Self Tracking Timing Belt

Self Tracking Timing Belt

Self Tracking Timing Belts combine steel reinforcement with welded or moulded V guides. Tracking Belts provide accuracy and linear drive. Self-tracking timing belts are made with two materials:

  • Wear resistant polyurethane
  • High tensile steel cord tension members.

Guide Profile


Tracking Guides are placed on the tooth side of the timing belt. Guides are intended to improve tracking, to reduce wandering (side to side movement).

Tracking Guide Profile generally include K6 [G6], K10 [G10] & K13 [G13], some special guides include K8 [G8], K12 [G12] & K15 [G15].

Listed are the standard sizes for urethane timing belts’ v-guide. These measurements pertain to molded and welded integral v-guides on PU timing belts.
For more alternative v-guide dimensions, materials and belt varieties, please reach out to our sales department.

Perfect Tracking

Achieving precise belt tracking without pulley flanges can be achieved by using timing belts equipped with a tracking guide and pulleys featuring a tracking groove instead of flanges. The standard tracking guides are trapezoidal in shape and are available in two sizes: 6 mm, 10 mm and 13 mm wide.

Most self-tracking timing belts available feature a uniform, serrated tracking guide. The serrations maintain belt flexibility, especially for small pulley diameters. Solid tracking guides are tracking guides that are welded onto the belt. Belt drives using self-tracking timing belts are preferred for applications requiring precise alignment.

  • What is belt tracking?

Belt tracking refers to the capability to sustain control over the intended path of a conveyor belt following its alignment and installation.
Ensuring proper tracking of a newly installed metal conveyor belt is crucial, as frequently, the alignment of a new belt differs from that of the previous one.

  • What is a timing belt with V guide ?

Timing belts equipped with a v-guide are primarily utilized for linear guidance, as well as in vertical and rotary drive applications.
A v-guide is fitted either by welding it onto the timing side of an existing timing belt or by extruding the v-guide during manufacturing.
