Varia VS3 Hopper Bearing: Essential for Smooth Grinding

The Varia VS3 hopper bearing is a precision-engineered P5 class double-layer ball bearing that forms the foundation of the grinder’s stepless adjustment system. This critical component enables ultra-precise grind adjustments with 10-micron accuracy, maintains perfect burr alignment, and ensures smooth, vibration-free operation for espresso and filter coffee.

Key Features

Precision Bearing Design

Manufactured to exact specifications for the Varia VS3, the bearing reduces friction and wear, ensuring smooth hopper rotation and alignment. This precision supports consistent grind size and accuracy when making grind adjustments.

Durable and Resistant

Made from premium materials, the bearing withstands coffee oils and residue that can affect performance. It maintains smooth operation over thousands of grinding cycles and works seamlessly with the VS3’s burr set and hopper assembly.

Easy Maintenance

The bearing’s accessible design allows full access for cleaning and inspection during regular grinder maintenance. Replacement is straightforward with basic tools, and clear indicators help you know when to replace or clean the bearing.

Why It Matters

✔ Maintains precise burr alignment for consistent coffee grounds

✔ Enables stepless adjustment with 10-micron precision

✔ Reduces retention and loose grounds in the grinding chamber

✔ Supports smooth, vibration-free grinding for better flavor clarity

Maintenance for Best Results

Regular cleaning and rinsing of the hopper bearing, springs, washer, and surrounding components prevent buildup and extend grinder life. Always unplug the grinder from the power source before maintenance. Proper care protects the bearing’s hardness and stability, ensuring your Varia VS3 grinder performs at peak speed and accuracy.

Keep your Varia VS3 hopper bearing installed and maintained to achieve the best grind quality and durability!
