What are the Technical Requirements for High-Speed Slewing Bearings?

The client involved in this collaboration is a renowned European manufacturer of food packaging equipment. Specializing in the R&D and production of high-speed automated packaging lines, their products are exported to over 50 countries and regions worldwide. Consequently, they impose extremely stringent requirements regarding the performance, stability, and service life of core components—particularly for high-speed rotating parts—setting industry-leading standards across four key metrics: precision, wear resistance, high-temperature resistance, and low noise levels.

1.1 Core Operating Conditions and Technical Pain Points

The high-speed slewing bearings procured by the client for this project are deployed at the core rotating station of their new generation of high-speed food packaging lines. The specific operating conditions and technical requirements are outlined below:

Operating Speed: Maximum rotational speed of 45 RPM; continuous, uninterrupted operation for 24 hours a day; annual operating duration exceeding 8,000 hours.

Load-Bearing Requirements: Must simultaneously withstand axial loads, radial loads, and overturning moments; rated dynamic load ≥ 120 kN; rated static load ≥ 280 kN.

Precision Standards: Bearing rotational precision ≤ 0.02 mm; face run-out ≤ 0.03 mm; gear tooth precision meeting ISO Class 5 standards.

Environmental Requirements: Operating ambient temperature range of -20°C to 80°C; must possess dust-proof, corrosion-resistant, and high-temperature-resistant properties; must comply with the clean production standards of the food industry.

Service Life Requirements: Under rated operating conditions, the bearing service life must be ≥ 50,000 hours, with a maintenance-free interval of ≥ 20,000 hours.

Additional Requirements: Low-noise operation (noise level ≤ 60 dB); ease of installation; support for customized dimensions; and a short delivery lead time.

Previously, the high-speed turntable bearings integrated into the client's production lines relied heavily on top-tier international brands. However, practical application gradually exposed three major pain points: First, high costs—the procurement costs for imported bearings, coupled with high subsequent maintenance expenses, significantly increased the overall capital investment for the production lines. Second, long delivery lead times—the lead time for customized products often stretched to 3–6 months, hindering plans for production line upgrades and capacity expansion. Third, slow after-sales response—due to the geographical distance of the international brands' support teams, the response time for troubleshooting and repairs was prolonged, frequently resulting in extended production line downtime and causing substantial economic losses.

LTZC High-Speed Bearing Solutions

1. High-Precision Raceway Machining

During high-speed operation, raceway precision directly determines bearing stability. LTZC employs precision CNC grinding to finish raceways, effectively controlling rotational runout, high-speed noise, and temperature rise issues, thereby ensuring that equipment maintains stable precision even under high-speed operating conditions.

2. Low-Friction, High-Speed Structure

Specifically for high-speed equipment, LTZC has optimized the internal bearing structure—including the arrangement of rolling elements, specialized cages, and lubrication systems—to achieve lower starting torque and smoother operation under high-speed working conditions. For high-speed rotary table equipment in the packaging industry, this enables long-term, continuous high-speed operation.

3. High-Speed Cross-Roller Bearings

For high-precision, high-speed equipment, LTZC recommends Cross Cylindrical Roller Slewing Bearings. These bearings feature high rigidity, exceptional rotational precision, low friction, and minimal vibration, making them ideally suited for applications such as blow molding machines, filling machines, and similar equipment.

4. High-Speed Lubrication Systems

High-speed bearings require the use of greases suitable for high-temperature environments. Additionally, LTZC incorporates automated lubrication system designs to reduce frictional heat, prevent grease loss, extend maintenance intervals, and enhance overall equipment stability—making them ideal for high-frequency, continuous production lines.
