Rolling Bearings from BigWings
Rolling bearings are machine elements that enable a rotary motion and absorb loads between rotating and stationary parts of machines. They absorb radial, axial or both forces depending on the design. The rolling elements minimize friction during rotation due to the small contact surfaces of the rolling bodies between the inner and outer ring.
Under the PCG® brand, BigWings Tech manufactures a wide range of rolling bearing types such as:
· tapered
· cylindrical
· spherical
Our competence in the field of design, development and production of rolling bearings is based on tradition and experience in the bearing industry. To be able to meet the requirements of the market, we are continuously developing our product range. If you have a question or special request, please contact us here.
Our products:
Perfect for transmitting and absorbing heavy radial loads / radial forces
Can absorb large radial loads and the effects of the axial load in both directions simultaneously
How are our rolling bearings designed? The right selection of materials matters!
In our production process, we source high-quality materials from trusted manufacturers and strictly follow quality standards.
We produce the main components—bearing rings, roller elements, and cages—in our own facilities. This allows us to closely monitor and ensure the quality of our products at every stage. The machining of components varies based on their shape, materials, and required properties. Our entire design, development, and production process is managed under a certified quality management system in line with ISO 9001:2015. We also keep detailed records of each production and control step for future reference.
To ensure the bearing’s final performance and reliability throughout its service life, choosing the right materials for each component and the proper heat treatment method is crucial. As the demand for larger rolling bearings grows, efficient production becomes increasingly important. We take pride in offering our customers a wide range of traditional and innovative heat treatment methods, including a patented inductive hardening process that eliminates soft spots.
Quality Assurance and shipping of a slewing bearing
The final inspection of the completed product is conducted internally by our certified quality assurance department, or in collaboration with the customer and/or a designated third party. During this inspection, the functionality and geometry of the product are thoroughly examined. The inspection is based on the specifications agreed upon during the design phase or those outlined in the contract. The results are documented in a written test report and included in the QA documentation, the scope of which is determined in advance with the customer.
Once the final inspection is completed, the slewing ring is prepared for packaging by our logistics department and made ready for shipment. The transport may be arranged directly to the construction site or initially to a seaport or airport. If standard transportation methods are not feasible, special trucks, ships, or aircraft are utilized.
