Xtra Heavy Duty Spring-Loaded Casters
44 Series . Capacity to 1500
Designed with greater load capacity
than our 40 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.
Typical Applications
- Aircraft tripod jacks
- Portable medical equipment
- Computer equipment
- Shock sensitive loads
Features
- 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
- Neoprene sealed swivel section
specify NS42
- Lubrication: Zerk fitting in swivel
section and in wheel hub for
extended bearing life
- Alternate or custom caster
