  • Available Bored-to-Size and MST® Bushed
  • Precision machined grooves available in single & double groove designs
  • Statically balanced (Dynamic balancing available)

QD Sheaves

Martin QD Sheaves offer reliable performance to keep your drive belts running smoothly with a range of bushing types or groove styles to meet any light or heavy-duty application.

Our direct supply chain to Martin’s US factories gives us access to the largest inventory of stock sheaves, a unique made-to-order service and quicker lead times than other European competitors.

  • QD Sheaves in 3V, and 5V Sections
  • Hi-Cap® Wedge – Stocked for 3V, 5V & 8V Belts
  • Available in 1 to 12 groove configurations
  • Statically balanced (Dynamic balancing available)
  • Detachable Bushing for easy installation & maintenance

Variable Pitch Sheaves and Pulleys

Our range of Martin variable speed sheaves enables designers and engineers to increase or decrease the speed of the driven machine. In doing so, they allow for variances in the amp draw of the motor to maximise efficiency and increase or decrease static pressure and air flow.

 

  • Stationary adjustable speed sheaves
  • Precision machined grooves available in single & double groove designs
  • Full range of popular bore sizes including keyway and setscrew
  • Statically-balanced with positive locking system (dynamic balancing available)

Spun Pulleys

CRP offers a range of spun steel pulleys including split, spun, stamped & welded/riveted, machined, and cast pulleys which are integrally fixed to OEM machinery.

Our systems approach with our OEM partners allows us to analyse the initial drive and take control of the entire belt drive system for smoother running and quality throughout.

  • Our range of Diameters vary from 2½” to 8½”
  • Bored, keyed or splined to your specification
  • Base steel spun pulleys coated and plated to OEM specifications
  • Fully Tested Drive System for reassurance

    Synchronous Pulleys

    TIMING BELT PULLEYS AND SPROCKETS

    Our range of Martin timing pulleys and sprockets are manufactured to extremely close specifications and are stocked in minimum plain bore, taper bushed, and QD bushed styles depending on size and pitch.

    Our pulleys are made in five stock pitches to handle a wide range of loads, speeds and applications at the highest possible efficiencies. Circular pitch (usually referred to as pitch) is a basic consideration in the selection of timing pulleys as with gear and chain drives.

    Bushings are priced separately and must be added to pulley price.

    • Available in imperial widths
    • Peripheral axial grooves for positive engagement with the belt mating teeth
    • Available Bored-to-Size in QD and Taper bushings with or without Flanges

    Automotive Pulleys

    IDLER PULLEYS

    To complete our drive systems, CRP offers a range of Dayco idlers and pulleys. Dayco has a global reputation for top performance idler and tensioner pulleys with the most advanced automotive technologies employed in the materials research, design engineering and manufacture processes.

    The use of finite element analysis maximises structural integrity for both plastic and steel pulleys. Pulleys with smoother surfaces and tighter dimensional tolerances translate into less vibration and therefore longer belt life. 

    • Lubricated ball bearings and formulated injection moulded glass-filled polymers for enhanced performance and strength.
    • Double high-temperature seals assure peak bearing performance the most critical element of a pulley’s service life.

    Tensioners

    Our Tensioners are used on serpentine belt drives that consist of a single belt powering most of the engine’s accessories. Designed to maintain constant tension on serpentine belt drives, the Dayco Automatic Belt Tensioner features the original flat spring design to provide less operating range variations in tension.

    This innovative design reduces the risk of premature accessory bearing failure, belt noise and slippage, and poor accessory performance caused by low tension after the belt begins to stretch and wear.

    Dayco Heavy Duty Tensioners are designed for heavy duty diesel engine accessory drive applications, the heavy-duty cast aluminium body and pulley arms translate into extra strength and durability

    • Engineered for higher torque and power pulses with damage-resistant cast aluminium spring cases
    • Our heavy-duty pulleys include dual permanently lubricated bearings
    • Steel pivot tubes provides additional strength for critical torque requirements
    • Thermoplastic rubber spring slot plugs for keeping out harmful contaminants
    • Lubricated nylon pivot tube bushing and spring bushing for quieter performance
