NSK Industries - Rotary Coal Valve: RHP HLT bearing insert within a Self-Lube cast iron FC housing generate significant cost saving
metal sheet during manufacturing from a cold mill.
60mm shaft and running at approximately 1485 rpm.
high temperature environments with special grease.
NSK Industries - Pilger Mill: NSK proposed a special Spherical Roller Bearing with optimised internal design and Super Tough (STF) steel.
NSK Industries - Cold Form Saw for Steel Tube: No failures after 12 months of operation due to replacement to NSK ball screw support unit
products due to bearing failures within their wire guides
NSK Industries - Air Recirculation Fan: Significant cost saving generated by removing the need for compressed air cooling
a Sealed Double Row CylindricalRoller Bearing Unit
housing together with aspecial heat isolating spacer.
standard bearings provided 1.400 hours of operation.
NSK Industries - Quench Conveyor: NSK stainless steel Molded-Oil bearings last 12 months operation without failure
continuous cast roller was about one to two months.
NSK Industries - Plate Rolling Mill: NSK Sealed Clean 4 row tapered roller bearing assembly reduce grease disposal costs & maintenance time.
sealing arrangement were inadequate for the application
rails, the stiffness of the spindle was critical.
