Junction Blocks
Junction block surface mount systems are used to bring multiple lubrication points to a common, easily accessible location.
The junction blocks provide a means for coupling lubricant feed lines to bearings with lubrication fittings.
They are available in three basic design groups and may be mounted in multiple units to meet all application requirements.

Group I
Have 11/32" diameter mounting holes at 90° intervals,
for use with 5/16" diameter mounting bolts.
This permits horizontal or vertical positioning
of lubricant inlet passages.

Group II
Have 9/32" diameter mounting holes
for use with 1/4" diameter mounting bolts.
Mounting holes are perpendicular
to the inlet passages permiting
vertical positioning only.
