Adapters

Precision molded, one-piece, thermoplastic body (glass reinforced nylon) pulleys offer these advantages over two piece, metal pulleys:

  • Lower coefficient of friction reduces wear, increases belt life, lowers maintenance costs.
  • Thermoplastic resists oils, solvents, many acids, and is fully corrosion resistant.
  • One piece, molded construction pulleys are immune to rivet fatigue and separation that is often found in two piece metal pulleys.
  • Pulleys are precision molded concentrically around bearings, +/- 0.007 T.I.R.
  • All bearings are sealed A.B.E.C.-1 with sintered metal hubs.

Plastic Pulley Benefits

Our Products

Retlaw Industries produces high-quality thermoplastic products suitable for a wide variety of applications. Our inventory of components includes:

  • Idler Pulleys – Simple mechanical devices used to control motion and transfer energy via belts, chains, rope or cables. Its mechanical advantage depends largely on its circumference.
  • Sprockets – mechanical devices used to impart driving force on or control motion of a belt or chain where slippage is unwanted. Unlike pulleys, the mechanical advantage lies both in its circumference and ratio of teeth
  • Adapters – inserts into the center of the pulley or sprocket and used as an intermediary between the rotating shaft and the pulley. Drive adapters transfer power from the shaft to the pulley

Composite Thermoplastic Idler Pulleys

We produce dynamic and durable pulleys in a variety of styles to accommodate your needs. With the bearings molded in, our pulleys withstand high speeds and temperatures. Retlaw plastic pulleys have reduced surface friction and cause less belt wear than conventional pulleys. Our idlers don't corrode or suffer rivet fatigue because of the monolithic design encapsulating the bearing during the molding process.

Our idler pulleys come in an array of sizes and styles including:

  • Flat – a common pulley with a uniformly flat center channel
  • V-Belt – the center channel tapers inward for greater control over lateral belt shifting
  • Round Belt – the curved channel is ideal for controlling lateral shifting of round belts and ropes
  • Cable – effective in use with steel cables, has a smaller channel radius than round belt idlers
  • Flangeless – often used in conveyor belt applications, these idler pulleys have no central channel, hence the lack of a flange. Ideal for extremely stable, wide belts

Power Transmission Roller Chain Sprockets

Our plastic molding specialists produce low-power transmission sprockets resistant to most oils, solvents, chemicals and corrosion. Retlaw sprockets come in a variety of sizes with anywhere from 19 to 12 teeth and fit chains sized #35, #40, #50, #60, and #80.

Idler Pulley Adapter Styles

Pulley adapters, sometimes called bushings, change the compatibility of any given sprocket or pulley to fit the drive shaft on which it is applied. Proper application of our pulleys or sprockets is essential to their operation and reliability. With such a wide array of uses and styles, adapters are required to, well, help the pulley adapt.

Retlaw Industries stocks a wide range of sizes and several styles of adapters, including:

  • Drive Adapters – these are built with an integrated keyway to engage the rotation of the drive shaft and come with a 10-32 Nylock Set Screw to add wedging pressure
  • Standard Bore Adapters – a common pulley adapter, these fit flush with the center of the pulley and provide no lateral separation on either side
  • Shoulder Adapters – extend laterally on the shaft past the pulleys bore, providing spacing one side of the pulley
  • Clevis Adapter – extends laterally on both sides of the bore, providing spacing on each side of the pulley

The types of adapters available are as wide ranging as the types of pulleys and their uses. With the amount of thermoplastic product combinations available, you’ll find the pulley system you need at Retlaw. If you don’t, we will work with you to come up with a practical and efficient plastic design to meet or surpass all of your expectations.
