McGill GUIDEROL® machined race full complement needle bearings are manufactured from bearing quality steel. The unique roller and race design provide center-guided rolling elements for higher radial load capacity. It is also well-suited for oscillating applications. GUIDEROL® bearings are constructed with a radial lubrication hole and a groove on the outer raceway. We also offer an optional inner raceway (MI-series) for relubrication through the housing or shaft. Other options include a variety of seal configurations to either help prevent contaminate entry or contain the lubricant. Depending on your preference, these bearings are available in a wide variety of sizes and options.
