Cooling Fan Engineering
Thermal Design

[ Cooling image ]

In the very early stages of system design you will be planning not only for adequate space and power for the cooling fan, but also optimum airflow to heat generating components. The first stage in designing a forced air cooling system is to estimate the required air flow.

Ball Bearing Engineering
Designing to Lower Cost

The majority of bearing applications can be effectively handled using a "standard bearing". A standard bearing in this case, refers to a ball bearing that is in such worldwide demand that large volumes are produced. This virtually guarantees continuity of supply while assuring pricing benefits.

Step Motor Engineering

[ Basic step motor system ]Step motors convert electrical energy into precise mechanical motion. These motors rotate a specific incremental distance per each step. The number of steps executed controls the degree of rotation of the motor's shaft. This characteristic makes step motors excellent for positioning applications. Step motors have several advantages over other types of motors. One of the most impressive is their ability to position very accurately.
