Products Description
The 4 inch caster wheel with stem is a versatile mobility solution engineered for shopping carts, industrial carts, equipment, and furniture. With a 120kg load capacity per caster and threaded stem mounting for secure attachment, this caster provides reliable support with stable rolling performance and effortless maneuverability - essential for environments where equipment must be moved efficiently and safely.
The impact on your daily operations: When shopping carts, industrial carts, and equipment need to be repositioned for loading, transport, or daily operation, reliable casters with smooth swiveling and durable wheels make the difference between efficient workflow and unnecessary downtime. The PU wheel delivers excellent floor protection, wear resistance, and low rolling resistance - allowing equipment to move smoothly with minimal effort. The threaded stem design with customization options ensures secure, vibration-resistant attachment across different equipment types. The smooth 360° swivel action ensures effortless steering in tight spaces and narrow aisles. The 100mm diameter with 32mm width provides good maneuverability and load distribution.
The PU (polyurethane) wheel offers an optimal balance of floor protection, wear resistance, and rolling efficiency. PU provides superior resistance to abrasion, grease, and oil - making it ideal for demanding retail, warehouse, and commercial environments. Unlike hard plastic wheels that can damage floors or rubber wheels that wear quickly, PU delivers long-lasting performance with smooth, quiet rolling. Optional wheel materials (TPR, Nylon, PP, Rubber) and bearing options (Axle Hole, Ball Bearing) are available for applications with specific floor protection, noise reduction, or performance requirements.
Available with threaded stem mounting (customizable) for secure, vibration-resistant attachment to shopping carts, industrial carts, equipment, and furniture. Available in 3″, 4″, 5″, and 6″ diameters with multiple wheel material and bearing options. The smooth 360° swivel action ensures effortless steering and maneuverability - making this 4 inch caster wheel with stem the ideal choice for shopping carts, industrial carts, and equipment applications.

FAQ
Q1: What is the load capacity of this 4 inch caster wheel with stem?
A: This 4 inch caster wheel has a load capacity of 120 kg per caster. For shopping carts, industrial carts, or equipment with four casters, the total capacity is 480 kg. However, please note that the effective load per caster should be calculated as Total Load ÷ 3 (allowing for uneven weight distribution) rather than Total Load ÷ 4.
Q2: What is the mounting specification for this caster?
A: This caster uses threaded stem mounting with customizable stem sizes - allowing flexible installation across different equipment types. Please contact our sales team with your required stem diameter, thread type, and length when ordering.
Q3: What are the advantages of PU wheels?
A: PU (Polyurethane) wheels offer: Floor protection - non-marking tread protects floors; Wear resistance - outlasts rubber and other soft materials; Oil and grease resistance - maintains integrity in various environments; Quiet operation - smooth, quiet rolling; High load capacity - supports heavy loads without deformation. These characteristics make PU the preferred choice for shopping carts, industrial carts, and equipment applications.
Q4: What wheel material options are available for this caster?
A: This caster series is available with five wheel material options: PU - standard option offering excellent floor protection, wear resistance, and oil/grease resistance; TPR - quiet, non-marking operation; Nylon - superior impact resistance and durability; PP - lightweight and chemical-resistant; Rubber - superior shock absorption for uneven surfaces. Choose based on your load, floor type, and application requirements.
Q5: What is the difference between Axle Hole and Ball Bearing options?
A: Axle Hole is a simple bearing design where the wheel rotates directly on the axle - cost-effective and suitable for light to moderate loads with occasional use. Ball Bearing uses precision ball bearings to provide smoother rolling with reduced friction - ideal for applications requiring frequent movement, smoother operation, and longer service life. Choose Axle Hole for cost-sensitive applications; choose Ball Bearing for enhanced performance and durability.
Q6: What equipment is this 4 inch caster wheel suitable for?
A: This 4 inch caster wheel is suitable for: Shopping carts - supermarket trolleys and retail carts; Industrial carts - workshop carts, service carts, and utility carts; Equipment - mobile equipment and machinery stands; Furniture - heavy furniture and worktables; Warehouse equipment - warehouse carts and trolleys.
Q7: Is this caster suitable for heavy duty applications?
A: Yes. This caster is designed for heavy duty applications with a 120kg load capacity per caster and a durable PU wheel. It is suitable for shopping carts, industrial carts, and equipment requiring reliable, durable mobility. For applications requiring even higher load capacities, we offer larger heavy-duty caster series - please contact our sales team for recommendations.
Q8: Is this a steel or metal caster?
A: This caster features a PU (polyurethane) wheel with a zinc-plated steel bracket - the bracket is made of steel for structural strength and durability. For applications requiring stainless steel casters or specific metal wheels, please contact our sales team for alternative configurations.
Q9: Is this a rubber caster?
A: This caster features a PU (polyurethane) wheel - it is not a rubber caster. For applications requiring rubber wheels or rubber-like performance, we recommend TPR (Thermoplastic Rubber) wheels which offer quiet, non-marking, floor-protective performance, or Rubber wheels for superior shock absorption. Both are available as optional wheel materials for this caster series. Please contact our sales team for more information.
Q10: What are the available sizes for this caster series?
A: This caster series is available in 3-inch, 4-inch, 5-inch, and 6-inch diameters. The 4-inch option (featured here) offers the best balance of rolling efficiency and load height (126mm) for most shopping cart and industrial applications. Smaller sizes are suitable for compact equipment; larger sizes provide better rolling efficiency over floor transitions.
Q11: What certifications does Xingteng hold?
A: Xingteng holds ISO 9001:2015 Quality Management certification, TUV Product Certification for multiple product series, and RoHS 2.0 environmental compliance. We are also a recognized AA-level "Contract-Honoring and Credit-Worthy Enterprise" in Zhejiang Province.
Q12: What is the typical lead time for this 4 inch caster wheel with stem?
A: Standard lead time is typically 20-45 days depending on order quantity, wheel material selection, bearing option, stem specifications, and size. For urgent requirements, please contact our sales team for expedited options. Large-volume orders may require additional lead time - we will confirm exact timing at the time of order placement.
