Koyo 6000 series, 20 x 42 x 12
Available
This is the Koyo Deep Groove Ball Bearing, Metal Shielded (ZZ), 6000 Series.
This Koyo deep groove ball bearing (shielded, 6000 series) is built on the most popular rolling bearing type. Deep, uninterrupted raceway grooves in the inner and outer rings carry radial load and a certain degree of axial load in either direction, at high speed. It carries a metal shield on each side (ZZ type) and is pre-lubricated, so no greasing is needed.
The range has 24 sizes, with bores from 10 to 130mm, normal (CN) radial internal clearance and boundary dimensions to JIS B 1512. Koyo bearings are made by JTEKT Corporation.

Fitting and use
Fit the ring that has the interference fit first, and press only on that ring, never through the balls.
Do not relubricate: the bearing is pre-lubricated with an appropriate volume of grease. The standard type runs from -30°C to +110°C.
Where axial load is large, make the shaft shoulder and housing shoulder larger than usual.
Choosing the right option
Select by bore d first, then check the outside diameter D and width B in the specifications against your housing.
The basic dynamic load rating Cr relates to bearing life under rotating load, and the basic static load rating C0r to heavy or slow-turning duty. Compare the limiting speed for your size with the shaft speed. The speeds shown are the grease lubrication limits.
The ZZ shield is a non-contact type, with small friction torque, good high speed performance and good grease and dirt sealing. Koyo water resistance is economical, so choose a rubber sealed bearing where water is present.
Shielded and sealed bearings are designed for use with the inner ring rotating.
Also available from Koyo: the 6000 open range, the 6000 contact sealed range, the 6000 shielded C3 range.
