In the field of high-speed development of construction machinery, the stability and reliability of equipment performance is the key to determine the success or failure of the project. As a core component of the industry, the quality of the slewing bearing directly affects the operating efficiency and service life of the machinery. We specialize in providing high-quality, high-performance slewing bearing solutions for various types of construction machinery, helping your equipment still perform well under severe working conditions.
Based on the above user needs, as a professional slewing bearing manufacturer, PRISON provides industry users with comprehensive slewing bearing solutions, optimizing the whole process from design, manufacturing, installation and maintenance, in order to enhance the stability of the equipment, improve the rotary accuracy, reduce the downtime rate, and provide tailor-made mechanical core components for the construction machinery OEM.
We use high-quality raw materials and advanced manufacturing processes to ensure that each slewing bearing has the following characteristics:
High load carrying capacity: able to withstand huge axial force, radial force and tilting moment, ensuring the safety and reliability of the equipment during heavy-duty operation.
Long service life: Precise heat treatment and lubrication technology effectively reduces wear and prolongs the service life of the bearings and reduces downtime for maintenance.
High sealing performance: Unique sealing structure design effectively prevents dust, moisture and foreign matter from entering and protects the internal raceway, which is especially suitable for dusty construction machinery working environment.
Our slewing bearings are widely used in all kinds of mainstream construction machinery, and are the ideal choice for the following equipment:
Excavators: We provide high-strength and high-precision excavator slewing bearings to ensure smooth rotation and precise operation of the bucket.
Crane/Tower Crane: For the high requirements of lifting equipment, we provide crane slewing bearings with strong load carrying capacity and stable operation to ensure the safety of lifting operations.
Concrete Pump Truck: Our concrete pump truck slewing bearings can withstand the complex loads brought about by boom expansion and rotation, ensuring the stability of pumping operations.
Shield machine: We provide customized oversized diameter slewing bearings for large shield machines to ensure their stability and reliability during underground excavation.
We understand that every construction machinery project has its uniqueness. Therefore, we not only provide standardized products, but also customized services. Our technical team will work closely with you to customize the most suitable slewing bearing for you according to your equipment design drawings, working environment and load requirements. From material selection to structural design, we ensure that the final product is perfectly suited to your needs and maximizes the performance of your equipment.
