4 in Polyurethane Plate Mount Caster 506 lbs Load Industrial, Pkg Qty 10

Overview

This industrial plate mount caster is engineered for medium-duty material handling applications requiring a balance of high load capacity and floor protection. Designed to support substantial static loads, the unit features a robust polyurethane wheel that delivers smooth, quiet rolling performance on various indoor surfaces. The construction prioritizes durability and stability, making it an ideal solution for moving heavy equipment, racks, and carts in warehouses, manufacturing facilities, and distribution centers. By combining a high-strength mounting plate with a wear-resistant tread, this caster ensures reliable mobility while minimizing damage to sensitive flooring.

Key Features

Static load capacity rated up to 506 lbs per wheel Non-marking polyurethane tread protects delicate floor surfaces Superior noise reduction compared to metal or hard rubber wheels High abrasion resistance extends service life in demanding environments Precision ball bearings ensure smooth rolling with minimal effort Rigid plate mount design provides maximum stability and alignment Resistant to oils, greases, and common industrial chemicals

Specifications

Load Capacity: 506 lbs Wheel Diameter: 3.9 in Wheel Width: 2.0 in Overall Installation Height: 5.6 in Mounting Plate Dimensions: 4.5 x 4.0 in Wheel Material: Polyurethane Mount Type: Plate Mount Package Quantity: 10 units

Applications

Ideal for use on assembly line carts and workbenches Suitable for heavy-duty shelving units and storage racks Effective for transporting industrial machinery and generators Perfect for warehouse order picking trucks and platform dollies Recommended for food processing equipment where floor hygiene is critical Used in automotive repair shops for tool chests and parts carriers Applicable in hospital settings for silent movement of medical supply carts The polyurethane formulation used in this caster offers a unique combination of elasticity and toughness. Unlike traditional rubber wheels that may flatten under heavy loads or metal wheels that can dent floors, this material maintains its shape while absorbing minor shocks and vibrations. The 3.9-inch diameter provides an optimal rolling radius to overcome small debris and floor imperfections without requiring excessive pushing force. The mounting plate, measuring 4.5 by 4.0 inches, includes pre-drilled holes for straightforward installation onto standard equipment frames. With an overall height of 5.6 inches, the unit fits within standard clearance requirements for most industrial furniture and transport devices. This product is sold in packages of ten, ensuring sufficient inventory for equipping multi-wheel carts or replacing entire fleets of worn casters in large facilities.
