Bearings

Enduro ABEC-3 bearings start with high-precision Grade 10 Balls are ground within 10/1,000,000? round, which is twice as round as the industry standard, at it’s highest level.

Enduro Bearings uses highest quality 52100 High Carbon Chromium Steel Alloy race material from Japan. There are many suppliers of 52100 material, but they do not all necessarily provide the same quality material. The material for Enduro steel races starts with and extremely-pure, vacuum de-gassed chromium steel alloy that is then hardened to Rockwell HRC 64 by multiple rounds of heat and cryogenic treatment. The material is then cut to size and the races are machined, ground and polished to a mirror finish for ABEC-3 precision and noiseless movement.

Enduro ABEC-3 bearings also feature riveted steel bearing retainers for toughness, and are noise tested to meet or exceed ABEC-3 tolerances

Enduro LLB Type Seals

Our most popular seal type, this is a Nitrile material rubber with a steel insert. Rather than the standard 2RS type seal, we go a step further by machining a groove into the inner race where the seal can rotate with better efficiency and less rolling resistance. Rather than one thick seal lip rubbing on a blunt surface, LLB type utilizes two razor thin sealing lips riding in the groove with light contact. The outside lip keeps the water and contaminates out, while the inner seal retains the grease for smooth function and long intervals between servicing.

We don’t mess around with inexpensive headset bearings at Enduro Bearings, it’s simply not worth it. While many headset makers will offer you Cr-Mo or standard steel headsets for your carbon road bike, steel cross bike, or full suspension mountain bike, we feel that’s like putting bias ply tires on a rally car. We don’t offer the entry level for headset bearings. Instead we begin with chromium steel, Black Oxide finish A/C type and then offer full 440C stainless steel at the top. They are always engineered with the largest balls possible and dual lip seals riding in a micro groove for ultimate protection against sweat and the elements. They are filled 90% with high pressure water proof grease, so you don’t have to ever guess if there is grease inside. Watch for more headset related components and even larger selection of sizes in 2016 from Enduro Bearings.

Lower bearing is MR137

Enduro Bearings manufactures some series of bearings using 440C stainless steel balls and races. This material provides maximum corrosion resistance in applications and environments where critical. Depending on the application, they are designed to ABEC-3 or ABEC-5 tolerances. Stainless steel has 20% less load capacity than the 52100 chromium steel, used in most of our bearings, but with far superior corrosion resistance.
When the rain won’t go away, and your bicycle is more often used as a boat rather than a land craft, you may want to consider 440C stainless steel bearings. While a little softer than chromium bearing steel, 440C stainless steel is a good alternative in constant wet conditions, or where sweat becomes a problem such as headset bearings. Enduro Bearings uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements.

- Black Oxide bearing which get an additional Magnetite treatment for hardness, rust resistance and even more reliability.
- Double Row Bearings

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.

Enduro LLU Type Seals

Similar to the LLB type seal, LLU is a full contact, dual lip seal riding in a groove on the inner race. With more sealing pressure, these are ideal for pivots or headsets that continually come in contact with dirt, sweat, and dust. The increased seal pressure and 2 lips help retain the 90% grease fill we use on these bearings to better displace any moisture and continually lubricate the balls and races.
