688-ZZ 688ZZ 688Z 688 ZZ Miniature Ball Bearing id 8 x od 16 x w 5mm

 

688-2RS/ 608-ZZ Bearings are made of Chrome Steel, pre-lubricated with grease and has rubber seals/ metal shields on both sides to protect the bearings from dust or any other types of possible contamination.

Single row deep groove ball bearings can support light-to-moderate axial loads in both directions as well as radial forces.

Due to their steady load capabilities, smooth and quiet rotation, high rigidity, low friction, standard accuracy, this high quality miniature ball bearings are particularly suitable for sports equipment (skateboards, roller skates, fishing reel, miniature slot car), household appliances, furniture, elevators, precise instruments, motorcycles, cars, bicycles, transportation equipment, mechanical equipment etc.

 

These ball bearings are made of high quality Chrome Steel/ Carbon Steel/ Stainless Steel and are pre-lubricated with grease from the factory and is available in ZZ (Metal Shields) and RS (Rubber Seal) configurations.

 

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.
