In this type of bearing, cylindrical roller linear is in contact with the race. They have a high radial load capacity and are suitable for high speeds.
There are various types of designated as the NU, NJ, NUP, N, NF (for single row bearings), NNU, and NN (for double row bearing depends on the design or absence of rib side).
Outer and inner rings of all types are separated.
Cylindrical roller bearings a few don't have bones ruSuk ring in good part in or out so that the ring can move axially relative to each other. This can be used as free-end bearing. cylindrical roller bearings, in which either inside or outside the ring has two ribs and the other ring has one, capable of taking some of the load of axial in one direction the cylinder roller bearing two rows have a high radial rigidity and is used mainly for precision machine tools.
Press steel or brass machine kandAng is generally used, but sometimes polyamide cages formed are also used.
Depending on the presence of ribs on their rings, cylindrical Roller Bearings are classified into the following types:
Types of NU, N, NNU, NN and suitable as non-bearing end. Types of NJ and NF can maintain the load actionAl is limited in one direction. Types of NH and the NUP could be used as the fixed-bearing end.
NH-type cylindrical roller bearings consist of NJ-type bearings cylindrical roller and HJ-type L-shaped thrust collar.
The ring loose ribs part of the NUP-type cylindrical roller bearing must be mounted so that the marked side is on the outside.
Cylindrical Roller Bearings (Pressed Steel Cages)
NSK has high load rating" EW Series "
Cylindrical Roller Bearings (Molded Polyamide Cages)
Bearings with polyamide cages formed (type ET) can be used continuously at temperatures between-40 and 120 ℃. If the bearings are used in hydraulic oil, gear oil does not readily ignite or ester oils at high temperatures of more than 100 ℃, please contact NSK in advance.
Cylindrical Roller Bearings > Rong for Sheaves
features 1. Improvement of the seal: contact seal increases resistance to foreign substances or water ingress. 2. high weight capacity: when used as a power support radial and axial loads, the pulley on the rise 3. corrosion resistance: surface treatment of Phosphate increasedright resistance to rust. 4. easy to apply grease: Holes are available on the ring part in facilitating the grease replenishment, even when pads are installed. 5. A little surrounding part: with ring snap ring to the outside, fewer part required about bearings for more cost-effective sheave.
