81 SERIES KINGPINLESS STYLE
10,000 LB. MAXIMUM CAPACITY
BENEFITS
The 81 Series kingpinless style casters feature a unique single
ball race design. This design provides a high strength swivel
section that will swivel easily under extremely heavy loads.
FEATURES

Swivel Section: Constructed from drop forged C-1045 steel.
The swivel section features a large precision machined 4” single
ball bearing load/thrust raceway. The unique design of this
raceway actually places the 3/4” diameter load/thrust ball
bearings in shear, locking the swivel section together.
Legs: 3/8” x 4” formed and continuously welded both inside
and outside.
Kingpin: Kingpinless style design.
Axle: 1”, Grade 5 axle.
Lubrication: Pre-lubricated before shipping.
Wheels: 6” to 12” diameter roller bearing wheels have a
1-1/4” I.D. bearing and rotate on a 1-1/4” hardened and
ground steel spanner bushing. All tapered bearing wheels
have a 1” tapered bearing and rotate on a 1” axle.
Finish: Gold dichromatic plating.
Standard: Shielded swivel.
Swivel #81-10409-65-1LP
APPLICATIONS
Suitable for power drawn applications, fiberglass mold dollies,
aircraft wing and spar tooling, machinery, engine and paint line
dollies, body dolly carts, material carts, chassis rack carts,
towed trash gondolas, aircraft maintenance stands, production
line delivery trailers and automated guided vehicles

Cast Iron Wheels Description: Polyurethane 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.
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.
Forged Steel Wheels Description:
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.
Phenolic Resin Wheels Description:
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 T/R Compound Wheels Description:
This material produces a softer durometer wheel that
resists the accumulation of metal chips, sheet metal
screws, and foreign objects often found in manufacturing
facilities. The high rebound of this material provides
increased rollability in ergonomic in-plant applications,
and has become a favorite in production line delivery
systems across the country.
T/R Compound Ergonomic wheels, excellent for manual
pushed loads up to 1,500 pounds per dolly
Ductile Iron Wheels Description:
Ductile iron wheels feature many of the same charac-
teristics of cast iron; however, the ductile iron wheel has
higher tensile and yield strengths. Resists breaking or
chipping.
Mold On Rubber 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 trans-
ported, 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.

Hard Polyurethane (70D) 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 appli-
cations 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.
