Single Row Slewing Bearing: High-Precision Rotary Solutions for Heavy-Duty Applications
As a premier manufacturer specializing in rotary transmission components, ZZ Bearing delivers industry-leading Single Row Slewing Bearings engineered for exceptional performance in demanding environments. Often referred to as a "machine joint," our single row slewing ring bearing is designed to simultaneously accommodate axial loads, radial loads, and tilting moments. With a compact structure and lightweight design, these bearings are the optimal choice for applications requiring precise rotational movement without compromising structural integrity.
Unmatched Performance and Quality Assurance
Our manufacturing philosophy centers on durability and precision. The single row four-point contact ball slewing bearing is constructed using high-strength alloy steel, ensuring robust resistance against wear and fatigue.
-
Advanced Heat Treatment: We utilize precise medium-frequency quenching technology. The raceway hardness is strictly controlled between HRC55~62, providing superior surface durability and extending service life.
-
Precision Engineering: By employing digital control technologies, we maintain tight tolerances on all parts, ensuring smooth rotation and minimal friction torque.
-
Sealed for Protection: Equipped with high-quality rubber sealing strips, our bearings effectively prevent the ingress of dust and debris while retaining lubrication, making them suitable for harsh outdoor conditions.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a single row and a double row slewing bearing?
A single row slewing bearing typically features a compact design with two raceways (inner and outer rings) and is lighter in weight. It is ideal for applications with moderate loads. Double row bearings generally offer higher load capacities but are larger and heavier.
Q2: Can you manufacture bearings with specific gear teeth requirements?
Yes, we specialize in custom gearing. Whether you require external or internal teeth with specific modules, we can machine and heat-treat the gears to your exact specifications.
Q3: How do you ensure the longevity of the bearing?
We use high-grade alloy steel and advanced induction hardening to ensure the raceway hardness reaches HRC55-62. Additionally, proper lubrication and our protective sealing strips play a vital role in preventing premature wear.
Q4: Do you provide installation support?
Yes, we provide detailed installation manuals and can offer video guidance. Our bearings come with installation holes (tapped or through holes) designed for easy mounting.
