DH 513 FAG

Applications

The DH 513 FAG is a precision-machined distance ring used in bearing and rotary shaft seal assemblies. It ensures correct axial positioning of the bearing and associated shaft sealing components, supporting stable alignment in rotating systems. This element plays a critical role in maintaining proper preload, preventing excessive friction, and ensuring long-term sealing performance.
It is used across a wide range of industrial applications, including gearboxes, electric motors, drive systems, pumps, agricultural machinery, and automotive assemblies where precise shaft alignment and sealing reliability are essential.

Advantages

The DH 513 spacer ring provides consistent positioning of the bearing relative to the rotary shaft seal or oil seal, improving system reliability under variable load and speed conditions. By maintaining correct axial clearance, it helps reduce wear on sealing lips, improves sealing efficiency, and prevents premature component failure.
Manufactured to FAG’s precision tolerances, the ring is resistant to deformation and maintains dimensional stability even in demanding mechanical environments, ensuring durability in continuous industrial operation.

Main Description

The DH 513 FAG distance ring is an integral component in rotary assemblies where bearings and rotary shaft seals must be positioned with high precision. In systems involving shaft rotation, the interaction between the bearing and the oil seal is critical: improper alignment or incorrect axial spacing can result in leakage, heating, vibration, and accelerated wear.
By ensuring the correct axial distance between the bearing and the sealing ring, the DH 513 helps maintain a stable sealing line, improving sealing reliability in both single lip and double lip seal configurations. This is particularly important in environments where shaft seals are exposed to oils, greases, or fluctuating thermal and mechanical loads.
The spacer ring supports machine longevity by preventing misalignment that could otherwise lead to surface damage or seal distortion. It is suitable for OEM production, scheduled maintenance, and industrial repair programs where consistent performance and geometry must be maintained.
Designed to function alongside rotary seals, shaft sealing rings, and radial bearings, the DH 513 contributes to efficient operation in industrial power transmission systems, rotating equipment, and automated machinery.
