Gears are machine components that mesh with toothed parts to transmit torque, and they serve as a crucial part type for countless machinery equipment, vehicles, appliances, and more. Bevel gears in particular are a specific gear type that are used in applications where there is a need for changing the axis of rotation for a shaft. A bevel gear system can feature various bevel gear variations, though most are cone-shaped gears which transmit their power between two intersecting axes. Bevel gears are used in many powered tools and automotive assemblies, thus being aware of their common types and how they are used can be very beneficial.

Hydraulic power units (HPUs), a type of ground support equipment, are crucial for the testing and maintenance of aircraft systems. But like any machine, they cannot be used if they are not in peak condition. This is where preventative maintenance comes into play. By maintaining your HPU prior to its breaking down, you will be able to rely on it whenever you need it. In this blog, we will look at the four most important aspects of HPU maintenance: checking and changing oil, cleaning filters and strainers, checking for leaks, and lubricating the motor.

Temperature sensors have a wide range of uses in many different applications. Some devices, like the equipment used to produce life-saving medicine, require highly accurate and responsive temperature sensors. On the other hand, applications like the thermometer in your car do not need to be as accurate or responsive. As such, there are many types of temperature sensors with varying accuracy and responsiveness. The four most common types of temperature sensors are negative temperature coefficient thermistors, resistance temperature detectors, thermocouples, and semiconductor-based sensors.
