3 Critical Problems Your Linear Motion System Can’t Afford
Premature Wear & Downtime
Cheap bushings degrade 40% faster under heavy loads, causing unplanned stops and costly replacements. LMK8UU’s hardened steel construction extends lifespan by 300%+.
Misalignment & Friction Loss
Poor tolerances (±0.1mm) lead to binds and stuttering. Our LMK8UU bushings maintain ±0.01mm precision for seamless CNC/robotics operation.
Compatibility Nightmares
8mm shaft bushings vary by brand. YIDI’s LMK8UU matches HIWIN/THK/NSK standards, ensuring drop-in replacement for 90% of machines.

LMK8UU Linear Bushings – Your Top Questions Answered
✅ What’s the difference between LM8UU and LMK8UU bushings?
LM8UU is the standard open-type bushing, while LMK8UU features a flanged design for easier mounting and axial load support. Both fit 8mm shafts, but LMK8UU offers better stability in vertical applications.
✅ Can I get a sample before bulk ordering?
Yes! We offer free samples (shipping fee applies). Request via our contact form – delivered in 3-5 days via DHL.

✅ What’s the MOQ for OEM/ODM orders?
Standard LMK8UU: 100 units. For custom designs (e.g., DLC coating, non-standard lengths), MOQ starts at 500 units. Request a quote.
✅ How do I install LMK8UU bushings on my CNC machine?
Follow these steps:
- Clean the 8mm shaft with isopropyl alcohol.
- Press the bushing into the housing (use a mandrel for even force).
- Secure with retaining rings if using flanged (LMK8UU-F) type.
- Lubricate with PTFE grease (included in self-lubricating models).
✅ What payment methods do you accept?
We support:
- TT (Bank Transfer) – 30% deposit, 70% before shipment.
- L/C (Letter of Credit) – For orders over $10,000.
- PayPal – For samples and small orders.
- Western Union – Fastest for urgent shipments.
