3 Critical Challenges in Linear Motion Systems (And How SK12 Solves Them)
✖ Misalignment & Premature Wear
Poorly supported rails cause 40% faster degradation of linear components. Our SK12 supports maintain ±0.01mm parallelism under full load.
✖ Vibration & Noise
Standard supports transmit vibrations, reducing machine accuracy. YIDI's dampened aluminum housing cuts noise by 35%.
✖ Limited Load Capacity
Competitor SK12 supports fail at 800N. Ours handle 1,200N dynamic loads with steel-reinforced bases.

SK12 Linear Rail Support FAQs
A: SK12 supports are designed for square rails (12mm width), while SG12 fits round shafts (12mm diameter). SK12 offers higher load capacity (1,200N vs. 800N) and better rigidity for CNC applications.
A: Yes! Our SK12 supports are cross-compatible with THK HSR12A and HIWIN MGN12 rails. We provide compatibility charts for all major brands.
A: Mounting is straightforward:
- Secure the support base to your machine frame using M4 bolts.
- Slide the rail into the support’s groove (ensure 0.01mm gap for thermal expansion).
- Tighten the side screws to 0.8Nm torque.
A: MOQ is 500 units for custom lengths/coatings. Stock items (80mm length) have no MOQ – order as few as 1 piece for testing.
A: Yes! We provide free samples (you cover shipping). Request yours here – shipped within 24 hours.
A: Maintenance is minimal:
- Every 6 months: Clean the rail groove with a dry cloth.
- Annually: Reapply lithium grease (included in our maintenance kit).
- Never: Use water or solvent cleaners – they damage the anodized finish.

Customer Reviews: What Engineers Say About YIDI Motion
"We switched from a European supplier to YIDI for our robotics assembly lines. The SK12 supports were identical in performance but saved us $4,200/year on a 500-unit order. Their OEM service let us brand the supports with our logo – a huge plus for our clients."
Verified Purchase – 200 units of SK12-80mm | Delivered in 12 days
"Medical-grade equipment requires zero compromises on quality. YIDI’s SK12 supports passed our ISO 13485 audit with flying colors. The stainless steel version met our corrosion resistance needs for surgical robotics. Highly recommend!"
Verified Purchase – 150 units of SK12-100mm (Stainless) | Delivered in 18 days
"Our automated welding cells run 24/7. The extended temperature range (-10°C to +80°C) of YIDI’s SK12 supports was a game-changer. We’ve had zero failures in 14 months of continuous use. The 2-year warranty gives us peace of mind."

Customer Testimonials
"YIDI’s SK12 supports reduced our CNC downtime by 60%. The precision is on par with HIWIN but at half the cost. Their technical team even helped us optimize our rail spacing."
"We tested 5 suppliers before choosing YIDI. Their IP65-rated SK12 supports survived our salt spray tests (100+ hours) where others failed. Delivery was on time despite the global shipping crisis."
