Max. permissible speed : This is affected by the bearing load, the bearing clearance, the lubricant and heat output and input. The maximum permissible speed given in the tables applies for apurely radial load, normal bearing clearance toleran- ce, no external heat, an operating temperature which is not above the limit, and a low and absolutely shock-free load.
Cabricating nipple : DIN 71412
Load ratings : Calculated acc. to DIN ISO 76 and 281
Note : With these rod ends, it is important to ensure that the tilt angle specified in the table it not exceeded, either while mounting or during operation, otherwise the sealing washers may be damaged.

Special versions:    

  • full completement (without retainer)
  • sealing washer made of synthetic rubber-metal compound Further versions are available on request.
