  • Shaft Loading and Sealing vs. Bearing Life Expectancy
    to. consider - radial and axial. Radial loading is the perpendicular. force applied. to the shaft. 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
  • No 6 Cement Mill Gearbox Input Pinion Bearing
    ' was on the Drive Motor Bearings. The Bearings had been leaking oil, so new sealing gland was fitted and the only gland packing available was Graphite based so this was used. It was agreed to purchase new bearings for the Input Shaft (24148 C the problematic axial bearing and 23052 C the gear load bearing
  • 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
  • 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
  • Ball-screw rigidity is a matter of definition
    thousand Newtons, though the shaft elastic displacement is only a few microns. Stiffness or rigidity is a key factor in evaluating ball-screw drives for specific needs. Rigidity, in this context, describes a ball screw's elastic deformation under load and directly affects the precision of an axis drive
  • 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
  • A few guidelines for fitting miniature bearings into assemblies
    The upper curve in the chart shows a single-bearing deflection curve. When two bearings are preloaded together and subjected to an external thrust load, the axial yield rate for the pair drops because of the preload, the interaction of the forces exerted by the external load, and reactions
  • Precision coupling "shock proofs'' innovative packer
    the Zero-Max CD coupling between the servomotor and speed reducer. Zero-Max CD Double Flex couplings handle misalignment up to 3 angular, 0.137-in.. parallel and 0.5-in. axial, depending on size. They come in 1.85 to 12-in. diameters and handle up to 47,200 lb-in. of torque. A durable composite disc
  • 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
  • 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
