Introduction

 High quality roller, suitable for long distance, large amount of transportation, high belt speed, bad working environment, especially high requirements of the conveyor, indoor and outdoor all the year round can, wide range of application.Service life over 30000 hours.the tube is a seamless tube for idlers. the wall thickness is 3.25mm to 5mm, the ovality is 0.25mm to 0.4mm, and the radial runout of the idlers produced is less than 0.5mm.

 

Features

1) the pipe is a special welded pipe for the roller, the ellipticity is between 0.4mm and 0.6mm, and the radial runout of the produced roller is 0.7mm or less.

2) shaft is a cold drawn bar for high-precision rollers, which has good corrosionresistance, strength and hardness.the diameter is 0.01mm larger than the inner diameter of the bearing, and the tolerance is only >0.01mm, which ensures the tight fit of the bearing inner sleeve and the shaft to make the bearing rotation more stable.
