Thrust cylindrical roller bearings FAQS

QWhat's the design differences of the cylindrical roller bearings ?

ACylindrical roller bearings are available in many designs, series and sizes. The major design differences between the bearings presented in this section are in: the number of roller rows (one, two or four) the type of cage (with, without or special designs) Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings (without a cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. SKF high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with cage. the configuration of the inner and outer ring flanges (position and number of guide flanges)

QWhat's the different types of cylindrical roller bearings ?

ABearings of this type, the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds. There are different types designated as NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).

QHow to choose proper cylindrical roller bearings ?

ASome cylindrical roller bearings 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 have high radial rigidity and are used primarily for precision machine tools. Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.

QWhat's the bearing feature of Cylindrical roller bearings

AHigh load carrying capacity High stiffness Accommodate axial displacement Except for bearings with flanges on both the inner and outer rings. Low friction The open flange design together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity. Long service life The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection. Enhanced operational reliability The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film. Separable and interchangeable The separable components of SKF cylindrical roller bearings are interchangeable . This facilitates mounting and dismounting, as well as maintenance inspections.
