Original Enduro single row ball bearing with SRS removable seals 12mm inside x 24mm outside x 6mm width, also known as 6901SRS
Enduro's ABEC 5 is the next performance step up from the popular ABEC 3 range. By using military level, high precision HRC-64 hardended Grade 5 Chromium Steel Balls, and 52100 High-Carbon Chromium-Alloy mirror polished races. This combination allows Enduro's ABEC 5 bearings to use tolerances twice as tight as ABEC 3, and operate without any noise. The Graphite/Nylon ball retainers allow virtually frictionless movement and provide constant lubrication to maximise the life of the bearing.
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.
