THK RE crossed roller bearing feature:

1.RE crossed roller bearing is an innovative bearing based on the design of the RB standard type bearing.The structure of RE crossed roller bearing is that the inner ring is a split type, and the outer ring is an integral design, which is suitable for a portion requiring high rotation precision of the outer ring.

2. With excellent rotation precision, the internal structure of the crossed roller bearing adopts rollers 90° perpendicular to each other (this is the reason why called the crossed roller bearing), and cages are arranged between the rollers. Prevents the rollers from rubbing against each other, effectively preventing the increase of the rotational torque. The design of this cross cylindrical roller bearing is very useful. there will be no contact or locking phenomenon of the roller. because the inner and outer rings of the standard cross roller bearing are divided structures, the clearance can be adjusted. even under high pressure, high-precision rotary motion can also be obtained.

3. Operation and installation The simplified standard cross-roller bearing is divided into two parts of the outer ring and the inner ring. After the rollers and the cages are installed, they are fixed together. The mounting bolts and the fixing flange can be finely adjusted during installation to achieve the ideal load condition, so the installation is very simple.

4. Withstand large loads. Because the rollers are vertically aligned with each other through the spacers on the 90° V-groove rolling surface, this design allows the crossed roller bearings to withstand large Loads in all directions

DK bearing THK type RE40040 Crossed  Roller Bearing provides high and stable running accuracy, suited for precision detecting instrument, robot joints, direct drive torque motor, high-precision turntable.
