Spherical roller bearings cut maintenance costs

In most cases, the sealed variant is dimensionally interchangeable with open bearings enabling applications to be upgraded simply and cost effectively.


During installation, maintenance and operation, open bearings can be exposed to contaminants, which can significantly reduce bearing service life. With sealed spherical roller bearings a high degree of cleanliness is maintained inside the bearing, to significantly increase bearing service life. In contaminated environments, sealed bearings can last up to four times as long as open spherical roller bearings.

Under certain operating conditions, sealed spherical roller bearings can be considered relubrication-free. As the bearings do not require external seals in all but the most aggressive environments, installation is simplified, further reducing downtime and maintenance costs. Additionally, the seals virtually eliminate the risk of lubricant leakage often associated with conventional open bearings and external seals, minimising environmental impact.
