Michell Pad Apparatus
Michell Pad Apparatus (Product Code: SLE/ETM/14) is a bench-mounted, self-contained apparatus used to demonstrate the pressure distribution across the oil film in a Michell tilting pad slider bearing in engineering laboratories. Students read oil pressure on a set of thirteen graduated tubes while adjusting pad tilt and belt speed. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Michell Pad Apparatus Used For?
Large thrust bearings in turbines and ship propeller shafts rely on the tilting pad principle: a slightly inclined pad drags oil into a converging gap, and the wedge of oil builds enough pressure to carry the load without metal-to-metal contact. On this apparatus the moving flat belt plays the part of the runner, the aluminium pad sits above it, and the oil film forms in between, so the whole effect can be seen and measured on a bench.
Students set a tilt with the eccentric shafts, record the leading and trailing edge positions with the micrometers, and read the thirteen tubes to plot pressure under the pad. Changing the belt speed and measuring the oil with the included viscometer then links sliding speed, viscosity and film thickness to pressure distribution — a clear viscosity measurement and lubrication practical for engineering colleges. Keep the oil container closed between sessions so the oil stays clean.
OEM Manufacturer
The Michell Pad Apparatus comes from Jain Scientific Equipments Private Limited, trading as ScienceLab, which manufactures it as the OEM at its own licensed factory at Saha, Ambala, Haryana, India. Laboratories, dealers and importers order it straight from the manufacturer, and questions about oil, tubes or other replacement parts go to the same team — ask us.

Frequently Asked Questions
What does the Michell Pad Apparatus demonstrate?
The Michell Pad Apparatus demonstrates the pressure distribution across the film of oil in a Michell tilting pad slider bearing. Students find how pressure distribution relates to film thickness, sliding speed and oil viscosity.
How is the oil pressure measured?
On the Michell Pad Apparatus SLE/ETM/14, a set of thirteen graduated tubes shows the oil pressure across and along the film under the pad. Readings from all the tubes let students plot the pressure profile for each set-up.
Can the pad angle and belt speed be changed?
Yes. On the Michell Pad Apparatus, two eccentric shafts hold the pad so the angle of tilt can be adjusted, and micrometers measure the leading and trailing edge positions. A variable speed control sets the speed of the motor that turns the belt.
Is oil supplied with the Michell Pad Apparatus?
Yes. A container of oil and a viscometer to measure the viscosity of the oil are included with the Michell Pad Apparatus. For repeat supplies of oil, ask us when you place or plan your order.
Who manufactures the Michell Pad Apparatus?
The Michell Pad Apparatus SLE/ETM/14 is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its licensed factory at Saha, Ambala, Haryana, India. Quotations and after-sales enquiries are handled by the maker directly.
