Installation Method of Single Row Deep Groove Ball Bearing Assembly

Although single row deep groove ball bearing components can be a simple installation on the shaft staying the same, and can be up and running immediately, however, if errors occur during installation, early damage is possible generally as rolling single row deep groove ball bearings. Therefore, single row deep groove ball bearing components must be carefully installed in the early time. At the time of installation, you must be careful not to give too much impact, be sure to pay special attention to the installation point, and then start the installation.

In the cylindrical hole single row deep groove ball bearings occasion, the inner ring and shaft, for installation purposes, generally coordinate with a clearance fit. However, in the necessary operation of high-precision and high-speed operation, or a heavy load or withstanding shock loads occasions, the inner ring and shaft combines for an interference fit.

In taper hole single row deep groove ball bearings occasion, because they are installed using an adapter sleeve, even if error of axis dimensions is slightly larger,there will be no problem. Again, in a lot of axial loads occasions, use the stepped shaft as far as possible, contact the inner ring of single row deep groove ball bearings with cylindrical bore with the ledge of stepped single row deep groove ball bearings to used.

First remove the connecting bolts when removing single row deep groove ball bearings. As the thread surface deposits a layer of grease, corrosion products and other sediments, the bolt is not easy to remove, particularly for Severe corrosion bolts, and removal is difficult. You must choose the right tools to disassemble bolt, because the outer hexagonal or hexagon of bolt has been slipping to damage so that removal becomes more difficult. For bolts has rust or with large number of grease, spray at the joining of bolt and nut with solvents (such as rust remover), let solvent goes into thread, so that they are easily removed.

In the removal process of single row deep groove ball bearings, the most difficult job is to remove wheel from the shaft. For key wheels, generally use three-pin puller or four-legged puller for disassembly. Puller should go with the dimensions of wheels, combination right angles hook of every feet of puller with the wheel back side must be suitable, slippage will not occur when putting forth strength. This method is only for relatively wheel removal of small interference fit, for wheels with larger interference fit, often use heating method, or together with hydraulic jacks to demolish.

In the removal process of single row deep groove ball bearings, the most difficult job is to remove wheel from the shaft. For key wheels, generally use three-pin puller or four-legged puller for disassembly. Puller should go with the dimensions of wheels, horses tied to the feet at right angles with the wheel back side with suitable, slippage will not occur when the force imagined. This method only for relatively small wheel removal of interference, interference fit larger wheels, often using heating method, or together with hydraulic jacks to demolish.

Cleaning, cleaning up and assessing quality all parts of single row deep groove ball bearings is a extremely important work after these ball bearings removal. Assessment means that each of the parts and components after operation, compared to the present state of its size, shape, and material properties and component design with the established quality standards, determine which parts can continue to be used, which parts should be repaired, and which should discard and replacenew ones.

Single row angular contact ball bearings and Tolerances

Angular contact ball bearings

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle α is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

SKF angular contact ball bearings are produced in a wide variety of designs and sizes. Those commonly used and included in this catalogue are
– Single row angular contact ball bearings

Single row angular contact ball bearings can accommodate axial loads acting in one direction only. Under radial loads a force acting in the axial direction is produced in the bearing, and this force must be counteracted. Consequently the bearing is normally adjusted against a second bearing.

Normally SKF single row angular contact ball bearings have one high and one low shoulder. Some bearings, particularly those of Diameter Series 8 and 9, have an inner ring with two high shoulders as in a deep groove ball bearing. The low shoulder on one or both rings enables a large number of balls to be incorporated in the bearing, thus giving the bearings a relatively high load carrying capacity. They are of non-separable design.

The contact angle α is 40°, designation suffix B, for the most common sizes. For larger bearings contact angles of 25° and 30° are the most common, designation suffixes AC and A respectively.

SKF single row angular contact ball bearings are produced in two versions
– basic design bearings (not universally matchable) – can only be used for arrangements with single row ball bearing
– bearings for universal matching.

The larger sizes are produced exclusively as universally matchable bearings.

– double row angular contact ball bearings
– four-point contact ball bearings

Dimensions

The boundary dimensions of SKF single row angular contact ball bearings are in accordance with ISO 15:1998.

Tolerances

Basic design SKF single row angular contact ball bearings for single mounting are produced to Normal tolerances. Standard design universally matchable bearings are manufactured to better than Normal tolerances.

SKF Explorer angular contact ball bearings are manufactured only as bearings for universal matching with P6 dimensional accuracy and P5 running accuracy.

Large bearings having an outside diameter of approximately 400 mm and above have dimensional accuracy to tolerance class Normal and running accuracy to tolerance class P6 as standard.

The values for tolerances correspond to ISO 492:2002.

Ball bearing

Bishop-Wisecarver Corp. (Pittsburg, CA) has announced The Radial Wheel, a single row ball bearing designed for applications with specified radial loading conditions. The wheel enables reliable motion in environments exposed to debris such as sawdust or grit. The bearings make it possible to convey heavy loads without additional capabilities unnecessary to the application requirements. The 90-degree vee-groove bearings work in finished products like sliding wall panels and motorized doors and windows.

The wheels come in carbon steel or stainless steel, and in three primary sizes with outside diameters ranging from 0.774 to 1.803″. All sizes can travel at speeds up to 5.5 meters a second. The custom- designed ball bearing was made for use with the 90-degree running surface of the vee edge track, a linear bearing raceway with polished running surfaces.
