Step 6 – New Linear Bearings

Locate the updated 12mm low-profile linear bearings and install these within the X/Z carriage.

The new bearings feature 5, instead of 4 points of contact with the linear rails. Install the bearings so that one full row of ball bearings will make contact directly on top of each linear rail – this will ensure the best pressure distribution within the assembly.

Our bearing manufacturer suggests lubricating the ball bearings within the assembly using white lithium grease – a dry lubricant should not be used. As these are sealed bearings (once assembled on the shaft), grease must be applied prior to installing the linear rails and completing the seal.
