Bearing NF055AR0

The inch family of Reali-Slim thin section bearings includes seven
open series (Figure 1-2) and five sealed series (Figure 1-3), ranging
in bore diameters from 1.000 inch to 40.000 inches. Series
range from .187 x .187 inch to 1.000 x 1.000 inch in crosssection.
Open bearings are available from stock in three
configurations (Types A, C & X). Stock sealed bearings are
available in Types C & X only.
We can provide internal fit up, lubricants, separators and
other features to meet the most demanding specifications.
To obtain corrosion resistance consider using the Kaydon
stainless steel Reali-Slim or Endura-Slim series of bearings.
Endurakote plating provides corrosion protection equal to or
better than a full AISI 440C stainless steel bearing and can be
supplied with very quick delivery.
Additional product line variants include Reali-Slim MM metric
series bearings (Figure 1-4), Ultra-Slim bearings (Figure 1-1),
Reali-Slim TT series turntable bearings, BB metric ball bearings (all
found in Section 2), Bearings for Demanding Applications, and
KT thin section taper bearings (Section 6).
Within these families, you can generally choose between open
bearings for applications where bearings will not be exposed
to damaging particulates and sealed bearings for applications
where bearings need to be kept clean and well-lubricated.
To support various load scenarios, Reali-Slim bearings are
available in three basic types: radial contact (Type C), angular
contact (Type A), and four-point contact (Type X)—see pages
10 and 11 for explanations of each type—and in a variety of
sizes, or series (e.g., KA, KB, KC, etc.).
Reali-Slim bearings are available with various separator
options to space the rolling elements uniformly and prevent
contact between them. Separator types available include:
