With consistent focus on our quality, we are offering a wide range of IRHD Rubber Hardness Tester. This is use to find out the suitability of any rubber component for its intended end use, our professionals use quality tested components and advance technology for manufacturing this hardness tester. Along with that, we are giving this hardness tester after checking properly against diverse quality parameters.

Features:

  • Heavy duty design
  • Require less maintenance
  • Smooth functioning

Other Details:

  • An electric buzzer is provided to give low intensity vibrations to the plunger rod to eliminate friction.
  • The dial indicator gives the depth of indentation in units of 0.01 mm, which can be converted into IRHD hardness values with the help of a standard table provided with the equipment. 
  • The tester is finished in grey hammertone stoving painting and bright chrome plating to give it a corrosion resistant finish. Three models of the tester are available to cover different ranges of hardness.

Shear Fatigue Tester

Shear Fatigue Tester

Product Price : Get Latest Price
The Shear Fatigue Tester for polyurethane foam consists of a reciprocating platform on which the test specimen can be held, a cylindrical roller to compress the test specimen, and an arrangement to either produce a constant deflection of the test specimen or to apply a constant load on it.The reciprocating platform is made of cast aluminium and is moved in a horizontal plane with the help of a motor, worm reduction gearbox, and a link. It moves on four wheels having ball bearings. The wheels run on two metallic rails. The platform has a large number of holes on its upper surface for rapid escape of air during compression. The test specimen is held on the platform with the help of either a double-sided adhesive tape or by holding fabric strips pasted on its ends under two bar shaped grips.

Other Details:

  • The cylindrical roller is made of stainless steel and rests on the surface of the test specimen. Its axis is inclined at 15° to the direction of motion of the platform. The roller is mounted on two ball bearings and is held on the ends of two levers to permit a hinged vertical movement.
  • The desired deflection is given by placing dead weights above the cylindrical roller. Test under constant deflection are conducted by restricting the vertical movement of the roller with the help of two adjustable knurled bolts. Tests under constant load are conducted by placing desired dead weights above the roller.
  • A five digit pre-set type electronic counter with non-volatile memory is provided to record the number of compression of the test specimen and to automatically stop the motor after the desired number of compressions.
  • The apparatus is finished in grey hammertone stoving painting and bright chrome / zinc plating to give it a corrosion resistant finish.

Technical Details:

Flexing frequency28 cpm
Movement of platform330 mm
Dimensions of the roller75 mm diameter, 460 mm length
Dimensions of test specimen380 x 380 mm
