  • Hydraulic squeeze bushings lets shafts slide, lock, and slide
    of applications, especially machine tools. Type ASA squeeze bushings only resist axial forces. They are commonly used in fixturing and reciprocating shaft applications. For instance, a shaft might firmly hold a workpiece in place on a table until the part is machined. Removing pressure from

Common. causes of radial loading include misalignment of the. shaft when mounted or use of items such as pulley. and gears. Axial loading is the parallel force, or force. applied along the same direction
  • Hold it right there
    the screw. This lets the screw dig into the shaft, letting the collar resist torque and axial loads and not simply slide along the shaft. Unfortunately, the screw digging into the shaft raises a burr between the shaft and collar, making it difficult to remove or adjust the collar. Loosening the screw
  • How to make bearings last in electric motors
    because a minimum load is not maintained. Electric motors typically incorporate a locating and nonlocating bearing arrangement to support the rotor and locate it relative to the stator. Locating bearings position the shaft and support radial and axial loads, while nonlocating bearings handle radial loads
  • Know your thrust bearings
    Operating conditions and design constraints dictate which type makes sense. Thrust bearings support axial loads on rotating shafts. Designs range from simple, coin-sized flat washers in household appliances to sophisticated assemblies several feet in diameter for hydroelectric generators. Six basic
  • Angular-Contact Bearings
    One-directional thrust bearings can support heavy thrust loads in one direction, combined with moderate radial loads. High shoulders on the inner and outer rings provide steep contact angles for high thrust capacity and axial rigidity. Bearings with contact angles from 15 to 40 are available
  • Bearing Mounting
    For instrument bearings, certain special considerations should be emphasized: Accurate axial positioning of the shaft relative to the housing requires shoulders, snap rings, or bearing flanges. Diameter of a shaft or housing shoulder must be sufficient to ensure solid seating and support
  • What to look for in a servocoupling
    continuous helical cut about their OD spanning several rotations. They are highly flexible, transmit low bearing loads, and tolerate angular misalignment or axial motion. Parallel misalignment makes the coupling beam bend simultaneously in two directions, which develops high stresses and shortens
  • Cylindrical Bearings
    rollers. Both techniques require precise engineering to eliminate loading without introducing other problems. bearings have either a separable outer ring or separable inner ring and allow considerable axial movement of the shaft. They must be used with an axially locating bearing such as a ball
  • Spiral-Wound Rings
    are available for shafts and bores ranging from 0.46875 to 15 in. in diameter. Rings for shafts and bores ranging from 0.375 to 72-in. diameters can also be manufactured. Retaining rings fail in two ways: through shear, or from overstressing due to axial deflection. For shear failure to occur
