Set of 4 Silicon Nitride ceramic hybrid double shielded, radial, deep groove ball bearings.  These bearings are made of stainless steel with ceramic balls (Si3N4), are closed with double metal shields to protect the bearing from dust or any possible contamination, and are pre-lubricated with grease.  The bearings are rated for speeds of up to 100,000 revolutions per minute.

NOTE: These make a great addition to any mount but are intended to be installed during a HyperTuneTM or mount cleaning and relubricating procedure. While they can be simply dropped in and installed without doing a HyperTuneTM, it is not recommended.  If you have any questions please email
You will receive the following with your bearing upgrade kit:

  • Complete set of RA and DEC ceramic hybrid worm gear ball bearings
  • Access to the electronic version of the bearing replacement guide
