Timken® Self-Aligning Tapered Roller Bearing Mounted Bearings are designed for applications from aggregate and steel to mining and power generation. The heavy duty housing and cartridge are made from cast steel to stand up to the harshest conditions, and are designed to accept +/-4 degrees of misalignment.. Metric sizes also are available in shaft diameters ranging from 35 mm to 125 mm.

Open and Closed end covers available for purchase.

  • 1 Permissible axial displacement from normal position of one bearing ring in relation to the other.
  • 2 C90 is the Dynamic Load Rating based on a rated Life of 90 million revolutions (3000 hrs at 500 RPM).
  • 3 Fa-max is based on the limits of the holding force of two properly tightened collars and set screws. Fifty percent of the values should be used when a single collar is installed.
  • 4 If the application loads approach or exceed Fr-max, the shaft fit should be adjusted to a line-to-line (g6 or h6) or light press fit (m6).
  • 5 Timken Double Lip Seal
