4" Conductive Rubber Threaded Stem Caster, 253 lbs Load, 6.3 in Height, Pkg Qty 20

Overview

This heavy-duty threaded stem caster is engineered specifically for static-sensitive industrial environments where equipment mobility and electrostatic discharge control are critical. Featuring a 4-inch conductive rubber wheel, this unit provides reliable grounding to protect sensitive electronic components from damage during transport. The robust construction supports substantial weight loads while ensuring smooth, quiet operation that preserves floor integrity. With an overall mounting height of 6.3 inches, it offers an optimal balance between clearance and stability for various material handling carts, assembly line fixtures, and cleanroom equipment.

Key Features

Conductive rubber wheel composition effectively dissipates static electricity to prevent ESD damage Threaded stem design ensures a secure, vibration-resistant connection to equipment frames High load capacity of 253 lbs per caster supports heavy industrial machinery and loaded carts Smooth-rolling performance minimizes floor marking and reduces operator pushing effort Durable rubber tread provides excellent shock absorption and noise reduction Ideal for use in electronics manufacturing, cleanrooms, and static-controlled storage areas

Specifications

Load Capacity: 253 lbs per unit Wheel Diameter: 4 in Overall Height: 6.3 in Wheel Material: Conductive Rubber Stem Type: Threaded Stem Package Quantity: 20 units per pack Application Environment: Static-sensitive and cleanroom facilities

Applications

Electronics assembly lines requiring strict ESD protection protocols Cleanroom environments in semiconductor and pharmaceutical manufacturing Mobile workstations and testing racks for sensitive instrumentation Hospitality and healthcare equipment carts needing quiet, floor-safe mobility Warehouse order picking carts operating in static-controlled zones Laboratory equipment transport where grounding and stability are paramount This product delivers a specialized solution for facilities where standard casters pose a risk to electronic inventory or process integrity. The conductive properties of the wheel material create a continuous path to ground when paired with appropriate flooring and mounting hardware, safely neutralizing built-up static charges. The threaded stem installation method allows for quick replacement and firm attachment, preventing accidental detachment under dynamic loading conditions. Whether deployed on lightweight service carts or heavier production fixtures, these casters maintain consistent performance over extended operational cycles. The packaging configuration of 20 units per pack facilitates bulk procurement for large-scale facility upgrades or fleet replacements, ensuring uniformity across all mobile assets. By combining high load-bearing capabilities with essential static control features, this caster series supports efficient material flow without compromising product safety or equipment longevity.
