RK Series Casters

ROL KLEEN TEXTILE INDUSTRY CASTERS

RWM Caster’s Textile Industry Casters are designed to reduce the amount of thread buildup and reduce the time required to service casters used in this demanding application. These casters are used in all industrial caster applications where minimizing thread deposits wrapping around axles is beneficial. We are proud to say that these casters are Made in the USA!

FEATURES
Swivel SectionCold formed top plate, yoke and button are all heat treated to prevent brinelling, improve swivel action and increase service life. Load and thrust bearings are hardened and ground and rotate on hardened raceways. Top plate is 1/4” steel. Specially designed legs are forged for increased strength, ease of cleaning debris and continuously welded to yoke. All swivel sections are equipped with a lubrication fitting for field maintenance. RWM lubricates all swivel sections prior to shipment.
Kingpin5/8” diameter rivet hydraulically compressed to increase strength of swivel section on 1-1/2” wide wheels as compared to staking, 3/4” diameter rivet on 2” wide wheels
Kinpin Axle1/2” diameter bolt on 1-1/2” wide wheels. 5/8” diameter bolt on 2” wide wheels.
Axle1/2″ diameter drilled axle with lubrication fitting
FinishZinc plated to protect against corrosion
WheelsWheels are available with either straight roller bearings which rotate on a hardened and ground spanner or ball bearing for ease of rollability.
Thread GuardPrecision fitting full wheel thread guards to reduce string build-up around the wheel.

To order a rigid caster, change the “S” to “R” in the model number. For example: “RK-GTB-0415-R”. To order a rig only, omit the blue letters. For example: “RK-0415-R”.Dimensions shown are nominal. If precise dimensions are required, consult your RWM representative. For approximate weight of our rigid caster, deduct .9 pounds.
