THK PB Standard Type Rod End

The THK PB Standard Type Rod End is a high-rigidity spherical plain bearing designed for smooth rotation and oscillation. It uses a copper alloy bush between the steel outer ring and spherical inner ring. The spherical surface is hard chrome plated to provide high wear and corrosion resistance.

The PB Series has an oil groove and lubrication hole on the outer ring. These allow grease to be replenished through the grease nipple during maintenance. This makes the PB suitable for applications that require regular lubrication.

The PB Series is available from PB5 to PB30, with inner diameters from 5 to 30 mm. Static applied radial load ranges from 7,840 N to 148,000 N, depending on the model.
