NEW BYERS 11-5/16ths" Gear with Spring loaded Worm/Housing


  

  NEW BYERS 11-5/16" gear with matching worm and spring-loaded housing.  

This drive is top-of-the-line. It is the most accurate drive system ever made by Byers Company. The precision stainless steel worm runs in ball bearings, and the worm threads are spring-loaded into the gear teeth to prevent unwanted backlash. The worm housing is designed to compensate for low temperatures, thus, allowing for the expansion and contraction of the gear and the telescope mounting.


A slip-clutch can be supplied to suit the customer's needs. Price will be quoted after I know the shaft diameter.

NEW BYERS 22-5/8", 718-th Gear with Spring loaded Worm/Housing


  

NEW BYERS 22-5/8" 718-th drive w/ double-ended worm, ball-bearing/spring-loaded worm housing. The worm bearing housing is designed to operate at low temperature and is spring-loaded to keep the pressure of the worm threads against the gear teeth to prevent unwanted backlash. This is the LAST one of this size.
The gear is bored is at 2.00", can be bored to customers specifications at no extra cost. A slip-clutch can also be supplied to suit the

customer's needs - Price of the clutch will be quoted after I know the shaft diameter.


This is the last large gear that will ever be available. The 718-teeth is exactly 1/2 Sidereal-Rate, thus it will track the stars exactly when the worm turns at 1 rotation in 2 minutes. If you have a large telescope or intend to build one in the future, this will be the last chance to get a Byers super accurate drive. Shipping cost will depend on the location of where it is shipped. Crating cost is $125 USD
