movement.

- Benefit: Precision-engineered for safety and control, our bearings allow for natural gait patterns, providing stable support while minimizing wear on the mechanical structure.

9. Massage & Therapy Chairs

Therapeutic massage chairs use a network of moving parts to deliver deep tissue relief. 

- Application: Our 60, 62, and 68 series bearings (4mm-10mm bore) are used in the massage rollers, track systems, and reclining mechanisms.

- Benefit: Quiet, smooth operation is key to a relaxing experience. Our bearings ensure the massage mechanisms move seamlessly, providing consistent pressure without noise or jitter.
