INSTALLATION

USN 500 & 600 Series Adapter Mount

Apply a coating of light oil or other rust inhibitor to the adapter

area of the shaft.

Measure the internal clearance of the bearing before

mounting. Place the bearing in an upright position as shown

in Figure 1. Seat the inner ring and roller elements by pressing

down firmly on the inner ring bore while rotating the inner ring

a few times. Position the roller assemblies so that a roller is

at the top most position on either side. For bore sizes above

135 mm only, press these top rollers inward ensuring contact

with the center guide ring. Using a feeler gauge measure the

clearance for each side by inserting as far as possible and

sliding over top of roller (Figure 1). Write down the measured

clearance for use in Step 3e.

Note: Do not rotate bearing when moving feeler between

roller and outer ring.

Install the bearing parts in the following sequence. (Refer to

parts drawing)

V-ring Seal—Slide one of the V-ring seals onto the shaft,

making sure lip is toward the bearing.

Note: Do not install V-ring seal on seal ring until

housing cap has been set in place and tightened.

Seal Ring—Install a seal ring on shaft with largest O.D.

toward bearing.

Adapter Sleeve—Slide adapter sleeve onto the shaft,

threaded end outboard to the approximate location of the

bearing. Apply light coating of oil to sleeve O.D. Do Not

Use Grease.

Bearing—Make sure that the internal clearance has

been written down. Install bearing on adapter sleeve,

large end of tapered bore first. Locate bearing in proper

position on shaft.

Figure 1 - Internal Clearance

Lockwasher and Locknut—Install the lockwasher on

the adapter sleeve with inner prong located in the slot

of the sleeve and pointing towards the bearing. Install

locknut, chamfered face toward bearing as

Tighten locknut using a spanner wrench and hammer

until clearance noted in Step 2 is reduced by amount

shown in Table 1. During this step shaft should be

supported so all weight is off the bearing.

Now find a lockwasher tab that aligns with a locknut slot and

bend tab into slot. If slot is past tab then tighten, not loosen,

locknut to meet a washer tab.

Steps f and g are not necessary if pillow block housing is a cast

closed end style.

Seal Ring—Install second seal ring with large O.D.

toward locknut.

V-ring Seal—Slide second V-ring seal onto the shaft,

making certain lip is toward bearing. Do not install V-ring

seal on seal ring until housing cap has been set in place

and tightened. For assistance in installing seals, use

instructions supplied with the seals.

Remove any paint, dirt or burrs from the mating surfaces of

the housing halves. Thoroughly clean seal grooves on both

sides. Set lower half of housing on base and apply oil to the

bearing seats.

Apply grease to the bearing and seal rings. The lubricant

should be smeared between the rolling elements (see Grease

Lubrication section). This step and the first sentence of Step

9 do not apply for oil-lubricated bearings.

Place shaft with bearing into lower half while carefully guiding

the seal rings into the housing grooves.

Bolt lower half of the non-expansion bearing to the base.

Move shaft endwise so that spacer ring can be inserted as

shown on Figure 4. Center all other bearings on same shaft in

their housing seats. Note: Only one bearing per shaft is non-

expansion, other bearings should be expansion.

When closed end is required and the block is not a cast

closed, an optional end plug may be fit into the center seal

ring groove of the housing. Shaft extension should not be

beyond adapter end to ensure no rubbing with end plug or

housing on cast closed end.

Grease the bearing seal grooves in the housing cap and place

over the bearing after wiping the mating surfaces (does not

apply for oil-lubricated bearings). The two dowel pins will align

the cap with the lower housing half. Note: Each cap must

be matched with its mating lower half, as these parts are not

interchangeable. Cap and base have serial number stamped

at joint. The serial numbers should line up for proper match. If

the blocks are mounted other than in the horizontal position, a

sealer must be applied at the cap and base mating surfaces.

10. Tighten cap bolts to the recommended torque shown on

Table 2.

11. Assure that there is running clearance at seal rings, then

install V-ring onto the seal rings as shown on Figure 4. Coat

V-ring seal with grease to protect against ozone attack.

12. Misalignment of plummer blocks must not exceed ±1/2º (one-

half degree).
