# MAXSwerve

## MAXSwerve Module Overview

The 3in MAXSwerve Module ([REV-21-3005](https://www.revrobotics.com/rev-21-3005/)) is compatible with the REV ION System, features a 3in Swerve Wheel, and is commonly used in a set of four to build a swerve drivetrain. This module gives a robot the ability to drive forward and backward, side-to-side, and rotate simultaneously without sacrificing traction. The 3in MAXSwerve Module uses the small size and low mass of the [NEO 550 Brushless Motor](https://www.revrobotics.com/rev-21-1651/) and UltraPlanetary Gearbox to save a significant amount of space and weight.

### Greasing Guide

When assembling the MAXSwerve Module we recommend adding grease during assembly and re-applying as needed for the maintenance of your mechanism. For most applications, using [White Lithium Grease](https://www.amazon.com/dp/B06XY6QKS7?ref_=cm_sw_r_cp_ud_dp_P3B2T1TKR60YKSY7R4XA\&peakEvent=4\&dealEvent=1) or [Red Tacky Grease](https://www.amazon.com/Lucas-Oil-10574-Tacky-GREASE/dp/B0049SUK5Y?th=1) will provide sufficient lubrication.
