Detailed Product Description


ZINA  produces cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete the ZINA standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds.

The rollers of ZINA cylindrical roller bearings are a key component. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and optimizes rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability and a greater insensitivity to misalignment.

The ZINA range of cylindrical roller bearings comprises the basic types

single row cylindrical roller bearings, caged, mainly of the NU, NJ, NUP and N designs
double row cylindrical roller bearings, caged, mainly of the NNU and NN designs
multi-row cylindrical roller bearings, caged
single row full complement cylindrical roller bearings, mainly of the NCF and NJG designs
double row full complement cylindrical roller bearings, mainly of the NNF design
multi-row full complement cylindrical roller bearings, with four or eight rows of rollers .

In addition to the standard assortment the comprehensive SKF range of cylindrical roller bearings consists of

single row high-precision all-steel or hybrid cylindrical roller bearings
double row high-precision all-steel or hybrid cylindrical roller bearings
cylindrical roller bearings and bearing units for railway axleboxes
single row cylindrical roller bearings for traction motors for railway applications
backing bearings for cold rolling mills of the cluster type
indexing roller units for continuous furnaces .

Other cylindrical roller bearings for special applications include a special electrical insulated coating, called INSOCOAT®. Details of these bearings can be found in this catalogue in the section "".
