ENDURO ZERØ CERAMIC HYBRID
THE BALLS are made in the USA from pure Silicon Nitride with extreme high density from uniform
compaction (3.25 g/cm3). The micro-structural development of this material during manufacture is second to none. These
high precision Grade 3, SI3N4 pure ceramic balls are 3/1,000,000” from exactly round in sphericity. They are 60% lighter
in weight, and 7 times harder than steel. Friction is reduced to near zero.
THE RACES for the ZERØ series feature vacuum de-gassed alloy steel hardened to Rockwell C-64. These high precision races
are cryogenically treated not once, but three times during the final "super polishing" phase. Cryogenic treatment
means taking the races down to minus 300º Fahrenheit to nomalize the crystalline structure of the material so that the races
will resist the hardness of the ceramic balls and get the maximum wear potential. This critical treatment to the races is
left out by many manufacturers, but not by Enduro.
THE RETAINERS are nylon with Graphite and are virtually frictionless.
THE SEALS are "VV" non-contact labyrinth type, with 2 sealing lips. They have been
upgraded from NBR rubber to silicone.
