Prevent rolling bearing failures right from the start

Our patented oil-lubricated rolling bearings ensure continuous lubrication of your bearings and avoid downtime due to motor damage or maintenance. For more availability and long-term cost savings.

Oil-lubricated rolling bearings: the smart choice for reliability

Fast return on investment

Compared to grease-lubricated bearings, oil-lubricated rolling bearings only require relubrication every two years instead of four times a year. This means your investment pays for itself in less than a year.

Less motor failures

Over 50% of all motor failures are caused by the bearing. With oil-lubricated rolling bearings, you minimize potential sources of failure and thus reduce the risk of motor damage.

High reliability without relubrication

80% of bearing failures in grease-lubricated bearings are caused by incorrect, insufficient, or unsuitable lubrication. To help you avoid this frequent cause of failure, we’ve created a solution that makes conventional regreasing unnecessary.

How oil-lubricated rolling bearings work

The oil lubrication system includes an oil ring similar to a sleeve bearing housing, which circulates the oil and distributes it across the anti-friction bearings. As the motor shaft turns, the oil ring also rotates, picking up oil from the oil reservoir. This oil ring carries the oil upward, and gravity helps spread it over the shaft and bearings for lubrication. The bearing housing uses oil seals and gap seals to create a sealed chamber suitable for harsh, dirty, dusty outdoor environments, both hazardous and nonhazardous, with ingress protection rated up to IP56. You benefit from high reliability, less maintenance, and less potential sources of error. Watch the video to discover our technical solution in detail.

Your competitive edge with oil-lubricated bearings

Reduced maintenance effort

Oil-lubricated bearings eliminate the need for regular relubrication. Unlike grease-lubricated rolling bearings, the oil only needs to be changed every two years instead of every 1,400 to 2,500 operating hours. This significantly reduces maintenance and service costs.

Patented technology

Rely on top performance and high durability. Our unique oil lubrication system is designed to give you real competitive advantage – tried, tested and patented.

Compact design

Oil lubrication enables smarter, more compact bearing designs – ideal when every millimeter counts. You benefit from high performance with low space requirements.

Cost reduction

Unlike grease bearings, oil-lubricated rolling bearings are suitable for under-critical designs and low-speed operation. In addition, lower maintenance requirements and less unplanned downtime result in a fast return on investment and a longer service life.

Oil-lubricated rolling bearings (OLRB) significantly extend service intervals – which means less maintenance effort, fewer errors, and lower costs over time. Although oil lubricated rolling bearings may come with slightly higher initial costs, the investment typically pays for itself within just one year. Want to know how much you could save? Get in touch – our experts will be happy to calculate your potential economic benefits.

Oil-lubricated rolling bearings are stuitable for a wide range of industrial applications – especially where long service life, high reliability, or demanding operating conditions matter. They’re also fully suitable for use in Ex-protected areas. That makes them ideal for environments with strict safety standards, such as the chemical, oil & gas, or process industries. Need support with a specific application? Our team will be happy to help.

In some specific cases, a retrofit may be possible – but it depends on the specific motor design and your on-site conditions. We recommend evaluating each case individually to ensure the best technical and economic outcome. Get in touch with us for a detailed assessment – our experts will be happy to advise you.

Rolling bearings offer several key advantages over sleeve bearings. For instance, they don’t come with the same limitations on minimum speeds or critical speed ranges. That means more flexibility in your application – especially in variable-speed or stop-and-go operations.
