Linear Ball Bearing Terms
– The amount of play or movement displayed when a bearing’s
inner ring is moved axially in relation to the outer ring.
– The load
under which a bearing can operate while rotating.
– A device
used to measure a bearing’s performance. Results are then used
for fault analysis.
– A device used
to separate the rolling elements of a bearing (also known as a retainer).
– The result of rolling
elements being forced onto inner or outer raceways, leaving indentations
in the raceway, which lead to premature bearing failure.
– Responsible for supporting
and moving the load. Carriers are commonly attached to the linear slide
with a bearing system.
– A wedge-shaped piece of
metal or wood designed to hold structural parts in place and/or provide
a bearing surface.
– The deteriorization
of bearing housings in grey
cast iron products.
– A special design
feature of a cage/retainer that allows grease to accumulate and then slowly
be fed to the rolling elements.
– The maximum amount
of weight that a bearing can withstand.

– A substance is used to lubricate the moving surface of a bearing,
protect against corrosion, conduct and transfer heat and keep contaminants
from entering.
– A term that refers
to the “fuzzy” appearance of the load-bearing surface of a
bearing, which is caused by contamination.
– The portion of the
bearing in which the ball or other part slides. Raceways provide the track
of confined movement for the bearing mechanism itself.
– The space
between the rolling elements and the races in an unmounted bearing, designed
so that the bearing has the necessary net clearance to operate.
– A device to stop the
ingress of contamination and the escape of lubrication.
– The long fasteners
used to hold the retainers together when riveted retainers are used in
a maximum bearing capacity.
– The ratio
of a material's strength to its cross-section.
– The study of friction,
lubrication and wear on two moving surfaces in contact.
– A statistical
analysis tool that is used to study bearing life and calculate the probability
of failure.
