When selecting a slew ring for filling equipment, standard off-the-shelf bearings often fall short. Filling machines operate in environments characterized by frequent start-stop cycles, moderate to high radial and axial loads, and the critical need for minimal rotational play. Our precision slewing bearings are manufactured with these exact parameters in mind.

Constructed from high-grade alloy steel (typically 42CrMo4 or 50Mn), each unit undergoes rigorous heat treatment and induction hardening on the raceways to ensure exceptional wear resistance. Unlike general-purpose turntable bearings, our units designed for packaging machinery feature optimized internal geometry. This design reduces friction coefficients, allowing for smoother rotation at variable speeds—a crucial factor when synchronizing with servo motors in multi-head filling lines.

We understand that hygiene and contamination control are paramount, especially in food and beverage or pharmaceutical applications. Therefore, our food-grade slewing rings can be supplied with specialized sealing configurations (double-lip seals or labyrinth seals) that prevent ingress of washdown water, cleaning agents, or product spillage. For cleanroom environments, we offer low-particulate generation designs that meet strict regulatory standards.

• Single Row Four-Point Contact Ball Bearings: Ideal for lighter to medium-duty filling heads where space is constrained but high rigidity is required. These offer a great balance of axial and radial load capacity in a slim profile.
  
• Double Row Ball Slewing Rings: Designed for heavier applications such as large rotary indexing tables carrying multiple filled containers. The double row configuration provides superior moment load resistance, ensuring stability even when the center of gravity shifts during high-speed rotation.
  
• Crossed Roller Slewing Bearings: For applications demanding the highest precision and stiffness, such as aseptic filling lines. The linear contact of the rollers offers greater load capacity and lower deformation compared to ball bearings, making them perfect for heavy-duty, high-accuracy tasks.
  
• Thin Section Ball Bearings: Specifically engineered for robotic arms used in secondary packaging or palletizing adjacent to filling lines. Their ultra-thin cross-section allows for integration directly into joint assemblies.
