This FAG X-Life 32 BD series double-row angular contact ball bearing has gap seals, a 30-degree contact angle, a polyamide/nylon cage, a normal clearance rating, and a P6 precision rating. It supports radial loads, thrust loads in both directions, and combined loads, and occupies less axial space than a pair of single-row angular contact ball bearings mounted together. Because the two rows of rolling elements are mounted back-to-back, the bearing arrangement is relatively rigid and can accommodate tilting moments. The 32 BD series does not have filling slots and has a smaller cross section than the 33 BD series, making it suitable for smaller spaces, lighter loads, and higher speeds. This bearing is made of low-alloy, through-hardened chromium steel for durability and resistance to deformity under heavy loads. FAG X-life bearings are manufactured under FAG’s improved engineering processes, resulting in a rating life that is more than double that of the standard FAG angular contact ball bearing. The 30-degree contact angle of the balls in relation to the raceways gives the bearing a greater capacity for supporting thrust loads over bearings with a standard contact angle of zero degrees. Labyrinth-design gap seals made of nitrile butadiene rubber (NBR) on both sides of the bearing fasten to the outside ring, extend over the rolling elements, but do not make contact with the inside ring. The seals help keep out contaminants such as dirt and grime and also help to hold in a lubricant applied during manufacturing that lasts the lifetime of the bearing. This bearing has an injection-molded snap-type cage made of glass fiber reinforced polyamide 66 to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. This cage type can be used at operating temperatures up to 120 degrees C (250 degrees F). The bearing has a normal axial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. Additionally, the bearing has a dimensional and running accuracy to tolerance class P6 in accordance with Deutsches Institut für Normung (DIN) 620-2 for a higher level of precision than bearings manufactured to normal tolerances. ISO-rated ball bearings are manufactured to tight dimensional tolerances, making them useful in applications that require high accuracy, high rotational speeds, and increased operating efficiency. This angular contact ball bearing is for use in commercial and industrial applications including pumps and compressors, automotive drives, gearboxes, and printing machines, among others.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

FAG manufactures a variety of bearings that meet International Organization for Standardization (ISO) and Deutsches Institut für Normung (DIN) standards for quality assurance. The company, founded in 1883, is based in Schweinfurt, Germany.
