1 Dear Colleague, Thank you for visiting our website and downloading a product catalog from the R.M. Hoffman Company. We hope this information will be useful to you in solving the application you are working on. The R.M. Hoffman Company is located in the Silicon Valley and has been in business for over years. We are engineers who specialize in mechanical components such as gearboxes, flex couplings, rotary unions, and torque releases, as well as hardware items such as actuators, brakes, clutches, and electrical slip rings. We sell our solutions worldwide to semiconductor, medical, packaging, robotic machine and other builders. Quite often we find that our customers want a customized version of standard product offerings and we take pride in our ability to help match our customer s engineering requirements to the exact product needed. We work closely with our customers to provide modified products or an assembly of products. Please give us a call and let us know how we can assist you. We look forward to talking to you soon. Thank you. The R.M. Hoffman Team 73 info@rmhoffman.com R.M. Hoffman Company 5 San Lazaro Avenue, Sunnyvale, CA.73. info@rmhoffman.com

Eine weitere Einschränkung der Zwischenwellenlänge ergibt sich durch die biegekritische Drehzahl. * The limitation of spacer length to 00 mm is due to the manufacturing process. A further limitation of the spacer length is due to critical speeds.
