Features & Benefits

• Non-contact seals on both sides reduce friction and enhance longevity

• Basic dynamic load rating of 5.4kN ensures reliability under heavy loads

• Static load rating of 4kN supports stability in stationary applications

• Parallel bore design simplifies installation in machinery

• Lightweight at only 0.04kg for easy handling and deployment

• Suitable for high speeds, with a limiting speed of 12000r/min for efficiency

Applications

• Used in various mechanical assemblies for smooth operation

• Integrated into automation systems for consistent performance

• Utilised in electrical devices requiring reliable component support

• Perfect for industrial equipment where high load ratings are crucial

What materials are used in the construction?

The bearing is made of high-quality steel, ensuring strength and resistance to wear under normal operating conditions. The cage is composed of sheet metal, designed to accommodate the bearing's operation effectively.

How does the sealing arrangement benefit usage?

The non-contact seals on both sides effectively prevent contaminants from entering, thereby reducing maintenance needs and extending the lifespan of the bearing. This ensures optimal performance in challenging environments.

What are the implications of its low mass?

A mass of only 0.04kg promotes ease of installation and manipulation, particularly in fields where space and weight constraints are paramount, such as electronics and automated systems.

What performance metrics should be monitored during operation?

Users should pay attention to the load ratings, specifically the dynamic and static ratings, alongside monitoring the operating speed to maximise performance and prevent premature failure.

How does this bearing ensure efficiency in high-speed applications?

With a limiting speed of 12000r/min, the design caters to environments that require fast rotational speeds while maintaining stability and reliability under load, making it ideal for dynamic industries.
