  • Bearings

    Bearings (91)

    Bearings reduce friction between two objects, which allows moving parts to run smoother. They are divided into two main categories: thrust bearings and radial bearings. Thrust bearings support axial loads, which are parallel to the axis of rotation, while radial bearings support turning shafts perpendicular to the axis of rotation. Depending on the application, there is a wide range of…
  • Bushings

    Bushings (337)

    Bushings mount on the shaft of motors and other sources of rotational energy to transfer power and reduce vibration. There are keyless, quick disconnect, taper locking, and split taper shaft mounted bushings. Keyless bushings are used to fasten shafts and hubs without any backlash. They work well with smaller bearings and can be mounted to plain shafts without any oversize…
  • Chain and Chain Sprockets

    Chain and Chain Sprockets (1496)

    Power transmission chain and chain sprockets are used to transmit mechanical power from one rotating shaft to another. A chain drive consists of at least two sprockets and a roller chain that interlocks with the sprocket teeth. Chain sprockets with more teeth carry heavier loads but they produce more friction, which reduces operating speeds. Roller chain is lubricated to reduce…
  • Clutches and Brakes

    Clutches and Brakes (35)

    Clutches and brakes adjust the speed of rotating components. A clutch starts or controls the speed of a load through shafts that are connected in-line or parallel. A brake can stop, slow, or hold a load. Four methods are used to operate clutches and brakes: pneumatic, electromagnetic, mechanical, and hydraulic.
  • Couplings

    Couplings (2)

    Shaft couplings, collars, and U-joints join components and shafts together to transmit mechanical power. Shaft couplings join two shafts together to transmit rotary motion from one shaft to the other. They include elastomeric flexible couplings and fluid couplings. Elastomeric flexible couplings compensate for shaft misalignment and deformation and do not require lubrication. Fluid couplings use hydraulic fluid to transmit rotational…
  • Industrial Belts

    Industrial Belts (10359)

    Industrial belts are used to transfer mechanical power. They include V-belts, round belts, timing belts, and flat belts. V-belts have tapered cross-sections that allow the grooves to grip the V-belt pulleys to transmit high torque and reduce slipping. Round belts are used in pulleys with a 60-degree V-groove. Timing belts have external teeth that interlock with the teeth of timing belt…
  • Lubricants

    Lubricants (1)

    Industrial chemicals and lubricants and synthetic and petroleum based products used to reduce wear, prevent corrosion, or transfer fluid power. Hydraulic fluid or hydraulic oil is used in manufacturing and maintenance of machinery. Coolants are used in high-speed metal cutting operations to prevent rust buildup and corrosion on tool edges. Lubricants include grease, motor and machine oil, and multipurpose penetrants.…
  • Sheaves

    Sheaves (381)

    Power transmission belt sheaves or pulleys are used to transfer mechanical power. They include synchronous, timing, v-belt, variable pitch, flat, and round sheaves.  Timing sheaves have external teeth that interlock with the teeth of a timing belt to transmit high torque. Timing belt sheaves are commonly used in automobiles where the timing belt connects the crankshaft and camshaft to control engine valves.…
