EquaBearings are priced at $190.00 each.

EquaBearing isolation bearings provide superb lateral isolation AND damping for audio/video components, racks, and loudspeakers, while simultaneously coupling AND decoupling same to and from a supporting structure - either an energy absorbing (damping) platform or the floor.

The isolation bearings are 1.840" in diameter and measure 1-5/16" high.

Isolation bearings in groups of three (3) create a "plane" without requiring precise leveling, although four (4) Bearings may be used if so desired.

Like all similar devices, our isolation bearings should not be placed on carpeting or any "soft" or resilient flooring. And, neither should they be placed upon a "platform" which is then placed on any "soft" floor coverings. Without solid coupling to the floor, the benefits of these (bearing) devices afforded to the supported equipment may be greatly diminished. Furthermore, racks, and loudspeakers especially, could be rendered seriously unstable. Accordingly, we highly recommend using Bearings with Spike-Adapters to penetrate floor-covering. With Spike Adapters, the maximum height to the top of the Bearing is 2.40".

The EquaBearing consists of a single 1/2" Grade-5 Tungsten Carbide Ball which couples/decouples two (2) vertically opposed hard-coated aluminum 7075 alloy discs which have Tungsten Carbide Races that are diamond lapped to a mirror finish of better than 5-microinches (.000005"). The superior materials and finishes of the TC Ball and Races define the sensitivity and ultimate performance of the bearing. No other competing isolation bearing has Tungsten Carbide Races and none compare remotely with regards to the finish of their inferior (steel or aluminum) races.

The quality and performance of such an isolation bearing is dependent upon the mechanical properties of the chosen materials and the finish of the races and the ball. These criteria define the sensitivity and durability of the bearing - both prerequisites for ultra-high performance.

Tungsten Carbide is the material of choice for an isolation bearing ball and race because of its extraordinarily high modulus of elasticity, hardness, toughness, and vibration transmissibility. Tungsten Carbide has exceptional resistance to abrasion, galling, fretting, and surficial "micro-welding", and it exhibits very low dry coefficient of friction values as compared to steels - critical issues especially effecting "dry" bearing performance, load capacity, and longevity. The hardest heat-treated bearing steels are grossly inferior to Tungsten Carbide in this application.
 
The EquaBearing has no weight limit within the confines of the subject application, and its extraordinary durability assures a lifetime of peak performance.

Our isolation bearing employs aluminum 7075 alloy discs that are ideal due to their superb transmissibility of vibratory energy and their very high-strength, plus their hard-coat finish, enhances their function and durability.

The unique Bearing design includes interlocking "male/female" profiles with an o-ring on the bottom disc which limits the "travel" of the ball to about 3/32" from center, and retains the ball in the races. The o-ring acts as a "soft” circumferential bumper, and also contributes to vibration damping. Thus, the Bearing discs are very resistant to separation by excessive lateral movement unless there is sufficient force to "lift" the upper disc beyond the "engagement" of the lower disc. And, the ball cannot roll out of the races and impact the aluminum discs, which could possibly cause particles to enter the race and impede the free movement of the ball.

The EquaBearing provides a level of stability and security never before offered by a similar ball bearing device. And, the EquaBearing is not subject to "self-contamination".

Moreover, because the upper disc "overhangs" the lower disc, the gap between them is not straight through to the races and ball. Instead, the gap is "broken" by two right angles and a vertical ascent which significantly discourage the entry of air-born contaminants that could impede the free movement of the ball. The EquaBearing resists external contamination much better than any other "unsealed" isolation bearing device.

Finally, the EquaBearing is sold only as a "complete bearing"... with both bottom and top races. The "heart"of any such isolation bearing is the ball and the races. Using such a device with only one race disregards the fundamental basis of the bearing's function and performance. Other serious issues aside, relegated the ball to direct contact with a component or loudspeaker (or any intermediate "flat plate"), or down-facing against a platform, in lieu of a second precision spherical race, guarantees reduced performance of the device. Quite simply, half a bearing is half a bearing!
The EquaBearing is incomparable with regards to features and performance, but also sets a new standard of value when compared fairly with competing isolation bearings.

The EquaBearing is comprised of (2) two vertically opposed bearing-discs which retain a single 1/2" ball in races which have spherical radii that are larger than the radius of the ball, allowing the ball to move 360-degrees in a lateral direction. Vibratory energy emanating from a component, loudspeaker, or rack which is directed laterally, will cause the ball to move along the contour of the races, and "force" the ball to "climb" upwards against the weight of the supported equipment. Thus, a significant portion of the lateral energy is dissipated, or used-up as "work" (damped). Further dissipation occurs by excess lateral energy being "redirected" downward through the ball and lower bearing disc, into the high-damping o-ring, with the remaining energy flowing into a supporting structure - either the floor or an energy absorbing platform. Alternately, laterally directed vibratory energy emanating from the floor which passes into the Bearing will result in the same ball movement, providing energy dissipation (damping) and lateral isolation.

As the ball moves in the races, the Bearing maintains a continuous flow of vibratory energy (coupling) while the upper and lower discs move independently (decoupling) - as only a true "rolling-member" bearing can.

The EquaBearing is made with the very best, task-specific materials, is machined to the very closest tolerances, and has the finest finishes. EquaBearing are in a class by themselves - providing features and performance until now, never available.
