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 … [Read more...]
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 … [Read more...]
Rotary bearings: Answers to common questions
Bearings are internal machine components that are crucial to motion applications. They reduce friction between moving parts by giving a surface something on which to roll rather than slide. Rotary bearings consist of smooth rollers or metal balls and … [Read more...]
Schaeffler rotor bearings for wind turbines
All the forces from the wind act directly on the rotor bearing support in a wind turbine and the rolling bearings are therefore subjected to highly dynamic loads and operating conditions. A range of powertrain designs have established themselves on … [Read more...]
Part 1: Timken and Robbins team up for Ohio tunnel project
By Mike Santora Timken and Robbins are collaborating on the tunnel boring machine set to carve a path for the Ohio Canal Interceptor Tunnel in Akron, OH. In this first installment of a two part story, we interviewed the principle engineers on the … [Read more...]

Tapered roller bearings from Ritbearing
Tapered Roller Bearings Tapered roller bearings are built to thrive in demanding environments. Tapered roller bearings are designed with an outer raceway that’s tapered off like a segment of a cone. This shape prevents bearing slippage and allows … [Read more...]
How are integrated bearing assemblies being used in wind turbines?
There has been a trend in the design of wind turbine gearboxes toward using integrated planet bearings with both Cylindrical Roller Bearings (CRBs) and Tapered Roller Bearings (TRBs). The integrated bearing concept reduces the total number of … [Read more...]
What do you know about Tapered Roller Bearings?
Tapered roller bearings feature tapered inner and outer ring raceways with tapered rollers arranged between them, angled so the surface of the rollers converge at the axis of the bearing. These bearings are unique in that, unlike most bearings that … [Read more...]
