Pillow block & Plummer block：SN505

Basic Parameters

The SN505 bearing belongs to the series of spherical outside surface bearings with a housing. Its inner diameter size is 20 millimeters. This size determines that it can fit shafts of specific diameters and plays a crucial supporting and rotating role in numerous mechanical equipment.

Structural Features

• The outer ring of the SN505 bearing has an outer spherical structure. This design enables it to perfectly match with the bearing housing with an inner spherical surface. During actual installation and use, this spherical fit endows the bearing with the function of automatic alignment. This means that when the shaft of the equipment undergoes a certain degree of deflection deformation during operation or there is a slight deviation in installation, the SN505 bearing can automatically adjust its own position to ensure good contact and rotational state between the shaft and the bearing, greatly reducing the additional stress and wear caused by misalignment of the shaft.

• The bearing is composed of an inner ring, an outer ring, rolling elements and a cage. The rolling elements are evenly distributed on the raceway between the inner and outer rings. The rolling elements are usually spherical. The cage plays the role of separating the rolling elements and guiding the rolling elements to roll orderly on the raceway, reducing the mutual friction and collision between the rolling elements, thereby improving the operating efficiency and service life of the bearing.

Performance Advantages

• The SN505 bearing can withstand a certain radial load. In small to medium-sized mechanical equipment, for those radial forces on the rotating shaft, it can provide stable and reliable support. For example, in the drum support of small conveyor equipment and the transmission shaft part of light machinery, it can effectively bear the radial force generated during the operation of the equipment and ensure the normal operation of the equipment.

• Due to the reasonable fit accuracy between the internal rolling elements and the raceway, the SN505 bearing performs well in terms of speed. Within its designed speed range, it can maintain a low level of friction and heat generation. This makes it suitable for some equipment with certain speed requirements, such as small fans and light motors, and can operate stably for a long time in these equipment.

• The SN505 bearing uses high-quality bearing steel material in the manufacturing process. Through precise processing techniques such as high-precision grinding and lapping processes, the dimensional accuracy and surface quality of each part of the bearing are ensured. This high-quality manufacturing process ensures the durability and stability of the bearing during use. Under normal usage conditions, it can maintain good performance for a long time and reduce the number of equipment shutdowns for bearing failures, thereby improving the overall operating efficiency and reliability of the equipment.

Product Application

• Small electric motors: Such as small industrial motors and household motors with power within a certain range. The SN505 bearing can be used to support the rotating shaft of the motor, ensuring stable rotation of the shaft during motor operation, reducing vibration and noise, and ensuring efficient operation of the motor.
• Small pumps: Like small clean water pumps, sewage pumps, metering pumps, etc. The SN505 bearing can withstand the radial force and a certain axial force generated by the pump shaft during operation, keeping the impeller of the pump in the correct position and ensuring the normal suction and discharge functions of the pump.
• Conveying equipment: Such as small belt conveyors, screw conveyors, etc. In these devices, the SN505 bearing is used to support the conveying roller shaft or drive shaft, bear the weight and friction generated when conveying materials, ensure the smooth operation of the conveying equipment, and realize efficient material conveyance.
• Food processing machinery: For example, in small food mixers, dough mixers, food conveyor belts, etc. The SN505 bearing can meet the requirements of food processing equipment for hygiene, corrosion resistance, and stable operation, ensuring the safety and efficiency of the food processing process.
• Textile machinery: In some transmission shaft parts of equipment such as small spinning machines and weaving machines, the SN505 bearing can maintain good performance at high speeds, bear various loads during the textile process, ensure the normal operation of textile machinery, and improve the quality and production efficiency of textiles.
• Woodworking machinery: For example, in small woodworking lathes, electric saws, sanding machines, etc. The SN505 bearing can be used to support the rotating parts of these devices. During woodworking processing, it can bear cutting forces and vibration loads, ensuring the accuracy and stability of woodworking machinery and improving processing quality and efficiency.
