ABEC 5 angular contact stainless steel ball bearing with 24 mm inner diameter, 37 mm outer diameter, 7 mm thickness and double-lip type
sealing with light contact, making a labyrinth seal.
In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear.
Stainless steel provides maximum corrosion resistance in applications and environments where critical. It has 20% less load capacity than the 52100 chromium steel, used in most of Enduro Bearings, but with far superior corrosion resistance.
ABEC 5 stainless steel bearings use 440C steel balls and races.
The high precision balls are within 5/1.000.000″ round. These are military level specification, used for precision equipment.
Polished to a mirror finish for ABEC-5 precision and noiseless movement.
Nylon with graphite retainers are virtually frictionless while providing constant lubrication.
To meet the ABEC-5 standard, bearing design must pass all tests, which include noise testing at high RPM, extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.
