Description
The high center of gravity design and precision tolerances of the Teres
bearing provide superb dynamic stability. The large 3/4 inch bearing
spindle is finely polished and its large surface area offers superb
sonic performance.
The Teres bearing design is a traditional upward opening bearing. However,
like popular inverted bearings the majority of the assembly is moved up
inside of the platter. This places the platters center of gravity below
the top of the bearing. The result is the excellent dynamic stability that
an inverted bearing delivers. However, unlike an inverted bearing
superior lubrication is provided by an oil bath.
The bearing is designed with large amount of surface area to maximize
viscous damping. The oil in the bearing exerts a smooth, constant
resistance as the platter rotates adding to speed stability.
The bearing is machined from stainless steel and brass.
A hardened ball bearing inserted into the bottom of the spindle shaft
rides against a Delrin and brass thrust plate. The large 3/4 inch
spindle shaft has been polished to a a superbly smooth (4 - 8 micron)
finish. The clearance between the bearing surfaces is only a few 10
thousandths of an inch for excellent stability.
