Check construction drawing for proper coolant flow rate. If not

given, use flow rate shown in the following table as a general

starting point for proper cooling. Lower coolant inlet temperature

and (or) lower ambient temperature require less flow. If the

coolant inlet temperature exceeds 90ºF additional coolant will be

required. The interior pressure of the liner should never exceed

120 psi. Unless specially ordered. Anti-freeze type additives may

be used with the water in cold operating environments, otherwise

purge all coolant from the liner by blowing out with compressed

air or steam anytime bearing coolant is subject to freezing.

Any questions on installation, maintenance, or arrangement of

coolant connection inlets and outlets should be referred to the

equipment manufacturer

CAUTION: The fluid or air pressure should never exceed 120

p.s.i.

OPTIONS

Thermocouple or RTD. A thermocouple is used to sense the

operating temperature in the shaft area. If a pre-set thermal limit

is exceeded it can trigger a warning or shut-down. There is no

substitute for proper condition monitoring. All Sleevoil bearings

should contain either an RTD or Thermocouple.

temperatures are not an accurate display of internal bearing

temperature.

Two 1/2-14 N.P.S.F. threaded holes on the side opposite the

"X" marking have been provided as a standard means of

thermocouple mounting. Also furnished with the pillow block is

a 1/2"x1/8" adapter bushing to allow adaption of thermocouples

from several manufacturers. Spring loaded thermocouples

are recommended for positive contact.

Install the thermocouple in the location shown on the

construction drawing. Make certain the probe extends into

the liner thermocouple hole. For non-expansion bearing, the

thermocouple should be located in the hole nearest to the

end carrying the thrust load. When the direction of the thrust

load is not known, two thermocouples are recommended. For

expansion bearings, the thermocouple can be located at either

end. Depending on thermocouple and bearing size it may be

necessary to employ a system of pipe nipples and couplings to

achieve proper probe penetration and housing clearance. Use

sealant on all threaded connections including thermocouple

mounting thread. Apply sealant to the pipe plug furnished and

install it in the other hole.

Thermostat and Immersion Heater. An immersion heater is

used to maintain a minimum oil temperature in the pillow block.

The thermostat, used in conjunction with the heater, monitors

oil temperature in the pillow block and regulates the immersion

heater.

If the pillow block has been machined for a heater and thermostat

the threaded mounting holes are usually located in the end face

of the housing base. Install heater and thermostat using sealant

on all threaded connections to prevent oil leakage.

CAUTION: Before filling and draining oil from pillow block

be sure heater is off or it will overheat when not submerged

in oil.

WARNING: When installing heater and thermoswitch,

follow directions and safety procedures recommended by

manufacturer. Install wiring in accordance with National

Electric Code and local codes.

Circulating Oil. If using circulating oil, a circulating oil inlet kit

must be used. Circulating oil inlet kits make use of the existing

inspection cover ports on top of the bearing.

inspection ports and use the supplied screws to attach the clear

Housing

plate to the bearing. Insert the 1/4" NPT threaded pipe nipples

into the clear plates. Pipes extend through the clear plates and

are directed toward the inspection holes in the liner. The standard

drain arrangements are shown. Consult manufacturers drawing

for exact dimensions and location of drain(s).

Install oil supply lines to the 1/4" N.P.T. external (male) threaded

inlets so that each inlet will receive an equal amount of oil. Make

sure that the oil flows from the pipes directly into the inspection

holes. Drain piping should be vented and of adequate size to

drain oil from the bearing at the specified flow rate. The housing

drain must be directed straight down into a return drain sloping

away at a 15 degree or greater angle from the horizontal. The

oiling system must have a means of filtering the oil to remove

any contaminating particles. A 25 micron filter or better is

recommended.

When baffles are installed in oil ring grooves of upper liner, oil

rings cannot be used and should be discarded. Bend baffle so

that free end rests on lower liner joint. Since the housing drain is

arranged to maintain the proper oil level, then oil rings may be

used as a safety measure of back-up oiling system without oil

baffles.
