About this item
  • Size: SMR74-2RS hybrid ceramic ball bearing (Inner Dia.=4mm, Outer Dia.=7mm, Thickness=2.5mm).
  • Enhanced Performance: Hybrid ceramic ball bearings combine the durability of steel bearings with the lightweight and corrosion-resistant properties of ceramic materials
  • High-Speed Capability: Ceramic Si3N4 balls and AISI440C stainless steel offer superior performance compared to traditional steel bearings, providing smoother rotation, reduced friction, making them great for high-speed and high-precision applications
  • Double Sealed: Sealed on both sides with rubber to protect against dust, dirt, and moisture, ensuring smooth operation and extending its lifespan.
  • ABEC 3 Precision Bearing: Lower manufacturing tolerances compared to lower-rated bearings, resulting in smoother rotation and less friction.
  • In stock, ready to ship

Description
  1. Enhanced Performance: Hybrid ceramic ball bearings combine the durability of steel bearings with the lightweight and corrosion-resistant properties of ceramic materials
  2. High-Speed Capability: Ceramic Si3N4 balls and AISI440C stainless steel offer superior performance compared to traditional steel bearings, providing smoother rotation, reduced friction, making them great for high-speed and high-precision applications
  3. Double Sealed: Sealed on both sides with rubber to protect against dust, dirt, and moisture, ensuring smooth operation and extending its lifespan.
  4. ABEC 3 Precision Bearing: Lower manufacturing tolerances compared to lower-rated bearings, resulting in smoother rotation and less friction.
Material
  • Shield Type: Double Rubber Sealed
  • Race Material: 440 Stainless steel
  • Ball Material: Ceramic and Si3N4
Selecting Guide
  • Open Type (No Designation Suffix) - Suitable for high-speed and even very high-speed operation.
  • Shielded (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris.
  • Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than metal-shielded bearings.
