Balancing machine CAROBA® Balancer Universal 500

The universal balancing system for high precision

Components for high speeds in particular benefit from precise balancing, the balancing speed is usually also in the higher range. Our CAROBA® Balancer Universal 500 extends the application range to the balancing of fast running workpieces in the production area. A conveniently operated hood protects the operator. The magnetic locking device only permits opening when this is safely possible.

The unbalance measuring system CAROBA® UMS, the base structure is at the same time an integrated switch cabinet for drive components, pneumatics and control. Solutions for automation support the balancing of large quantities in series production. The various setup variants for different workpieces are fully compatible with the OnDesk 500 worktop version. You can operate the balancing system and evaluate the measurement data either via a comfortable operating terminal with screen and keyboard or a laptop. Both versions are mounted on a robust swing arm.

Basic System

The basic system of the balancing machine CAROBA® Balancer Universal 500

The basic version of the Universal 500 consists of a sturdy base with integrated switch cabinet, protective hood with solenoid interlock and 4 adjustable feet (on request with lockable castors or lifting rollers).

For driving your workpieces, a powerful round belt drive including drive arm is integrated (on request incl. positioning of the workpiece, also known as "turning in"). For fixing the optional set-up variants, there are 2 movable and removable clamping blocks on the freely mounted system rail. A mounting strip is available behind the system rail to mount accessories (triggers, stops, etc.).

You can operate the balancing system and evaluate the measurement data either via a comfortable operating terminal with screen and keyboard or a laptop. Both versions are mounted on a robust swing arm.

Equipment options

Bearing blocks and belt drive

In this setup variant, roller blocks or plain bearing blocks are mounted on the clamping elements of the system rail. The drive is realized with round belts, on wish incl. positioning of the workpieces for the mass correction. The adaptation to different workpieces can be carried out quickly - the experience of PMB contract balancing has been integrated into the development of this system.

Use it to balance components without their own bearings and drive, e.g. shafts, electric motor rotors, turbo rotors, etc.


Balancing platform for assemblies

Instead of the bearing blocks, you can also mount your runnable assemblies or your own mounting fixtures directly. If your workpiece has its own bearings and drive, e.g. spindles, electric motors, small blowers, fans, etc., you can set these up in just a few minutes.

The drive control of the balancing stand takes over the control of your own drive unit. This is done via the 0-10 V DC setpoint output. Other drive types, e.g. an air drive, can also be operated.


PMB air bearing with air drive

If workpieces are to reach very high speeds in the later operation, they must be balanced particularly precisely. A very good solution is balancing on our PMB air bearings and air bearing mandrels. With this technology, residual umbalances of less than 0.001 gmm are achieved. The air bearing works contactless and therefore extremely gentle for the workpiece to be balanced. This procedure is very well suited for balancing industrial series, as the achieved balancing qualities are outstandingly reproducible.

Balance e.g. turbo rotors, compressor wheels and all workpieces that have a good and smooth shaft surface or borehole. We would be pleased to advise you on this fascinating technology for balancing in air bearings.
