Capilube Bearings with solid lubricant oil

Maintenance Free bearing series
[ Capilube Bearings with solid lubricant oil ]
Machined type Needle Roller bearings
With a low sectional height, it can have large load ratings.
Machined outer ring has superior rigidity and can be fitted into light alloy housing.

Note ( 1 ) : This is the diameter of the cylinder used instead of the inner ring,
where the radial clearance becomes zero at least in one radial direction.
Design of shaft and housing
Capilube Machined type Needle Roller bearings does not
have inner ring so that the shaft can be used directly as the raceway
surfaces. Shaft and housing according to specification in
Table 3 are recommended.

Capilube Machined type Needle Roller bearing is a needle roller bearing that is prepacked
with thermosetting solid lubricant (Capilube) in the bearing space. As the bearing rotates,
the lubricating oil oozes out onto the raceway in proper quantity, keeping the lubrication
performance for a long period of time.

Note ( 1 ) : Care should be taken so that the radial internal clearance is not too
small.
Remark 1: This table applies to steel or cast iron housings. For lighter metal, a
tighter fit should be selected. For split housings, do not use a fit tighter
than J7.
