What‘s the characteristic of Split needle roller bearings cage?

The cage of Split needle roller bearings partially wraps all or part of the rolling elements and moves the bearing parts to isolate the rolling elements and usually guide the rolling elements and keep them in the bearing.
When the shaft and the bearing housing can be used as a raceway surface, it can be used as a set of independent bearing components. Split needle roller bearings have a small cross-section but a high load capacity, so they are very suitable for bearing configurations with limited radial space.

Split needle roller bearings have a relatively high section height and a relatively high load carrying capacity. General purpose needle retaining type bearing is a kind of bearing that has excellent performance under high rotation. The needle roller is guided correctly by a special shape with high rigidity and precision, and the dimensional error is extremely low. They have the characteristics of considerable lubricant capacity, light weight and high rigidity, and can be used under severe conditions: such as high speed, impact load, etc., so they can be used in a wide range. Generally used in gearboxes and engine connecting rods of automobiles, tractors, and construction machinery;

Split needle roller bearings The main function of the cage is to separate the rolling elements at equal distances and evenly distribute them on the circumference of the raceway to prevent collision and friction between the rolling elements during work; guide and drive the rolling elements to roll on the correct raceway; In separable bearings, the rolling elements are combined with a ferrule to prevent the rolling elements from falling off.

The cage of Split needle roller bearings has a variety of structural types and complex shapes. There are many equidistant pockets on the cage of Split needle roller bearings . Sometimes called windows for rolling bearings, they are used to isolate and guide the rolling elements. The pockets have spherical, circular, elliptical, rectangular and tooth shapes, and the size is larger than For the size of the rolling elements, the difference between the two is the pocket gap. The pocket gap allows the cage to have a certain amount of movement in the radial and axial directions. The total amount of movement in the radial direction is called the cage gap. The connecting part between the windows of the roller cage is called a lintel, which plays a role in connecting and increasing the strength of the cage.
