Add On Options

  • When purchased with Wheel Brakes, please note they are not designed to hold on inclines.
  • Total Lock Brake locks Swivel and Wheel.
  • Swivel Lock converts a swivel caster into a rigid caster for direct line travel.
  • Swivel Locks lock ONLY swivel, not the wheel.

Stainless Steel Caster Model 9 Features:

img Deduct 1 lb. for weight of rigid caster.
img Swivel Radius Information: The Total Locking Option ( TL ) changes the Swivel Radius of the caster to the following; 4″, 5″ and 6″ diameter wheels = 6 1/2″ Swivel Radius 8″ diameter wheel = 7 1/2″ Swivel Radius
img Maximum Capacity under ideal conditions. If your application exceeds 40 minutes at the maximum temperature rating for these wheels contact us at 800-501-3808 for a recommendation.
img Swivel Construction – cold forged top plate and yoke base from 1/4″ Stainless Steel.
img Legs – 1/4″ thick, welded inside and out.
img Axle – 1/2” diameter hollow bolt with lock nut.
img Standard Wheel Bearing: D= Delrin Bearings, P= Plain Bore, SPS= Stainless Precision Sealed Ball Bearings, SSR= Stainless Steel Roller Bearing
img Grease Fittings – for swivel and wheel bearings.

Mounting Plate – 4″ x 4 1/2″

Stainless Steel Caster Model 9 with Wheels

Stainless Steel Caster Model 9 Instructions:

You should never select on the basis of load capacity alone. Capacity ratings do not take into account the effort required to manually move a load. Capacity ratings are based on manual operation under ideal conditions. If these casters are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application. If a human being has to move the weight, select the largest practical wheel diameter. If a caster failure occurs it is almost always because of misuse or abuse. It has been very rare that a product failed because of faulty material or poor workmanship. The following are examples of things that we do NOT want you to do:

1. Dragging the wheel sideways.
2. Shock or Impact caused by dropping the load instead of setting it down on the castered equipment.
3. Improper Installation such as:
A. Rigid casters not installed parallel to one another.
B. Swivel casters not installed parallel to the floor.
C. Using less than 4 bolts to attach the mounting plate.
D. Distortion of the swivel bearing when attaching the mounting plate due to welding improperly.
4. Exceeding the rated capacity of the wheel or caster.
5. Exceeding a rolling speed of 3 MPH.
6. The build up of heat caused by continuous operation causing tire separation.

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
