The V623ZZ and 623VV are specialized V-groove pulley bearings designed for guided linear motion along round shafts, wires, or rails. These bearings are based on the standard 623 series but feature a V-shaped outer ring, making them ideal for use in fishing line rollers, wire guides, and precision motion equipment like 3D printers, CNC machines, and textile machinery.
-
The V623ZZ version includes double metal shields (ZZ) for protection against dust and light debris.
-
The 623VV version includes double rubber seals (VV) for better moisture resistance and quieter operation.
Both versions offer smooth rotation, high load capacity for their size, and long-lasting durability thanks to their chrome steel construction.
