Single Row Ball Slewing Bearing: Precision, Range & Support

Slewing bearings are mainly used in excavators, cranes, tower cranes and other mechanical equipment. Its core function is to support the weight of the upper structure and transmit the huge impact load generated during operation, while ensuring that the upper structure can rotate smoothly and accurately.

As a slewing bearings manufacturer, let me introduce the product features of our single row ball slewing bearing.

product advantages and selling points

High precision product parts

We are constantly introducing the latest CNC machines for one purpose: to ensure micron-level accuracy.

Repeatable tolerances of up to ± 0.01mm are essential to ensure perfect geometric consistency for each batch and size of product. It is important to know that accuracy is the lifeline of bearing life and running stability.

Full model of the product category

Our slewing ring bearing range from 315.20 (small diameter, light load) to 2500.60 (large diameter, heavy load) of various standard and non-standard models.

This is not only a list of numbers, but also means that whether you need precision bearings for small automation equipment or stable support for heavy construction machinery, we can quickly find the most suitable choice for you in the existing product line, greatly shortening the selection and procurement cycle of customers.

International quality certification

The standard certification system is the framework and foundation of our quality commitment. Our products comply with the globally recognized ISO 9001 standards and are strictly controlled in every aspect of the production process, with continuous improvement at every stage of production.

Twenty years of professional experience

We have 20 years of professional experience, professional technical knowledge and mature program design is precipitated by time.

Twenty years in the industry, we have solved almost all known and unknown slewing bearing application problems, and our deep technical accumulation is our strongest backing.

Strict internal quality control

From raw material inspection to final assembly, our quality inspection is multi-level to ensure accuracy and durability in accordance with all industry specifications.

Product structure

The single-ball slewing bearing has a simple structure and is mainly composed of inner and outer rings, steel balls and isolation blocks.

We usually use high-strength alloy structural steel (such as 42CrMo or 50Mn) as the ring material, which is the basis for ensuring the bearing capacity.

The raceway part must be induction hardened to achieve the necessary hardness (usually HRC 55-62) and wear resistance, while the ring body maintains a certain degree of toughness to prevent brittle fracture.

Application scenarios

Construction machinery and construction equipment:

Small and medium-sized cranes, tower cranes, wheeled excavators are the main application of single volleyball support. Crane slewing bearing and excavator slewing bearing can effectively bear the axial force, radial force and overturning moment at the same time.

These equipment often need to carry out large angle, heavy load amplitude, the bearing of the composite carrying capacity and impact resistance performance requirements are very high.

Industrial automation and special equipment:

In automated production lines, elevated storage systems, CNC machine tool positioning turntables, and various types of welding positioner, single-row ball bearings are also promising.

These scenarios require high positioning repeatability and smooth operation. Through the strict control of the tooth profile accuracy, we ensure that the bearing can still maintain the transmission accuracy and low noise in the case of frequent start and stop.

Service and Assurance

Pre-sales services:

We have a professional team composed of senior engineers. They not only have deep accumulation in the field of slewing bearing technology, but also have rich experience in export business.

This means that we can understand the diversified needs of global customers, and can provide the most accurate and economical design suggestions and product selection guidance according to your specific working conditions, load requirements and installation environment from a professional perspective.

After-sales service:

After the product is delivered, our responsibility does not end.

We promise to respond to any feedback on product quality within 24 hours. If there is a quality problem after assessment, we will not only re-send qualified products for compensation, but also analyze the reasons in depth to ensure that such problems do not happen again.

Although we have a strict quality control system, the probability of quality problems is extremely low. But we always take a responsible attitude to deal with all after-sales matters, put the interests of customers first.
