Key-Turn Heavy Duty Radius Belting

Key-Turn radius belting has all the characteristics of straight-line flat wire belts, with the additional capability of making right or left turns of up to 180 degrees (360 degrees for spiral systems).

Materials Available

  • Galvanized steel
  • C1050 high carbon steel
  • T-304 stainless steel
  • T-316 stainless steel
  • T-201 stainless steel


  • Reinforcing links strengthen outside edges.
  • Available in 0.062" or 0.090" thick T-304 stainless steel material.
  • One or two links may be placed on either edge.
  • Reinforcing links on both edges enable belt to be flipped for longer life.


  • Turning ability enables belt to avoid obstacles, operate in limited space, and eliminate troublesome transfers.
  • Elongated slots allow pickets to nest, giving the belt the ability to turn and also providing for easy and thorough cleaning.
  • Stainless steel Key-Turn belts are USDA approved for use in federally inspected meat and poultry plants.
  • H series sprockets for heavy duty belts are suitable for Key-Turn belts.

Turning Radius

  • Minimum belt turning radius is equal to 2.2 times the belt width, measured on the inside radius of the belt.
  • No maximum turning radius.
  • For tighter turns, two or more narrow width belts divided by a rail may be used.
  • Conveyor should be designed to include a straight run 3 times the belt's width before engaging sprockets after a turn.
  • Consult Keystone Manufacturing before using the belt in a non-powered turn situation, as this set-up can cause excessive strain.
  • Maximum allowable drive tension is 300 pounds.
  • For belt speeds above 15 feet/minute, maximum drive tension is reduced to 200 pounds.
  • Both load and return side belt supports should be either rollers or UHMW polyethylene to reduce friction to a minimum.
