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 configurations available
