Product Description

Bronze Bushing – Spherical Sintered 3×6×7 mm

SINTERED BRONZE SPHERICAL BUSHING 3X6X7 Additional image 1

DALON’s 3×6×7 mm sintered bronze spherical bushing is engineered for micro-scale precision movement in compact mechanical systems. Designed with a spherical outer surface and a sintered bronze body, this bushing offers self-aligning capability, self-lubrication, and excellent vibration damping — even in tight assembly spaces.

The porous bronze matrix is oil-impregnated through powder metallurgy, ensuring long-term operation without external lubrication. This type of bushing is ideal for reducing friction and misalignment in applications where precise shaft guidance is critical.


Key Features

  • Dimensions:
      • Inner Diameter (ID): 3 mm
      • Outer Diameter (OD): 6 mm
      • Length: 7 mm

  • Design: Spherical self-aligning outer surface

  • Material: Sintered bronze (oil-impregnated)

  • Performance:
      • Maintenance-free self-lubrication
      • Low-noise, low-friction operation
      • Compact and lightweight

  • Ideal for high-frequency, low-load applications


Applications

  • Micro motors and sensor assemblies

  • Medical and lab automation devices

  • Optical equipment and instrumentation

  • Drones and precision robotics

  • Gearboxes in compact actuators


Why Choose DALON

DALON is an ISO 9001:2015-certified manufacturer of precision sintered bushings and bearings. Our spherical bronze bushings are trusted by global OEMs for their alignment accuracy, lubrication stability, and manufacturing consistency.

FAQ – Frequently Asked Questions

Q1: What is the purpose of the spherical outer design?
The spherical shape allows the bushing to self-align within a housing, compensating for small misalignments during operation.

Q2: Can this bushing be used without external oil or grease?
Yes. It is fully oil-impregnated and requires no additional lubrication under normal conditions.

Q3: Is this bushing suitable for continuous rotation?
It’s ideal for oscillating or low-speed rotation in compact systems with light to moderate loads.

Q4: What environments is it best suited for?
It performs well in dry or low-moisture environments, especially where space is limited and frequent maintenance is not feasible.

Q5: Can I order this in custom dimensions or tolerances?
Yes. DALON offers OEM customization including dimensional tolerances, special lubricants, and packaging formats.
