Rubber in Shear Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-ELA-5516
Jlab Export is a leading Rubber in Shear Apparatus Manufacturer,and suppliers in India
Rubber in Shear Apparatus (code EL-ELA-5516) is a wall-mounted strength of materials apparatus for finding the modulus of rigidity of rubber. A 150 x 75 x 25 mm rubber block bonded between two aluminium alloy plates is loaded in shear by a weight hanger, and a dial gauge measures how far it deflects. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Rubber in Shear Apparatus Used For?
Rubber blocks loaded in shear are widely used in engine and equipment mountings to isolate vibration, absorbing shock energy by deforming. This apparatus lets students load such a block in shear and measure its deflection. Plotting deflection against load, and then shear stress (load over the bonded area) against shear strain (deflection over the block thickness between the plates), gives the modulus of rigidity of the rubber from the slope of the line.
The listing also notes that as the block lengthens its cross-section decreases, an effect described by Poisson’s ratio, and that rubber, which most people think of as ‘elastic’, is in engineering terms less elastic than steel and often shows a high degree of hysteresis, so loading and unloading readings can differ. It is used in strength of materials and mechanics of solids labs in mechanical and civil engineering degree and diploma courses.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Wall space — the apparatus is wall mounted, so plan a wall position where students can load the hanger and read the dial gauge.
- Other strength of materials experiments — torsion and shear centre apparatus are separate items that can be quoted on the same enquiry.
Frequently Asked Questions
What does the apparatus measure?
The shear deflection of a rubber block under load, read on a dial gauge. From the load–deflection readings students find the relationship between shear stress and shear strain and the modulus of rigidity of the rubber.
What size is the rubber block?
150 x 75 x 25 mm, bonded to two aluminium alloy plates.
How is it mounted and loaded?
One plate is screwed to a wall, and a shear load is applied to the other plate by a loaded weight hanger.
Why do loading and unloading readings differ for rubber?
Rubber often shows a high degree of hysteresis: some of the energy put in while loading is lost as heat, so the unloading curve does not retrace the loading curve. That same energy absorption is why rubber mountings damp vibration.
Is an instruction manual provided?
Yes. A complete manual describes the apparatus, its application, the experimental procedure and typical test results.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and the tender reference if the order is for a tender.
Who manufactures the rubber in shear apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of engineering teaching apparatus in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The apparatus is built at JLab’s own works rather than bought from a trader, so engineering colleges, polytechnics, dealers and importers buy it factory-direct, each unit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. Its GSTIN is 06AADCJ9848D1ZE and its Legal Entity Identifier is 549300DTGS77DGYD6N03. JLab exports worldwide and ships to buyers in every region — for example the Maldives in South Asia, Portugal in Southern Europe, Morocco in North Africa, Saudi Arabia in the Middle East and Cambodia in Southeast Asia. Tender information is on the JLab lab tenders page.
Other Strength of Materials Apparatus
