- Dynamic and static pressure NSK bearings with deep and shallow cavity structures: suitable for high-speed and light-load machine tool spindles, such as M1432 cylindrical grinding, MGA6025 tool grinding, etc.
- Hole type toroidal throttling deep and shallow cavity dynamic and static pressure NSK bearings: suitable for medium speed and medium load machine tool spindles, such as MG1432 cylindrical grinding, MM7150 flat grinding, M1080 centerless grinding, roller grinding, etc.
- Pin type internal reaction dynamic and static pressure NSK bearings: suitable for machine tool spindles with a wide range of load and speed changes.
- Tapered static pressure NSK bearings: suitable for high-speed internal grinding head spindle systems (such as 2110 internal grinding head), electric spindles, and internal channel grinders.
Precautions for use
- The 2# spindle oil and coarse and fine filter elements should be replaced after one year of normal use.
- When the pump station is used normally and needs to be replenished with oil, three layers of silk cloth must be filtered.
- When loading and unloading the spindle pulley and grinding wheel, the pump station must be stopped while the pump station is working. That is, the spindle stops with the hydrostatic oil floating. This will not damage the spindle and dynamic and static pressure NSK bearings.
- Before working on the grinding wheel spindle, check whether the pressure of the pump station and the static pressure of the grinding head are within the standard range.
- When the equipment is shut down, be sure to stop the grinding head motor first, and then turn off the pump station after the grinding wheel has stopped, otherwise the grinding head may be easily damaged.
- When replacing any parts on the pump station, be sure to remove the high-pressure oil inlet hose connector first. After replacing the parts, the oil line can circulate on its own for 15-20 minutes before connecting the oil inlet pipe to the grinding head. This ensures The spindle oil entering the grinding head is ultra-clean spindle oil that has been finely filtered. Doing so can extend the service life of the dynamic and static pressure spindle.
