The main influence of the correct use of grease on the speed of INA forklift bearings

Proper use of grease must be aware of the movement of the grease in the forklift bearings. Guarantee the stability of the grease. The movement of the grease filled in the INA bearing can be roughly divided into two stages as the bearing rotates.

In general, the amount of grease filled in the bearing always exceeds the actual amount of lubrication directly involved in the lubrication, on the frame and in the cavity of the bearing cover, and forms a contour on the periphery of the rolling element. During this process, the bearing temperature rises rapidly due to the resistance of the excess grease. Although most of the excess grease is squeezed out at the beginning of the run, the grease that is squeezed into the raceway attachment may still be carried by the rolling element into the raceway. In the initial stage of bearing operation, most of the grease is squeezed out of the raceway very quickly (less than one minute), and the accumulated grease is discharged a small amount while circulating with the forklift bearing. At this time, the INA bearing temperature continues to rise until the excess grease is completely discharged, which can be called the grease's walking phase. According to the grease quality and filling amount in the bearing structure, this time may last for more than ten. Minutes, even hours.

The achievable speed of a precision bearing depends mainly on the bearing type, structure, material, type and size of the load, lubricant and lubrication. Operating temperature is an additional limitation in terms of allowable speed.

INA bearing configurations operating at high speeds require lower friction and heat for forklift bearings, and precision bearings and bearings are best suited for these applications.

Compared to other high-precision bearing types, INA bearings are able to achieve the highest speeds. The relative speed performance of bearings in different series of bearings is compared.

Precision bearings can achieve the same speed as the 70CD series bearings. Forklift bearings cannot reach the same high speed as radial bearings.

NSK bearing vibration and temperature inspection

The result of frequent use of IKO bearings is an increase in oil stains, which in turn directly reduces the service life of the bearings. How to completely remove the oil on the IKO bearings? The following teaches you a way to easily remove the oil on the IKO bearings.

Bearings hardened by soft dry oil or rust-proof paste should be immersed in hot oil of 100 ° C ~ 200 ° C, clamp the bearing with pliers, and brush the oil on the bearing with a brush. The soft dry oil or anti-rust paste is melted when heated to 100 ° C ~ 200 ° C, and is easily washed out from the gap of the bearing. Sometimes the bearing is shaken several times in the oil. Oil will also flow away from the gap.

When cleaning the centripetal spherical bearing of IKO bearing, the ball, bead frame and inner ring should be laterally transferred out from the outer ring and then immersed in hot oil. When cleaning the short cylindrical roller bearing, the roller and bead frame should also be used. The inner ring and the outer ring are disengaged.

When hot oil is cleaned, the temperature of the oil should not exceed 20 °C.
