MR364DB Miniature Bearings for Robotic Dexterous Hands

A small bearing can be easy to overlook in a robotic hand. Yet choosing one starts with a very practical question: how will it fit into the mechanism?

BEINING's MR364DB is a miniature bearing used in robotic dexterous hand applications, with a specified size of 3 × 6 × 4 mm. The accompanying photograph shows the actual product on a fingertip, giving an immediate sense of its scale.

Product overview

For ordering and integration, please confirm the dimension definitions and assembly arrangement against the approved drawing.

Start with the installation position

When reviewing MR364DB for a dexterous hand project, tell us where the bearing will be installed. A sketch of the shaft, housing and surrounding components is a useful starting point.

Please also indicate whether the bearing supports a finger joint, a transmission component or another part of the mechanism. The application name alone does not define the loads or mounting conditions.

Describe the actual operating conditions

To help us review your requirements, please provide:

• Available installation space and mating shaft and housing dimensions.
• Radial and axial loads, including short-duration peaks.
• Any overturning moment and the distance from the applied force to the bearing.
• Motion type, rotation angle, speed and operating cycle.
• Required clearance or preload, friction torque and positioning requirements.
• Lubrication, temperature and environmental conditions.

If you have a force value measured at the fingertip, include the mechanism layout as well. Please identify where the force acts so that your engineering team and BEINING can review the bearing loading for the actual arrangement.

Confirm the specification before sampling

The MR364DB model and size identify the product discussed here. Load ratings, contact angle, accuracy class, preload, friction torque and expected service life need to be confirmed separately for the agreed specification.

We recommend starting with the drawing and intended operating conditions, then agreeing the sample specification and your evaluation requirements. This gives both teams a clear basis for discussing the results.

Discuss your dexterous hand bearing project

Looking for a miniature bearing for a robotic hand? Send BEINING your model, drawing or installation dimensions, together with the expected loads and motion conditions.

We can discuss MR364DB and review your requirements for other miniature or custom bearing projects.
