Products Description
The 2.5 inch swivel caster is a dual-wheel mobility solution engineered for office chairs, furniture, medical equipment, and light commercial applications. With a 50kg load capacity per caster and a dual-wheel design, this stem caster provides reliable support with smooth 360° swiveling, enhanced stability, and quiet, floor-protective rolling - essential for environments where noise reduction, floor protection, and equipment stability are priorities.
The impact on your daily operations: When office chairs, furniture, and medical equipment need to be moved across floors throughout the day, smooth-rolling, quiet casters make the difference between a comfortable user experience and disruptive noise. The PU wheel delivers quiet, non-marking rolling that protects office and healthcare floors while providing smooth maneuverability. The dual-wheel design enhances stability by providing a wider footprint, reducing the risk of tipping - particularly valuable for tall office chairs, medical equipment stands, and furniture with high centers of gravity. The threaded stem mounting ensures secure, vibration-resistant attachment.
The PU (polyurethane) wheel offers an optimal balance of floor protection, quiet operation, and wear resistance. PU is widely recognized as one of the best materials for office, healthcare, and furniture 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, PU provides non-marking performance and a smooth rolling experience. The dual-wheel design with 52mm total width distributes load more effectively, improving stability and reducing pressure on floors.
Available with threaded stem mounting (M10 × 25mm, customizable) for secure, vibration-resistant attachment to office chairs, furniture, and medical equipment. The smooth 360° swivel action ensures effortless steering and maneuverability - making this 2.5 inch swivel caster the ideal choice for office chairs, furniture, and medical equipment applications.

FAQ
Q1: What is the load capacity of this 2.5 inch swivel caster?
A: This 2.5 inch swivel caster has a load capacity of 50 kg per caster. For office chairs, furniture, or equipment with four casters, the total capacity is 200 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 dual-wheel design?
A: The dual-wheel design provides several advantages for office, furniture, and medical applications: Enhanced stability - wider footprint reduces tipping risk, especially for tall chairs and equipment; Better load distribution - weight is spread across two wheels, reducing stress on each wheel and extending service life; Smoother rolling - dual wheels handle floor imperfections better than single wheels; Improved floor protection - wider contact area reduces pressure on floors. These characteristics make dual-wheel casters ideal for applications where stability and smooth movement are priorities.
Q3: What are the advantages of PU wheels for office and medical applications?
A: PU (Polyurethane) wheels offer: Quiet operation - soft tread significantly reduces rolling noise, ideal for offices and healthcare facilities; Floor protection - non-marking material protects office and medical flooring; Wear resistance - outlasts rubber and other soft materials; Oil and grease resistance - maintains integrity in various environments; Smooth rolling - comfortable and effortless movement. These characteristics make PU the preferred choice for office chairs, furniture, and medical equipment.
Q4: What is the mounting specification for this caster?
A: This caster uses threaded stem mounting - M10 × 25mm as standard, with custom stem lengths and thread specifications available upon request. This standard metric size is compatible with many office chairs, furniture, and medical equipment. For applications requiring different thread sizes or lengths, please contact our sales team.
Q5: What equipment is this 2.5 inch swivel caster suitable for?
A: This 2.5 inch swivel caster is suitable for: Office chairs - executive chairs, task chairs, and ergonomic seating; Furniture - sofas, tables, cabinets, and display fixtures; Medical equipment - medical carts, equipment stands, and hospital furniture; Light commercial equipment - retail fixtures and display stands; Institutional furniture - school and office furniture.
Q6: Is this caster considered heavy duty?
A: This caster is designed for light to medium applications with a 50kg load capacity per caster. For its compact 2.5-inch size, it provides reliable, heavy-duty performance for office chairs, furniture, and medical equipment. For applications requiring higher load capacities (100kg+), we offer larger heavy-duty caster series - please contact our sales team for recommendations.
Q7: What is the difference between this dual-wheel caster and a single-wheel caster?
A: A dual-wheel caster (featured here) has two wheels side by side - providing enhanced stability, better load distribution, and smoother rolling. A single-wheel caster has one wheel - lighter, more maneuverable, but with less stability. For office chairs and medical equipment where stability is important, dual-wheel casters are the preferred choice. For applications where maneuverability is the priority, single-wheel casters may be suitable.
Q8: Is this caster suitable for use on all floor types?
A: Yes. The PU wheel is suitable for: Hardwood - non-marking, floor-protective; Tile and ceramic - smooth, quiet rolling; Laminate and vinyl - floor-protective performance; Carpet - smooth rolling on low-pile carpet. PU provides excellent performance across a wide range of floor surfaces without marking or damaging.
Q9: 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.

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 for office, furniture, and medical equipment applications. Contact our sales team to discuss your requirements.
Q11: What is the typical lead time for this 2.5 inch swivel caster?
