HERO BEARING CO., LIMITED In bearings of this type, Bearing NNU4988-S-K-M-SP FAG are in linear contact with the raceways. Cylindrical Roller Bearings Distributior have a high radial load capacity and are suitable for high speeds.
Bearing NNU4988-S-K-M-SP FAG There are different types designated as NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings Cylindrical Roller Bearings Distributior depending on the design or absence of side ribs).
The outer and inner rings of all types are separable.
HERO BEARING CO., LIMITED Some cylindrical roller bearings Bearing NNU4988-S-K-M-SP FAG have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings Cylindrical Roller Bearings Distributior have high radial rigidity and are used primarily for precision machine tools.
Cylindrical Roller Bearings Distributior Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.
Depending on the existence of ribs on their rings, Cylindrical Roller Bearings are classified into the following types:
Types NU, N, NNU, and NN are suitable as free-end bearings. Bearing NNU4988-S-K-M-SP FAG Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings Cylindrical Roller Bearings Distributior.
NH-type cylindrical roller bearings Bearing NNU4988-S-K-M-SP FAG consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars.
