Products Description
The 4 inch swivel caster is a versatile mobility solution engineered for industrial carts, equipment, furniture, and commercial applications. With a 100kg load capacity per caster and smooth 360° swivel action, this caster provides reliable support with stable rolling performance, superior shock absorption, and effortless maneuverability - essential for environments where equipment must be moved efficiently and quietly.
The impact on your daily operations: When industrial carts, equipment, and furniture need to be repositioned for maintenance, reconfiguration, or daily operation, reliable casters with smooth swiveling and durable wheels make the difference between efficient workflow and unnecessary downtime. The rubber on cast iron core wheel delivers exceptional shock absorption and vibration dampening - reducing noise levels, protecting sensitive equipment, and improving worker comfort. The cast iron core provides structural strength and heat dissipation for demanding applications, while the rubber tread delivers cushioned, floor-protective rolling. 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 Rubber on Cast Iron core wheel offers an optimal combination of shock absorption, durability, and floor protection. The cast iron core provides exceptional structural strength and heat dissipation for demanding applications, while the rubber tread delivers superior shock absorption, vibration dampening, and quiet, non-marking rolling that protects workshop and commercial floors. This solid rubber construction requires no maintenance and is immune to punctures. Optional wheel materials (PU, TPR, Nylon, PP) are available for applications with specific wear resistance, floor protection, or chemical resistance requirements.
Available with top plate mounting (103 × 80mm, bolt hole spacing 77/80 × 60mm) for secure attachment to carts, equipment, and furniture. Available in 4″ and 5″ diameters with multiple wheel material options and Roller Bearing as standard. The smooth 360° swivel action ensures effortless steering and maneuverability - making this 4 inch swivel caster the ideal choice for industrial carts, equipment, and furniture applications.

FAQ
Q1: What is the load capacity of this 4 inch swivel caster?
A: This 4 inch swivel caster has a load capacity of 100 kg per caster. For carts, equipment, or furniture with four casters, the total capacity is 400 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 are the advantages of the Rubber on Cast Iron core wheel construction?
A: The Rubber on Cast Iron core construction offers the best combination for applications requiring shock absorption and durability: Cast iron core - provides exceptional structural strength, heat dissipation, and durability under heavy loads; Rubber tread - delivers superior shock absorption, vibration dampening, quiet operation, and non-marking floor protection. This solid rubber construction requires no maintenance and is immune to punctures. It is specifically engineered for demanding applications where both cushioned performance and load capacity are essential.
Q3: Is this caster suitable for heavy duty applications?
A: Yes. This caster is designed for heavy duty applications with a 100kg load capacity per caster, a robust Rubber on Cast Iron core wheel, and a Roller Bearing for high-load performance. It is suitable for industrial carts, equipment, and furniture 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.
Q4: What wheel material options are available for this caster?
A: This caster series is available with five wheel material options: Rubber on Cast Iron - standard option offering superior shock absorption with structural strength; PU - excellent wear resistance and floor protection; TPR - quiet, non-marking operation; Nylon - superior impact resistance and durability; PP - lightweight and chemical-resistant. Choose based on your load, floor type, and application requirements.
Q5: What equipment is this 4 inch swivel caster suitable for?
A: This 4 inch swivel caster is suitable for: Industrial carts - workshop carts, service carts, and utility carts; Equipment - mobile equipment and machinery stands; Furniture - heavy furniture, worktables, and fixtures; Warehouse equipment - warehouse carts and trolleys; Commercial equipment - retail fixtures and display stands.
Q6: What is the mounting specification for this caster?
A: This caster uses top plate mounting with the following specifications: Top plate size - 103 × 80mm; Bolt hole spacing - 77 / 80 × 60mm; Bolt hole diameter - 10.5 × 9mm (slotted holes for adjustment flexibility). This mounting pattern ensures secure attachment for a wide range of carts, equipment, and furniture.
Q7: What is the advantage of the Roller Bearing?
A: The Roller Bearing uses cylindrical rollers to handle heavier radial loads - making it ideal for high-load applications where durability is the priority. Compared to ball bearings, roller bearings provide superior load capacity and are better suited for demanding industrial environments. This bearing type ensures reliable, long-lasting performance under continuous heavy use.
Q8: Is this caster suitable for office chair applications?
A: This caster is designed for industrial, commercial, and furniture applications with a 100kg load capacity. While it can be used on heavy furniture and equipment, it may be over-specified for standard office chairs. For office chair applications requiring mobility, we recommend our furniture caster series with optimized sizes and load capacities. Please contact our sales team for appropriate product recommendations based on your specific application.
Q9: What are the available sizes for this caster series?
A: This caster series is available in 4-inch and 5-inch diameters. The 4-inch option (featured here) offers a compact size with a 130mm load height - ideal for applications where space is limited. The 5-inch option provides better rolling efficiency over floor transitions and a higher load height.
Q10: Is this caster suitable for use on uneven floors?
A: Yes. The rubber on cast iron core wheel provides excellent shock absorption and performs well on moderately uneven surfaces. The rubber tread cushions impacts and smooths out floor imperfections. For significantly uneven surfaces or applications requiring maximum shock absorption, rubber remains the preferred choice over harder materials.
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 swivel caster?
A: Standard lead time is typically 20-45 days depending on order quantity, wheel material selection, and size specification. 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.
