Description
The 75mm Standard: The 75mm (approx. 2.95-inch) diameter is globally recognized as the perfect balance for ergonomic task chairs and kids’ seating. It maintains a low, stable center of gravity while easily clearing standard carpets and hard floors.
Universal Stem Compatibility: Engineered to fit standard aluminum or nylon 5-star bases flawlessly. Our precision-machined stems (typically 11x22mm grip ring) guarantee a snug, wobble-free installation—eliminating the loose, rattling wheels that lead to customer complaints.
Optimized Weight Distribution: The 86mm installation height and dual-wheel design (62mm total width) are scientifically calculated to distribute commercial loads evenly, preventing base cracking and ensuring a silent, frictionless roll.
As a direct manufacturer supported by seven deep-cooperation OEM factories in China, we deliver high-end components exclusively for B2B buyers in Europe and South America. We reject low-quality price wars, focusing instead on strict quality control and industry standards like SGS and BIFMA. Our office chair caster wheels and office chair wheel lock systems are engineered for wholesalers and furniture designers who demand premium parts. By sourcing our caster office chair wheels, you ensure superior manufacturing support, custom capabilities, and direct factory advantages for your supply chain.
Intuitive Securing Mechanism For premium seating, stability and mobility must coexist. Our office chair wheel lock features a highly reliable, simple lock and release function. Users can instantly secure their chairs for focused work or release the brake for smooth gliding. This office chair wheel lock perfectly matches ergonomic seating and high-end setups. Incorporating a robust office chair wheel lock minimizes unwanted movement when absolute stability is required.
Heavy-Duty Materials & Sizing Load capacity and longevity are primary concerns for B2B procurement. We manufacture our caster office chair wheels using a durable combination of PU (Polyurethane) and PA (Polyamide) plastic. At a substantial 75mm diameter, these caster office chair wheels provide excellent ground clearance and superior structural integrity. B2B buyers prefer these caster office chair wheels because they handle high weight capacities seamlessly without deformation.
Universal Fit & Floor Protection Procurement requires standardized, hassle-free components. Supplied in a practical set of 5 wheels, these office chair caster wheels are extremely easy to install via a standard universal stem. Furthermore, the premium PU material ensures the office chair caster wheels are kind to most surfaces, guaranteeing silent rolling. These office chair caster wheels actively prevent scratches on hardwood, tile, and carpet.
Customization for Brand Consistency We offer extensive custom colors for your office chair wheel lock orders to match specific design requirements. If you need tailored visual branding for your caster office chair wheels, our engineering team delivers precision matching.

Testing & Quality Assurance: Engineered to Eliminate Warranty Claims
A failing caster means costly customer returns. Watch our rigorous in-house stress tests that prove why our components deliver a zero-maintenance experience.
BIFMA Dynamic Rolling Test
Extreme fatigue testing—rolling over solid obstacles for 100,000+ cycles under load. Ensures the wheel core and raceway never deform.
Heavy-Duty Static Load
Thickened steel brackets and precision bearings easily support maximum BIFMA weight thresholds without stem bending or housing cracking.
Salt Spray Anti-Corrosion
11x22mm stems and housings endure extreme salt spray tests, guaranteeing long-lasting rust prevention for ocean freight and humid climates.
Scientific Material Ratio
A strictly controlled ratio of premium virgin nylon/PU with trace structural composites prevents brittleness and maximizes impact resistance.
Packaging & Logistics: Global Supply Chain Security
Delivering components safely, maximizing container space, and ensuring on-time arrivals separate a true manufacturing partner from a basic supplier.
Frequently Asked Questions
Q1: What is your Minimum Order Quantity (MOQ)?
A: Our standard MOQ is 500 sets. We maintain this baseline to ensure efficient production while remaining accessible for wholesale and manufacturing clients.
Q2: Are product samples available before placing a bulk order?
A: Yes. Standard samples are available and can be dispatched within 7 days, allowing your technical team to conduct in-house fitment and durability tests.
Q3: What are your quality standards for casters?
A: All our white office chair wheel casters strictly meet BIFMA and SGS testing standards, ensuring structural integrity and long-term durability.
Q4: What payment terms do you accept?
A: We offer flexible payment options to match your procurement process, including T/T (Telegraphic Transfer), PayPal, and L/C (Letter of Credit).
Q5: What is the standard delivery time for orders?
A: Our standard production and delivery time ranges from 15 to 30 days, depending on the order volume and specific configuration.
Q6: What trade terms do you support?
A: We support a wide range of international trade terms to suit your logistics needs, including EXW, FOB, C&F, DDP, and DDU.
Q7: What is the difference between a caster, a wheel, and a roller?
A: The three terms are often used interchangeably, but they mean different things.
A caster is the complete assembly — swivel bracket, stem, and wheel — ready to install directly onto chairs, tables, or other furniture.
A wheel is only the round rolling component inside the caster. Material and diameter determine floor compatibility and load performance.
A roller is a narrow single-wheel caster, similar in profile to an inline skate wheel, optimised for smooth gliding on hard surfaces.
For procurement: always specify the full caster, not just the wheel. Include stem type, wheel diameter, floor type, and load requirement — this is what your supplier needs to match the correct component.
Q8: When should I specify a locking caster for my furniture lines?
A: A locking caster (or brake caster) should be integrated whenever the user requires stationary stability during a task. They are highly recommended for sit-to-stand desk chairs, study chairs (focus-enhancing ergonomic seating), medical stools, and elevated bar chairs.
Q9: Which caster material should I choose for hard floors versus carpets?
A: For hard floors (hardwood, tile, concrete), choose Polyurethane (PU) or soft rubber casters to ensure scratch-free protection and a whisper-quiet glide. For soft surfaces (thick carpets or office rugs), choose Hard Nylon casters; their lower rolling resistance cuts through fibers, eliminating drag and strain.
Q10: How do I select the right caster diameter for different types of furniture?
A: Diameter impacts mobility and load clearance:
- 40mm (1.5-inch): Ideal for lightweight product stands, such as clothes racks, small appliance bases, and potted plant bases.
- 50mm (2-inch): The industry standard, perfect for standard office chairs, light shelving, and standard mobile whiteboards.
- 60mm – 65mm (2.5-inch): Ideal for premium ergonomic chairs and heavy-duty gaming chairs.
- 75mm (3-inch) or larger: Highly recommended for heavy utility carts, large industrial equipment, and medical rolling stations requiring maximum clearance and effortless movement.
