14x25.8x6 mm Ceramic Engine Bearing - Ceramic Engine Bearing by ACER Racing

Description

14x25.8x6mm ceramic engine bearings featuring World Champion ACER Racing's diamond polished Silicon Nitride ceramic balls plus a super high speed PEEK inner cage to withstand the heat and stress of your engine. Proprietary internal tolerances have been incorporated into this ceramic bearing as well.
New generation PEEK polymer was chosen for the cages because of its superior combination of strength and flexibility, high operating temperatures, and high chemical and wear resistance. The design of the cage and material used are of paramount importance for the performance of the cage as well as for the operational reliability of the bearing itself.
Bearing cages are mechanically stressed by friction, strain and inertia. They may also be subjected to the chemical action of certain lubricants, lubricant additives or products of their ageing or organic solvents. The relative importance of these considerations can be affected by other operational parameters such as elevated temperatures, shock loads, vibrations or combinations of these and other conditions. The materials from which the bearing components are made determine to a large extent the performance and reliability of the rolling bearings. This why ACER Racing has used PEEK cages for our ceramic engine bearings.
PEEK cages have an excellent combination of strength and elasticity. The good sliding properties of the polymer on lubricated steel surfaces and the smoothness of the cage surfaces in contact with the rolling elements produce the lowest amount of
friction so that heat generation and wear in the bearing are at a minimum. The low density of the material means that the inertia of the cage is small contributing to greater speed. The excellent running properties of polymer cages under lubricant starvation conditions permit continued operation of the bearing for some time without risk of seizure and secondary damage.
Our PEEK bearing cages show no signs of aging by temperature and oil additives up to +200 °C (392°F).
