Longer Life Adopted NACHI original seal design to prevent contamination and grease leakage. Contains special grease for wider temperature ranges and longer life. Smooth and Quiet Operation The precision level of our bearing components has been enhanced to ensure smooth and quiet operation. Low Torque Lower rotating torque by improving seal lips.

Standerd Configuration of Single-row, Deep-groove Ball Bearings

	Configuration	Design	Cross section
Sealed or shielded Bearings	Open (no seals, shields)	Consists of inner and outer rings, balls, and cage.
	Shield	One or two steel shields provide labyrinth clearance
	Non-contact Rubber Seal	One or two non-contact rubber seald provide labyrinth clearance
	Contact Rubber Seal	One or two contact rubber seals in contact with inner ring
Snap-ring Groove in Outer Ring	N: with snap-ring groove in outer ring. NR: with groove and snap ring in outer ring. (Use of snap ring allows easy mounting and simplified housing design.) Bearings may also be sealed or shielded.
Flanged Outer Ring	Wiith flanged outer ring. Applicable to Extra-small and Miniature bearings. Bearings may also be sealed or shielded.

• Electric Motors
  Quiet operation realized by proper clearance, recommend fitting practice. Lower noise lubricants. Suitable for all speed ranges applications requiring low noise.
• Automotive Alternators
  Longer life in vibrations and high temperature environments.
• Automotive Starters
  High reliability in periodic use of vibrations and high temperature environments.
• Compressors
  Long life pump rotors which compress air in low temperature and low viscosity lubrication environments.
• Blowers
  Quiet and stable operation on fan rotors at high speed, in environments with vibration and high temperatures
• Transmissions
  Compact design for light weight to achieve high performance.
