The Welded Split Oil Supply Semi-Ring is a key auxiliary component in the lubrication system of sliding bearings and thrust bearings, specially developed for white metal bearing systems that require frequent maintenance and on-site installation. This Q235 Split Oil Supply Semi-Ring for Bearings adopts a 2-piece welded split semi-circular structure, which can be installed and replaced without disassembling the entire shafting system, greatly reducing equipment downtime and maintenance difficulty. Its core function is to guide, distribute and stabilize the lubricating oil flow, ensuring that the lubricating oil continuously and evenly reaches the bearing working area, forming a reliable and stable oil film, and its structural design and installation accuracy directly affect the lubrication performance and operational reliability of the entire bearing system.
The unique split structure of this Split Oil Ring for White Metal Bearings eliminates the need to disassemble the entire shaft and bearing assembly during installation, replacement and maintenance, greatly shortening the equipment shutdown time, reducing maintenance labor costs, and adapting to the on-site maintenance needs of large industrial equipment.
Adopting ISO 3834 compliant precision welding process, the semi-ring body and support rod are firmly connected, with excellent structural strength and stability, maintaining dimensional accuracy and structural integrity under long-term dynamic load up to 25MPa, without welding fracture or deformation.
Through optimized oil circuit design, the product ensures stable oil supply under various working conditions, effectively reducing friction between the shaft and the bearing working surface, controlling bearing temperature rise, minimizing abnormal wear, and extending the service life of the bearing and the entire rotating equipment.

We select high-quality Q235 carbon structural steel as the base material, which balances excellent structural strength, welding performance and machining performance, and can adapt to the harsh working environment of industrial equipment. The machining process first completes the precision forming of the semi-ring body, ensuring that its arc size and fitting accuracy meet the design requirements; then completes the positioning and assembly of the support rod, and uses the standard precision welding process to connect the semi-ring body and the support rod. During the welding process, we strictly control the welding deformation to ensure the alignment accuracy of the oil circuit and the fitting accuracy of the split structure. After welding, 100% weld seam inspection and dimensional verification are carried out, and anti-rust or surface protection treatment is applied according to the working environment.
We can manufacture the Split Oil Supply Semi-Ring strictly according to customer drawings, or provide customized design and production according to different bearing structures, lubrication methods and installation space requirements, ensuring a good match with the bearing housing, thrust pads and other lubrication components. At the same time, we can provide a complete set of related components including thrust shafts, thrust pads, thrust pad base rings, balance blocks and bearing housings, realizing the overall coordination of the white metal bearing system in lubrication, load bearing and structure, and providing overall supporting support for the bearing and lubrication system.
All critical surfaces of the product are coated with anti-rust protective agent, wrapped with VCI anti-corrosion paper to isolate air and moisture. The paired split semi-rings are packaged in a matched way, with custom positioning blocks installed inside the package to prevent misalignment and damage to the mating surface during transportation. The product is surrounded by high-elasticity cushioning materials to absorb vibration and impact, and the outer packaging adopts reinforced export wooden cases, suitable for long-distance cross-border transportation. The packaging scheme can be adjusted according to customer requirements, destination ports and project site needs.
