💡 What is a V groove bearing used for in rail track linear motion systems?

Handy explanation: They guide motion along rails with stable, low-friction travel.

• They support guided motion along rails to maintain alignment
• Common in robotics, CNC carriages, and lightweight linear guides
• Double shields help retain lubricant and keep contaminants out
