Low in frictional
torque and high in high-speed rotation performance
Space between fingers of the retainer protruding
into the spaces between the outer ring and adjacent
rollers
Arranged in two rows, filled with a lubricating
composition manufactured by solidifying a mixture of
an ultra-high molecular weight polyolefin and a
grease to reduce the number of contact portions of
the solid lubricating composition with the outer
ring and the rollers
Possible to considerably reduce torque and heat due
to sliding friction at the contact portions
With higher shock-resistant and lower rotating speed
features
Processing lubrication groove and lubrication hole
are provided
