German Hepco bearings Hepco models Hepco prices

Hepco bearings are a type of rolling bearing. Spherical alloy steel balls are installed between the inner and outer steel rings to reduce friction during power transmission and improve mechanical power transmission efficiency through rolling motion. Ball bearings cannot withstand heavy loads and are common in light industrial machinery. Ball bearings are also called ball bearings.

Hepco bearing introduction

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 coincides with the bearing center, so it has the same self-aligning function as automatic self-aligning ball bearings. When the shaft or housing deflects, it can automatically adjust without increasing the bearing load. Self-aligning roller bearings can withstand radial loads and axial loads in two directions. They have high radial load capacity and are suitable for heavy load and shock load conditions. Bearings with tapered bore inner rings can be mounted directly or 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 bore and tapered bore structures. Cage materials include steel plates and synthetic resins. Their feature is that the outer ring raceway is spherical, providing automatic self-alignment to compensate for errors caused by misalignment and shaft deflection. However, 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 of this type of bearing is spherical, it has self-aligning performance. The bearing can still operate when the relative inclination between the inner ring center line and the outer ring center line does not exceed 1°～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 performance, annular oil grooves and three oil holes are machined on the outer ring.

Hepco bearing features and structure

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 and allows normal operation under conditions of small relative inclination between the inner and outer rings. It is suitable for components where strict coaxiality of support seat holes 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 ℃ and + 120 ℃. Main applications of self-aligning ball bearings: Suitable for precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. They are the most widely used type of bearing in the mechanical industry.

Hepco bearing sealing

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 and have different structural forms such as gap seals, labyrinth seals, and gasket seals. Contact seals are suitable for medium and low-speed working conditions, with common structural forms including felt seals and leather cup seals. According to the sealing requirements of bearing working conditions and environments, engineering design often comprehensively uses various sealing forms to achieve better sealing effects. The selection of external bearing seals should consider the following main factors: bearing lubricant type (grease and oil); bearing working environment and space occupation; advantages of shaft support structure and allowable angular deviation; circumferential speed of the sealing surface; bearing operating temperature; and manufacturing cost.
