PrecisionSteelBallBushing™bearingsareavailableinanopenversionforcontinuously
supported applications and a closed version for
end-supported applications. Extra precision
and adjustable versions are available on special request for end-supported
applications requiring higher precision and
repeatability. Precision Steel Ball Bushing™ bearing
products are also available factory installed in a self-aligning, malleable iron
pillow block minimizing installation
time and cost. The all-steel design
makes the Precision Steel Ball
Bushing™ bearing product line perfect for replacing plain bearings
in high temperature applications. Precision Steel Ball Bushing™ Bearings
This new patented self-aligning
linear bearing provides twice the load
carrying capacity or eight times
the travel life of the industry standard Thomson Super Ball Bushing™ bearing. This dramatic increase in load capacity
allows the use of less expensive drive
motors, linkages, gears and ball screws. The unique Super Smart design allows the bearing to maintain its diametrical fit up
when installed in housings that are soft
or slightly out-of-round. The new bearings are called “Smart” because their
universally self-aligning, double-track design
incorporates engineering concepts that literally
render old style conventional bearings obsolete. To minimize installation time and cost, the Super Smart Ball
Bushing™ bearing can beorderedfactory-installedinanindustrystandardsingleortwinpillowblock.Theclosed
type pillow block is used in end-supported applications
for spanning or bridging a gap. The open
style is used in continuously-supported applications when maximum rigidity

acting seals which keep out contaminants, retain
lubrication and maximize bearing life. Since
each Pillow Block is dimensionally interchangeable with the industry standard
Thomson Super Ball Bushing™ Pillow Block, system
performance improvements can be realized
immediately. Super
Smart Ball Bushing™ Bearings and Pillow Blocks Super Ball Bushing™ Bearings and Pillow Blocks Super Ball Bushing™ bearings offer three times the load
capacity or twenty seven times the life
of conventional linear bearings. Industry standard self-aligning Super Ball
Bushing™ bearings ease installation and minimize wear from minor bore misalignment.
Super Ball Bushing™ bearings can achieve speeds up to
10 ft/s and accelerations up to 450 ft/s2 without the derating
factors commonly found in linear guide products. With a coefficient of friction as low as .001, Super Ball Bushing™
bearings provide a quick, easy
replacement for high friction plain
bearings. The wear-resistant, engineered- polymer retainers and outer sleeves reduce inertia and noise
in critical, high-speed applications.
Thomson Super Ball Bushing™ bearings are also
available factory installed in single or
twin pillow blocks. Super Ball Bushing™ bearing pillow blocks are provided
with integral, double-acting seals that keep out contaminants and retain lubrication, maximiz-
ing system performance and life. Twin versions provide
up to twice the load capacity or eight
times the life of single versions, allowing the use of smaller and less
expensive drives, motors and ball screws.
When replacing v-ways and flat-ways, the Super Pillow Block’s low coefficient of friction reduces power
consumption and provides important design
economies.
