Product Description

M2 Antenna Systems, Inc has improved on the proven OR2800 Series Azimuth Rotor for 2019. Our new thrust collar provides dual thrust bearings and dual seals. The collar and additional seal prevent any output shaft lateral movement, protecting the lower seal. The collar also terminates close to the top plate, reducing the chance of water getting to the top seal. A Zerk fitting allows the bearings to be greased easily.

This kit allows you to upgrade your existing OR2800 rotor to an OR2800G2 top casting assembly with the new collar, dual seals and dual bearings.  This kit will work with an AC or DC version of the OR2800 that has a splined output shaft.  This will not work with the early "keyed" output shaft.  The kit includes a new drive plate (your mast clamps connect to this) since the old drive plate is no longer compatible.  New stainless steel hardware is included to reattach the top and bottom castings.  This kit includes our "OVAL" drive plate that is suitable for a mast up to 3" OD.  For a 2" OD mast, please order the "ROUND"  drive plate.

Grease is not provided with this kit.  We use a product called MAG1. The proceeding link is just for reference and not an endorsement of any particular vendor.  A grease gun is required to properly pack the bearings.


***This kit is not compatible with the OR2300.
Parts list:
1 - OR2800G2 complete top casting
