Aire Velo Bearings offer a comprehensive range of MAX complement bearings, also known as full complement bearings. Our product range covers the variety of bearings found within suspension swing arms on full suspension mountain bikes.
MAX complement bearings are made with steel inner and outer races and rubber seals (2RS). They are packed to full capacity with as many balls as possible, without any cages separating them. This means the bearings can take greater loads.
Bearings in suspension swing arm systems never do a full rotation, meaning no cage separation is required to achieve high rotational speed. MAX complement bearings can take a real hammering and can take an increased load due to the application and usage of full suspension mountain bikes.
Some of the bearings come with extended inner races on one side or both sides, which helps with spacing (depending on where they are installed on the bike). Some of the dimensions enable you to see this, such as the 698-2RSE MAX (8x19x6/7.5), where the E suffix refers to the extended race.
The real term for MAX complement bearings is full complement bearings. The word ‘MAX’ comes from Enduro, who managed to Trademark the term 'MAX'.
MAX complement bearings have no retainers/cages, meaning more balls can be packed inside. Compared to bearings with cages, full complement bearings have an increased load capacity of around 40% or more. This type of bearing is highly suited to suspension pivots on mountain bikes, where there is a higher load and a lower rotation rate.
The whole point of MAX complement bearings is that more balls allow for greater strength in lower rotation, high load applications.
Full (or MAX) bearings also differ from 2RS bearings because they have a high contact dual lipped labyrinth seal, which basically means the seal has 2 lips. The two lips fit neatly into a matching groove on the inner race of the bearing. The outer seal is given the job of repelling outdoor contaminants, like water and mud, while the job of the inner seal is simply to retain the marine quality grease that keeps everything running smoothly.
The MAX complement bearing is regarded as one of the best bicycle bearings on the market today, especially for suspension pivots on mountain bikes. The race grooves and a bit deeper than other bike bearings within our range, offering more lateral support for the twisting and forces associated with mountain bike pivots. With superior sealing and load capacity, these types of bearings are a mountain bikers dream come true.
