Crossed Roller Bearings

In a cross roller bearing, the cylindrical rollers are arranged perpendicular to each other through spacers on the rolling surfaces of the V- groove at 90°. This design enables cross roller bearings to withst and radial loads, axial loads and moment loads in all directions. At the same time, the size of the inner and outer rings is minimized, especially the ultra-thin form is a small size close to the limit, and has high rigidity, so it is suitable for the joint parts or rotating parts of industrial robots,and the rotary table of machining centers.Manipulator rotating parts, precision rotary table, medical instruments,measuring instruments, IC manufacturing equipment,etc.are widely used.

Harmonic Reducer Bearing

Harmonic reducer bearings are of crossed cylindrical roller structure, which can be divided into two categories: outer ring split, inner ring whole and outer ring and inner ring as a whole according to their application occasions. The rolling elements are cylindrical rollers, which are vertically arranged in the V-shaped raceway at 90° to each other. This structure enables a single bearing to bear loads in all directions such as axial load, radial load and overturning moment at the same time. Mounting holes are convenient for customers to install directly, and are suitable for various types of harmonic reducers.

Robot Bearing

The robot bearing is a crossed roller bearing structure. According to its application, it is divided into two categories: the outer ring split, the inner ring as a whole, and the outer ring and the inner ring as a whole. The rolling elements are cylindrical rollers, which are arranged in the V-shaped raceway at 90 degrees to each other. This structure enables a single bearing to bear loads in various aspects such as axial load, radial load and overturning moment at the same time. The bearing has high rigidity, rotation accuracy and composite bearing capacity. Installation holes are convenient for customers to install directly, suitable for various types of robots.

Wire Raceway Bearings

The rolling element spacing of the steel wire raceway bearing can be freely selected, with small installation space and high precision. The structure is simple and easy to disassemble, and it can be easily installed and used directly. The standard diameter of the raceway ring can be designed according to the actual requirements of the user. The nylon cage guided by the rolling element can be divided into several sections. Each section runs smoothly and quietly, and can also compensate for the length change caused by high temperature. Compared with traditional slewing bearings, it has decisive advantages, such as higher rotation accuracy, better corrosion resistance, higher impact load, lighter weight, less maintenance, etc.

Thin Wall Bearing

Thin-walled ring bearings of thin-walled bearings are highly accurate, very quiet and have a high load-carrying capacity. These ball bearings are available in three designs and are extremely small and mostly square in cross-section. In these series, the cross section remains the same even for larger shaft diameters and bearing bores. Mainly used in robot joint bearings, aerospace high-precision thin-walled bearings and large bearings for wind turbines and other bearings that require high precision and small space.

Slewing Bearing

The slewing bearing is composed of inner and outer rings, rolling elements, etc. It is a large bearing that can bear comprehensive loads, and can bear large axial and radial loads and overturning moments at the same time. Slewing bearing, also known as slewing bearing, is widely used in real industry. It is an important transmission component necessary for machinery that needs to perform relative rotary motion between two objects and simultaneously bear axial force, radial force and tipping moment. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, construction machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

Turntable Bearing

Turntable bearings can withstand radial loads, bidirectional axial loads and overturning moments, and are suitable for occasions with high precision and combined loads such as turntables, faceplates, milling heads and reversible fixtures. There are mounting holes on the bearing ring, which is very convenient to install. Axial and radial preload after installation ensures high precision and high rigidity. The size series is complete, and it can be used reasonably for different sizes of turntables; the appearance and installation dimensions of different series of turntable bearings are the same, which are suitable for selecting suitable series according to different environmental requirements.
