Enduro Bearings ABEC 5 Bearing

Enduro has many years of experience in making bearings for industrial applications. You will also notice that with these extremely smooth-running Enduro Bearings ABEC 5 Ball Bearings. These bearings are treated with a high-quality Teflon lubricant (Rheolube 374A) for low rolling resistance and a long life. Most ABEC 5 bearings are fitted with SRS seals. This seal can be lifted with a knife point, making the bearings quick and easy to service. The seal against water and dirt remains guaranteed. ABEC 5 bearings have to pass many tests: noise at high speed, very tight tolerances in inner and outer diameter accuracy, perfect spherical shape, trajectory accuracy and both trajectory and bullet finish. The Abec 5 bearings are available in many sizes and therefore suitable for almost every wheel.

GRADE
Bullets are classified according to their grade. A grade 5 bullet means its spherical tolerance is 5/1,000,000 and as such extremely round. Another characteristic of a Grade 5 bullet is the surface finish of less than 0.005 microns which, in this case, involves very close tolerances. The lower the grade, the better the bullet quality.

ABEC
A standard value used to measure the tolerance of the surface of the roller bearings. There are five classes: 1, 3, 5, 7 and 9. The higher the ABEC class the greater the precision, efficiency and speed capability, but the highest ABEC classes are not necessarily the fastest rotating parts. All quality products around the world use at least ABEC 1 as standard. With Enduro the minimum standard is ABEC 3. The Enduro Bearings ABEC 5 bearings have standard ABEC 5.
