Special Duty
The standard housing material for Special Duty mounted
bearings is ASTM A48 Class 30 Iron having a minimum tensile
strength of 30,000 psi. The outer housings for the pillow
blocks and flange bearings are of split construction for ease
of replacement of the completely assembled, adjusted and
lubricated inner units. The housings for the D, S-1 and B-1 units
are of solid one piece construction. Pillow blocks and flange
bearings are available in both expansion and non expansion
types.
Special Duty mounted bearings have duplex tapered roller
mounted to the shaft with a tapered adaptor sleeve extending
thru the complete length of the pillow block. The tapered roller
bearings used in the Special Duty mounted bearings all have
case carburized inner races (cone), outer races (cup) and rollers.
A single adapter nut is used on sizes thru 3-1/2” with two
adaptor nuts being used on the larger sizes. The nut at the large
end of the taper can be used to remove the bearing from the
shaft.
Special Duty mounted bearings have two piston ring seals
running in grooves in the seal ring carriers at each end of the
units to seal the bearings both on and off the shaft. Sizes thru
3-1/2” use a grooved seal ring carrier at one end and grooved
adaptor at the opposite end for carrying the piston ring seals.
Larger sizes have grooved adaptor nuts to carry the piston ring
seals.
SPECIAL DUTY (Hinged Cap Type)
The standard housing material for Special Duty hinged cap
bearings is ASTM A48 Class 30 Iron having a minimum tensile
strength of 30,000 psi. The housing is equipped with a brass
hand wheel for ease of removal of the S-1 unit from the pillow
block housing. Hinged cap pillow blocks are available in both
expansion and non-expansion types.
Hinged cap pillow blocks and units are mounted to the shaft
with a tapered adapter sleeve extending completely thru the
unit. The tapered adapter sleeve is equipped with micro mount
removal screws for ease of demounting the bearing from the
shaft.
The hinged cap pillow blocks are arranged for relubrication
from the end of the pillow block rather than from the top of the
pillow block. Besides the features specified above the hinged
cap pillow blocks have many other features in common with the
special duty mounted bearings.
TRACTION WHEEL
The traction wheel is to be equipped with a ductile iron (ASTM
536 grade 65-45-10) hub, having indirect mounted tapered roller
bearings mounted to ASTI 1018 shafting secured in a support
and having drops of 7-3/16”, 8” and 10”. Combination labyrinth
and dynaface seals shall be used.
