German ROLLIX bearings ROLLIX models ROLLIX prices

ROLLIX bearings are a type of rolling bearing that install spherical alloy steel balls 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.

ROLLIX 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, 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. Self-aligning roller bearings can withstand radial loads and axial loads in both directions. They have high radial load capacity and are suitable for applications with heavy loads and impact loads. 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 bore and tapered bore structures, with cage materials including steel plates and synthetic resins. Their characteristic is the spherical shape of the outer ring raceway, 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 significant radial loads and certain axial loads. Since the outer ring raceway is spherical, these bearings have self-aligning performance. When the shaft bends or tilts due to force, causing the relative inclination between the inner ring centerline and outer ring centerline to remain within 1°～2.5°, the bearing continues to operate. Self-aligning ball bearings have cylindrical and tapered bores. The taper of the conical bore is 1：1 2 or 1：30. To enhance lubrication performance, annular oil grooves and three oil holes are machined into the outer ring.

ROLLIX bearing features and structure

Primarily withstands radial loads while also handling smaller axial loads. Axial displacement of the shaft (housing) is limited within clearance limits, providing automatic self-aligning performance. Allows normal operation under conditions of small relative inclination between inner and outer rings, making it suitable for components where support seat holes cannot strictly ensure coaxiality. Structural forms: Self-aligning ball bearings with dust covers and seals are pre-filled with appropriate amounts of grease during assembly. No heating or cleaning is required before installation, and no further lubrication is needed during use. 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, making them one of the most widely used bearing types in the mechanical industry.

ROLLIX bearing sealing

Bearing seals can be divided into two categories: integral seals and external seals. Integral bearing seals refer to bearings that are manufactured with built-in sealing devices, such as dust covers and sealing rings. This type of seal occupies very little space, is easy to install and remove, and has a relatively low cost. External bearing sealing devices refer to sealing mechanisms with various performance characteristics that are created within components like end caps during installation. External bearing seals are further classified into non-contact seals and contact seals. Non-contact seals are suitable for high-speed and high-temperature applications and come in different structural forms such as clearance-type, labyrinth-type, and gasket-type. Contact seals are suitable for medium and low-speed operating conditions, with common structural forms including felt seals and leather cup seals. Depending on the sealing requirements dictated by the bearing's operating conditions and working environment, engineering designs often combine various sealing methods to achieve better sealing performance. The selection of external bearing seals should consider the following main factors: the type of bearing lubricant (grease and oil); the bearing's working environment and space constraints; advantages of the shaft support structure and allowable angular misalignment; the circumferential speed of the sealing surface; the bearing's operating temperature; and manufacturing costs.
