Extreme radial loads occur time and again in lift tables and material handling equipment. Bearings can be subjected to high pressures in clamping operations and hoisting equipment. Under such conditions external lubricants and solid lubricants can be squeezed out of metal bearings. Solid lubricant films such as PTFE or Molybdenum Disulfide can be ineffective in high load situations. J is a low-cost bearing for light loads, providing very low friction in almost any environment.
Clips have a flange on both ends, one large and one small one.
A slot across the lenght of the bearing allows it be compressed for installation.
