Shock sensitive loads

Xtra Heavy Duty Spring-

Loaded Kingpin Casters

Designed with greater load

capacity than our 40, 41, and 42

series, this series protects from

damaging shocks or unwanted

vibration and movement. Noise

levels are reduced through the

dampening effect of these casters.

Load Springs:

Maximum rated

capacity loads will deflect wheel

approximately 3/4”. Different

load springs permit wide variation

in ride “softness.” They can be

preloaded to obtain various degrees

of deflection

Swivel Top Plate:

AISI 1045 drop

forged steel for strength & reliability

Yoke Base:

AISI 1045 drop forged

steel with machined raceway

affords extreme wear and greater

capacity

Swivel Section:

Swivel load bearing

is 4” diameter deep grooved load

raceway with 1/2” steel balls and

the thrust race is 2-5/8” diameter

using 3/8” diameter steel balls

for maximum performance under

extreme loads

Legs:

3/8” steel plate, welded inside

and out to the yoke base to handle

side impacts

King Bolt:

1” diameter bolt and

nut heat-treated for maximum

performance

Axle:

3/4” diameter solid axle with

lock nut
