Custom Wave Springs from Smalley Smalley can manufacture custom Wave Springs quickly and economically to meet your specific application requirements. Because force and deflection requirements are application-specific, custom springs are often needed. With Smalley's No-Tooling-Cost™ manufacturing process, customs can be produced from .157" to 120" diameters in carbon steel, stainless steel, or other readily available exotic alloys. Prototypes can be available in as little as two weeks for testing. Free samples are available of standard parts for testing.

10 tips for specifying electric linear actuators Electric rod-style actuators offer enhanced performance, control and efficiency over their fluid power (pneumatic and hydraulic) counterparts. However, because of the higher initial cost of electric actuators and their unique characteristics vs. a fluid power cylinder, it is important to fully understand the application requirements. Learn how to analyze loads, forces, application footprint, environment and more. Download the Tolomatic white paper.

| NASA all-electric plane undergoes structural ground tests | |
| NASA is making progress on the road to first flight for the agency's first all-electric X-plane (and first piloted X-plane in two decades), the X-57 Maxwell. Currently in its first configuration as an all-electric aircraft (called Mod II), X-57 underwent a series of structural ground tests, giving engineers at NASA a look at the vehicle's predicted characteristics during flight. These tests, which included ground vibration testing and cruise motor controller vibration testing, marked important tasks to check off as NASA moves X-57 closer to taxi tests.
