Composite roller bearing, also known as composite roller bearing, is a fully loaded cylindrical roller bearing used in forklift gantry, mobile handling and lifting systems. It simplifies the structure and saves installation space through the combination design of radial and axial bearings. Its shaft head can be directly welded to the equipment board hole, with the characteristic of replaceable accessories, suitable for cylindrical or curved raceway application scenarios.
The outer ring of the bearing adopts a thick walled fully loaded cylindrical roller design, with the main roller bearing vertical loads and the side rollers bearing horizontal loads, both made of wear-resistant and corrosion-resistant materials. The sealed structure is equipped with lubricating grease to support maintenance free operation, and lubrication channels can be added in harsh working conditions. The product includes two types: adjustable and non adjustable: the former adjusts the height through gears or nuts, while the latter uses a fixed core shaft to adapt to precision equipment. The types include RSTO (high-speed), NATR (heavy-duty), KRV (fully loaded needle rollers), etc. The materials used are high-quality bearing steel (hardness 58-62HRC) or alloy structural steel, meeting different load and speed requirements
