2 new main motor bearings

for all Rainbow Rexair vacuum D4C & D4C-SE Models               
                    + a motor parts diagram

These are for the main Rainbow motor, not the separate smaller motor that powers a brush roller.

2 double-sealed motor ball bearings (sealed on both sides),  pre-greased and sealed
for best protection in minimizing bearing corrosion from moisture and contaminants.  

If you enter a buy-it-now quantity of ‘1’, you will get 2 bearings.
     (We also sell this item in a qty of 3, in another listing)

        These will not fit D2 (metal canister) machines.


We include a D4C motor parts diagram/motor parts list with each purchase.
D4C and SE motors use the same motor parts diagram.
The diagram shows an exploded parts view of individual motor parts, and
cross-references to a list of Rainbow's motor part names and OEM numbers.

Boring additional technical bearing trivia, included because we get frequent questions
about NACHI brand bearings:
Rainbow does not make its motor bearings.  "NACHI", (the bearing brand name found in most Rainbows),
is a Japanese company.  NACHI brand bearings are currently manufactured in China.  
Nothing wrong with that, (quality-wise), as it's the grade/rating/specs of the bearing that are important,
and not the brand.  Our bearings come from American and/or Canadian bearing companies, and they too
are currently made in China or South Korea.  We sell and use bearings that are manufactured to the
same grade/rating performance specifications as the equivalent NACHI bearing found in many Rainbows.  
They perform equally as well.  Proper bearing size, grade, RPM/temperature, weight/load, and other
operating specifications for a bearing are important rating considerations in proper bearing rating
selection. . . not the brand.

Finally,
"R-5238" quality is better for replacing an R-1981 bearing because the R-5238 specification
double-sealed bearings are more effective in sealing out moisture and contaminants; ...
for that reason, we stopped selling or using the R-1981 specification over 10 years ago, and we use
these R-5238 quality bearings exclusively for any of the 3 motor bearing locations within
D4C and SE models.  ... they're only a few cents more for the extra (double nitrile seals) protection
(vs an R-1981), and, one no longer has to be concerned about which way a bearing's nitrile shield
should face during installation, because both sides of these double-sealed bearings are the same.
