Model Variation

Features

For balancing of flexible and rigid rotors.

•As increasing rotational speed and downsizing of machinery, relative stiffness becomes lower and lower. It causes critical speed will exist in operating speed range.
•Multi-speed multi-plane balancing method provides to defuse vibration at all operational rotating speed range.
Conventional constant speed balancing function is available.

The troublesome work of adjusting the mass of the correction weight is reduced new!

Uses up to 8 levels of correcting mass registered in advance to output the optimum component correction results.
Balancing process will become more efficient.

OK/NG judgment function according to JIS B 0905 new!

The measured value and the permissible value are compared and the OK/NG judgment is displayed.

Either the charge type or CCLD type can be selected for the vibration sensor new!

In addition to the conventional charge type vibration sensor, CCLD type vibration sensor can be selected.
In an environment where the cable is long and easy to sway, the CCLD type vibration sensor with less cable noise is suitable.

Compact and lightweight, convenient for business trips and carrying around in factories

•Battery-powered, continuous operation for 3 hours. (when sleep mode is enabled)

Easy to use & High accuracy

•Improved operability and vibration detection accuracy. (5 times that of our company)
•Save the screen as photo data to microSD.
•Equipped with overall vibrometer and FFT analyzer as standard equipment.

Unbalance correction by balance weights arrangement -optional

•Unbalance can be corrected by arranging 2 or 3 balance weights on the circumference. This method is popular for balancing of grinding wheels.
•If this method is applied to general industrial machinery, balance correction will be easily done only by rearrangement of balance weights, weight selection and/or fabrication is not needed.
•SB-7707RB series can be applied 1 plane(G) or 2 plane(GW) balancing.

Options

•Unbalance correction by balance weights arrangement
•Vibration Sensor for multi-plane measurement
