Description

Overview:
This Blade Support Cup M12 is a genuine Husqvarna part designed to locate and support metal cutting blades on Husqvarna brushcutters. Made from durable steel with a corrosion‐resistant finish, it provides a stable seating surface to help keep the blade clamped securely and running true. The cup features a precise 14.97 mm centre hole for accurate alignment on the output shaft and is intended for M12 blade mounting systems. It is an OEM component (MPN 503890102) that maintains correct stack height and clamping pressure, helping to reduce vibration and wear. Suitable for a wide range of Husqvarna machines, including the 135R and 143R, this genuine part is a reliable replacement when the original cup becomes worn, damaged or distorted.

Key Features:
- Genuine Husqvarna OEM part for assured compatibility and fit (MPN 503890102)
- Steel construction with a corrosion‐resistant finish for long service life
- Accurate 14.97 mm centre bore for correct shaft location and blade alignment
- Designed for M12 blade mounting systems used on Husqvarna brushcutters and clearing saws
- Helps maintain safe, consistent clamping to reduce blade slip and vibration
- Direct replacement for worn or damaged cups; restores cutting performance
- Simple to fit with standard hand tools; no modifications required
- Supports routine maintenance by protecting the hub, nut and blade interface

Typical Applications:
Used during blade changes or routine maintenance on brushcutters and clearing saws. Replace the support cup if the blade has been slipping, after impact damage, or when the seating surface is scored or deformed. Suitable for grass cutting, scrub clearance and forestry undergrowth work where a metal blade is used.

Also known as:
Blade holder, blade cup, support cup, blade thrust cup, blade support washer, blade boss cup. These terms refer to the same component that supports and locates the brushcutter blade beneath the clamping nut.
