How toinstall bearinginto housing

Solution:Check that the housing has the recommended chamfer of 25-30 degrees. If using a sleeve bearing (which typically has only one end with an outside chamfer), match up the bearing’s outside chamfer with the housing-bore chamfer. If using a flange bearing, the sleeve portion (installed) has the outside chamfer already. In both instances, also check the housing bore to ensure it is not undersized.

Problem:Once press-fit into the housing bore, the ID after-press-fit is smaller or larger than the recommended tolerances.

Once the bearings have been installed, they should be ready for operation. However, not every installation goes exactly according to plan. Below are two common post-installation problems with the corresponding solutions recommended by igus®.

Now that the bearing has been installed, you want to perform a quality check. igus® conducts a pin-gauge (go / no-go) test after press-fitting the bearing into the smallest specified housing-bore dimension. Specifically, a "go" signifies the pin falling through the bearing under its own weight, while a "no-go" occurs when the pin does not fall through the bearing, or "sticks".

Conducting quality checks on the bearings after installation is extremely important and can be done in a number of ways. igus® uses a pin-gauge test, also called a “go / no-go” test, to make sure our bearings are within specifications and will work properly once in service. Keep in mind, all measurement testing should be conducted after the bearing is press-fit into the housing. Prior to press-fitting, the bearing is oversized and may not conform to the listed specifications.

Bearinginstallation methods

While there are other tests that can be used to quality-check a bearing, problems can arise when applying these methods to plastic bearings. In particular, the use of a caliper should be avoided. Calipers, depending on the level of accuracy, are generally acceptable for only hurried quality checks. However, depending on the amount of pressure applied by the caliper or the location of the measurement, it is possible the numbers will not read correctly. It is a lot more reliable to use a pin-gauge test to avoid unforeseen problems.

While it may seem simple in the scheme of a large project, the manner in which a bearing is installed and quality tested is essential to the success of any mechanical system.If the installation of the bearing is not done properly or the quality-testing methods fall short, a variety of problems can arise. By following the installation tips outlined below and ensuring the proper quality checks have been performed, your bearings should work well from the point of installation.

When using a plastic bearing, a pin-gauge test works especially well because the peaks and valleys of the bearing are irrelevant as long as the recommended shafts are able to pass through the bearing. Over time, as the bearing’s self-made lubrication fills in the peaks and valleys of the shaft and the bearing, an ideal sliding surface is achieved.

Due to their ladder-style format, the preassembled shrink sleeves in the WMS... product family provide a good overview and facilitate quick use. After the printing and applying process, you have the option of shrinking the marked shrink sleeves by applying heat manually and thus fixing them on the cable/wire.
