Ball Bearings

Ball Bearings main function is to minimize the friction caused by any relative movement of two or more objects, in order to reach the maximum efficiency of energy usage, we aim to minimize the "converted to heat" energy by using Ball Bearings.
A great variety of Ball Bearings types and Ball Bearings designs are known, the manifolds of the ball bearings is justified by their various purpose of the ball bearings needed application, each type of ball bearings has a certain characteristic technical properties, rolling ball bearings have the following advantages compared with the plain bearings:

• Low starting moment.
• Low friction at all speeds.
• Low energy consumption.
• High reliability.
• Small width.
• Low consumption of lubricant.
• Long relubrication intervals.
• Easy to mount and dismount.
• Standardized dimensions.
