Luoyang,China,5 August 2025:Recently, a series of high-speed,large-size slewing bearings developed by LZJM Precision Bearingfor centrifugal casting pipe moulding machines were successfully launched and passed user acceptance inspection. This marks another crucial step forward for LZJM Precision Bearings in its research and development innovation journey.
The pipe mould series bearings typically consist of components such as rings, rolling elements, cages, seal covers, seals, and lubrication accessories. This series of bearings adopts a three-point contact ball structure, making them suitable for vertical installation and high-speed rotation conditions. The bearing rings are forged from high-quality alloy steel blanks, which undergo tempering treatment to achieve a strong and resilient base material. The raceway sections are further strengthened through medium-frequency induction hardening. Optimized raceway structure parameters, combined with high-precision steel balls, enable high load-carrying capacity. The comb-shaped retainer, made from low-friction, wear-resistant resin material, evenly separates the steel balls, ensuring smooth and stable bearing rotation performance. The seal cover plate is meticulously crafted from low-carbon, high-strength alloy steel and combined with high-quality rubber seals to create a sealed, clean bearing operating environment. Under fully clean lubrication conditions, this design ensures long-term bearing performance.
