12mm eccentric collar single, slim X-narrow stainless steel locking clamp for shaft, linear slide unit sealed ball bearing compatibility, precision motion control low-profile fit ideal for automation

Single 12mm eccentric stainless steel shaft collar
✔️ Slim X-narrow locking clamp for 12mm shaft, sealed bearing fit

This single-piece 12mm eccentric collar is a low-profile stainless steel shaft clamp used to lock shafts on linear slide units, motion control rigs, and sealed ball bearing assemblies.

✅ 12mm bore for standard metric shafts
✅ Stainless steel slim X-narrow design for tight fits
✅ Eccentric locking action for secure shaft clamping
✅ Compatible with linear slide unit setups and sealed ball bearing housings
✅ Single collar pack, ideal for motion control and automation hardware

💡 How does an eccentric shaft collar help secure shafts on linear slide units and sealed ball bearing setups? Eccentric collars squeeze the shaft off-center to create a tight clamp without marring surfaces, making them handy for precision assemblies. - Produces radial pressure to minimize axial play on linear slide unit and sealed ball bearing systems - Preserves sealed ball bearing integrity and works with ceramic or steel bearing components - Low-profile X-narrow form factor suits motion control, compact automation, and tight-fit hardware
