4" TPR Plate Mount Caster 220 lbs Load Light Duty, Pkg Qty 20

Overview

This heavy-duty plate mount caster is engineered for light to medium-duty industrial material handling applications where stability and floor protection are paramount. Featuring a 4-inch thermoplastic rubber (TPR) wheel, this unit delivers exceptional load-bearing capacity while ensuring silent operation. The rigid, non-swivel design provides precise linear movement, making it the ideal choice for equipment that requires fixed-direction travel without lateral drift. Constructed for durability, the assembly supports a static load of 220 lbs per unit, offering reliable performance in warehouses, manufacturing facilities, and distribution centers.

Key Features

Silent TPR wheel construction prevents noise pollution in quiet work environments Non-marking tread protects sensitive epoxy, tile, and concrete flooring from scuffs Rigid fixed orientation ensures stable straight-line tracking for carts and machinery High static load capacity of 220 lbs supports substantial weight distributions Corrosion-resistant top plate suitable for varied industrial conditions Smooth rolling resistance reduces operator fatigue during manual pushing tasks

Specifications

Load Capacity: 220 lbs static load per caster Wheel Diameter: 3.9 inches Wheel Width: 1.26 inches Overall Height: 5.1 inches Mounting Plate Dimensions: 3.8 x 2.8 inches Wheel Material: Thermoplastic Rubber (TPR) Mounting Type: Plate Mount (Fixed/Rigid) Bearing Type: Precision ball bearing for smooth rotation Package Quantity: 20 units per pack

Applications

Ideal for assembly line conveyance systems requiring fixed paths Perfect for hospital gurneys, library carts, and office furniture where noise reduction is critical Suitable for food processing equipment due to non-marking and easy-to-clean wheel material Excellent for lightweight machinery skids and static storage racks Recommended for retail display units and inventory management carts Effective in clean room environments where floor contamination must be minimized The thermoplastic rubber formulation offers a superior balance between the resilience of rubber and the structural integrity of plastic. This composition allows the wheel to absorb minor shocks and vibrations, protecting both the transported load and the facility floor. The mounting plate features pre-drilled holes for straightforward installation using standard hardware, facilitating quick integration into existing fleets or new equipment builds. With an overall height of 5.1 inches, these casters provide adequate ground clearance for most indoor surfaces while maintaining a low center of gravity for enhanced safety. The fixed design eliminates the complexity of swivel mechanisms, reducing potential points of failure and maintenance requirements. Sold in bulk packages of twenty, this solution offers cost-effective scalability for large-scale operational upgrades or replacement programs.
