Original Enduro single row ball sealed MAX bike bearing 17mm inside x 30mm outside x 7mm width, also known as 69032RSMAX, 6903LLUMAX

Designed specifically for suspension pivots, Enduro Bearings pioneered MAX type bearings almost 20 years ago for bicycles to address the challenges associated with mountain bike pivots. These bearings have 35-40% more load capacity than standard radial bearings. We accomplish this with a special design where the maximum number of balls are inserted into the bearing. The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with mountain bike pivots. LLU seals give maximum protection against the elements, while keeping the 90% fill of Almagard Extra High Pressure Grease inside.

Also available now are MAX BO bearings which get an additional Magnetite treatment for hardness, rust resistance and even more reliability.

Enduro also make Angular Contact MAX type bearings, in both sealed and greaseable types. These bearings are spec'd on some of the best mountain bikes available, and you can also get them from us for replacement, or for building your own custom mountain bike. We supply to almost 100 companies with bearings of various designs. We work directly with frame builders to get every detail right.

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

ABEC Rating
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
