Double-row toothless 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.

Dos hileras independientes de bolas con contacto de cuatro puntos cada una, diseño compacto, material de acero 42CrMo4 templado y rectificado, sellado doble labio, lubricación mediante engrasadores radiales y montaje adaptable con orificios pasantes o roscados.

Grúas torre y móviles, plataformas telescópicas, maquinaria para minería y túneles, manipulación de cargas pesadas y plataformas giratorias off-shore.

Fabricación integral Tecma Drive: Diseño, mecanizado y control exhaustivo interno, garantizando soluciones fiables y duraderas para ingeniería avanzada.
