High-Carbon Chromium Steel Slewing Bearing with ISO P5 Precision Grade and 100mm

Slewing bearings are core structural components designed to simultaneously bear axial loads, radial loads and tilting moment loads, enabling smooth and precise rotational movement for heavy machinery and precision equipment. Our slewing bearings adopt advanced design and manufacturing technology, strictly following international standards and quality control systems, ensuring stable performance even in harsh working environments such as high temperature, low temperature, humidity and corrosion.

• Factory Direct Price & High Profit Margin: No middlemen, direct factory supply! We offer competitive ex-factory prices helping you reduce procurement costs and gain more price advantages in the global market. MOQ is flexible, suitable for both small-batch trial orders and large-scale bulk purchases.
• Superior Quality & Durability: Made of high-carbon chromium steel with vacuum-degassed bearing steel rings, our slewing bearings undergo precision grinding (surface roughness Ra ≤ 0.2 μm) and strict heat treatment (quenching, tempering), enhancing wear resistance and fatigue resistance significantly. The service life can reach more than 30,000 hours in normal working conditions, reducing maintenance costs for your customers.
• Multi-Type & Customization: We supply all mainstream types, including Single-Row Cross Roller Slewing Bearing, Single-Row Four-Point Contact Ball Slewing Bearing, and more. Customization is available according to your drawings, dimensions, load requirements, sealing methods and gear types (internal/external gear), perfectly matching your specific application scenarios.
• High Precision & Stable Performance: Achieving ISO P5-grade accuracy, our slewing bearings have adjustable axial clearance (0.02 - 0.05 mm) and low friction coefficient (as low as 0.0015), ensuring precise positioning and smooth rotation without jamming. They can handle combined loads efficiently, with axial load ≥ 500 kN, radial load ≥ 300 kN, and moment load ≥ 200 kN·m for standard models.
• Wide Application & Versatility: Our slewing bearings are widely used in construction machinery (excavators, cranes, concrete pump trucks), wind power (yaw and pitch systems), port machinery, mining equipment, medical imaging (CT scanners, MRI machines), industrial robots, radar systems and agricultural machinery, covering almost all fields that require rotational movement and load support.
• Professional Service & Fast Delivery: Our team of engineers with 10+ years of experience provides one-stop service, including product selection, technical consultation, custom design and after-sales support. We have a large inventory of standard models, ensuring delivery within 7-15 days; custom orders are delivered within 25-45 days, meeting your urgent delivery needs.

We are a professional slewing bearing manufacturer with advanced production equipment (CNC vertical lathes, CNC gear hobbing machines, precision grinders) and a complete quality control system (from raw material inspection to finished product testing). We have passed ISO9001, GJB9001A quality system certification, and apply  manufacturing technology to civilian products, ensuring product reliability reaches the world's advanced level. Our factory has a large production capacity, capable of meeting large-volume orders, and we provide OEM/ODM services to help you build your own brand easily.
