Bearing set Extralite CyberRear / CyberRear SPD-2
ABEC 5 radial bearing with 17 mm inner diameter, 26 mm outer diameter, 5 mm thickness and double-lip type sealing with light contact, making a labyrinth seal.These seals employ a snap ring that can be removed with a small knife for quick and easy servicing. These seals can be removed with no danger of bending them while performing lubrication service, ensuring they will spin as smoothly after. The single sealing lip makes contact on a step machined into the inner race, and sealing as an axial face seal. This type of seal configurations has extremely low rolling resistance and speed, while being an effective barrier against dirt and water.
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. C-3 Clearance
