Introducing our premium Cross Roller Slewing Bearing with a 1.5 meter outer diameter, manufactured from high-grade quenched and tempered steel. As a factory-direct manufacturer, Henan San Kuang Machinery Technology Co., Ltd. combines over 3 years of specialized experience (founded 2022) with a state-of-the-art 10,000-30,000 sqm facility to deliver bearings that meet rigorous international standards. Every bearing comes with a Mill Test Report guaranteeing material traceability and mechanical properties. Our cross roller design ensures high load capacity, rigidity, and smooth rotation – ideal for demanding applications such as crane turntables, excavator swing gears, large rotating platforms, and wind energy equipment. We ship globally from major Chinese ports (Shanghai, Lianyungang, Qingdao, Tianjin) to markets across North America, Europe, Asia, Africa, and Oceania.
Product Features & Technical Specifications
- Cross Roller Design: Cylindrical rollers arranged at 90° alternating angles provide high load-bearing capacity in axial, radial, and moment load directions, minimizing clearance and maximizing rigidity.
- 1.5m Outer Diameter: Optimized for medium-to-large equipment requiring a compact but robust rotating interface. Custom sizes available upon request.
- Quenched and Tempered Steel: Made from forged or rolled alloy steel (e.g., 42CrMo4) with a hardness of 240-280 HB, ensuring excellent wear resistance and structural integrity under heavy cyclic loads.
- Mill Test Report Included: Each bearing is supplied with a comprehensive MTC that documents chemical composition, mechanical properties, heat treatment parameters, and non-destructive testing results.
- Integrated Gear Option: Internal or external spur gears can be machined directly onto the bearing race, eliminating the need for separate ring gears and reducing assembly complexity.
- Sealing & Lubrication: Standard dual-lip rubber seals protect against dust and moisture. Provision for grease nipples allows easy maintenance. Custom seals (e.g., high temperature) available.
- Precision Grades: Standard running accuracy per ISO 281 (P0). Higher precision (P5, P6) achievable with additional machining – please consult our engineers.
- Long Service Life: Proper heat treatment and raceway hardening (induction or flame hardening optional) extend fatigue life significantly. Typical design life exceeds 3,000 hours under rated load.

Why Choose Our Cross Roller Slewing Bearing?
- Enhanced Durability: Quenching and tempering refines the steel microstructure, yielding consistent hardness and toughness – essential for shock loads in slewing rings.
- Reliable Documentation: The Mill Test Report provides full traceability: chemical composition (C, Si, Mn, P, S, Cr, Mo), tensile strength, yield strength, elongation, and impact test values.
- Customizable Design: We accommodate non-standard hole patterns, gear specifications, mounting configurations, and special surface treatments (e.g., phosphating, zinc plating).
- Cost-Effective Manufacturing: As a direct manufacturer with 51-100 skilled employees and modern CNC equipment, we offer competitive pricing without sacrificing quality.
- Global Shipping Experience: Annual export value of US$2.5M–5M across 14+ markets ensures safe packaging and timely delivery via major ports.

Frequently Asked Questions (FAQ)
-
What is the lead time for a standard 1.5m cross roller slewing bearing?
Typical lead time is 30-45 working days for standard designs. Custom gear or precision grades may add 10-15 days. We can expedite urgent orders – please inquire. -
Can the bearing be supplied without gear?
Yes, the bearing can be made without gear teeth (plain raceway). This is common for applications where external drive systems are used. -
Do you provide installation guidance?
Absolutely. We offer a detailed installation manual with each bearing, including torque specifications for mounting bolts, runout tolerances, and recommended lubrication schedules. -
How is the Mill Test Report structured?
The MTC follows EN 10204 Type 3.1 format, listing steel grade, heat number, ladle analysis, mechanical test results (yield, tensile, elongation, reduction of area), and hardness readings. Non-destructive test results (ultrasonic, magnetic particle) are included if requested. -
What maintenance is required?
Regular regreasing every 500 operating hours or monthly, whichever comes first. Inspect seals for damage and check bolt torque annually. For harsh environments, more frequent lubrication is recommended. -
Can the bearing be repaired if damaged?
In most cases, raceway damage can be repaired by grinding and oversize rollers. However, wear beyond the hardened layer requires replacement. Our after-sales team can evaluate and suggest the best solution. -
How do you ensure quality control?
Every bearing undergoes 100% inspection of dimensions, hardness, and magnetic particle inspection of critical surfaces. We also perform a running test on a rotation fixture to verify smoothness and noise level. -
Do you offer samples for testing?
Yes, we can supply small quantities (1-2 pieces) for validation. Sample cost is negotiable and will be deducted from bulk orders. Shipping is FOB from any of our port options.
