V623ZZ 623VV Metal SS V-Groove Guide Pulley Rail Ball Bearing
৳90
If you're building or upgrading a machine with linear rails or tracks, the V623ZZ is a strong candidate for smooth guidance. It's a compact, metal V-groove bearing/pulley that runs on rails or tracks instead of flat surfaces. What makes it useful is its small size, strong construction, and the V-groove that helps it ride reliably without slipping off. The bearings are double-shielded (“ZZ”), which keeps grease in and dirt/dust out — that means less maintenance and longer service life.
It’s especially suited for cable‐guides, sliding motion, or where you need a lightweight, low-profile wheel turning on a rail. A great pick for hobbyist CNC, light automation, or any project needing guided movement in tight spaces.
