Customized Slewing Bearing – Direct Factory Price, 1-Year Warranty, Free Replacement for Manufacturing Defects
Welcome to Henan San Kuang Machinery Technology Co., Ltd., a professional manufacturer established in 2022 with a modern factory spanning 10,000–30,000 square meters. We specialize in producing high-quality slewing bearings that meet diverse industrial needs. Our customized slewing bearing offers precise engineering, robust load capacity, and the flexibility to adapt to your exact specifications—all at a direct factory price that eliminates middleman costs. With a dedicated team of 51–100 employees and an annual export value of US$2.5–5 million, we serve markets across North America, South America, Europe, Southeast Asia, Africa, and beyond. This product is backed by a 1-year warranty and free replacement for any manufacturing defects, ensuring your investment is protected.
Our slewing bearings are designed to provide smooth rotation and dependable support for heavy loads in applications such as excavators, cranes, wind turbines, robotic arms, port machinery, and more. Each bearing is manufactured under strict quality control procedures, from raw material selection to final inspection. We understand that every project has unique requirements, so we offer extensive customization options—including size, load rating, gear configuration, sealing type, and surface treatment—to deliver the perfect fit for your equipment.
Key Features & Technical Specifications
- Customizable Dimensions: Outer diameter from 200 mm to 5000 mm, with custom bore sizes and overall height available upon request.
- High-Strength Materials: Standard options include 50Mn and 42CrMo steel, heat-treated to enhance hardness and wear resistance. Alternative materials can be specified for special environments.
- Multiple Bearing Types: Choose from single-row four-point contact ball bearings, double-row ball bearings, crossed cylindrical roller bearings, or three-row roller bearings, depending on load and rigidity needs.
- Precision Tolerances: Standard precision grades P6 and P5 are available, with higher precision (P4 or customized) achievable for demanding applications like aerospace or precision robotics.
- Gear Integration: Internal or external spur gears can be machined directly onto the bearing raceway, or the bearing can be supplied without gear for separate drive systems. Gear teeth are case-hardened for durability.
- Sealing & Lubrication: Rubber seals (NBR) provide excellent dust and moisture resistance; metal labyrinths are optional for high-temperature or heavy-contamination environments. Pre-greased with lithium-based grease or specify your preferred lubricant.
- Surface Finish: Standard phosphating coating for corrosion resistance; painting (according to RAL) or zinc plating available on request.
- Load Capacity: Dynamic and static load ratings are calculated based on the specific geometry and material. Our engineering team can optimize the design for maximum capacity within your size constraints.

Frequently Asked Questions
-
What is the minimum order quantity for customized slewing bearings?
We accept single-unit orders for custom sizes. However, pricing for one piece is higher than for batch orders. For quantities above 10 units, we offer volume discounts. Please contact us for a quote. -
How long does it take to produce a custom slewing bearing?
Lead time typically ranges from 20 to 45 working days, depending on the complexity and current workload. Urgent orders can be expedited at extra cost. -
Can I get a sample before placing a bulk order?
Yes, sample orders are welcome. We can produce a single custom bearing for testing. The sample cost is deducted from the first bulk order if you proceed. -
What materials do you use? Can I specify my own material?
Standard materials are 50Mn steel and 42CrMo alloy steel. You can also specify other grades like 40Cr, 35SiMn, or stainless steel (2Cr13, etc.). Contact our engineering team for feasibility. -
Do you provide design support? I only have rough dimensions and load requirements.
Absolutely. Our engineers can help design the optimal slewing bearing based on your load, speed, mounting arrangement, and environmental conditions. Just provide your application details. -
What is the warranty coverage exactly?
The 1-year warranty covers manufacturing defects such as material flaws, raceway spalling, weld failures, or gear teeth breakage due to poor heat treatment. It does not cover damage caused by improper installation, exceeding rated loads, or lack of lubrication. -
How do you ship the bearings?
Bearings are securely packed in wooden crates with foam padding to prevent movement. We ship via sea freight (FOB Shanghai, Lianyungang, Qingdao, or Tianjin) or air freight if urgency requires. We also arrange door-to-door delivery for larger orders. -
Can I customize the sealing system for harsh environments like offshore or desert?
Yes. We offer metal labyrinth seals, double-lip rubber seals, and special high-temperature or chemical-resistant seals. Please specify your working conditions when ordering.
