产品消费标准的定位对每一个消费厂来说不是一成不变的，它要根据同类的竞争敌手的变化而不停进行调解，原质料代价的变化和产品利润率的调解也使得贩卖代价不停变化，由于输送带、托辊产品型号和规格十分多，每个消费厂的成本核算和贩卖代价的订定变得十分复杂，它必要多个部分配合配合才能完成，传统的手工盘算工作量大、慢、容易出错，已不能顺应现在疾速变化的市场。

Positioning products consumption standard for each consumer is not immutable and frozen plant, according to the change of similar competitors instead of mediation, raw materials price changes and product profit rate of mediation is make the sale price does not stop changes due to the conveyor belt, roller type and specification product cost very much, accounting for each plant and selling price of the consumption set becomes very complex, it is necessary to complete the matching of multiple parts, the traditional manual calculation workload, slow, error prone, has been unable to meet the rapidly changing market now.

它的防水、防尘，两端轴承位置的精度、外圆径向圆跳动、转动惯量、防腐蚀锈蚀、耐磨性等综合性能，都能给带式输送机的使用带来直接的影响。我国托辊行业仍有较大的发展空间

Its waterproof and dustproof, the accuracy of the bearings at both ends, the round, radial, round runout, rotary inertia, corrosion prevention, corrosion resistance, wear resistance and other comprehensive performance can bring direct impact on the use of belt conveyor. China's roller industry still has a lot of room for development
