In Start-Stop Motion, Oil Shear Maintains Brake Operation
The start/stop action of many conveyor and other material-handling equipment applications shortens the life of many of the motion control components, such as motor brakes. One way to combat this issue is to choose motor brakes that use oil shear technology, such as the MagnaShear™ motor brake. With oil shear technology, a layer of automatic…
SMC Spring-engaged Clutches from Ogura
Ogura’s SMC spring-engaged clutches engage any time power is released. When the clutch is disengaged, a magnetic coil pulls back a pressure plate and a series of friction discs, so no torque is transferred between the input and output hubs on the clutch. When the coil is no longer receiving voltage, a series of springs…
Are ultracapacitors poised to replace batteries?
The automotive market seems to be approaching a tipping point in its pursuit of an adequate audience for environmentally friendlier vehicles.

The Clutch You Don’t Hear May Be An Ogura
Ogura has developed a “silent” armature for its industrial clutch and brake V series. In many applications in industries like medical or entertainment extraneous noise is a problem. The silent armature developed by Ogura helps to dampen the sometimes objectionable click a clutch or brake makes when engaging. To accomplish this dampening, the Ogura V…
Oil Shear Proves Itself to be a Concrete Answer
Reading Rock manufactures concrete blocks—just like the ones used to build schools across the country for decades. Production Manager Phil Thacker figures that they’ve manufactured about 22 million of the industry-standard 8-in. blocks in the past four years alone. One reason for this productivity is that Thacker and the Reading Rock team go to great…
Low Cost Solution to SERVO Drives
Most industrial clutches and brakes are measured in the millions of cycles, but when you have applications such as high volume mail sorting machines life needs to be measured in the tens of millions of cycles. To accomplish this high cycle life, Ogura uses ceramic friction material as an option in the AMC series of…

Brake Redesign is a Custom Fit for Forklifts
Engineers at Yale Lift Trucks recently redesigned its existing PK-35 braking system for its next-generation three-wheel truck series. They had to make the new trucks smaller and add a parking brake with a manual release. Several different Yale and Hyster brake sit-down counterbalance trucks use the new PK-35 brake. The company asked for help from…
Improved Design From Minnesota Rubber
Variable speed clutch control devices molded of PEEK change clutch gear ratio more efficiently and are more durable than earlier designs molded and machined of a low performing thermostat material. The PEEK design from Minnesota Rubber and Plastics (MR&P) improves clutch operation while adding to clutch longevity. Clutch control assemblies take a beating. Off-highway vehicle…
Drive Delivers Full Torque at Low Speed and Stays Cool
The Two Speed Drive is for applications up to 30 hp that require a high turndown ratio while maintaining high torque.
