608VV Mini Ball Bearing

Key Features

608VV is a Miniature Ball Bearing designed with non-contact seals and is pre-lubricated with grease allowing it to be ready for use upon delivery. 608VV Non-Contact Seals are made to seal the bearing without making physical contact between the stationionary elements and moving elements. As a Result, 608VV produces less friction which can prevent overheating and other potential issues. While non-contact seals do not touch the inner ring, they do feature a thin lip that rests adjacent to it, locking the seals in place. Our 600 Series Bearings have Larger OD which assists in high speed & larger load application.

What are Ball Bearings?

A ball bearing is a type of rolling-element bearing that uses roller balls to separate two “races,” or bearing rings. The combination of the roller balls and bearing rings help to reduce surface contact and rotational friction across moving planes to accommodate axial loads.

Ball bearings help to facilitate motion by distributing loads and reducing friction for applications that have a high-speed requirement, ultimately aiding in extending the working life of your equipment.

What are Rolling-Element Bearings?

Rolling-element bearings, commonly called rolling bearings, are bearings that carry a load by utilizing “rolling elements” between two concentric, grooved rings called races. The motion of the bearing races allows for the rolling elements to move with very little resistance and with little slide variance.

Some common types of rolling elements include ball, cylindrical, spherical, barrel, needle, spindle, or tapered.

What is the Difference Between Open, Shielded, and Sealed Rolling Bearings? 

The main difference between open and sealed/ shielded bearings is the application of lubrication. The main difference between sealed and shielded bearings is the presence of a protective enclosure.

  • Sealed and shielded bearings are both lubricated with oil or grease in the bearing factory. However, a rubber sealed bearing protects the bearing by using a seal that contacts the inner and outer race. This provides superior protection at the cost of operating speed and temperature.
  • Open bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use.
  • Shielded rolling bearings contain an enclosure that helps to protect the working parts of the bearing from environmental debris that may be introduced and would otherwise reduce the ball bearing speed and lifespan. This metal shield is stamped onto the bearing and only contacts the outer ring, this allows for protection without sacrificing operating speed or temperature.

Saved me a lot of money.
I highly recommend this bearing. Less than $15 for 2 bearing shipped saved me a lot of money fixing this Radon fan.

Good Bearing - replaces NSK 122 608v1
Needed this bearing for an Electrolux vacuum motor.
Worked just as predicted.
