MR364DB Miniature Angular Contact Ball Bearing 3×6×4 mm for Robotic Finger Joints

Compact bearing support for robotic finger joints

Space is a critical constraint in robotic fingers and dexterous hand mechanisms. BEINING MR364DB offers a 3×6×4 mm miniature angular contact bearing format for engineers developing compact joint assemblies.

Use the dimensions and catalog ratings below as a starting point for selection. Final suitability depends on the joint's load direction, duty cycle, mounting arrangement, lubrication and required operating accuracy.

Technical specifications

Specifications are transcribed from the MR364DB row of the supplied BEINING product selection table. Limiting speeds are catalog values, not guaranteed operating speeds for every installation. Basic load ratings are bearing selection values and must not be interpreted as permissible robotic fingertip forces.

Product highlights

• Compact dimensions: 3 mm bore, 6 mm outside diameter and 4 mm width for space-constrained joint layouts.
• Application-focused product family: listed in BEINING's robot-finger joint miniature angular contact ball bearing series.
• Defined selection data: published dimensions, chamfer values, load ratings and lubrication-specific limiting speeds support initial engineering evaluation.

Applications for evaluation

• Robotic finger joint bearing support
• Dexterous robotic hand mechanisms
• Compact precision pivot and rotary assemblies with compatible requirements

Application suitability should be verified against the assembly drawing and actual operating conditions.

Selection and installation considerations

Before ordering, confirm the contact angle, bearing arrangement, precision grade, preload or clearance, materials, cage and sealing configuration against the approved MR364DB drawing. These details are not specified in the supplied model row.

Select lubrication and operating speed for the actual load, temperature and duty cycle. Verify shaft and housing fits, shoulder geometry and assembly procedures using the approved drawing. Avoid transmitting installation force through the rolling elements.

Frequently asked questions

What size is the MR364DB bearing?

The catalog dimensions are 3 mm inner diameter × 6 mm outer diameter × 4 mm width.

What are the basic load ratings?

The supplied table lists a basic dynamic load rating of 310 N and a basic static load rating of 140 N.

What are the limiting speeds?

The table lists 18,000 rpm with grease lubrication and 27,000 rpm with oil lubrication under its non-contact heading. Actual operating speed depends on the complete installation and operating conditions.

Is a contact angle or precision grade specified?

The MR364DB row does not specify either. Request the product drawing and confirm these details with BEINING before purchase.
