Description:
Double row angular contact ball bearing 256706, like all others of this design, is used to absorb loads, both radial and axial Considering that it is two-row, it is able to perceive axial loads in both directions. The bearing is closed, the lubricant is already added to it at the factory (its type is deciphered in the marking with a number after the letter C, usually it is lithol).The additional suffix E indicates a cage made of plastic materials. Accuracy class - 6 (increased).
The marking of this spare part and its decoding correspond to the standards in force in the post-Soviet space. Factory designation 256706 C17 can be expanded as follows:
25 - version (double row with contact seals);6 - angular contact ball bearing; 7 - a series of outer diameters;
06 - coding of internal size (d / 5); C17 - grease (Litol-24).
The maximum permissible rotation speed of the ball bearing article 256706 is 6,500 revolutions per minute. Loading capacity in statics - 25.9 kN, in dynamics - 30.1 kN.
