fd90 with rim assist

Fd90 truck / bus passenger tire uniformity tester measures tire uniformity (TBR). To ensure tire quality. This is achieved by measuring, grading, marking and classifying tires according to load change, run out and sidewall appearance. The fd90 is designed to handle all truck and bus radial tires with bead diameters ranging from 16 inches to 25.5 inches. This means that a single fd90 can do the work that used to be done by multiple machines.

Fd90 was used for 100% full test. It can automatically adjust to different tire width and test environment for each tire with different bead diameter. With the rim auxiliary device, the diameter change can be carried out more quickly and conveniently. These characteristics make fd90 a very efficient detection equipment.

Changes in tire load can cause interference to driving and riding, such as vehicle vibration. The change in radial force includes the load in the vehicle as each tire rotates. When these loads occur at the natural frequency of the vehicle, they will be amplified by the vehicle suspension. The change of axial force will also cause vibration and steering deviation.

Runout is a measurement of the "out of roundness" of a tire. Radial and axial runout can also cause riding interference when each tire rotates. The sidewall appearance is the quality of a tire, which is affected by multiple tire structural features, such as sidewall splicing, carcass ply splicing, and the quality of tire components.

When the stitches overlap, when the tires are inflated, they will produce a depression in the sidewall. When the splices are not connected together correctly, they will cause expansion. These are unacceptable to the user and belong to quality defects.

To ensure good ride quality and customer satisfaction, tire and automotive manufacturers set limits on acceptable load changes, runout and sidewall appearance values. These are labeled and graded to meet the fd90 requirements

Screen diagnostics and troubleshooting tools and on-screen documentation make fd90 easy to use and service. The special maintenance access ensures easy setup, maintenance and repair. The fd90 has the best reproducibility among all machines in the industry. This means that there are very few measurement errors. More and more tires have passed the grading limit, and the yield of the factory has increased.

Through options such as rim assist, tgis-slt? (linear laser tire geometry inspection system for trucks) with hot stamp marker, fd90 is also a flexible and durable device in a strict factory environment.
