Edge welded metal bellows are manufactured by welding stamped, metal diaphragms into a long, flexible assembly. The key to the performance of the edge-welded bellows is the thickness and ripple profile of the metal diaphragms. The pressure, stroke length, spring rate and temperature help to determine the material and the thickness of the diaphragm required […]
Servo couplings for a wide variety of applications
Rigid couplings have high torque capacity, torsional stiffness, and zero backlash. Ruland Manufacturing Co., Inc. straight bore rigid couplings have precision honed bores for proper fit and alignment. Proprietary Nypatch coating is used on hardware to resist vibration and maintain holding power. Two-piece styles feature opposing screws for balancing, reducing vibration at higher speeds. Ruland […]
Helical Supports Machinists With Donation To Community College
Helical shared in the donation of $120,000 to the Machine Technology Program at Allan Hancock Community College. The program provides students with a full range of machining courses. Students learn skills of machine technology and using Computer Numerical Control (CNC) machines. Many of these techniques are critical when making flexible couplings and machined springs both […]
Zero-Max’s Clamp Style Hub Design For Handling Larger Shafts And Higher Torque
Zero-Max ServoClass® couplings now feature improved clamp style hub design for handling larger shafts and higher torque. ServoClass couplings are designed for high speed reversing loads and precise positioning requirements in today’s demanding servomotor applications at speeds up to 10,000 rpm. The new clamp style hubs provide superior shaft engagement for these high speed applications. […]
ZERO-MAX ServoClass® added single and double disc coupling sizes
A Single and Double Disc coupling size has been added to the Zero-Max ServoClass® coupling line. The addition of the SD025R and SC025R models handle 5 to 14 mm bore diameters and torque up to 4 Nm. The new size gives designers even more options when planning their systems. Providing high torsional stiffness, these model […]
