91 SERIES KINGPINLESS STYLE
20,000 LB. MAXIMUM CAPACITY

BENEFITS
The raceways of the 91 Series kingpinless style casters
are precision machined and then through hardened to
eliminate brinelling of the surface. This unique swivel
design allows the main caster bearing to operate in
shear where the load and thrust forces bear on the
7/8” diameter ball bearings. The 91 Series offers a
high strength swivel section that will easily swivel under
extreme loads.
FEATURES
Swivel Section: Constructed of hot forged C-1045
steel, the single ball race design features 7/8” diameter
load/thrust ball bearings in a 7” diameter precision
machined load raceway
Legs: 1/2” x 4” legs are formed and continuously
welded both inside and outside for greater strength.
Kingpin: Kingpinless style design.
Axle: 1-1/4”, Grade 5.
Lubrication: Pre-lubricated before shipping.
Wheels: 6” to 18” diameter wheels, 3” to 5” widths.
Finish: Gold dichromatic plating.
Standard: Shielded swivel to reduce dust and dirt
contamination.

APPLICATIONS
Specifi cally designed for severe applications, the 91
Series is ideal for die carts, tooling fi xtures, aircraft
engine stands, ground support equipment, aerospace
A-frame skin dollies, portable jigs, large work platforms,
mobile military equipment, aircraft maintenance stands
and production line delivery trailers.

Cast Iron Wheels Description: Phenolic Wheels Description:
These cast iron wheels are constructed of premium Class
30 gray iron for maximum load capacity and impact
strength. Each wheel is precision machined with rounded
edges to finished tolerances. All 1 ½” and 2” wide wheels
with ¾” roller bearings are supplied with ½” spanner
standard. The wheels feature heavy cross section castings
for heavy duty use, abrasion resistance and a long service
life. Built for high capacity applications, the cast iron
wheels can withstand extreme heat. Precision tapered
bearings are available to complement the characteristics
of the wheels.
A wide selection of phenolic resin wheels are available
in inventory. The wheels shown in the chart are
laminated phenolic. Standard black phenolic wheels
(30) feature macerated canvas duck compression
molded with premium phenolic resins to produce a
value/price relationship. High temperature phenolic
wheels (32) provide continuous service up to 425°
Fahrenheit and intermittently to 500° Fahrenheit. Lam-
inated phenolic wheels (35) feature a continuous wound
tread with a macerated canvas center. The wheels have
a 40% higher impact resistance and carry up to 25%
higher load than standard phenolic wheels. Phenolic
wheels are excellent for waste bins, platform trucks,
heavy material handling, autoclaves, baking ovens, and
high temperature bakery applications.
Bearings: Precision ball, delrin, straight roller and
   tapered.
Standard: All 1-1/2” and 2” wide wheels with 3/4”
   roller bearings are supplied with 1/2” spanner standard.
Polyurethane Wheels Description:
Made from Caster Concepts standard durometer 95A
polyurethane is easily identified by its maroon color.
Wheels are available in a standard profile thickness as
well as heavy duty (H.D.) 1 inch thick tires providing
increase maximum weight capacity. This material is
economical, provides lower rolling resistance than
rubber wheels and is floor protective. Sealed precision
ball bearings for the lowest rolling resistance for
ergonomic applications. Roller bearings when a low-
cost anti-friction bearing is required. Tapered bearings
for applications where towing and capacity are present.
Delrin bearings for wet applications where light loads
and infrequent movement is present; Oilite bearings for
low cost friction bearing where heat, moisture, infrequent
movement or lighter loads are part of the application.
70D Hard Polyurethane Wheels Description:
Processed in-house, elastomers provide flexibility in
material choice, hardness, and finished size. Caster
Concepts is adept at processing MDI polyesters,
and TDI polyesters and polyesters, in a wide range of
durometers from 50 durometer shore A to 70
durometer shore D scale.
Mold On Rubber Wheels Description:
Forged Steel Wheels Description:

Caster Concepts offers the highest quality domestic Mold
On Rubber wheels. Our mold-on rubber wheels consist
of a soft black, 70 durometer rubber tread permanently
bonded Class 30 gray iron centers. Mold on rubber
wheels provide excellent floor protection, a cushioned
and quiet ride for the product being transported, and they
absorb shock and vibration.
Bearings: Delrin, oilite, roller, precision ball, tapered.
Temperature: Maximum to 180° F
Durometer: 70 Durometer Shore A
Standard: All 1-1/2” and 2” width wheels with 3/4”
   roller bearings are supplied with 1/2” spanner bushing.

Forged steel wheels are hot forged from high carbon steel billets heated to 2,400 degrees then repeatedly hit by high tonnage forging hammers. This forging process enhances
the grain structure and increases the ductility and tensile
strength (64000 psi) of the wheel. The wheels are then
precision machined flat with rounded edged to finished
tolerances. Wheel material codes: forged steel (20);
heavy duty forged steel (21); ductile iron. Forged steel
wheels offer the greatest load capacity, impact strength
and roll ability of all caster wheels.
