ABEC 5 and ABEC 7 are ratings used to indicate the precision of bearings used in machinery and equipment ABEC 7 bearings are more expensive than ABEC 5 bearings and are used in high-performance applications where precision is critical.
Material Precision: Both ABEC 5 and ABEC 7 bearings are made using quality steel; however, the ABEC 7 tends to have relatively finer material precision, resulting in better effectiveness The choice depends on the user's specific needs, with. Specifications for ABEC 7 bearings outline a more precise tolerance than their ABEC 5 counterparts, with an allowable radial run-out of 2.5 microns and an axial run-out of 1.5 microns
High Temperature Tapered Roller Bearings for Agricultural Machine ABEC5 ABEC7. ABEC 7 bearings have very tight tolerances and are capable of handling very high speeds. A 20 mm ABEC 7 bearing only has a 5 μm tolerance window, whereas an ABEC 1 has twice as wide a tolerance
High Temperature Tapered Roller Bearings for Agricultural Machine ABEC5 ABEC7. ABEC 7 bearings provide higher precision and smoother performance than ABEC 5 bearings, making them suitable for applications requiring greater speed and accuracy The ABEC scale and equivalent ISO 492 ratings are shown below: ABEC 1: ISO Class 6X; ABEC 3: ISO Class 6; ABEC 5: ISO Class 5; ABEC 7: ISO Class 4; ABEC 9: ISO Class 2; For example, on an ABEC 1 bearing with an outside diameter of less than 2 inches, the width of the outer ring can deviate within -0.0050 inches.
