18. Lubricants. Grease or oil is usually used to lubrie the bearing. In the case of miniature and small-diameter bearings, most are used for the life of the equipment without replacing the initially filled lubricant. Therefore, when selecting a lubricant, it is necessary to carefully consider the life, torque, rotating performance, noise

Cooling Fan Noise - Sleeve Bearing vs Ball Bearing | Comair Rotron

Introduction Quite often in low-flow electronic cooling fans for computers, where the aerodynamic noise is low, the predominant noise emitted by the fan is generated in the bearing system. This type of fan usually has either an oil-impregnated sleeve bearing or ball bearings. Both bearing systems create noise that can be very different in both frequency content and amplitude. It is …

If the viscosity of the grease base oil is higher than 1000mm2/s at 40 C, its oiling rate will be very low and the bearing cannot be sufficiently lubried. If the calculated viscosity at 40°C is much higher than 1000mm2/s because of the low speed, it is best to use a grease with a viscosity of 1000mm2/s or less and good oiling characteristics, or use oil lubriion.

Low viscosity oils (or greases with low viscosity base oils) are preferred for high speed appliions as they generate less heat. Although greases often provide much greater resistance than oils, many modern low torque greases can produce torque figures that are similar to some oils, particularly where a low grease fill is used.

Ball Bearing Lubriion | Lily Bearing

When ball bearings are ordered without a specified lubricant, it is the policy of LILY Bearing to lubrie with MIL-L-6085 oil. Standard bearing lubricants are Windsor L-245X oil and Royco 27 grease. The standard quantity of oil varies with bearing size, but is approximately one drop (3 - 6mg) per bearing up to R-2 size and two drops (6 - 12mg
