GREASE ROLL STABILITY TEST APPARATUS - (ASTM D1831) - 4 CYLINDERS

Model No: EIE-PTGT-137C04

Compliance Standards : ASTM D1831, MIL G 10924. Detailed Specification as follows:

Compliance Standards:

ASTM D1831, MIL G 10924


Purpose:

This test method covers determination of the changes in the consistency, as measured by cone penetration, of lubricating greases when worked in the roll stability test apparatus. Simulates the effect of squeezing grease between the rollers and the outer race of a roller bearing.


Construction Details:

  • Specially designed for long runs at elevated temperature (50°C). Can go beyond 50°C on special request from customer end at extra cost.
  • Excellent heat uniformity due to fan assisted air circulation
  • Factory adjusted overheat cut‑off system
  • Automatic cut‑off whenever cover is lifted
  • Heaters and drive chain mechanism are shielded for operator safety.
  • Stainless steel cylinder containing the test grease
  • Fitted with stainless steel roller which rotates within the cylinder
  • Base with roller supports allowing the rotation
  • Adjustable rotational speed with RPM Display
  • Delivered with 4 rolls, 4 cylinders, tools for closing and opening cylinders
  • Insulated steel cabinet and base are finished with a durable polyurethane enamel finish
