Rising global energy costs and the implementation of carbon reduction strategies have prompted companies to continually look for solutions that reduce operational energy consumption, balancing economic and environmental benefits. According to a Statista survey, 54 per cent of corporate CEOs say they are already using energy-efficient appliances, technologies and equipment as part of corporate sustainability.
Based on the increasing demand for energy saving and emission reduction from industrial customers, Timken has introduced Timken® EnviroSpexxTM energy-saving roller bearings, which are engineered specifically to meet environmental goals. The series effectively reduces the amount of electricity needed to run equipment, helping customers save on energy costs while effectively Reduce carbon footprint.

Unique geometry designed to meet environmental goals
Timken® EnviroSpexx ™️ energy-saving roller bearings are designed to increase efficiency and reduce energy consumption. The unique internal geometry is designed to minimise rotational torque, thereby maximising the system efficiency of the machinery. Secondly, the reduction in bearing torque also reduces the amount of electricity required by the customer to operate the equipment or machinery, reducing overall energy consumption and carbon emissions. This ideal internal geometry also provides an optimal balance between torque and bearing fatigue life, which can extend bearing life under certain operating conditions.
Timken® EnviroSpexx ™️ bearings have been proven to run cooler than other bearings, allowing them to operate more reliably for longer periods of time, reducing carbon emissions while helping customers save on replacement and maintenance costs.
Advantages of Timken®EnviroSpexxTM Energy Efficient Roller Bearings
✓ Lower running temperatures
✓ Extended bearing life
✓ Lower total power consumption
✓ Achieve environmental goals
✓ Wide range of products
The Timken® EnviroSpexx ™️ series includes a wide range of spherical roller bearings, tapered roller bearings and housed roller bearings for a wide range of industrial applications, such as gearboxes, pumps and compressors, that can significantly reduce the carbon footprint of equipment.
Timken has conducted a series of user case studies to validate the energy savings of Timken® EnviroSpexx ™️ energy-efficient roller bearings in a variety of equipment. Next, let’s see how the use of Timken®EnviroSpexx™️ bearings can bring customers benefits compared with standardised bearings in three representative application scenarios: gearboxes, compressors and pumps.
Case Study
Case 1: Gearbox
The customer selected Timken® EnviroSpexx ™️ tapered roller bearings for their 3-axis/6-bearing gearboxes, which reduced torque by 10% and resulted in cost savings of $5,066 over five years, with a total reduction in carbon emissions of 25,398 lbs.
Case 2: Compressor
The customer’s compressor shaft is supported by two tapered roller bearings. By using Timken® EnviroSpexx ™️ energy-efficient roller bearings, the torque for this application was reduced by 25%, resulting in a total energy cost savings of $4,691 over five years and a total reduction in carbon emissions of 23,523 lbs.
Case 3: Pumps
The customer’s pump shaft is supported by two tapered roller bearings. The selection of Timken® EnviroSpexx ™️ energy-efficient roller bearings resulted in a 10% reduction in torque, a total five-year energy cost savings of US$841, and a total reduction in carbon emissions of 3,827 lbs.
As you can see, the reduction in torque of Timken® EnviroSpexx ™️ bearings translates into lower energy consumption compared to standard bearings. The Energy Saver series of bearings in a wide range of industrial equipment makes a compelling case for saving costs and achieving environmental goals. Based on the fact that most factories run dozens or even hundreds of pieces of industrial equipment at the same time, coupled with the impact of the equipment’s work cycle, energy-saving bearings, if used, will significantly reduce the energy consumption and costs of the factory. As a result, Timken recognised the importance of energy efficiency in industrial equipment decades ago and began designing energy efficient bearings.
