Static and Dynamic Balancing Apparatus
Product Code : LSK-TOMLE-10617
Static and Dynamic Balancing Apparatus (SKU LSK-TOMLE-10617) lets students balance a rotating shaft carrying four eccentric blocks, first statically and then while it spins. It is a standard dynamics-of-machinery practical for B.Tech mechanical students and diploma courses. The apparatus is manufactured by Science Lab Supplies in its own works at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which quotes colleges, polytechnics, contractors and distributors directly.
Specifications
A stainless-steel shaft is held in a rectangular frame that hangs on chains, carrying four stainless-steel blocks of different eccentric mass on clamps. Angular and longitudinal scales set each block's position, and a variable-speed FHP motor with speed controller spins the shaft. The frame is painted.

Applications and Experiments for the Balancing Apparatus
Students find the relative out-of-balance of each block by counting steel balls in the container, draw a moment polygon to fix the blocks' angular and axial positions, and then run the shaft to confirm it spins smoothly. Running with blocks out of position shows the effect of unbalance.
- B.Tech/B.E. mechanical, Dynamics of Machinery: static and dynamic balancing of rotating masses.
- Diploma mechanical engineering: observing vibration caused by unbalance.
- Graphical practice: force and couple (moment) polygons for balancing.
- TVET mechanical technology: vocational training equipment for machine dynamics.
Tighten every block clamp before starting the motor, raise speed slowly and keep hands clear of the rotating shaft.
Standard Scope of Supply
Each apparatus comprises the stainless-steel shaft in its chain-suspended frame, four eccentric balancing blocks with clamps, the cord and container system for static weighing, angular and longitudinal scales, and the FHP motor with speed controller, all on the painted structure.
Packing, MOQ and Lead Time
Institutes looking for a TVET lab equipment supplier can ask for one apparatus or a full theory of machines lab. Each quotation gives packing, delivery time and price for the quantity, and the gyroscope, governor and gear-train units from the same range can be added.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Enquiries go through the contact page or the enquiry cart; the lab tender page covers tenders.
Frequently Asked Questions
How is static balance measured on this apparatus?
Each block is clamped on the shaft in turn and its out-of-balance is measured with the cord and container system, counting the steel balls needed to balance it.
What power supply does it need?
The listed electricity requirement is 0.5 kW at 220 V, single phase, for the variable-speed FHP motor.
Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer: the apparatus is built in Saha, Ambala, India, and colleges or contractors deal with the maker directly for quotations.
Why is the frame hung on chains?
Chain suspension lets the frame move freely, so any remaining dynamic unbalance shows up clearly as vibration when the shaft is spun.
