Ruland Disc, 50.8mm Outside Diameter, 13 mm, 25 mm Bore, 46.1mm Length Flexible Coupling

CPF precision resistors are constructed from an alumina substrate with a Nichrome (NiCr) resistor layer. They feature an electroplated tin finish that is 100% matte. Offered in a range of standard case sizes these chip resistors have uniform, accurate dimensions that enable easy placement.

CPF series thin film precision resistors from TE Connectivity provide high stability and close accuracy. These chip resistors have resistance tolerances down to 0.1% and Temperature Coefficient of Resistance (TCR) values as low as 15ppm/°C.

Suitable applications for CPF precision resistors include communications, industrial controls, instrumentation and medical applications.

The Ruland Clamp single disc coupling with keyways is a high-precision mechanical coupling designed for zero-backlash torque transmission, ensuring accuracy and reliability in motion control applications. Its balanced design minimizes vibration at high speeds, improving stability and efficiency. The coupling consists of two anodized aluminum hubs with integrated keyways for secure shaft attachment, along with thin stainless steel disc springs that allow for angular misalignment and axial movement while maintaining structural rigidity. However, it does not support parallel misalignment, requiring precise shaft alignment for optimal operation.

Lightweight and has low inertia making it well suited for applications with speeds up to 10,000 RPM
Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities
It is machined from solid bar stock that is sourced exclusively from North American mills and RoHS3 and REACH compliant
