SKF said the MRC Marathon units incorporate lightweight and durable thermoplastic housings and have a cavity-free base so that they can be mounted flush with surfaces and gaps that could allow contaminants to collect are eliminated.
In addition, the units come with low-friction rubber seals as well as US Department of Agriculture (USDA) approved sealed-for-life lubricants “to enable virtually maintenance-free operation and promote extended service life,” added the Philadelphia-based company.
