What Shaft and Housing Fits, Tolerances and Surface Finish Does a Spherical Plain Bearing Need?
The outer ring is normally pressed into the housing (H7 only for light loads where axial movement is needed), and the inner ring is fitted to the shaft with a clearance or a light interference, depending on how the load acts. As a common starting point, one maker’s table lists an h6 hardened shaft for […]
What Causes a Spherical Plain Bearing to Squeak, Stick, Bind or Show Stick-Slip, and How Do You Fix It?
The most common cause of squeaking and jerky movement is stick-slip: the surfaces grip, then let go, then grip again, because it takes more force to start sliding than to keep sliding. A lack of lubrication, a worn-in or very smooth surface, a bearing clamped too tight, and misalignment can each make it worse. Find […]
