4 Inch Caster Wheels Rubber Silent Castor - Heavy Duty Set of 4

In this review the 4 Inch Caster Wheels by ZDNEY are evaluated for workshop, cart, and furniture use; the bottom line is that these casters are a solid, quiet upgrade when you need durable, non-marking mobility. The reviewer found the primary reason to buy is the combination of a soft thermoplastic rubber tread and double-precision bearings, which together roll smoothly over gaps and debris while protecting floors. For anyone moving heavy carts or reconfiguring workshop furniture, these casters deliver reliable performance without loud noise or floor scuffing.

Key Features

• Wheel size: A 4 in diameter and 1.25 in width provide a balanced footprint that helps wheels roll over small obstacles with less resistance.
• Top plate fit: The 3-5/8 in x 2-3/8 in plate with 2-3/4 in x 1-3/4 in hole spacing fits common plate-mount applications for carts and workbenches.
• Load capacity: Rated for 400 lbs per caster, the set of four supports heavy-duty loads up to 1600 lbs for industrial and residential use.
• Soft thermoplastic tread: The non-marking gray thermoplastic rubber is softer than urethane and absorbs shock and vibration, protecting both equipment and floor finishes.
• Smooth bearings: Double-precision bearings extend service life and keep rolling quieter, which is useful in hospitals, labs, and food-service environments.
• Safety brake option: Four side brakes allow secure immobilization of carts and furniture when needed.

Who It's For

These casters are best for tradespeople, facility managers, and homeowners who need a quiet, non-marking solution for heavy carts, mobile workstations, display equipment, or furniture. They are especially suited to environments where floor protection and noise reduction matter, such as laboratories, food service areas, and offices.

Those who should look elsewhere include users needing ultra-high-speed swivel performance for precision applications or situations where a wider tire contact patch is required for very soft ground. If you require threaded-stem mounting rather than a plate, these plate casters will not be a fit.

Pros & Cons

Pros
