Debris-Resistant Standard Plate Caster: 4 in Wheel Dia., 300 lb, Swivel Caster, C

Debris-resistant light-duty standard plate casters each have a thread guard that prevents thread and debris from getting into the caster's axle and damaging or contaminating it. This helps extend the life of the casters when they're used in dusty or dirty environments. They are suitable for transporting relatively light loads along smooth, flat surfaces in applications where they won't encounter shock loading, such as laundry rooms, textile factories, offices, retail stores, schools, and government buildings. The casters attach to the bottom of carts, dollies, tables, and similar equipment that will be moved manually at moderate speeds. Sometimes known as institutional plate casters, these light-duty standard plate casters have zinc-plated steel frames.

Standard plate casters have kingpins that securely join the casters' mounting plates to their frames. They are used in nearly every industry and are the most common type of caster used for general purpose applications. The casters' mounting plates install onto the bottom of machinery, carts, or other equipment, and the casters allow the equipment to roll to reduce effort when moving or repositioning it. These casters are available in swivel and rigid versions. The swivel casters can rotate 360°, allowing equipment to change directions while rolling. The rigid casters roll in a straight line. Two rigid plate casters will often be paired with two swivel casters to allow the equipment to both maneuver around curves and obstacles and maintain a straight course while rolling.
