Cylindrical roller and raceway are in line contact, radial load capacity is large, both for bearing heavy loads and impact loads, also suitable for high speed rotation. Cylindrical roller bearings raceway and rolling body geometry after improving the design, has a high load carrying capacity, retaining edge and roller end face of the new structural design
LEARN MORE
The needle roller and cage assembly is a self-contained bearing element in which each needle roller is precisely guided and retained by a cage. It realizes a bearing design with high load capacity and rigidity in minimum space. The two guiding surfaces of the cage are widely spaced. This ensures precise guidance of the needle roller and cage assembly.
LEARN MORE
Axial needle roller bearings or axial cylindrical roller bearings are configured with a cage of needle rollers (rollers) between a set of raceway washers, the cage reliably guides and centers a large number of rolling elements, and there are only minor differences in the rolling elements in the same assembly
LEARN MORE
Heavy Duty needle roller bearing is a bearing unit consisting of machined outer ring, needle rollers, cage and separable inner ring, which is a kind of bearing with small section height and large load carrying capacity, specifically NK, NKS, RNA48
LEARN MORE
The inner ring and outer ring of the bearing are important components of the bearing, and their role is to ensure the normal operation of the bearing. The relationship between the inner ring and outer ring determines the rotation accuracy and life of the bearing. Therefore, when using bearings
LEARN MORE
Drawn cup needle roller bearings (with cage type and full complement needle roller type) have special outer ring structure and are a type of rolling bearings with many special features, which include
LEARN MORE
Drawn cup needle roller bearings with a drawn thin-walled outer ring, drawn cup needle roller bearings are often used in applications are commonly used in applications where the bearing seat hole cannot be used as a raceway for the needle roller and cage assembly, but requires a very compact and economical bearing configuration
LEARN MOREThe company has established a professional technical team, excellent production and testing equipment. These provide customers with perfect solutions and meet customers' demands for product reliability, stability and high quality, create maximum value for customers.
LEARN MORE
When the bearing is rotating, the free vibration of the cage and its impact with the rolling element or the ring will cause noise.
LEARN MORE
Grinding is a common method of metal cutting in the machinery manufacturing industry, and is also widely used in the bearing processing industry. The bearing parts quenched by heat treatment may have a network of cracks or more regular arrangement of fine cracks during grinding, which is called grinding cracks.
LEARN MORE
Super precision process is not only used in the bearing industry, but also very much used in the engine, and other precision machinery and instruments have also begun to use this process.
