Couplings & Bearings Manufacturing
COUPLINGS are used to couple or join shafts. There are two types of couplings: Permanent Couplings and Clutches. Permanent couplings are normally not disconnected except for assembly or disassembly purposes, whereas clutches permit shafts to be connected or disconnected at will. BEARINGS on the other hand, permit smooth, low friction movement between two surfaces. The movement of bearings can be either rotary (i.e. a shaft rotating within a mount) or linear (i.e. one surface moving along another). Bearings can employ either a sliding or a rolling action. Bearings based on rolling action are called rolling-element bearings. Those based on sliding action are called plain bearings.

We also manufacture our customers complicated shaft, bearing and housing assemblies, premounted bearings, bearings with seals for grease and oil lubrication.
- Premounted Bearings: These consist of a bearing element and housing. Premounted bearings are generally assembled to permit convenient adaptation to a machinery frame. All components of premounted bearings are incorporated within a single unit to ensure proper protection, lubrication and operation. Premounted bearings are available for a wide range of shaft sizes and a variety of housing designs. Rigid as well as self-aligning premounted bearings are offered. The self-aligning bearings compensate for minor misalignment in mounting structures. Expansion and nonexpansion bearings are available. Expansion bearings permit axial shaft movement and have applications for expansion units in equipment in which shafts become heated and increase in length at a greater rate than the structure on which the bearings are mounted. Nonexpansion bearings on the other hand, restrict shaft movement relative to the mounting structure.
- Grease and Oil Lubricated Sealed Bearings: For bearings to operate properly, they need to be protected against loss of lubricant and also entrance of dirt and dust on bearing surfaces. Housing seals for grease and oil lubrication include felt ring, grease grooves, leather or synthetic rubber cuff seals, labyrinth seals, oil grooves and flingers. More specific information on the various types of seals used in the broader spectrum of applications can be found on our page on mechanical seals by clicking here.
- Shaft, Bearing and Housing Assemblies: For ball or roller bearings to function properly, both the fit between the inner ring and the shaft and the fit between the outer ring and the housing must be suitable for the application. We assure that desired fits are obtained by selecting the proper tolerances for the shaft diameter and the housing bore. Bearings are generally mounted on the shaft or on tapered adapter sleeves. To hold the bearing inner ring axially on the shaft, we sometimes use a lock-nut and lock-washer. Depending on axial forces and their potential to displace bearings on the shaft we decide what method to use. Sometimes this is achieved by incorporating a shoulder in the design against which the bearing taking the load is pressed. It is impractical to mount bearings on long standard shafts with an interference fit. Therefore, we usually apply them with tapered adapter sleeves. The sleeves outer surfaces are tapered and match the tapered bores of the bearings inner rings. This assures a tight fit between the bearing’s inner ring and the shaft. Contact us and we will help you choose the right match of bearings, shafts and housing assemblies.
