68 AIRLOCK
Achieve ultimate edge-finishing versatility with the bernette 68 AIRLOCK Serger & Coverstitch Combo Machine. Engineered for garment creators, activewear designers, and home textile artisans, the b68 AIRLOCK combines 2-, 3-, 4-, and 5-thread overlock, coverstitch, and combo stitches into a single high-speed workstation.
Featuring Automatic Air Threading for effortless looper setup, Micro Thread Control (MTC) for precise seam wrapping, the Free Hand System (FHS) knee lifter, a narrow free arm, 5 LED sewing lights, and a spacious slide-on extension table, this machine delivers professional-grade seams and hems with ease.
Overlock, coverstitch, chainstitch, and safety combo stitches on one machine.
One-touch air threading blasts thread through the loopers instantly.
Fine-tune looper thread volume to prevent looping or tunneling.
Hands-free presser foot control for feeding bulky materials.
Frustration-Free Setup
Automatic Air Threading
Engage the air threader connector switch and press a button to blast threads through internal looper tubes in seconds, cutting out one of serging's most tedious setup steps.
Quick Conversions
Color-Coded Thread Paths
Clear color-coded paths guide thread routing for quick 2-, 3-, 4-, or 5-thread conversions, making it easy to switch stitch types without guesswork.
Precision Finishing
Micro Thread Control (MTC)
MTC lets you adjust looper thread volume with a simple turn, ensuring stitches wrap cleanly around fabric edges without puckering or loose loops.
Fabric Handling
Differential Feed Dial
Differential feed eliminates waviness on knits and stretch fabrics, keeping seams flat and professional-looking on even the trickiest materials.
Ergonomic Control
Free Hand System (FHS) Knee Lifter
Lower and raise presser feet hands-free using the FHS knee lifter, keeping both hands on bulky materials as you feed them through.
Project Flexibility
Free Arm & Slide-On Table
Convert to the narrow free arm for sleeve cuffs, or attach the expansive slide-on table to support heavy home decor pieces and wide fabrics — the same machine adapts to both small and large-scale projects.
Seamless Transitions
Upper Looper Disengagement Switch
Disengage the upper looper with a simple switch to set up coverstitch or chainstitch patterns without rethreading the whole machine, saving time when switching between techniques mid-project.
Lighting
5 LED Workspace Lights
Five LED lights illuminate the entire work bed, cutting down on shadows so you can see exactly where loopers and needles are working.
Stitch Versatility
2/3/4/5-Thread Versatility
Switch between 2-, 3-, 4-, and 5-thread overlock, coverstitch, chainstitch, and safety combo stitches on a single machine — one workstation covers everything from lightweight seam finishing to heavy-duty construction.
Cleanliness
Built-In Cut-Off Waste Bin
Trimmed fabric edges collect directly in the built-in cut-off waste bin as you serge, keeping your workspace clear without extra cleanup between seams.
Precision Adjustments
Cutting Width Dial & Rolled Hem Lever
The cutting width dial lets you fine-tune how much fabric the knives trim as you serge, while the rolled hem lever converts your machine for narrow, professional rolled hems on napkins, scarves, and delicate edges.
