LYDL · BEARING INSPECTION

Quality Control

From dimensions to raceway geometry.

Explore the measuring equipment and component checks used in LYDL’s quality control work. Inspection items and acceptance criteria depend on the bearing drawing and agreed order requirements.

MEASUREMENT CAPABILITIES

Bearing inspection equipment

Each instrument answers a different question about the component. The photographs below show both the equipment and the point of measurement.

Profile and roundness measuring instruments in the inspection area.

PROFILE & ROUNDNESS

Profile and roundness measuring equipment

These instruments measure the profile of a surface section and the circular form of a component. The close-ups below show where each probe contacts the bearing component.

01 / Coordinate measurement

Dimensions & feature geometry

A coordinate measuring machine (CMM) probes points on the component to check dimensions and geometric relationships against the drawing.

Typical focus: Ring dimensions, feature positions and specified geometry.
Why it matters: Assembly fit and consistency of component dimensions.

Stylus measurement at the bearing ring profile.

02 / Profile measurement

Raceway & component profiles

A measuring stylus follows a section of the component surface, making the profile available for comparison with the specified shape.

Typical focus: Raceway contours and other specified component profiles.
Why it matters: Evaluation of the geometry at the inspected section.

03 / Roundness measurement

Circular form

The component is measured on a rotary table to evaluate departures from a circular form at the inspected section.

Typical focus: Roundness of bearing rings and other circular components.
Why it matters: Checking component form alongside other dimensional requirements.

SUPPORTING CHECKS

Closer inspection. Checks during production.

Laboratory observation and shop-floor gauging complement the measurement of component geometry.

Microscopic observation

Magnified observation supports examination of prepared samples and visible features. The inspection method and sample preparation depend on the item being evaluated.

In-process dimensional checks

Gauges support dimensional checks on bearing components during production, helping identify variation before the next operation.

QUALITY CONTROL PROCESS

From drawing review to final inspection

Inspection is linked to the component requirements throughout the production process.

Requirements review
Review the drawing, critical dimensions, inspection items and acceptance criteria.
Incoming checks
Check incoming materials against the specified material requirements.
In-process inspection
Check relevant component dimensions and geometry during manufacturing.
Final inspection
Review the agreed inspection items before protective packing and dispatch.

The inspection scope and any required reports should be agreed for the specific order.
