ABEC 5: A standard value used to measure the surface tolerance of rolling bearings. There are five classes: 1, 3, 5, 7 and 9. The higher the ABEC class, the greater the precision, efficiency and speed capacity, but the highest ABEC classes are not necessarily the fastest rotating components. All quality producers worldwide use at least ABEC 1 as standard. At Enduro, the minimum standard is ABEC 3. ABEC 5: Steel balls Grade 5: balls with a sphericity precision of 5/1,000,000. This is military-grade and therefore excellent for precision applications. ABEC 5 standard: this bearing must pass all tests; these include high-speed noise, very narrow tolerances concerning the accuracy of the inner and outer diameter, perfect sphericity, raceway accuracy, and the finish of both raceway and ball. These bearings are treated with a high-quality Teflon lubricant (Rheolube 374A). SRS: Mounted on most of our ABEC 5 bearings, the seals use a metal ring that can be lifted with a small knife for quick and easy maintenance. The seals can be retracted without risk of bending them during maintenance, guaranteeing that they will rotate as well as before. The unique sealing lip makes contact with the flat part in the inner ring, and the seal is like an axial surface seal. This type of seal configuration offers an efficient seal against salt and water without high frictional resistance.
