Three-Piece Narrow Spherical Plain Bearings with Chrome Plated Heat Treated and PTFE Self-Lubrication NPB Series
PTFE Lined Type-Inch
• Race: Carbon Steel, Heat Treated, Hard Chrome Plated, Precision Ground
• Ball: 52100 Bearing Steel Heat-Treated, Hard Chrome Plated, Precision Ground
• Liner: PTFE Lined, Metal-to-Metal Optional
• Tolerance: This bearing has tighter tolerances than traditional rod end.
Rod end bearings are used on the ends of cylinders or linkages to take up misalignment between two connected parts. Both male and female configurations are available and offer optional lubricator fittings. Two-piece and four-piece Commercial and precision spherical bearings are offered as well. Spherical bearings are design to handle high radial loads.
The bearing's spherical outer housing minimizes friction and its a good solution to provide self lubrication.
