Spherical Plain Bearing

Link Ball

Rod End

Spherical plain bearings are self-aligning sliding bearings for heavy loads.
High resistance to impact loads makes them ideal for oscillating parts subjected to heavy loads at low speeds.
The link ball is a spherical slide bearing with ball studs that provides smooth motion down to the smallest clearance.
Suitable for link motion mechanisms in various automatic machines due to its excellent wear resistance and large oscillation angle.
Rod ends are spherical slide bearings with spherical inner rings of the same precision and hardness as steel balls for bearings.
This ensures play-free, extremely smooth rotation and oscillation.
