Enduro Bearings 686 LLU - ABEC 5 - Ball Bearing - 6x13x5mm

Enduro Bearings 686 LLU - ABEC 5 - Ball Bearing - 6x13x5mm

ABEC 5 radial bearing with 6 mm inner diameter, 13 mm outer diameter, 5 mm thickness and double-lip type sealing with strong contact, making a labyrinth seal.

The ABEC 5 Standard

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

This specification describes the internal clearance between the bearing and its race. For example, in a 10-18 I.D. bearing, our standard is 11-21 micrometers where as others use 11-25 micrometers.
All across the board, our bearings have higher standards of tolerance to ensure superior performance.
