NMT Needle Roller Bearings High Load Wear Resistant Bearings For Compact Mechanical Equipment In Limited Space
Lots of automatic equipment, hydraulic devices and light machinery are designed to be miniaturized and integrated. The radial space for bearing installation inside equipment is very limited. Conventional bearings have large radial thickness and cannot fit structural layout, while enduring continuous radial loads. Heat dissipation is poor in narrow space, and excessive friction will cause temperature rise and accelerate bearing aging. Some mechanisms carry out composite motion of reciprocating swing and intermittent rotation, putting forward high requirements on wear resistance. Designers need to control overall machine size without reducing load capacity. Needle roller bearings with compact radial size and high load capacity are strongly demanded.
NMT Needle Roller Bearings optimize roller arrangement and make full use of limited radial space to arrange needle rollers, achieving excellent radial load capacity with compact outline. Needle surfaces are precisely ground to guarantee even friction and reduce heat generation during operation. Various structures including inner ring and inner-ring-free types are available to match customized shafts. Surface strengthening treatment improves roller wear resistance for frequent start-stop and reciprocating swing. Seals can be equipped to prevent dust from entering contact surfaces. Standard dimensions support standardized assembly and replacement for compact equipment. Grease lubrication is suitable for continuous operation at medium and low rotating speed.
Types with inner ring, without inner ring and sealed types are available. Selection can be made according to installation space, motion mode and load for rotating and reciprocating mechanisms.
