Product Introduction
Motor bearings, also known as electric motor bearings or motor bearings, are a type of specialized bearing specifically applied to electric motors or motors. The bearing used in a motor is a component that supports the shaft; it can guide the rotation of the shaft and also bear the idle components on the shaft.
Motor bearings reduce friction by using smooth metal balls or rollers and lubricated inner and outer ring metal surfaces. These balls or rollers "carry" the load, support the motor's main shaft, and allow the motor (rotor) to rotate smoothly.
Most small and medium-sized motors use rolling bearings. Large and medium-sized motors also use rolling bearings. Small motors use ball bearings (deep groove ball bearings). Medium-sized motors use roller bearings at the load end (generally for high-load working conditions) and ball bearings at the non-load end (but there are also opposite cases, such as 1050kW motors). Rolling bearings are lubricated with grease, but some are also lubricated with lubricating oil.
Introduction to the classification of motor shaft types
- Linear shaft
A linear shaft refers to a long strip-shaped shaft with a circular cross-section, mainly suitable for machinery and tools that need to achieve linear motion. Common materials for linear shafts include steel, stainless steel, aluminum alloy, etc. Linear shafts are widely used in equipment such as CNC machine tools, printing machines, packaging machines, and elevators. - Circular shaft
A circular shaft is a shaft with a circular cross-section, commonly used in some rotating machinery and tools. The materials of circular shafts can be steel, stainless steel, brass, etc. Circular shafts are widely used in fields such as fans, electric motors, automobile engines, and ships. - Square shaft
A square shaft is a shaft with a square or rectangular cross-section, suitable for machinery and tools that need to twist or rotate. Compared with circular shafts, square shafts have higher torque and torsional hardness. Square shafts are widely used in components such as hydraulic presses, punch presses, wire winches, and transmission boxes. - Hexagonal shaft
A hexagonal shaft is a shaft with a hexagonal cross-section. It has many advantages, such as good torsion resistance and large torque transmission. It is often used in hand tools such as drills, wrenches, screwdrivers, as well as automobile parts and other fields. - Special-shaped shaft
A special-shaped shaft refers to a shaft with an irregular shape, mainly used in some special occasions, such as conical shafts, corrugated shafts, etc. Special-shaped shafts can be designed and processed according to work needs, and are suitable for special machinery and tools.
