Double row external ball slewing ring<\/h1><\/div>
<\/div>

Tecma Drive’s double-row ball bearing slewing rings are designed to efficiently withstand high combined loads (axial, radial, and overturning moments). Their structure, with two parallel rows of balls, provides homogeneous load distribution and high rigidity under severe conditions.<\/p>\n

Manufactured from induction-hardened and ground 42CrMo4 steel, they offer superior precision and strength. Their modular design allows for various tooth configurations (internal, external, or toothless according to DIN 3967), specific sealing systems, and diverse mounting options.<\/p>\n<\/div>
