Thin Section Bearings for Optical Equipment

Application

Typical Optical Equipment Applications

Camera & Imaging Systems

Compact rotary support for camera platforms, lens mechanisms and imaging modules.

Optical Gimbals

High-precision support for pan-tilt and multi-axis optical positioning systems.

Laser Scanning Equipment

Smooth low-friction rotation for scanning mirrors, rotary heads and beam-positioning mechanisms.

Telescopes & Observation Equipment

Large-bore compact support for azimuth, elevation and instrument rotation.

Precision Optical Instruments

Low runout and stable motion for inspection, alignment and measurement systems.

Requirements

Application Design Requirements

Low Runout & High Accuracy

Optical systems require stable axes and minimal radial or axial error.

Smooth Low-Friction Motion

Fine adjustment and tracking require consistent torque and low stick-slip.

Large Central Opening

Optical paths, lenses, cables or sensors may pass through the bearing bore.

Rigid Positioning

Gimbals and tracking platforms require stable support against moment loads.

Clean & Stable Operation

Lubrication and sealing should match temperature, cleanliness and maintenance needs.

Types

Recommended Bearing Structures

Deep Groove Thin Section Ball Bearings

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