Manufacturers specializing in the production of crossed roller bearings | PRS

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.

A robot bearing is a component that allows for relative motion between two parts while supporting a load. It is used to support and guide the moving parts of a robot, such as the arm, joints, and actuators. The main types of bearings used in robots are: Ball bearings: These are the most common type of bearings used in robots. They consist of a series of steel balls housed within a metal cage, which are used to reduce friction and allow for smooth motion. Roller bearings: Roller bearings are similar to ball bearings, but instead of steel balls, they use cylindrical rollers. These bearings are typically used in applications where high loads and heavy impacts are expected. Spherical bearings: Spherical bearings are used in joints and actuators that require more complex motions, such as rotational and radial movements. They consist of a spherical outer surface and an inner surface that allows for movement in multiple directions. Linear bearings: Linear bearings are used to support and guide the movement of parts in a straight line, such as a robot arm. They are commonly used in high-precision applications where smooth, accurate motion is required. Plain bearings: Plain bearings are the simplest type of bearings, consisting of a metal shaft and a metal casing that houses it. They are commonly used in lower-load, lower-speed applications. Robot bearings play a critical role in ensuring the reliability and performance of robots. Proper selection and maintenance of bearings can help to prevent wear and tear, reduce friction and heat, and ensure smooth and accurate motion of the robot.

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-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.

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 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.
