Thin Section Bearings for Precision Rotary Mechanisms

Application

Typical Precision Rotary Mechanism Applications

Precision Rotary Tables

Stable support for compact rotary tables and positioning stages.

Indexing Mechanisms

Repeatable angular positioning for intermittent motion and automated indexing.

Gimbals & Pan-Tilt Systems

Compact combined-load support for two-axis or multi-axis mechanisms.

Scanning Platforms

Smooth low-friction rotation for sensors, scanners and measurement platforms.

Compact Positioning Systems

Large-bore thin section support for integrated drives, encoders and cables.ms.

Requirements

Application Design Requirements

Rotational Accuracy

Precision mechanisms require low runout and repeatable angular positioning.

Rigidity & Moment Load

Overhung loads and compact structures create tilting moments.

Low Friction Torque

Smooth motion and fine positioning require consistent low torque.

Compact Large-Bore Layout

Drives, cables, encoders or optical paths may pass through the central opening.

Repeatable Duty Cycle

Indexing and scanning systems may operate in repeated start-stop 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.
