Enduro Bearings 61805 LLU ABEC 5 Bearing - 25x35x7mm

Technologies

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.

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.

Enduro SRS Type Seals -Featured on many of our ABEC 5 level bearings, these seals employ a snap ring that can be removed with a small knife for quick and easy servicing. These seals can be removed with no danger of bending them while performing lubrication service, ensuring they will spin as smoothly after. The single sealing lip makes contact on a step machined into the inner race, and sealing as an axial face seal. This type of seal configurations has extremely low rolling resistance and speed, while being an effective barrier against dirt and water.

Features

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.

52100 High Carbon Chromium Alloy Races

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.

Graphite/Nylon Ball Retainers

Nylon with graphite retainers are virtually frictionless while providing constant lubrication.
