Caster performance emerges from wheel, bearing, fork, mounting, load and floor—not from one catalog number.

04Caster offset
Rolling resistance is not a single material value.
It is the measured response of the wheel, caster, load, alignment and floor at a defined operating condition.
Load
The complete load path changes wheel and bearing behavior.
Floor
Joints, debris, texture and thresholds can dominate the route.
Alignment
Swivel orientation and wheel layout affect actual push force.
Installed caster load is an equipment problem.
Use a conservative support assumption for preliminary sizing, then validate the real frame and route.
Total mass
Include equipment, payload, accessories and foreseeable loading.
Center of gravity
Check how the load shifts across the installed caster positions.
Frame stiffness
Do not assume every caster carries an equal reaction.
Floor condition
Allow for uneven support, thresholds and dynamic transfer.

Questions, principles and design decisions
01
definition
↗02What Is Caster Offset?
Caster offset is the horizontal distance between the swivel axis and the wheel contact or axle reference that creates trailing behavior.
comparison
↗03Dynamic Load vs Static Load for Casters
Static load describes supported weight at rest, while dynamic load addresses the more demanding conditions created during movement.

↗04Floor Condition and Caster Selection
Floor hardness, joints, debris, slope and surface condition influence wheel size, tread, push force, noise and durability.
calculation
↗05How to Calculate Caster Load Capacity
Calculate total system mass, nominal load per caster and a conservative design load that reflects uneven support and operating conditions.
definition
↗06What Is Rolling Resistance in a Caster System?
Rolling resistance is the force that opposes steady wheel motion because the wheel, floor and bearings deform or dissipate energy.
explanation
↗07Starting Force vs Rolling Force
Starting force is the peak effort needed to initiate motion, while rolling force describes effort after stable movement begins.
explanation
↗How Wheel Diameter Affects Rolling Resistance
Larger wheels generally cross small obstacles more easily, but wheel material, bearing, load and floor still control the actual force.
