SMR84 4*8*2 Dental Handpiece Bearing 

 

Product Description:

The SMR84 bearing, a miniature bearing commonly used in dental low-speed equipment, is described as follows:

Dimensions

  • Inner diameter: 4 mm
  • Outer diameter: 8 mm
  • Thickness: Typically 3 mm

Bearing Type

  • Deep groove ball bearing, a type of ball bearing that can withstand radial loads and moderate axial loads, suitable for the operational requirements of dental devices.

Material Properties

  • Ring material: Generally 1440C stainless steel, featuring high corrosion resistance and hardness to resist chemical agents (e.g., disinfectants) used in dental procedures.
  • Cage material: 4300 Series stainless steel, ensuring durability and structural stability during long-term use.

Precision Grade

  • Achieves P5 precision grade, a high-level standard that ensures operational stability and accuracy, meeting the requirements for precise dental procedures.

Radial Clearance

  • Typically ranges from 0.002 mm to 0.013 mm. The small radial clearance minimizes vibration and noise, enabling smooth rotation.

Performance Characteristics

  • Low friction design allows dental low-speed equipment to operate smoothly, reducing energy consumption and heat generation.
  • Exhibits resistance to moderate high and low temperatures, ensuring stable performance in typical dental clinic environments.

Application Scenarios

  • Mainly used in dental low-speed handpieces.
  • Also applicable to precision-demanding fields such as model aircraft toys, printers, copiers, servos, instruments, and micro-motors where space is limited.

 

 

 

Product Features:

1) Regular rotating speed 20000-50000 rpm

2) Tolerance of precision grade P5 (ABEC 5)

3) Maximum rotating speed up 50000 rpm

4) Less vibration, Less noise, Antirust, Corrosion resistant

5) Special design of sealed structure, superiorly dust-proof
