Enduro 2437 24x37x7 ABEC 3 BB90
Description
Direct OEM replacement for most BB86/92, Trek BB90/95
- 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
- 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.

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$11.21 (RRP)Add To Cart

Pivot bearings are exposed to a vast range of dirt, water, sand and other abuses. We have designed our MAX type bearings to handle these extreme conditions and use them in all of our suspension kits. They have a 35-40% higher load capacity than the standard retainer type bearings most people sell. We also pack them on both sides with a high impact, water proof grease.
The result for you is a much more active and quick rear suspension, eliminating play and wag all at the same time. Upgrading your rear suspension with Enduro Bearings MAX bearings will save you time and money, as they will perform well 2 or 3 times longer than the stock set up.$39.62 (RRP)Add To Cart

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.
