Precision Tolerance: ABEC 3
Steel seals:
"LLB" is a double-lip type seal making light contact and also rides in a groove making a labyrinth seal.
"LLU" is a double- lip type seal making medium contact and also rides in a groove making a labyrinth seal.
Grade 10 Chromium Steel Balls:
High precision balls are within 10/1,000,000″ round, twice as round as the industry standard, at it’s highest level.
52100 High Carbon Chromium Alloy Races:
Vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-3 precision and noiseless movement.
