Ruland Jaw, 19.1mm Outside Diameter, 6/5.5mm Bore, 27.2mm Length Jaw Coupling

Two Thyristors (SCR) configuration
3500V_RMS isolating voltage from the metal base
Industrial standard package INT-A-PAK
High surge capability

UL approved file E78996

The Ruland D bore zero backlash jaw coupling hub is a precision-engineered component designed to ensure a positive drive in applications where slippage is not an option. It is part of a three-piece coupling system consisting of two aluminum hubs and an elastomeric insert, known as the spider, which facilitates torque transmission while minimizing backlash. This lightweight, low-inertia coupling can operate at speeds of up to 8,000 RPM, making it suitable for high-speed machinery and motion control systems requiring precise, vibration-free performance.

Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities
It is machined from bar stock that is sourced exclusively from North American mills
RoHS3 and REACH compliant

Thyristors - Vishay Semiconductor

A Thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. They act as bistable switches, conducting when their gate receives a current trigger, and continue to conduct while they are forward biased. Thyristors are synonymous to Silicon-Controlled Rectifier (SCR).
Encapsulated modules with electrically isolated base plate. Suitable for applications such as battery chargers, welders and plating equipment, regulated power supplies and temperature and speed control circuits.
