Precision Bearings

Key Features of Precision Bearings

High Accuracy

These bearings are engineered to very tight tolerances to ensure minimal runout and consistent motion. The precision of the bearing is specified by the progressive number in a bearings tolerance class. For ISO standards, the higher the number the higher the bearing precision. However, with DIN standards the lower the number the higher the bearing precision.

Durability

Precision bearings are made from high-grade materials with advanced heat treatments and coatings for wear resistance. They are designed to withstand harsh environments including high speed, loads, and temperatures.

Low friction and smooth operation

These bearings are optimised to reduce vibrations and noise beyond standard bearings

Types of Precision Bearings:

Ball Bearings:

• Angular Contact Ball Bearings: Designed to handle both radial and axial loads, often used in pairs for high-precision applications.

• Deep Groove Ball Bearings: Commonly used for their versatility and ability to handle moderate radial and axial loads.

Roller Bearings:

• Cylindrical Roller Bearings: Suitable for high radial loads and high-speed applications.

• Tapered Roller Bearings: Designed to handle both radial and axial loads, commonly used in automotive and industrial applications.

• Spherical Roller Bearings: Can accommodate misalignment and are used in heavy-duty applications.

Thrust Bearings:

• Thrust Ball Bearings: Designed to handle axial loads in one direction.

• Thrust Roller Bearings: Suitable for high axial loads and can accommodate some radial loads.

Needle Bearings: These bearings have a high length-to-diameter ratio and are used in applications where space is limited but high load capacity is required.

Hybrid Bearings: These bearings use ceramic balls instead of steel balls, offering advantages such as lower weight, higher speed capabilities, and better performance in high-temperature environments.

Advantages of Precision Bearings:

Reliability - Consistent performance under heavy loads and high speeds

Long service life - Resistant to wear and deformation even in harsh environment applications

Enhanced system performance - Ensures stability and precision in motion-critical applications
