Enduro ABEC5 bearing MR 1526 LLU/LLB Dual Seal Technology 15x26x7mm 12.4g

Balls:
Grade 5 Chromium Steel Balls
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.

Races:
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-5 precision and noiseless movement.

Retainers:
Graphite/Nylon Ball Retainers
Nylon with graphite retainers are virtually frictionless while providing constant lubrication.

The ABEC-5 Standard:
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.

Seals:
LLU/LLB Dual Seal Technology
Our newest addition to our ABEC-5 line is the new LLU/LLB dual seal bearings.
The ABEC-5 Dual Seal bearing places a LLU medium contact seal on the outside facing surface of the bearing, while the Inboard facing LLB medium contact seal offers less drag.
These specific seal increase the lifespan of the bearing and offers excellent performance.
