INA Bearing Company, a division of The Schaeffler Group, is focused on the production of high quality roller bearings, plain bearings and linear components.  INA Bearings Company also caters to the automotive industry with their extensive line of precision parts designated for the various inner workings of car engines, transmission and power trains.

 

INA Bearing Company was first created by Dr. Georg Schaeffler when he invented the needle roller bearing with cage assembly.  This was a pioneering feat in the bearing industry and INA continues to be on the cutting edge of the latest technologies.  INA uses this knowledge to produce a well-designed, high quality product that is still extremely cost-effective for the average consumer.

 

INA currently has sixty three different manufacturing facilities around the world and this helps keep them competitive in the ever-changing global marketplace.  if a customer is looking for bearings ranging from angular contact and radial ball bearings to drawn cup and needle roller bearings, INA Bearing Company has a product to meet the discerning customers needs.  Dalton Bearing Service, Inc. is proud to be an INA distributor and would be happy to answer any questions you might have regarding their extensive product line.

 

Radial insert ball bearings are single row, rady-to-fit units comprising a solid outer ring, an inner ring extended on one or both sides, cages made from plastic or sheet steel and P, R, L or T seals. Bearings with an inner ring extended on both sides undergo less tilting of the inner ring and therefore run more smoothly.

 

The outer ring has a crowned or cylindrical outside surface. In conjunction with an INA housing matched to the bearing type, bearings with a crowned outside surface compensate for shaft misalignments; see Compensation of misalignments.

 

They are located on the shaft by means of an eccentric locking collar, grub screws in the inner ring, an adapter sleeve, drive slot or fit. Radial insert ball bearings are particularly easy to fit, suitable for drawn shafts of grade h6 to h9 and, with a few exceptions, can be relubricated.

Some series with an eccentric locking collar and with grub screws in the inner ring are also available with an inch size bore.

 

Crossed roller bearings are bearings for precision applications that correspond in their dimensions to ISO dimension series 18 in accordance with DIN 616. They comprise outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and is held together by three retaining rings.

 

Due to the X arrangement of the rolling elements, these bearings can support axial forces from both directions as well as radial forces, tilting moment loads and any combination of loads with a single bearing position. This allows designs with two bearing positions to be reduced to a single bearing position. Crossed roller bearings are very rigid, have high running accuracy and are supplied with normal clearance, little clearance or preload. The bearing outer rings can be easily located in the adjacent construction by means of clamping rings.
