2. For grease feed applications, the grease gland is assembled
with the “G” stamp in the 12 o' clock position. The grease
feeder (23) will mount in the grease gland at a 30 degree
angle from the horizontal. This is done to gain access to the
grease fitting located on the grease feeder. The lip seal (26)
mounted in the grease gland will be assembled as shown in
Figure 15.
3. For oiler feed applications, the grease gland is assembled
with the “O” stamp in the 12 o' clock position. The two
1 ⁄
8
" NPT connections on the grease gland will be located on
the horizontal, which is to ensure proper function of the
oiler. The lip seal (26) is to be mounted in the reverse or
opposite direction as shown in Figure 10.
4. The mounting of a grease feeder or oiler may require
additional pipe extensions and/or fittings that will be
provided from the factory as needed.
5. The grease feeder (23) will come with three springs (blue,
red and silver). The use of the different springs will be
varied depending on the operating temperature and the
lubricant (grease) to be used.
Grease Feeder Spring Size
Operating Temperature No. 1 Grease No. 2 Grease No. 3 Grease
-10ºF (-23ºC) to 40ºF (4ºC) SILVER RED —
-40ºF (-40ºC) to 110ºF (43ºC) SILVER SILVER RED
-110ºF (-79ºC) to 200ºF (93ºC) BLUE SILVER SILVER
Use SAE 30W oil for oiler application.
