A fixed axial and free axial bearing is general used for supporting shafts, while the fixed axial bearing provides shaft guidance in both directions and the free axial bearing compensation for the axial change in length and thermal expansion. If axial displacement of thermally expanding components is prevented, then uncontrolled axial overloading of firmly fixed bearings may result. Bearings that can carry combined loads are most suitable for capturing axial forces. Bearings that are best able to afford axial movement are NU and N roller-contact bearings (fig. 4.10). If ball or roller-contact bearings are used as free bearings, then one of the bearing rings (usually the outer) must be attached freely (fig. 4.11).

If the load application point lies outside of the bearing axis, then an overturning torque is created. The use of a radial double-row bearing or a double-row angular-contact ball bearing usually suffices for its transfer. The use of a par of single-row angular-contact ball bearings or tapered roller bearings installed back-to-back in pairs (into an “O”), however, are preferred (fig. 4.5).

A typical Solution consists of a lubricant reservoir, metering valve(s) and fluid regulator, and connecting fluid lines. The Lubrication Systems dispense from a variety of custom sized reservoirs or original material supplier containers. All equipment is supplied with hard and soft parts compatible with the fluid being dispensed. The metering valves deliver pre-set measured shots to consistently meet the application’s requirement.

Each type of bearing is characterized by specific properties unique to the given design and dimensions, which determine its suitability for the given type of application. Ball bearings for example are characterized by low friction and low noise. They are designed for translating medium-large radial as well as axial loads. They may be manufactured at higher precision enable them to operate at higher rpms. Due to their properties and affordability, they are among the most common types of bearings used. In contrast, spherical-roller bearings are designed for housings under high loads and are capable of compensating to a certain extent misalignments. They are thus particularly suitable for industrial use. It is thus important, when selecting the type of bearing, to consider various influences and to evaluate them according to their measure of importance for the given housing. The selection of a standard bearing is influenced particularly by:

In addition to thrust bearings, ball bearings or four-point ball bearings can be used for capturing axial forces (fig. 4.4).

ZKL Company provides a full range of unilaterally or bilaterally packed or encased roller-contact bearings. The bearings use contact (friction) packing (fig. 4.15) or are encased (fig. 4.16) using non-contact (touch-less) packing. Bearings with dual-side packaging are filled with plastic grease and do not require additional greasing during operation. The use of such bearings makes it possible to design economical and spatially undemanding housing. In other instances, care must be taken to monitor the structure of other components to prevent unwanted leaking of grease and entry of contaminants into the bearings.

One example is the ORSCO 170 series system. The ORSCO 170 series system is designed as a modular unit, for precision lubrication applications. Its integrated electrical control box provides the right amount of lubricant at the right time. The innovative injector stack design delivers a small metered amount of lubricant on a continual and controlled basis, resulting in significant cost savings by decreasing lubricant consumption, reducing product contamination and eliminating under/over lubrication. It can handle applications requiring large amounts of lubrication. A high injector cycle rate delivers nominal flows of up to 4 drops per second (at 2 Hz). Precision is maintained by precise injector outputs of either a half drop (0.015cc) or two drops (0.060cc) per cycle.

Automate dispensing process = More profit Chain with proper lube runs smoother = Less power draw Cleaner work areas with less housekeeping = Reduced health claims Consistent shot sizes = Extends chain life and reduces unscheduled downtime Timed lubricant delivery = Use less lubricant & reduce on-going costs

There are several types of automatic chain lubrication systems available: “Spray or Oil Mist” Systems, “Squirt” Systems, Automated Metering Valves & Pump Systems, and “Drip Feed, Oil Cup or Sight Feed” Lubricators. Each system will have advantages and disadvantages. It is up to the individual Plant and maintenance professionals to determine what works best for their specific application.

Combined loads are composed of simultaneously acting radial and axial loads. Axial load capacity of a bearing depends on the angle of contact. The larger the angle, the larger the axial load bearing capacity of the bearing. Larger axial clearance in single row ball bearings increases their load bearing capacity. Single and double-row angular contact ball bearings or tapered roller bearings are best for capturing combined loads (fig. 4.3a). Combined loads can also be borne by double-row spherical-roller bearings, thrust ball angular-contact bearings, and to a limited extent, also spherical-roller thrust bearings. Self-aligning ball bearings, NJ, NUP, or NJ roller-contact bearings and NU bearings with HJ attachment rings (fig. 4.3b) can be used for combined loads with a relatively small axial component.

These bearings are more easily installed and removed, if they can be taken apart. This particularly applies for bearings within a fixed housing. Separable bearings are also suitable for use where frequent installation and removal are required. A ring with roller-contact elements may be installed separately, irrespective of the second ring (fig. 4.13a – 4.13c).

An Automatic Chain Lubrication System is a cost effective way to limit wear and the costly problems it causes. In fact, proper lubrication can double or even triple the life of your chains. FLO carries a full range of chain lubrication systems, in drip, brush, spray and roller configurations, to extend chain life, cut downtime, save electricity and increase profits.

With regard to manufacturing inaccuracies and spindle deflections, mutual inclinations of bearing rings occur in the housing. This phenomenon should be expected and it is necessary to select bearings that compensate for the misalignment and installation inaccuracy. Self-aligning ball bearings (fig. 4.9a), two-row spherical-roller thrust bearings (fig. 4.9b), and spherical-roller thrust bearings (fig. 4.9c), are such types. The angle of inclination of such bearings depends on the type, size, and load. High rigidity bearings, such as roller-contact or ball bearings, can compensate for small misalignments, assuming that they are unburdened.

In certain circumstances, it presents as a limiting condition for the bearing design. In small-diameter housing, the single-row ball bearing is most often applied (fig. 4.6). Roller-contact, spherical-roller, and taper-roller bearings may optionally be used for large diameter shafts (fig. 4.7). Various types of bearings also allow for a variety of types with various bearing section strengths. Where there is limited space in the radial or axial direction, bearings with a suitable cross-section are selected (fig. 4.8).

FLO combines the ORSCO system with Anderol Baking Chain Oil 150, a high performance ester based chain oil designed for use in high temperature applications. It prevents wear and minimizes deposits with a natural detergency to maintain cleaner chains with fewer operational problems.

Friction creates heat, causing parts to expand. This leads to wear and the production of “wear particles” which turn into tiny cutting tools that cause chatter and vibration and generates heat. The result – mechanical failure, expensive equipment replacement, unscheduled downtime, lost production, safety hazards, environmental and cleanup problems and more.
