Products Description
The 6 inch swivel caster is a versatile mobility solution engineered for shopping carts, industrial carts, equipment, and material handling applications. With a 140kg load capacity per caster and hollow kingpin mounting for flexible installation, this caster provides reliable support with smooth 360° swiveling, quiet operation, and floor-protective performance - 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 TPR wheel delivers quiet, non-marking rolling with excellent shock absorption - protecting floors and reducing noise in retail, warehouse, and commercial environments. The hollow kingpin mounting allows for flexible installation using bolts or rivets without protruding stems. The smooth 360° swivel action ensures effortless steering in tight spaces and narrow aisles. The 150mm diameter with 32mm width provides good maneuverability and load distribution.
The TPR (Thermoplastic Rubber) tread offers an optimal balance of quiet operation, floor protection, and rolling efficiency. TPR is widely recognized as one of the best materials for shopping cart and commercial applications - it is soft enough to protect floors and reduce noise, yet durable enough to withstand daily use. Unlike hard plastic wheels that can mark floors or create noise, TPR provides non-marking performance and a smooth rolling experience. Optional wheel materials (PU, Nylon, PP, Rubber) and bearing options (Axle Hole, Ball Bearing) are available for applications with specific wear resistance, load capacity, or performance requirements.
Available with hollow kingpin mounting (φ12 hole diameter) for flexible attachment using bolts, rivets, or custom fasteners. 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 6 inch swivel caster the ideal choice for shopping carts, industrial carts, and material handling applications.

FAQ
Q1: What is the load capacity of this 6 inch swivel caster?
A: This 6 inch swivel caster has a load capacity of 140 kg per caster. For shopping carts, industrial carts, or equipment with four casters, the total capacity is 560 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: Is this 6 inch swivel caster wheel available with a brake?
A: This standard model (316S3ZSX604-1E) is a swivel caster without brake. However, brake options are available upon request - including side brake and total lock brake configurations. If you require locking functionality for your shopping carts or equipment, please contact our sales team to specify your brake requirements.
Q3: What is hollow kingpin mounting and how does it work?
A: Hollow kingpin mounting (also known as stemless or bolt-hole mounting) uses a hole on the top of the caster for attachment. To mount, position the caster against the equipment and secure it with a bolt, rivet, or custom fastener through the φ12 hole. This design is particularly useful for shopping carts and custom applications where standard stem casters cannot connect - simply slide your bolt through the hollow kingpin center hole and secure it. It provides flexible installation without protruding stems.
Q4: Is this a rubber caster?
A: This caster features a TPR (Thermoplastic Rubber) wheel - TPR is a rubber-like material that offers quiet, non-marking, floor-protective performance. For applications requiring solid rubber wheels, we offer Rubber as an optional wheel material. Both TPR and Rubber provide excellent shock absorption and quiet operation. Please contact our sales team for more information on rubber wheel options.
Q5: Is this a metal caster?
A: This caster features a TPR (Thermoplastic Rubber) 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.
Q6: What wheel material options are available for this caster?
A: This caster series is available with five wheel material options: TPR - standard option offering quiet, non-marking operation with floor protection; PU - excellent wear resistance and floor protection; 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.
Q7: 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.
Q8: What equipment is this 6 inch swivel caster suitable for?
A: This 6 inch swivel caster 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; Material handling - platform trucks and transfer carts; Warehouse equipment - warehouse carts and trolleys.
Q9: 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 6-inch option (featured here) offers the best rolling efficiency over floor transitions with a 180mm load height. Smaller sizes are available for applications requiring lower load height or compact size.
Q10: What is the mounting specification for this caster?
A: This caster uses hollow kingpin (stemless) mounting with a φ12 hole diameter - accommodating bolts, rivets, or custom fasteners up to 12mm in diameter. This flexible mounting design allows you to use the fastener that best suits your specific application.
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 6 inch swivel caster?
A: Standard lead time is typically 20-45 days depending on order quantity, wheel material selection, bearing option, 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.
