Condition: new, Cardan shaft balancing machine BVI-03-74 Available in stock in Poland !!! Delivery time: one day!!! . . Machine for driveshafts weighing up to 150kg and up to 4700mm long. Suitable for small workshops with a large range of different shafts, including trucks. This balancing machine has high productivity and serves to balance the cardan shafts of cars and trucks. It makes the process of balancing the cardan shaft easy thanks to many technical solutions, while the machine has an affordable price, which reduces your financial burden and allows you to develop your business effectively. . . TWO TIMES faster than your machine. Gjdpfopbv Tfjx Aftskf This balancing machine is majored to balance the shaft not only qualitatively, but also quickly. If you can balance in 2-2.5 times faster, then this is your real competitive advantage. . . HIGH PERFORMANCE ACCESSORIES The machine is equipped with three main types of adapters: 1. Fast clamping universal adapters. It has two main advantages: The first is that due to the special design the driveshaft flange is clamped within 5 seconds. This advantage is due to the fact that the driveshaft flange does not need to be fixed with bolts. THE SHAFT CAN BE CLAMPED 4 TIMES FASTER WITHOUT BOLTS. The second advantage is the centering rings. The driveshaft is mounted in the adapters with centering rings that can be made on an ordinary lathe to fit most common driveshafts. 2. KV Flange adapters. Used for balancing shafts with cross-tooth flanges. Applies to four flange sizes: 120, 150, 180, 205 mm. Usually used on truck driveshafts. 3. Adapter with slots.

Condition: as good as new (ex-display), Compact balancer with vertical spinning axis and load capacity up to 50 kg. Thanks to its compact design, the machine takes up relatively little space and does not require foundations, so it can be easily relocated to the desired location. The balancing process is controlled by the latest measuring system "ROTORTEST 9.5" with dedicated software equipped with workshop programs, which convert the unbalance into a convenient correction method, e.g. into drilling or milling parameters. Vertical axis balancing machine is recommended for balancing rotors mounted on a bore, e.g. fan rotors, pulleys, flywheels, tools, pumps and many others. The biggest advantages of this type of balancing machine are its universal application, the possibility of using dedicated self-centring chucks giving high measuring accuracy, simple and quick calibration method, so called "manufacturer's calibration", which does not require calibration runs to be carried out before starting the measurements. The whole procedure consists only in entering basic rotor parameters into the software.

Condition: new, workpiece weight (max.): 10,000 kg, rotor diameter: 2,500 mm, Horizontal soft-bearing Balancing machines 9K719 with load capacity from 100 to 10000 kg are designed for high-precision balancing of rotors of electric motors, pumps, compressors, blowers and exhausters, gearboxes, turbines of power engineering. Self-aligning rollers ensure proper rotor alignment, simplifying setup and reducing balancing time. Combined Drive System has a unique configuration with two axial drives and a belt drive mounted on a single bed. Overall, this machine is highly versatile and effective in balancing various types of rotors, making it ideal for repair and production shops. HIGHLIGHTS • Soft-Bearing System: This system ensures linear sensitivity across the entire speed range during balancing. The result is exceptionally high balancing accuracy, achieving up to 0.04 g·mm/kg across all rotor mass ranges. • Self-Aligning Roller Cassette automatically adjusts to the rotor along two axes, eliminating the need for precise centering. This design reduces machine setup time and, consequently, the overall time required for balancing. • Wide Contact Area Rollers: The cylindrical rollers provide a broad contact surface, preventing scoring or deformation of the rotor's support surfaces. This is crucial when balancing heavy rotors for extended periods, minimizing the risk of damage due to prolonged contact or improper loading. • Combined Drive System: Rotors of relatively low mass can be driven by “belt drive”, which makes the machine more versatile and allows balancing a very wide range of parts. Heavy rotors are rotated by "axial drive" using a cardan shaft. • Rotor Jacks: Specialized loading devices can be integrated to ensure smooth and precise rotor placement onto the roller supports. This minimizes the risk of damage to the delicate roller assembly, particularly when handling heavy or sensitive rotors. • High balancing accuracy due to automatic calibration of the balancing machine directly for each rotor by determining the influence coefficients. Its ease of use, high measurement accuracy, and integrated specialized features enable balancing professionals to achieve outstanding results in the shortest possible time. • The frequency converter drive provides smooth acceleration and deceleration of the electric motor and infinitely variable speed control of the rotor. Gkjdpfxjwdgpto Aftof • No need for special foundations and vibration isolation, no need to fix the machine to the floor.
