Enduro Bearings 61808 VV - ABEC 5 - Ball Bearing - 40x52x7mm

Enduro Bearings 61808 VV - ABEC 5 - Ball Bearing - 40x52x7mm

ABEC 5 radial bearing with 40 mm inner diameter, 52 mm outer diameter, 7 mm thickness and extremely low friction double-lip type sealing without contact.
Developed with the idea of rolling as fast as possible, this dual lip configuration does not make contact with the bottom of the machined groove. Since these bearings also have a high rate of grease fill, the grease migrates to the bottom of the groove where a hydromatic type seal is established between the 2 lips and the grease in the groove. This grease barrier keeps the dirt and contaminates from coming inside the bearing, while still rolling smoothly and with the least resistance of all Enduro bearings.

ABEC 5 bearings use grade 5 Chromium Steel Balls and 52100 High Carbon Chromium Alloy Races.
The high precision balls are within 5/1.000.000″ round. These are military level specification, used for precision equipment. R-64 hardness, of the highest grade.
Vacuum de-gassing process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. 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.
