R&P Knowledge Hub

8,000 lb Dexter idler hubs used in disc brake systems are typically configured for oil bath lubrication rather than grease. Oil bath hubs require the correct oil seal and threaded oil cap to maintain proper lubrication and cooling. Always confirm spindle dimensions, bearing numbers, and cap size before ordering, as 8K hubs are not interchangeable with 7K or 9K configurations.
