Types of the idlers to be manufactured: plain idlers of carrying run and return run, impact idlers, disc and cleaning idlers. The idlers are produced with inset or replenished lubricant.

Beating of idlers:

  • normal idlers— 1% D mm, acceptable V l 3.15 m/s;
  • precise idlers — 0.6% D mm, acceptable V l 4.5 m/s;
  • highly precise idlers — 0.3% D mm, acceptable V l 6.3 m/s.

Two-sided multistage reliable (radial clearance in labyrinth is 0.3 mm) protection and isolation of bearing assembly units from idler internal space, and sufficient quantity of lubricant in them.

Ability of replenishment or complete replacement of lubricant without idlers dismantling. Each idler running under load at assembly. Selection of idlers parameters taking into account the loads, modes and operation conditions, provides the operating life (5 years) of 90% idlers, minimal expenses for maintenance, low power consumption and prime cost of transportation.

Idlers service experience on cargo traffics (2-30 mln. tons per year) showed that life duration of the idlers reached 20-25 years at transportation of light materials at HPPs and 5-10 years at mining and processing integrated works at transportation of large-sized iron ore.
