Products Description
The 3 inch heavy duty caster is a versatile mobility solution engineered for industrial carts, material handling equipment, workstations, and light machinery. With an 80kg load capacity per caster and smooth 360° swivel action, this heavy duty swivel caster provides reliable support with stable rolling performance and effortless maneuverability - essential for industrial environments where equipment must be moved efficiently and safely.
The impact on your daily operations: When industrial carts, equipment, and workstations 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 PU wheel delivers excellent floor protection, wear resistance, and low rolling resistance - allowing equipment to move smoothly with minimal effort. The smooth 360° swivel action ensures effortless steering in tight spaces and narrow aisles. The 75mm diameter with 32mm width provides good maneuverability and load distribution for light to medium industrial applications.
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 workshop and warehouse 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 top plate mounting for secure attachment to carts, equipment, and workstations. 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 3 inch heavy duty caster the ideal choice for industrial carts, material handling equipment, and light machinery applications.

FAQ
Q1: What is the load capacity of this 3 inch heavy duty caster?
A: This 3 inch heavy duty caster has a load capacity of 80 kg per caster. For carts or equipment with four casters, the total capacity is 320 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 a swivel caster or a rigid caster?
A: This is a swivel caster with 360° rotation for steering and maneuverability. For applications requiring rigid casters (fixed casters) that roll only in a straight line, we offer alternative configurations. Please contact our sales team for recommendations on rigid caster options.
Q3: Is a brake option available for this caster?
A: Brake options are available upon request. While the standard model (313S1ZSX328U) is a swivel caster without brake, we offer brake-equipped versions for this caster series. If you require locking functionality, please contact our sales team to specify your brake requirements.
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: Is this a steel caster?
A: This caster features a PU (polyurethane) wheel - it is not a steel wheel. For applications requiring steel casters or steel wheels, we offer alternative configurations. Please contact our sales team for recommendations based on your specific requirements.
Q6: 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.
Q7: What equipment is this 3 inch heavy duty caster suitable for?
A: This 3 inch heavy duty caster is suitable for: Industrial carts - workshop carts, service carts, and utility carts; Material handling equipment - platform trucks and transfer carts; Workstations - mobile workstations and assembly stations; Light machinery - small machines and equipment stands; Warehouse equipment - light-duty warehouse carts and trolleys.
Q8: 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 3-inch option (featured here) offers the most compact size with a 108mm load height - ideal for applications where space is limited. Larger sizes provide better rolling efficiency over floor transitions and higher load heights.
Q9: What is the mounting specification for this caster?
A: This caster uses top plate mounting for secure attachment. The robust top plate design ensures stable load distribution and reliable performance. Please contact our sales team for detailed plate dimension specifications and bolt hole patterns to confirm compatibility with your equipment.
Q10: Is this caster suitable for use on uneven floors?
A: The PU wheel provides some shock absorption and performs well on moderately uneven surfaces. For significantly uneven surfaces or applications requiring maximum shock absorption, we recommend Rubber wheels, which offer superior vibration dampening. Please contact our sales team for recommendations based on your specific floor conditions.
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 3 inch heavy duty 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.
