Roller Bearing Outlook 2025

Understanding the overall economy as it relates to the global bearing market is critical because it will ultimately determine how companies spend their money. In a down economy, companies go into protective mode, reducing inventories, headcount, R&D expenses and less willing to spend money on products on projects that have not turned into real purchase contracts. In a healthy economy, we see more R&D in heat treatment, lubrication, steel quality, etc. with headcount and resources willing to support long-term (and unpaid) projects.

Rolling Bearing Calculations with Considerations of Geometric Deviations

Rolling bearing calculations are usually based on the assumption of ideal nominal geometries. However, actual components and assemblies are always subject to statically distributed geometric deviations resulting from the manufacturing and assembly processes. This leads to changes in the internal geometric conditions which have an effect on bearing characteristics such as the service life. The FVA-Workbench makes it possible for users to consider these geometric deviations in bearing calculations for more reliable results.

Efficiency, Engineering & Espionage

By definition, a spherical roller bearing (SRB) is a rolling element bearing that permits rotation with low friction and permits angular misalignment. SRBs consist of spherical rolling elements, an outer ring, a cage as well as an inner ring with two raceways inclined at an angle to the bearing axis. SRB technology has landed the component in unique applications including high pressure grinding rolls (HPGRs), pipelaying ships, Ferris wheels and even a Cold War–era marine espionage mission.

Webinar: Advanced Mainshaft Bearing Solutions for Wind Turbines

Mainshaft bearings inside wind turbines are subjected to extremely harsh operating conditions that result in failure patterns which include surface-initiated fatigue, abrasive wear and uneven internal load distribution. This webinar will introduce you to the latest engineering advancements in spherical roller bearing design, including solutions that allow potentially damaging thrust to be safely transferred through the bearing to the housing support. The resulting reduction in torque, friction and heat significantly improves the overall efficiency of the system, thereby enabling the wind turbine to generate more power – more reliably!

Preventing Roller Bearing Failure

I’m building a custom gearbox with 7075 T-6 spur gears, and I’m concerned that aluminum flakes will enter the races on the roller bearings (SKF 2307) and cause premature failure. So my question is — should I place an oil seal on the shaft first to protect the bearing — or is this an unfounded concern and I should mount the seal in the typical manner outside the bearing? Or both? Or go with a sealed bearing? I’m confused and could use your expertise, please.

Dude - Where's My Preload

Many of us have been there; the bearings had the correct preload. You know it, you were there, and you personally saw the measurements. Now, the testing is done and the preload is gone. Not a little gone, not sort of gone - gone, gone. Finger pointing ensues. Suppliers are dragged in by their wrinkly Polo collars. You know the drill. Losing preload in a tapered roller bearing (TRB) system over the life of your application can be a troublesome problem, particularly for gear sets that are prone to noise or severe applications that rely on a very rigid and stable system.
