BC Precision 608-ZZ Skateboard Bearing, 8x22x7, Shielded (Pack of 100)
Description
This 608-ZZ miniature radial ball bearing has double shields and a nylon cage,
and conforms to the ABEC 1 precision standard. This bearing has an 8 mm bore
diameter, a 22 mm outside diameter, and a 7 mm width. Its precision is rated
at ABEC 1 by the Annular Bearings Engineers Committee (ABEC), allowing higher
speeds and creating lower friction than less-precise ball bearings, and its
radial internal clearance is C3 for radial slack between the inner and outer
rings is greater than CN (normal) to compensate for thermal expansion. This
bearing is made of ASTM International 52100 steel and heat treated to increase
hardness for optimum wear resistance. Its deep ball grooves in both races
support high radial and axial loads, its straight bore fits conventional
cylindrical shafts, and its steel cage prevents the balls from coming into
contact with each other during use, reducing friction, vibration, and noise. A
no-contact steel shield on each side does not add friction or heat build-up
during operation and protects against rough contaminants. This ball bearing is
suitable for use in skate boarding, inline skating, and other skating
applications.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.
