Super-Precision Angular Contact Ball Bearing

Super-precision angular contact ball bearings can bear composite loads consisting of both radial and axial components. They can also be used to take up high axial loads in one direction.

Engineers use sealed type with ceramic balls to meet the client's demand for low bearing vibration. The seals reduce heat generation and extend grease life by 1.5x compared to open types.

High Load Capacity

Angular contact ball bearings are designed to withstand heavy loads and operate at higher speeds than other types of bearings. They are usually made of 52100 chrome steel, which improves the material’s fatigue life and load ratings. This also allows the bearing to withstand high temperatures, which reduces friction and noise.

This type of bearing can withstand both radial and axial load in opposite directions. However, it is important to note that the axial load capacity of this type of bearing is greater in pairs than in single-row arrangements.

The axial load-carrying capacities of these bearings can be improved by using back to back or face to face bearing arrangements, which increases the shaft or shell two-way axial displacement rigidity. This arrangement can also accommodate moment loading caused by misalignment. This is especially useful in machine tools where high running accuracy is crucial.

High Stiffness

As its name implies, angular contact ball bearings have inner and outer raceways that are displaced relative to each other. This makes them suitable for supporting composite loads that combine radial and axial forces. They are usually mounted in sets and pre-loaded against each other during manufacture. This guarantees constant rolling contact between the balls and the rings, minimizing vibration, increasing accuracy and reducing noise levels.

The terms strength and stiffness are often used interchangeably in common language, but engineers know that they are distinct. Strength is the maximum stress a material can withstand before it breaks or permanently deforms (yield strength). Stiffness, on the other hand, refers to the ability of a material to resist changes in shape when a load is applied.

Specific stiffness (also known as Young's modulus or density) is an important parameter for designing products that require a high degree of rigidity at minimum weight. It is determined by performing a tensile test on a sample of the material.

Low Friction

NSKHPS Precision Angular Contact Ball Bearings are engineered with superior materials and a unique cage design to deliver low friction for maximum machine performance. They are designed to meet the stringent requirements of industry applications such as machine tool main spindles.

The inner and outer ring raceways are offset from each other in the direction of the bearing axis. This allows combined radial and axial loads to be accommodated. Angular contact ball bearings can be used in a variety of applications, including those where high load capacity and stiffness are needed.

These highly durable bearings are manufactured to tight ABEC-7 dimensional tolerance standards and can handle extremely high speeds. They have a Phenolic ball cage which is ideal for high-speeds and helps to keep the bearings lubricated. They are available with a wide range of standard sizes to suit your application. These bearings are also available with sub-ranges dedicated to particular speed, temperature, sealing and specific lubrication requirements.

Low Temperature

Super-precision angular contact ball bearings are often used in tandem arrangements to support axial loads. They feature a 15deg contact angle, tight ABEC-7 manufacturing tolerances, and can handle high speeds. The bearings are usually filled with roller bearing grease for optimal performance. This prevents heat generation and reduces friction and maintenance costs.

These bearings are also used as machine tool spindle bearings due to their exceptional load handling capabilities and ABEC-7 dimensional accuracy standards. They are available in single-row and multi-row variants. They can handle combined radial and axial loads, as well as pure axial load acting in one direction.

Engineers help clients customize proper super-precision angular contact ball bearings according to the actual working conditions and requirements. For example, they helped a client improve the grade mirror of an optical device that analyzes food and agricultural resources by smart analytics. This new technology is expected to optimize the use of food and agricultural products worldwide.
