Bearing Units
 
Bearing Units
NTN bearings units combine a double-sealed ball bearing with various types of bearing housing. These are optimal units which are self-aligning at the spherical fitting surface of the bearing and housing. In particular, set screw type bearing units use NTN's unique set screw with a ball, and this is extremely effective for stopping loosening of the set screw, even when there is a vibrating or impact load. (Ref. catalog "Bearing units" CAT. No. 2400/E etc.)
   
       
Bearing Units with Ductile Cast Iron Housing
In this series, breaking strength has been improved by about 30% over conventional gray cast iron by using ductile spherical graphite cast iron for the housing material. The outer dimensions have been designed to be as small as possible. (Ref. catalog "Bearing Units with Ductile Cast Iron Housing" CAT. No. 3901/E etc.)
 
   
       
Bearing Units Steel Series
The steel housings provide rigidity, high load capacity and impact resistance. Excellent impact resistance. Greater rigidity than with previous cast steel products. (Ref. catalog "Bearing Units Steel Series" CAT. No. 3902/E etc.)
   
       
Bearing Units Stainless Steel Series
The units combine a stainless steel housing and a stainless steel bearing with solid grease. Excellent corrosion resistance. Small lubricant leakage. Low rotation torque. (Ref. catalog "Bearing Units Stainless Series" CAT. No. 3903/E etc.)
   
       
Bearing Units Plastic Series
The units combine a plastic housing and a stainless steel bearing with solid grease. Excellent water and corrosion resistance. Small lubricant leakage. Low rotation torque. (Ref. catalog "Bearing Units Plastic Series" CAT. No. 3904/E etc.)
