Using only four buttons and the well proven laser alignment techniques, the SKF Shaft Alignment Tool TMEA 1, makes accurate machine alignment operation simpler and quicker than with traditional m ethods and equipment.

Comparison of Physical Properties of Typical Pillow Block Housing Material SKF pillow blocks are usually made of cast iron and are mainly intended for grea se lubricated ball chumacerzs roller bearings.
For a shaft diameter of 50mm, and approximately 1 for shaft diameter of mm. The housing cap is fitted, being careful not to damage the O-rings on the O.
Same features, cast in steel.
The level of oil should be about the center of the lowest ball or roller when the bearing is stationary. Where there is a risk of the grease becoming contaminated, the relubrication intervals should be reduced. Do not allow the V-ring seal lip to pass through the sheet metal washer. SKF BeltAlign attaches simply and securely to the pulley; two V-guides grip the groove while bar magnets hold the unit firmly in place.
Any bearing deprived of correct lubrication will fail well within its predicted lifespan. Do not apply lockwasher. To recognize A-design, cap of Series: The housing base is checked for alignment, ensuring that the housing is within acceptable limits, and the mounting bolts are then slightly tightened. The bearing positioned in the centre of the bearing seat in the pillow block housing will ensure proper lubrication as well as shaft expansion and contraction. The simplest way to mount the cords is to use a screwdriver blade while rotating the shaft by hand.
Never roll the rollers over the feelers as the wrong is to be placed in the position requiring the least tightening to value will be obtained. The housing cap is fitted and the cap bolts tightened to the recommended torque, see table on Pages 26 through Turn the nut with a hook spanner according to the illustration.
Hermetic sealing prevents ingress of dirt or foreign matter. If a contact rubbing seal is selected, care must be taken with regard to the surface finish of the shaft.
Consult SKF for more detail. The rubber O-section cords are placed in the grooves in the housing cap.
Finally the housing mounting bolts are tightened to the support. Pillow block split design inch overall dimension can be used for metric or inch shafting. The bearing must be seated firmly against the shaft shoulder. This ensures an accurate clearance measurement, avoids the mess in trying to handle a greasy bearing, and decreases the possibility of additional contamination being introduced into the bearing.
To recognize N-design, the block has 4 hex.
Pillow block housings of series SNL 5 and SNL 6 are available with split felt seals consisting of oiled felt incorporated in halves of a light alloy ring, the seal halves are fitted into the housing grooves, the O-section cords provide an effective seal between the housing hub bore and the outside diameter of the seal inserts.
Lubrication through center fitting for W33 Non W33 If grease is used as a lubricant, at installation of bearing the lubricant must be worked in between the rolling elements. For greasing quantities, refer to Page The simplest way to move the V-rings is to use a screwdriver blade while rotating the shaft by hand. A verysmall movement of the nut will usually align a tab with a slot.
The recommended intial grease charge is one-third to one-half the volume of the free space in th e pillow block, and the empty space between rolling elements and cage filled with grease buttered. The mounting bolts are tightened to the support.

SSNHD Standard SAF pillow blocks are made of cast iron with either self-aligning double row ball bearings for normal loads or self-aligning spherical roller bearings for heavy loads. To recognize A-design, cap of block is held down with 2 hex.

Slide one labyrinth seal, consisting of labyrinth flinger, with prongs pointed towards bearing location and labyrinth insert with O-ring installed on its O.
Poor machine alignment generates additional loads and vibration, causing premature damage to bearings, seals and couplings. High accuracy but simple cwtalogo operate The TMEA 1 alignment tool uses two measuring units, both provided with a laser d iode and a positioning detector.
The bearing is mounted on cstalogo shaft directly or on an adapter sleeve and filled with grease. The housing cap is filled and the cap bolts tightened to the recommended torque, see Table on Pages 26 through The shaft, complete with bearing assembly, is placed in the lower half of the housing. Apply a coat of light oil to the shaft and bearing bore. The second labyrinth seal is placed on the shaft following instruction as described above under 2, except reverse sequence.
And at a very competitive price!
For held unit, fixing rings are placed in position. If the bearing is a C3 fit, the outer ring will swivel freely. Afte r a number of such relubrications, the housing should be opened and the used grease removed before fresh grease is added.
