Product Description Slim but sturdy, needle roller bearings have a thinner profile than ball bearings. They're better than other roller bearings at handling light loads at high speeds. The solid housing bolts down to support shafts as they turn. Lubricate your bearings regularly to keep them in tip-top shape. These bearings are not sealed, which may attract dust and debris in the grease. Aluminum Housing — One-third the weight of cast iron but not as strong. Aluminum also resists corrosion. Press Fit — Mount directly onto a hardened and ground shaft. Misalignment Capability — Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.
