Oil Maintenance Schedule

Maintain oil level above bottom of center circle at all times

while unit is in operation. Drain, flush and refill with oil after 2

to 3 weeks of initial break-in operation. Since the satisfactory

operation of the bearing depends entirely on an oil film being

maintained between the shaft and the bearing liner surface, it is

recommended that an oil analysis be performed at these regular

intervals.

• Every 3 months for 24 hour/day service

• Every 6 months for 8 hour/day service

Acceptability of oil should be referred to the lubricant manufacturer.

If oil quality is acceptable then repeat this procedure in 3

month intervals. Visually check oil for contamination between

oil analysis checks. Oil service life depends upon several

factors such as ambient conditions, operating temperature and

frequency of bearing starts and stops. It is recommended that

the oil be changed at least once per year for unfiltered static

applications. Removing contaminants through the use of either

the OLF (Oil Level Filtration) Unit or a circulating oil system can

extend oil service life. Consult equipment manufacturer for more

information.

Oil film temperature in liner during operation should not exceed

180° F. If in doubt consult equipment manufacturer.

Options

Thermocouple or RTD. A thermocouple is used to sense the

temperature of the pillow block liner in the shaft area, and these

should be on every sleevoil bearing. If a pre-set thermal limit is

exceeded it can trigger a warning or, if desired, send a signal to

disconnect electrical power to the motor.

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

oil gauge holes have been provided as a standard means of

thermocouple mounting. Also finished with the pillow block is a

1/2" x 1/8" 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.

NOTE: 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 direction and safety procedures recommended by

manufacturer. Install wiring in accordance with national

electrical code and local codes.

Circulating Oil. The addition of a circulating oil inlet kit will allow

the bearing to be cooled and lubricated by circulating oil. Please

consult equipment manufacturer to determine if circulating oil is

required. The circulating oil inlet pipes are directed towards the

inspection holes in the liner.

Install oil supply lines to the 1/4" NPSF 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. The drain pipings

should be vented and must be of adequate size to remove the

oil at the specified flow rate. The housing drain must be directed

straight down into a return drain sloping away at 15° or greater

angle. The oiling system should have a means of filtering the oil

to remove any contaminating particles.

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. If the housing drain

is arranged to maintain the proper oil level and oil rings are

specifically requested, then oil rings may be used as a safety

measure or back-up oiling system without oil baffles.

Liters Approx.

End Closure Kits and Auxiliary Seal Kits are available and may

be added at any time without any machining to the pillow block.

Refer to the instructions packaged with the kits for installation
