What is the difference between LLB, LLU & VV seals?
The "LLB" & "VV" seal is a non-contact seal for reduced torque or higher speed requirements. The "LLU" seal is contact seal for better grease contamination control, but the contact friction increases torque and lowers the limiting speed.
"2RS" literally means "Two Rubber Seals"
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.
Riveted Steel Retainer for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance
The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). There are five classes from largest to smallest tolerances: 1, 3, 5, 7 and 9. The higher ABEC classes provide better precision, effciency and greater speed capabilities
ABEC 1 = normal industry standard, least expensive and least accurate
ABEC 3 = class 6 Enduro minimum standard
ABEC 5 = class 5
ABEC 7 = class 4
ABEC 9 = class 2
