Bearing Components
Description
Bearing components sit between scissor blades at the pivot to control friction and smoothness. Learn about washer types, materials, and how they affect cutting feel.
Bearing Components (ベアリング部品, Bearingu Buhin)
Quick look
- What it is: Mechanical elements within the pivot that reduce friction and control blade movement
- Purpose: Determine smoothness, closing action, and long-term pivot durability
- Range: From basic nylon washers to advanced magnet-bearing hybrids
- Cost factor: Ball bearing screws are the most expensive bearing components and the hardest to replace
Why it matters
Bearing components define the mechanical character of a scissors. The difference between a budget pair and a premium pair often comes down to what sits inside the pivot.
Nylon washers: The most basic bearing solution, found in budget and entry-level scissors. A simple nylon disc reduces metal-on-metal friction at low cost. Functional but offers limited smoothness and wears relatively quickly under professional daily use.
Ball bearing bushings: The standard in premium scissors. Typically built around 7mm ball bearings housed in a precision bushing, these provide exceptionally smooth closing action with minimal effort. The ball bearings distribute load evenly, reducing wear on both the pivot hole and the screw. Most professional stylists who have used ball bearing scissors find it difficult to return to simpler systems.
Magnet-bearing hybrid: An advanced system that combines bearing smoothness with magnetic auto-close power assist. The magnet provides a gentle return force that partially closes the scissors when the thumb releases pressure, reducing the total effort required across hundreds of cuts per day. Found in high-end Japanese and European lines.
Double bearing systems: Some manufacturers use dual bearing assemblies for even smoother action. Naruto Scissors, for example, employs a ダブルベアリング搭載 (double bearing) configuration in their Forte Graber DB model, placing bearings on both sides of the pivot for symmetrical load distribution.
Ball bearing screws represent the highest cost component in the pivot assembly. When they fail or wear out, replacement requires precision matching to the original specifications. Generic replacements rarely provide the same feel, which is why bearing-equipped scissors should always be serviced by technicians familiar with the specific brand.
