Rodobal joint test

Rodobal swivel joints with the MTE suffix have a forged body made of 42CrMo4 alloy steel, heat-treated to withstand very high stresses. Furthermore, the spherical inner ring is made of 100Cr6 carbon steel, therefore tempered and ground on both the spherical surface and in the bore. It is thickly chrome-plated. Between the spherical inner ring and the stainless steel bushing, there is an anti-friction insert, composed of a bronze wire mesh impregnated with PTFE. The anti-friction insert provides permanent lubrication. No greasing is required, either initially or during operation. This avoids the presence of a grease nipple and its related hole on the head body, which would reduce the load-carrying capacity. The sliding spherical coupling is pre-loaded and has very little play; the pre-load prevents an increase in play in the coupling during use. The right-hand or left-hand fine-thread allows precise adjustment of the distance between arms and rods. Rodobal MTE swivel heads are corrosion-resistant thanks to the polished nickel-plating of the head body, the stainless steel bushing, and the chrome-plating and thickness of the inner ring.
