Double row external ball slewing ring

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.

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.

Two independent rows of balls with four-point contact each, compact design, hardened and ground 42CrMo4 steel material, double lip seal, lubrication by radial grease fittings and adaptable mounting with through or threaded holes.

Tower and mobile cranes, telescopic platforms, mining and tunneling machinery, heavy load handling and offshore rotating platforms.

Tecma Drive’s comprehensive manufacturing: Design, machining and thorough in-house control, guaranteeing reliable and durable solutions for advanced engineering.
