A brushless rotary torque sensor is a finely tuned instrument designed for monitoring and testing torque applications where accuracy and reliability rank paramount. Designed for torque evaluation and verification, the brushless rotary torque sensor is a laboratory grade instrument that is commonly used for quality control, R&D and calibration applications. For use with most power…
There’s no single, universal steel. The fact that steel is an alloy, a mix of different elemental minerals, practically guarantees that there is more than one way to make the stuff. As a result we have steel in a variety of compositions, each of which can withstand a certain amount of abuse and perform well…
During the assembly of parts using an electric torque screwdriver there are many things to consider to achieve proper torque control. Is the joint hard or soft? The material that is being used? Is the screw lubricated or treated with a locking patch? One factor that’s often overlooked when using an electric screwdriver is the…
A helicopter manufacturer had a critical torque application during the routine maintenance process of their aircraft. The rotor of the helicopter requires servicing after every 20 hours of flight. Some of these aircraft are serviced in very remote locations, where air or power is not readily available or reliable. Ensuring proper torque control is achieved…
A pulse tool has the speed of an impact wrench with nearly the repeatability of a clutch based shut-off tool. Containing precision-machined parts the pulse unit is a sealed chamber that is filled with a formulated hydraulic fluid. Pulse blades with a custom designed precision roller push the fluid inside the rotating chamber generating hydraulic…
Designed for high production environments, electric screwdrivers with a high performance brushless motor design provides durability and reduces the standard maintenance costs for standard electric screwdrivers. Management in power tools ensures product quality, cost savings and a reduction in overall failures. Standard Electric Screwdrivers (with Brushes) These ordinary models use brushes and over time there’s…
A manufacturer of heavy-duty trailer suspensions was looking for a way they could verify torque and tension on suspension bolts used on current products and on new products that were in development. The manufacturer was experiencing quality control issues, which were causing production delays and rework expenses. Upon further investigation, the quality control manager traced…
Historical approaches to working with heavy-duty threaded fasteners have aimed at sheer torque power, using long lever arms and heavy hammers on slugging wrenches. More recently, the hydraulic wrench has been viewed as the solution to many problems that require serious torque. But hydraulic wrenches are notorious for their heavy ratchets, bulky compressors and laborious…
TSN cam-over torque wrenches are designed to provide reliable and precise torque control for bolting applications that do not tolerate over-torque conditions. Improper torque control increases manufacturing costs and delays. Using cam-over wrench removes the operator influence out of the fastening process and offers precision and repeatable torque results. A standard click wrench cannot ensure…
You’ve probably heard a lot about stainless steel this and that. But what’s the big deal about stainless steel — and when do you need to choose stainless steel fasteners for your project? First let’s examine what goes into stainless steel that makes it, well, stainless. Ordinary carbon steel met the world’s steel needs for…
