Understanding the Difference Between Precision and

The bearing’s ABEC rating describes the level of manufacturing tolerances. The higher the rating the higher the precision. Ball bearings made with precision levels less than ABEC-1 are considered unground bearings. If a design uses ABEC-1 level bearings or higher there is a good chance there may be a more economical bearing solution for the

Ball Screw: What Is It? How Does It Work? Lead Screws

Ball Bearings. The ball bearings, or the balls, are the most prominent component of the ball screws that moves between the clearance of the nut and the shaft. They make up the component dedied to reducing the friction generated by the nut and the moving screw; this friction would be too great if the balls were not present in the screw assely.

Precision Vs. High-Precision Bearing - Bearing Tips

Jul 18, 2016· A precision bearing is anything that has a higher standard precision level (i.e. ISO P5 or ABEC 5). The step up from this is super-precision bearings that have a precision level of ISO P4 or ABEC 7 or better. For an easy way to remeer this think: Precision = ABEC 3+ Super Precision = ABEC 7+ Or, refer to this chart.

Ball Bearings vs Roller Bearings: How Are They Different

Feb 27, 2020· Ball bearings are more forgiving when it comes to angular misalignment. Roller bearings, much less so. While a ball bearing can handle a misalignment of up to 0.004 inches, a cylindrical roller bearing might already have difficulty rotating when misaligned by anything more than 0.001 inches.

Bearing Grades and Quality - Fit Werx

ABEC grading considers the precision of the rings (races) that the bearings roll on, but not the precision of the balls. The ABEC scale rates bearing precision on four levels: 1, 3, 5 and 7. ABEC 1 is the lowest level of bearing that is considered “Precision”. ABEC 1 bearings are specified on three variables:
