Products Description
The polyurethane caster for hardwood floors is a premium mobility solution engineered for furniture, display equipment, retail fixtures, and applications requiring exceptional floor protection. With a 140kg load capacity per caster and PU tread for non-marking performance, this polyurethane stem caster provides reliable support with smooth 360° swiveling, secure braking, and superior floor protection - essential for environments where hardwood, tile, or other sensitive flooring must be preserved.
The impact on your daily operations: When furniture, display stands, and equipment move across hardwood or sensitive flooring, standard casters can leave marks, scratches, or scuffs that damage floors and create costly maintenance issues. The PU tread delivers non-marking, floor-protective rolling that preserves flooring surfaces while providing smooth, quiet operation. The side brake engages with a simple foot press, locking the wheel to prevent unwanted rolling - keeping equipment securely in place during use. The threaded stem mounting with customization options ensures flexible installation across different equipment types.
The PU (polyurethane) tread offers the optimal balance of floor protection, wear resistance, and rolling efficiency. Unlike hard plastic wheels that can damage floors or rubber wheels that may leave marks, PU provides non-marking performance that protects hardwood and sensitive flooring surfaces. PU also offers superior resistance to abrasion, grease, and oil - making it durable enough for demanding environments while maintaining floor-protective characteristics. The 125mm diameter with 32mm width provides good maneuverability and load distribution. Optional wheel materials (TPR, Nylon, PP, Rubber) and bearing options (Axle Hole, Ball Bearing) are available for applications with specific performance requirements.
Available with threaded stem mounting (customizable) for flexible installation across different equipment types. Available in 3″, 4″, 5″, and 6″ diameters with multiple wheel material and bearing options. The side brake locks the wheel while the swivel remains free for directional adjustment - making this polyurethane caster the ideal choice for furniture, display equipment, and applications where hardwood floor protection is a priority.

FAQ
Q1: What is the load capacity of this polyurethane caster for hardwood floors?
A: This polyurethane caster has a load capacity of 140 kg per caster. For furniture, display equipment, or carts 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: What makes PU the ideal wheel material for hardwood floors?
A: PU (Polyurethane) is the ideal material for hardwood floors because: Non-marking - leaves no marks or scuffs on hardwood, tile, or sensitive surfaces; Floor protection - soft yet durable tread protects flooring from damage; Quiet operation - smooth, quiet rolling that won't disturb; Wear resistance - outlasts rubber and other soft materials; Oil and grease resistance - maintains integrity in various environments. These characteristics make PU the preferred choice for applications where floor protection is paramount.
Q3: What is a side brake and how does it work?
A: A side brake (featured on this model) locks only the wheel (preventing rolling movement) while the swivel mechanism remains free to rotate - allowing directional adjustment even when the brake is engaged. To engage, simply press the brake lever with your foot; to release, press again. This is ideal for applications where equipment needs to stay in position but may need to be reoriented without releasing the brake.
Q4: What is the difference between a side brake and a total lock brake?
A: A side brake (featured on this model) locks only the wheel - the swivel mechanism remains free to rotate, allowing directional adjustment even when stationary. A total lock brake locks both the wheel and the swivel mechanism, completely fixing the caster in position. Choose side brake for applications where directional flexibility while locked is beneficial; choose total lock brake for complete stationary security on sloping surfaces or where equipment must remain completely fixed.
Q5: 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 non-marking performance; 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.
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 moderate use with lighter loads. 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 polyurethane caster suitable for?
A: This polyurethane caster is suitable for: Furniture - heavy furniture, sofas, tables, and worktables; Display equipment - retail displays, exhibition stands, and fixtures; Commercial equipment - store fixtures and merchandising units; Office equipment - workstations and office furniture; Institutional equipment - equipment in schools, hospitals, and facilities with hardwood or sensitive floors.
Q8: What are the available sizes for this polyurethane caster?
A: This polyurethane caster is available in 3-inch, 4-inch, 5-inch, and 6-inch diameters. The 5-inch option (featured here) offers the best balance of load capacity, rolling efficiency, and load height (154mm) for most furniture and display equipment applications. Smaller sizes are suitable for compact equipment and applications requiring lower load height.
Q9: Is the threaded stem size customizable?
A: Yes. This caster features customizable threaded stem mounting - we can configure stem sizes to match your specific equipment requirements. Please contact our sales team with your required stem diameter, thread type, and length when ordering.
Q10: 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.
Q11: Does Xingteng offer custom polyurethane caster solutions for hardwood floors?
A: Yes. With over 30 years of manufacturing experience and in-house engineering capabilities, we offer custom caster solutions including: custom stem sizes, special wheel materials, specific load capacities, and application-specific designs - all optimized for hardwood floor protection. Contact our sales team to discuss your requirements.
Q12: What is the typical lead time for this polyurethane caster?
A: Standard lead time is typically 20-45 days depending on order quantity, wheel material selection, 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.
