Minnesota Rubber and Plastics to exhibit at CTI Symposium
Visit CTI Symposium USA at Booth #65 to see and hear Minnesota Rubber and Plastic’s presentation on its capabilities for molding high-performance elastomers and plastics for critical vehicle/powertrain components, assemblies and kitting. CTI is the official Innovative Automotive Transmissions, Hybrid and Electric Drives Symposium. Experts from Minnesota Rubber and Plastics will present its newest technology…
Active Magnetic Bearings Ease Design of High-Speed Machinery
Active magnetic bearings (AMBs) present unique advantages over conventional roller or fluid-film bearings when designing high-speed rotating machinery, such as turbines, compressors, Organic Rankine Cycle systems and flywheel energy storage systems. Unlike conventional bearings, AMBs suspend the target rotor in a magnetic field. The result is a non-contact rotor support system with extremely low friction…
Tapered roller bearings for haulage equipment
Put a few tons on your back, climb steep grades, make a few sharp turns and do it over and over again – that’s what’s expected from haulage equipment. Whether it’s articulating trucks or shuttle cars, they move a lot of material without much space to do it. When Timken tapered roller bearings are installed […]
Emerson Bearing Boston rolls out extra precision bearings
Some industrial jobs require precision beyond that provided by standard bearings. Emerson Bearing Boston, a bearing company catering to Original Equipment Manufacturers (OEM) and Maintenance, Repair and Operations (MRO) markets around the world, rolls out Extra Precision Bearings and shares tips to ensure their peak performance. Extra precision bearings allow for extra fine tolerance and […]
Tapered roller bearings for long wall shearer
The confines of underground mining mean that equipment must become more and more productive without increasing size. When downtime ranges between $30,000 and $50,000 an hour, increased uptime means more profit. Longwall shearer cutters traverse back and forth, stripping layers of coal. Each pass is challenged by intense impact loads and extreme dirt and debris. […]

Timken’s tapered and spherical roller bearings for tunnel boring cutter heads and more
Coal miners work far below the earth’s surface and have little time and less space to deal with unscheduled breakdowns. With enormous rotational forces and constant impact loads on the cutter heads, equipment productivity is paramount, especially when downtime costs between $10,000 and $15,000 per hour for room and pillar mining. Timken offers a range of […]
Plastic pillow block bearings replace metallic solutions
Pillow block bearings play a central role in the food industry. They are used in the continuously-operating roller conveyors and conveyor belts to ensure that the shafts rotate smoothly under heavy loads. Metallic pillow block bearings require external lubrication, which considerably increases the likelihood of contamination. The process of lubricating metal bearings requires additional time […]
Internal clearance in ball bearings Pt. 2
This is Part 2 of a two-part article on radial play within ball bearings. General Design Considerations: The selection of the radial play value in a specific bearing application is an important design consideration. As described previously, radial play directly affects the contact angle and axial, or end, play of the bearing. In addition, in […]
Radial play (internal clearance) in ball bearings Pt. 1
At first glance, ball bearings are relatively simple mechanisms. However, an analysis of their internal geometries reveals that they are quite complex. For example, the ball to raceway conformity, the radial play, and the number of balls all impact the ability a ball bearing to support loads under a variety of conditions. Typically, ball and […]
