special proximity collar using the collar setscrews, making
sure that the shaft does not protrude beyond the collar face.
Mounting the bearing to the shaft can sometimes lead to
slight runout of the collar face. Therefore, in order to assure
that the collar (D) is perpendicular to the shaft, it is
necessary to minimize the collar face runout to within .015".
1. Place proximity end cover (C) on housing mating surface
using RTV on the endcover as a sealant and tighten
mounting screws. Screw the proximity probe into the end
cover (C) until it bottoms on the raised portion of the
proximity collar.
2. Back the proximity probe 1

turn. This will provide the a
0.050" clearance gap between the proximity probe and
the setscrew collar.
3. Tighten the jam nut on the proximity probe up flush
against the endcover outer surface. Use 75 in-lb for jam
nut torque on AC probes (871 TM-B2N12-A2) and 25 in-
lb for jam nut torque on DC probes (871T-L2A12).
