Description
Product Overview

The BD-1831 Roll Stability Apparatus for Lubricating Grease conforms to ASTM D1831, the Standard Test Method for Roll Stability of Lubricating Grease. The test begins by determining the cone penetration of an approximately 50 g aliquot of lubricating grease. The grease is then subjected to low shear at 20 to 35 °C (68 to 95 °F) for 2 h ± 5 min in a standard roll stability apparatus, after which the cone penetration is measured again. The difference between the cone penetration before and after working serves as a measure of the effect of flow shear working on grease consistency. This apparatus is suitable for testing the consistency change of lubricating grease after working on the roller tester, allowing evaluation of the mechanical shear stability of the grease.

Key Features
  • Digital timer for recording test duration, equipped with an audible alarm.
  • Belt-driven drums for reliable, consistent operation.
  • Capable of testing two drums simultaneously.
  • Instrument housing lid features a thermometer port for temperature calibration; idler rollers are fitted with positioning rings to ensure proper drum operation.
  • Microcomputer temperature controller with digital display and PT100 sensor; accuracy: ±5 °C.
  • Balanced cast-aluminum fan and 800 W heater ensure efficient and uniform heat distribution.
  • Microprocessor-based PID control enables rapid and stable heating, while an overheat protection circuit safeguards the unit.
