Solid Shaft Collar 20Mm Bore 40Mm OD Fits Sbr Series Rails As A Hella Secure Locking Stopper For Cnc Machines Made From Anodized Aluminum Alloy With M5 Screw Setup Ensuring Rock Solid Stability To Hit Marks Every Time With Zero Wobble Guarantee

Pack of 4 sealing collar stopper for sbr 20 cnc linear rails
✔️ Solid aluminum 40OD 20 bore 12 thick m5 screw set of 4

These metal rings secure linear motion systems preventing unwanted sliding on SBR series guides. They provide stable axial positioning for DIY routers or industrial setups. Anodized aluminum resists oxidation while ensuring durability during repeated mechanical adjustments across various workshops.

✅ 20 millimeter inner diameter fits standard round shafts cleanly
✅ 40 millimeter outer width ensures robust support for heavy loads
✅ Includes four pieces packed together for multiple project needs
✅ M five screw clamp allows tool free mounting without surface damage

💡 What prevents sliding movement on linear motion equipment during cuts?
Shaft collars lock carriage position precisely without permanent modification of your equipment frame.
= Stops axis drift effectively by clamping tightly against the shaft during high stress operations
= Allows you to adjust depth stops easily using only a hex key tool
= Keeps machine calibration intact for repeatable project results every single time
