Jun 02, 2019 In many cases, full machine failure can cause your press to become permanently inoperable. More seriously, it can severely injure workers. Accidents caused by faulty machinery especially a hydraulic press can result in minor to fatal injury. The Most Common Hydraulic Press Workplace Accidents. Hydraulic presses are tools, not toys.
of the bearing races and rollers or balls is reduced, and the bearing is quickly rendered unsuitable for use. This is illustrated in Figure 11. Figures 12 and 13 show seizing damage in a roller bearing. The rollers usually are the first indicators of damage, as their corners change color due to loss of temper associated with excess temperatures.

Roller bearing failure has the potential to shut down running equipment and possibly entire plant operations. Roller bearings require lubrication to reduce the metal-to-metal friction between the rolling and sliding contact areas. Letting lubrication-related tasks lapse can ultimately mean catastrophic equipment failure.
Condition monitoring of roller press components allows for effective maintenance planning and repair, thereby minimising downtime as well as preventing unexpected failures and unscheduled stoppages. The Dalog online condition monitoring system for roller presses detects failures at the motor bearings, gearboxes and grinding rolls at an early stage.
