High Temperature Roll Stability Tester with adjustable speed controller (100 to 200 rpm) for shear stability testing lubricant greases by simulating the effect of squeezing grease between the rollers and the outer face of a roller bearing.
High Temperature Roll Stability Tester with adjustable speed controller (100 to 200 rpm) for shear stability testing lubricant greases by simulating the effect of squeezing grease between the rollers and the outer face of a roller bearing.
The unit allows up to four test cylinders to be used simultaneously. Each test cylinder contains a heavy roller and is loaded with a quantity of the sample grease. The test cylinder rests horizontally upon a set of driving and guide wheels which rotate the cylinder.
A digitally controlled fan assisted air bath is closed over the cylinders to provide evenly distributed heating up to 200 °C, and an integral timer is used to set the test duration.
Note: Cylinders and Rollers supplied separately.
