Thin Section Bearings for Medical Equipment

Application

Typical Medical Equipment Applications

Medical Imaging Rotary Systems

Large-bore compact support for imaging gantries and rotary scanning mechanisms.

Surgical Equipment

Precision support for surgical robots, positioning arms and rotary instruments.

Laboratory Automation

Low-friction support for analyzers, sample handling and compact rotary modules.

Diagnostic Devices

Smooth and accurate rotation for diagnostic instruments and scanning platforms.

Patient Positioning Systems

Stable rotary motion for adjustable tables, arms and positioning mechanisms.

Requirements

Application Design Requirements

Smooth & Low-Noise Motion

Medical equipment often requires quiet, vibration-controlled and smooth rotation.

Compact Large-Bore Design

Rotary systems may need a large central opening while maintaining a small external envelope.

High Positioning Accuracy

Imaging and surgical equipment require repeatable movement and controlled runout.

Clean Operating Environment

Lubricant, sealing and cleanliness must match the equipment environment and maintenance plan.

Reliable Duty Cycle

Intermittent scanning or repeated positioning requires stable performance over many cycles.

Types

Recommended Bearing Structures

Deep Groove Thin Section Ball Bearings

Support radial loads and moderate axial loads with low friction and compact cross-section.

Angular Contact Thin Section Ball Bearings

Suitable for combined loads, higher rotational accuracy and axial positioning requirements.
