• Product Overview

It's a well known fact that one of the weakest points of the mass-produced GEM mounts are the plastic bearings that reside inside. They are made of cheap plastic material and usually have nicks, tears, gashes or sometimes even areas missing from them.  In addition, they tend to dry out and crumble over time with the result pieces ending up in various places in the mount.

To combat that we've come up with a solution for replacement of all of the plastic bearings inside the mount.

Made from 100% virgin PTFE Teflon® material and cut to the exact dimensions of the original bearings, these upgraded Teflon® bearings / bushings will allow your mount to hold the scope load more balanced, more freely and help with all kinds of other mount issues such as Periodic Errors when shooting astrophotograph, mount stiffness, and more.

These are not metal bearings and you will not need to alter the mount in any way in order to use these.

NOTE: These make a great addition to any mount but are intended to be installed during a HyperTune^TM or mount cleaning and relubricating procedure. While they can be simply dropped in and installed without doing a HyperTune^TM, it is not recommended.  If you have any questions please email info@deepspaceproducts.com.

You will receive the following with your bearing upgrade kit:

• 4 - 0.010" Teflon® bearings
• 4 - 0.015" Teflon® bearings
• 4 - 0.020" Teflon® bearings
• Access to an electronic version of the Bearing Calculation Worksheet
• Access to electronic versions of the mount detail photos as offered with the HyperTune^TM Kit
