Match#: 3309B.2RSR.TVH, 3309-CZZ, 3309-2NSL, 3309B.2RSR.TVH, 3309-2RST, 3309EE, W309-2RS
3309A.-2RS/TN9 This double-row angular contact bearing has two rubber seals to protect the bearing from any alien objects and corrosion of internal components and they are non-contacts toward inner ring. 3309B.2RSTR.TVH it has phenolic retainer, the retainer also referred to as the cage or separator, is used to separate and position the balls at equal intervals around the bearing raceways. The 3309-2RS is precision ABEC1 or P0 international standard accuracy, 3309-2NSE is capable of carrying axial load and rotation at the same time as medium duty double row angular contact ball bearing.
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 and Shielded bearings are lubricated with oil or grease in the bearing factory, while open 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, electric motors, CNC machinery, trucks, mining equipment, train, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
