This heavy-duty rigid (fixed) industrial caster is designed for straight-line tracking, higher stability, and predictable handling under heavy loads. It pairs a durable fixed yoke with the most commonly spec’d polyurethane-on-aluminum wheel used across manufacturing, automotive, and plant environments for reduced push/pull effort, quiet rolling, and long service life.
Rigid casters are commonly used to provide directional stability. Many industrial carts use a 2 swivel + 2 rigid configuration to balance maneuverability and tracking.
Polyurethane-on-aluminum is a proven wheel configuration for facilities that need industrial capacity without the noise and floor harshness of steel wheels. The donut tread profile is designed to keep rolling consistently when floors are not perfectly clean.
Confirm your required top plate pattern, overall height, and load per caster before ordering. Choose bearing type based on duty cycle, speed, debris exposure, and floor condition. If you share your cart weight and floor type, we can recommend the best configuration.
It is the rated capacity per caster under proper load distribution and typical operating conditions. Total system capacity depends on how many casters are used and how evenly the load is carried.
