Can a Thin Walled Brass Bushing Handle High Shock Loads at Low Angular Velocity?

In summary, for your specific requirements of withstanding shock loads up to 2.5e5 N at low angular velocity with an outer diameter limit of 30mm, a thin walled solid brass bushing with a steel shaft would be a suitable option. However, factors such as the direction of the shock loads, maximum RPM under load, available lubrication, and frequency of shocks should also be taken into consideration for optimal performance.

I'm looking for a (needle?) bearing that can sustain shock loads of up to 2.5e5 N, at low angular velocity, but its outer diameter can't be greater than 30mm.

as ridiculous as it sounds, any suggestions?

I would suggest something like a thin walled solid brass bushing with a steel shaft.

I assume your predicted shock loads are perpendicular to the axis of rotation.
A needle bearing might work OK at higher speeds but without many such big shocks.
The size of the shaft will be critical as it determines the contact area, shaft bending and strength. Use the biggest shaft OD possible.

“Low angular velocity” is a bit vague. What is the maximum RPM under load?
What lubrication is available?
How often does it receive a shock of that magnitude?
 

1. What is a high load low-speed bearing?

A high load low-speed bearing is a type of bearing designed to support heavy loads at low rotational speeds. These bearings typically have a large contact area and are able to distribute the load evenly, making them suitable for applications such as heavy machinery, construction equipment, and wind turbines.

2. How does a high load low-speed bearing differ from other bearings?

A high load low-speed bearing differs from other bearings in its design and materials. These bearings are specifically designed to withstand high loads and low speeds, and are often made with materials such as steel or bronze to increase their strength and durability.

3. What factors should be considered when choosing a high load low-speed bearing?

When choosing a high load low-speed bearing, it is important to consider the load capacity, speed capability, and operating conditions of the application. The type of load (radial or axial), the direction of the load, and the level of shock and vibration should also be taken into account.

4. How can the lifespan of a high load low-speed bearing be extended?

The lifespan of a high load low-speed bearing can be extended by properly lubricating it, avoiding overloading, and regularly inspecting and maintaining the bearing. Using a bearing with a higher load capacity than needed can also help prolong its lifespan.

5. Are there any limitations to using high load low-speed bearings?

While high load low-speed bearings are designed to handle heavy loads and low speeds, they may not be suitable for high-speed or high-precision applications. It is important to consider the specific requirements of the application and consult with a bearing expert to determine if a high load low-speed bearing is the best choice.
