3x8 Bearing 3x8x4 Metal Bearing 693ZZ for Yo-Yo/ Yoyo Balls
These ball bearings are made of high quality Chrome Steel and are pre-lubricated with grease from the factory and is available in ZZ (Metal Shields) and RS (Rubber Seal) configurations.
The 693-ZZ is a 3 mm bore ball bearing that is found in many applications. The 693-ZZ bearing has two non-contact metal shields, one on each side of the ball bearing. If your application requires a 693 ball bearing with only one shield you can simply remove one of the shields. This 3 mm bore ball bearing is a high quality product and can operate efficiently in many demanding applications.
The 693-2RS 3x8x4-millimeter sealed miniature ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. The rubber seals on both sides of the bearing keep lubricant in and contaminants out, and it comes pre-lubricated from the manufacturer so that no additional lubrication is required. This deep-groove sealed miniature ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others.
Quality Benefits Include:
·Textured Buna N Nitrile seals
·Wide temperature range Chevron SRI-2 (-20° to +350°F) lubrication
·Passes Noise Vibration Standard for low noise
·Designed for many types of applications
·Matched ABMA grade precision balls for roundness
·Finely honed super finished raceways for long life and low noise
·Meet or exceed ABEC 1 tolerances for high quality level
·Bulk packaged
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.
