Automotivebearing roller manufacturers

The Ball & Roller Bearing Division (formerly the Ball & Roller Bearing Company) has a prestigious history of manufacturing bearings in Connecticut for over 110 years.  We manufacture a complete line of ball thrust bearings, cylindrical roller thrust bearings,  cylindrical radial roller bearings,  spherical roller bearings, and journal roller bearings.  In addition to our standard line of bearings, we provide design and manufacturing services for many “special” bearings built to our customers specifications.

We service both OEM and the industrial power transmission aftermarket, and market our products directly to manufacturers as well as through our nationwide system of distributors.  Diameters range from 1/2″ to 24″, in both English and Metric dimensions.  All of our bearings are made in our facility in Connecticut and comply with all ABMA, ABEC and RBEC specifications and tolerances.  All bearings are made using hardened and ground bearing steels, with machined bronze or steel used for rolling element retainers.

We also can supply your loose bearing ball requirements.  These balls can be supplied in accordance with the applicable Mil Spec with chemical and physical certifications if required.  They are available in all grades, sizes and materials, including chrome steel, stainless steel, carbon steel, brass, bronze, tungsten carbide, aluminium, K-Monel, glass, plastic and ceramic.  We stock a large inventory of precision sizing balls, ranging in size from 1/64″ to over 1″ in diameter and everything in between, carried out to as many as 5 decimal places.  Most are available for immediate delivery.

The installation height and tolerances of the iglidur®® bearings are dependent on the material and wall thickness. The moisture absorption and thermal expansion are decisive for the material. Bearings with low moisture absorption can be installed with a small bearing clearance. The following applies to the wall thickness: The thicker the bearing, the greater the clearance of the bearing must be.

We are an approved US Government bearing supplier and are fully compliant with all DFARS and Mil Spec requirements.  We proudly offer affordable bearings and assemblies to meet the unique requirements of the various service branches. These needs include everything from maintenance equipment to field artillery. We provide both standard and custom bearings, assemblies, and reverse engineering to the armed services.

The hole in the housing should be made with the recommended tolerance (H7) for all bearings and be smooth, flat and chamfered. The bearing should be press-fitted using a flat press. The use of centring or calibrating pins can cause damage to the bearings and bring a greater amount of clearance.

This results in different tolerance classes for iglidur®® bearings. With these tolerances, iglidur® bearings can be operated according to the installation recommendations over the respective permissible temperature range and in room humidity of up to 70 %. If higher humidity levels are present or the bearing is operated under water, materials with low moisture absorption are to be preferred.

iglidur® plain bearings are supplied ready for installation. The extensive product line makes it possible to use a standard dimension in most cases. If subsequent machining of the plain bearings is nevertheless necessary, the adjacent table shows the machining guide values. If possible, however, subsequent machining of the sliding surfaces should be avoided. Higher wear rate is most often the result. One exception is the B iglidur® M250, which is very well suited for subsequent machining. In other iglidur plain bearings, disadvantages of a sliding surface machining can be counteracted by lubrication during installation.

iglidur plain bearings are press-fit bearings, which are dimensionally oversized and pressed into a housing with H7 tolerance. This is not always done in an assembly line using suitable tools. The igus assembly aid flexibly and reliably accepts plain bearings for shaft diameters from 13–50 mm (PT-1350) and 6–20 mm (PT-0620) and even permits assembly using a hammer - simple and fast.

It is not usually necessary to use an adhesive to fit the bearing. If a bearing is likely to lose its firm fit on account of high temperatures, a more temperature-resistant plain bearing should be used. If, however, there are plans to secure the bearings with adhesive, it will be necessary to perform suitable tests in each case. It is not possible to simply transfer the successful results seen in other applications.

With the free igus® Fit calculator, you can quickly and easily calculate fits and tolerances in accordance with ISO 286. In addition to the maximum and minimum dimensions, the corresponding fit type is also displayed.To the fit calculator

iglidur plain bearings are press-fit bearings. The inner diameter adjusts itself only after the bearing has been press-fitted in the H7 housing hole with the recommended tolerance. The press-fit excess dimension can be up to 2% of the inner diameter. This ensures the secure press-fitting of the bearings. Axial or radial movements in the housing are reliably avoided.

iglidur® bearings are press-fit bearings for housings with an H7 unit bore. This press-fitting of the bearing secures the bearing in the housing on the one hand, and on the other hand the inner diameter of the plain bearing is formed as a result. The bearing is tested, installed in the hole with the smallest dimension, both with a dial gauge and with a plug gauge:

We pride ourselves with prompt delivery of precision, quality bearings.  Being a small manufacturer, we can be flexibile with our manufacturing schedule to provide you with the bearings you need within the time frame you require them.  We can offer you a level of service which you don’t usually receive from our larger competitors, such as shorter lead times, staggered deliveries, engineering and application advice, and no minimum order quantities.
