German SYSTEM PLAST bearings, SYSTEM PLAST models, SYSTEM PLAST prices

SYSTEM PLAST bearings are a type of rolling bearing that installs spherical alloy steel balls between the inner and outer steel rings to reduce friction during power transmission and improve mechanical power transmission efficiency. Ball bearings cannot withstand heavy loads and are common in light industrial machinery. Ball bearings are also called ball bearings.

Introduction to SYSTEM PLAST bearings

Self-aligning ball bearings are bearings with spherical balls assembled between an inner ring with two raceways and an outer ring with a spherical raceway. The center of curvature of the outer ring raceway surface aligns with the bearing center, providing the same self-aligning function as automatic self-aligning ball bearings. They can automatically adjust when the shaft or housing deflects, without increasing the bearing load. Spherical roller bearings can withstand radial loads and axial loads in both directions. They have high radial load capacity and are suitable for heavy and shock load conditions. Bearings with tapered bore inner rings can be mounted directly or installed on cylindrical shafts using adapter sleeves or withdrawal sleeves. Cages include stamped steel cages, molded polyamide cages, and machined copper alloy cages. Self-aligning ball bearings come in cylindrical and tapered bore structures, with cage materials such as steel plates and synthetic resins. Their feature is a spherical outer ring raceway, providing automatic self-alignment to compensate for errors caused by misalignment and shaft deflection, but the relative inclination between the inner and outer rings must not exceed 3 degrees. They can withstand large radial loads and certain axial loads. Since the outer ring raceway is spherical, they have self-aligning performance; the bearing can still operate when the relative inclination between the inner and outer ring centerlines does not exceed 1° to 2.5° due to shaft bending or tilting. Self-aligning ball bearings have cylindrical and tapered bores. The taper of the tapered bore is 1:1 2 or 1:30. To enhance lubrication, annular oil grooves and three oil holes are machined into the outer ring.

Features and structure of SYSTEM PLAST bearings

Primarily withstands radial loads and smaller axial loads. Axial displacement of the shaft (housing) is limited within the clearance range. It has automatic self-aligning performance, allowing normal operation under conditions of small relative inclination between the inner and outer rings. It is suitable for components where strict coaxiality of the support housing bore cannot be guaranteed. Structural forms: Self-aligning ball bearings with dust covers and seals are filled with an appropriate amount of grease during assembly. They should not be heated or cleaned before installation and do not require re-lubrication during use. They are suitable for operating temperatures between -30 °C and +120 °C. Main applications of self-aligning ball bearings: Suitable for precision instruments, low-noise motors, automobiles, motorcycles, and general machinery, making them one of the most widely used bearings in the mechanical industry.

SYSTEM PLAST bearing seals

Bearing seals can be divided into integral seals and external seals. Integral bearing seals mean the bearing itself is manufactured with sealing devices, such as dust covers and sealing rings. This type of seal occupies little space, is easy to install and remove, and has a relatively low cost. External bearing sealing devices refer to sealing devices with various performances manufactured inside end caps, etc. External bearing seals are further divided into non-contact seals and contact seals. Non-contact seals are suitable for high-speed and high-temperature applications, with structures such as gap seals, labyrinth seals, and washer seals. Contact seals are suitable for medium and low-speed operating conditions, with common structures such as felt seals and leather cup seals. Depending on the sealing requirements of the bearing's operating conditions and environment, engineering designs often combine various seal types to achieve better sealing effects. The selection of external bearing seals should consider the following main factors: bearing lubricant type (grease and oil); bearing operating environment and space occupancy; advantages of the shaft support structure and allowable angular misalignment; circumferential speed of the sealing surface; bearing operating temperature; and manufacturing cost.
