Anji Cazen Hardware Factory Limited is one of the leading manufacturers and suppliers of swivel chair mechanism in China. With abundant experience, we warmly welcome you to buy durable swivel chair mechanism at competitive price from our factory. If you have any enquiry about cooperation, please feel free to email us.
The MECH301 is a light-duty steel swivel mechanism built for task and office chairs, with two independent levers - one for seat height adjustment, one for tilt locking. It's BIFMA-tested, powder-coated for corrosion resistance, and manufactured on a fixed 220mm x 220mm mounting pattern for predictable compatibility across standard chair bases and seat pans.
We supply this mechanism both to chair factories building new models and to distributors sourcing replacement mechanisms for existing chair lines. Either way, the priority is the same: consistent function, batch-to-batch dimensional accuracy, and a mechanism that won't come back as a warranty claim.
Why This Mechanism Holds Up in the Field
Two-Lever Function, No Guesswork
One lever controls height, the other
locks tilt position, giving end users clear, separated control without
a multi-position dial that's harder to explain to end customers.
BIFMA-Referenced Testing
Cycle-tested for load and lock durability before mass production sign-off, reducing post-shipment failure claims.
Fixed 220x220mm Mounting Pattern
Matches the industry-standard hole
spacing used by most task chair seat pans and bases, simplifying fitment for new assembly lines and replacement orders alike.
Corrosion-Resistant Finish
2.5mm steel plate with sand-polished
surface and black powder coating, built to hold up under daily commercial use (offices, call centers, training rooms).
15-20 Day Standard Lead Time
Regular production runs ship faster
than most custom mechanism orders, useful when you're filling a gap
in an existing chair production schedule.
Replacement-Order Friendly
Same spec, same mounting pattern batch after batch, so you can reorder for after-sales/replacement stock
without re-verifying fitment every time.

How the Two-Lever Function Works
Height Lever - Raises or lowers seat height using the connected gas lift; standard pneumatic height adjustment travel.
Tilt Lock Lever - Locks or releases the seat's tilt/rock function at the current angle, up to 28° of tilt range.
💡 This two-lever layout is a common configuration for entry-to-mid-level task chairs where a simpler, more intuitive control set is preferred over multi-function synchro mechanisms with tension knobs.
Quality Control & Testing
As a moving, load-bearing component, the MECH301 goes through a different QC path than static parts:
Load testing on the height adjustment and locking function.
Cycle/fatigue testing on the tilt-lock lever to check for long-term wear.
Corrosion resistance check on the powder-coated finish.
Dimensional check on the 220×220mm mounting pattern for every production batch, to keep replacement orders consistent with earlier shipments.
Pre-shipment random sampling (AQL) before container loading.
🏡 Since 2004, Cazen has manufactured mechanisms and chair components in-house, so tooling, testing, and batch consistency stay under our own control rather than being outsourced to third-party assemblers.
Typical Applications
Task chairs and swivel office chairs
Call center and open-plan office seating
Training room and meeting room chairs
Replacement/aftermarket stock for existing chair models already in the field
Frequently Asked Questions
Q: Will this mechanism fit our existing chair base and seat pan?
A: Most likely, if your chair uses the standard 220mm × 220mm mounting pattern. Send us photos or measurements of your current mechanism and we'll confirm before you order.
Q: What's the difference between this task mechanism and a synchro or knee-tilt mechanism?
A: The MECH301 is a simpler two-lever task mechanism (height + lock only). Synchro and knee-tilt mechanisms add tension control and a different tilt geometry for higher-end ergonomic chairs - we can advise which fits your target price tier.
Q: Can we order this as a replacement part for chairs already in the market?
A: Yes - this is a common use case. Because the mounting pattern and function are held consistent batch to batch, it works well for after-sales replacement stock.
Q: What is the standard lead time?
A: 15–20 days for regular production runs on standard specification orders.
Q: What are your payment terms?
A: We accept T/T and L/C at sight for standard export orders.
Sourcing a Mechanism for a New Chair Model or a Replacement Order?
Send us your target chair design or your current mechanism's specs - we'll confirm fitment, function match, and pricing within 24–48 hours.
