How to choose Belt alignment devices

Points to check when selecting, with the values for this product (TKBA 21).

  1. 1. Measuring distance suited to pulley spacing

    This product: Measurement Distance 50 – 3 000 mm

    Each tool has an upper limit on the pulley center distance it can measure, and some listed products cover up to 6 m. Check the shaft center distance of the target equipment and select a model that fits with some margin. For long equipment spans or outdoor use, also confirm that the laser remains easy to see.

  2. 2. Angular misalignment measurement accuracy

    Angular misalignment, meaning twist or tilt between pulleys, is a main cause of uneven belt wear and belt derailment. Compare the tool's angular measurement accuracy with the allowable angle specified by the belt manufacturer to confirm it is fine enough. The longer the shaft center distance, the larger the end deviation caused by even a small angular misalignment.

  3. 3. Parallel misalignment measurement accuracy

    This is the accuracy for measuring the amount by which pulley faces are offset parallel to the axial direction (offset). The allowable offset differs by belt type, so confirm that the readable accuracy is sufficient for the allowable value of the belt in use. Accuracy varies by model, so compare the specified values.

  4. 4. Compatibility of mounting method and pulley shape

    The magnet mounting method requires a flat, magnetic pulley side face. For the groove-fit method, check that the V-guide size or adapter matches the target groove. Whether a model can be used with multi-rib pulleys or sprockets also varies by model.

  5. 5. Selection of laser color and configuration

    Green lasers are easier to see than red lasers in bright locations, making them suitable for outdoor work or long equipment spans. Configurations include a transmitter combined with a target, and a two-unit setup of transmitter and receiver. Also consider whether adjustments are needed at the same time as belt tension adjustment.

  6. 6. Continuous battery operating time

    Listed products have continuous operating times of about 6 to 20 hours, and some models run longer. When adjusting multiple equipment units in succession, or when batteries are difficult to replace on site, a model with longer operating time avoids interruptions to work. Also confirm the compatible battery type.
