INA bearings is superior even turn form will be announced low whining sound percussion scars noise can also occur, and noise will be followed by a thin wall bearing speed bump differences.
If intermittent noise, transparent. If announced a sharp hissing sound, creak sound and do not behave the sound often revealed the performance bearing is bad even turn.
To be elected on the heavy-duty work in addition to the small penetration penetration grease under high pressure, but also have a higher film strength and extreme pressure performance. According to the environmental conditions to select the grease, a calcium-based grease is not easy to dissolve in water, suitable for drying and moisture less environment. INA Bearing grease calcium base grease sodium grease calcium sodium base grease lithium base grease aluminum grease and molybdenum disulfide grease, etc.. The number of bearing grease filling to 1/2-1/3 of the overflowing inside the bearing space as appropriate. Speed should be reduced to 1/3 of the excess grease will make the temperature rise higher.
The temperature of the bearing, usually the outside temperature of the bearing housing can be inferred, and if the use of the hole can directly measure the temperature of the thin-walled bearing outer even bit suitable. Typically, INA bearing temperature steady state is reached after 1-2 hours with the bearings running slowly began to rise. The bearing normal temperature varies due to the heat capacity of the machine, the amount of heat, the rotational speed and load. If appropriate lubrication, installation, bearing temperature will rise abrupt, abnormal high temperature must stop running, take the necessary precautions.
Bearing is a precision mechanical support components, the INA bearings users sincerely hope that the bearing can be installed on the host in a predetermined period of use without damage and to maintain its dynamic performance, but the objective fact that sometimes is not satisfactory, unexpected bearing failure The accident could cause significant losses. Through a lot of bearing failure analysis of bearings short-lived or premature loss of accuracy, some due to defects in material or manufacturing improper, but to a large extent on the absence of strict accordance with the requirements of bearings for installation, maintenance, or bearing improper selection or actual load exceeds the rated load of the thin wall bearing bearing non-normal damage.
Bearing cracking peeling INA bearing cycle load, the contact surface is very prone to fatigue failure, so in order to improve the life of the bearing, the bearing steel must have a high contact fatigue strength.
Hardness is one of the important quality of bearing quality has a direct impact on contact fatigue strength, wear resistance, elastic limit. Thin wall bearing the hardness of the steel in the use of state general to reach HRC61 ~ 65, to the bearing high contact fatigue strength and wear resistance.
Nylon 46 manufactured holder reducing the ball and the holding of the sliding friction between the frame. Also, elimination of the concavo-convex shape of the direction of rotation, thereby reducing the agitation loss. In addition, by using the stress when the shape of the can slow the assembly to ensure that the assembly performance. The loss of torque of the single holder reduced by 30 to 40%, the thin wall bearing the overall loss of the torque reduced by 50 to 65%. The company speculated that the Prius fuel efficiency by 10 mode and 15 mode from the previous 35.5km / L to 38.0km / L, to improve fuel efficiency of about 1 to 2% is obtained through the use of such bearings.
INA bearing parts in the production process to go through many cold and thermal processing operations, in order to meet the high-volume, high-efficiency, high-quality requirements, the thin-walled bearing steel should have good processing properties. For example, cold, thermoforming performance, cutting performance, hardenability, etc.
