Koyo 6012C3 Deep Groove Ball Bearing, Open, 60 x 95 x 18 mm
Available
This is the Koyo Deep Groove Ball Bearing, Open, C3 Clearance, 6000 Series.
This Koyo deep groove ball bearing (open, 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 is supplied open, with no shields or seals, so lubrication and sealing come from the housing and the application.
The range has 21 sizes, with bores from 12 to 120 mm, C3 radial internal clearance and boundary dimensions to JIS B 1512. Koyo bearings are made by JTEKT Corporation.

Selecting the right option
Select by bore d first, then check the outside diameter D and width B in the table 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.
C3 is a radial internal clearance larger than normal. It is chosen where interference fits or a temperature difference between the rings take up clearance in service. Confirm the clearance class for your application.
Fitting and use
Fit the ring that has the interference fit first, and press only on that ring, never through the balls.
Lubricate to suit the application, and keep the housing clean, because there is no shield or seal on the bearing.
Where axial load is large, make the shaft shoulder and housing shoulder larger than usual.
