NTN plummer blocks
have almost the same design with Chinese plummer blocks standard,it is made of gray cast iron,cast iron materials boasts the greatest vibration damptening capability among various metal materials. they also perform well in a wider operating temperature range of -20 to 300 degree. for application involving shock load and vibration,spheroidal graphite cast iron or carbon cast steel is used. NTN Plummer blocks can working with NTN spherical roller bearings,we called NTN Plummer blocks units,when the contact surfaces of spherical roller bearing raceway and rolling elements are repeatedly subjected to heavy stress,they still must maintain high precision and running accuracy, to accomplish this, the raceway and rolling elements must be made of a material that has high hardness ,is resistant to rolling fatigue,is wear resistant,and has good dimensional stability, by using pure materials, high quality material can make high quality Plummer blocks and NTN spherical roller bearings,and NTN Plummer blocks and NTN Spherical roller bearing can decide service life of NTN plummer block units.
Structure of NTN Plummer blocks
the bolt protects the plummer block againest loosening due to vibration and impact
Oil fill plug for relubrication
Seal:excellent sealing performance
adapter:Simplifies installation of the spherical roller bearing
Self-aligning ball or roller bearing is built into plummer block
Oil drain plug for draining old lubrication
Mount bolt holes allow easy positioning and installation
Plummer block unit designed for greater machanical strengh ,and manufacturered
under strict quality control program,to suit the intended application,it can be
made of either spheroidal graphite cast iron or cast steel.
Knock ball:the upper and lower housings can be assembled together at higher accuracy
thanks to ball-knock system using steel balls,also the upper cover can be installed or remove
