Rega is renowned for the quality of its tonearm bearing assemblies. In particular the accurate manufacturing of our bearing housing and bearing spindles. Technical characteristics such as "roundness" and "parallelity" are critical. Over the past three years Rega has found a new manufacturing process which improves on all these characteristics resulting in a micron perfect bearing fit. The RB3000 is the first Rega arm to benefit from these improvements.The entire tonearm structure is designed to have the minimum of mechanical joints while using the stiffest materials in all critical areas.
The tolerance of the RB3000 tonearm is so tight that no adhesive is used at any point throughout the construction. Our latest low mass, precision engineered, vertical bearing assembly has been manufactured to further complement the inherent design philosophy of the Planar 10 turntable.The RB3000 tonearm uses our advanced, preloaded zero tolerance bearing assembly adjusted to less than 1000th of a mm. This gives friction free movement and zero levels of unwanted play. Simply put, friction free bearings with no play enable ridges in the record groove of less than a micron to be read.
The RB3000 also uses our latest award-winning, aluminium, Rega arm tube (each one of which is meticulously hand polished, keeping mass to an absolute minimum) which was redesigned to redistribute mass and further reduce stresses and resonances. This advanced design tube increases the stiffness and rigidity of the overall assembly whilst reducing stress on the bearings even further.

This latest design demonstrates attention to detail and modern CNC engineering advances. This allows new compromises, bringing Rega’s main bearing design closer than ever to the unachievable ideal.The Planar 10 uses a new low mass central bearing assembly. A single piece machined aluminum sub-platter and hardened tool steel spindle run inside a custom brass housing designed with improved mechanical integrity. The complete assembly is cleverly mounted within the chassis to eradicate unwanted potential energy being transferred or stored in the plinth.
