Welding rotator turning roll Self-aligning

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. This type of ball bearing is recommended when alignment of the shaft and housing is difficult, and the shaft may flex. Unlike a single row or double row ball bearing, the self-aligning bearing’s performance will not be affected by misalignment. Therefore, they are particularly suitable for application where misalignment can arise from errors in mounting or shaft deflection inherent in the application. These bearings are made with seal or without seal.

Bearing Assembly

The automatic welding machine P2 is the innovative successor of the successful P models and an efficient and manoeuvrable device for welding truck tarpaulins, tents, awning materials and advertising banners. It produces optionally 20, 30, 40 and 45 mm wide overlap welds and may also be converted for welding in welting ropes. In addition, by mounting hem welding accessories, the automatic machine can without any difficulty be used for the production of 20 mm, 30 mm, 40 mm and 45 mm hems. The heat output of up to 4000 W 230 V AC is infinitely variable from 20 to 700 °C for an individual adjustment to different materials. The P2 starts automatically after the weld head has been swivelled in. In addition, the infinitely variable speed adjustment of the modern generation of motors with their performance of up to 18 m/min., in conjunction with the holding down device for crease free welding, makes for an optimum welding result.

The core of the Rotoweld technology is its unique vision-based penetration control system. It enables any operator to perform high-quality girth welds after just a few hours of training. Like the welder’s eyes and hands, the system continuously analyzes the image of the root weld pool picked up by a video camera integrated into the welding arm. Unique algorithms use this information to adjust welding parameters, such as travel speed, wire feed rate, arc voltage, or weaving width. This constantly adapts the process to varying conditions, such as changes in the gap, alignment, root face, or temperature. The computer’s fast reaction time means the machine can work at high deposition rates and travel speeds at which weld pool conditions are too critical to be sustained by hand.
