Many people have electric motors in their homes; there are NTN bearings in the motor; some are equipped with domestic bearings; and some are equipped with imported NTN bearings; these motor bearings are the best NTN bearings with good quality; but the length of NTN bearings We still need to use it well; if we don't use NTN bearings; no matter how good NTN bearings are, there is no use; let's analyze how to remove the motor NTN bearings.
The hot oil removal method is used for long-term; soft dry oil or rust-proof paste hardened NTN bearings; should be immersed in 100 200 Â° C hot oil; clamp NTN bearings with pliers; use brush to clean the oil on NTN bearings. The soft dry oil or anti-rust paste is melted when heated to 100 200 Â° C; it is simply washed out from the gap of the NTN bearing. Sometimes the NTN bearing is shaken repeatedly in the oil. The oil will also flow away from the gap.
When removing the centripetal spherical NTN bearing of the old motor or the imported motor; the ball, the bead frame and the inner ring should be laterally turned out from the outer ring and then immersed in the hot oil; the short cylindrical roller NTN bearing should also be removed. The roller, the bead frame, the inner ring and the outer ring are disengaged. When the hot oil is removed; the temperature of the oil should not exceed 20 Â° C. If it is heated directly with an open flame; care should be taken to avoid burning the oil; the NTN bearing should be hung in the In the oil pan, sinking the bottom will lead to overheating and lowering the hardness. NTN bearing common classification: NTN miniature ball imported bearing; NTN deep groove ball imported bearing; NTN radial thrust ball bearing; NTN active self-aligning ball bearing; NTN cylinder Roller bearings; NTN tapered roller bearings; NTN thrust ball bearings; NTN active spherical roller bearings.

Monel alloy 400 has a specific gravity of 8.80,[5] a melting range of 1300-1350 Â°C, an electrical conductivity of approximately 34% IACS, and (in the annealed state) a hardness of 65 Rockwell B. Monel alloy 400 is notable for its toughness, which is maintained over a considerable range of temperatures.
