超高分子量聚乙烯托辊（UHMWPE）是新一代以塑代钢的高新技术产品,其主要原料是超高分子量聚乙烯,并根据托辊表面材料的变化,对其制造结构也做了相应的改变,使其耐磨,转动等系数得到很大的提高,使其与金属托辊或陶瓷托辊相比，在使用性能上具有了诸多明显的优势。

  托辊使用寿命的延长，使得更换维修次数减少，即减轻了工作人员的劳动强度，又使设备的维护费用降低，并提高了使用效率。

  轴套是为了减少周运动是的摩擦与磨损而设计出来的，基本用途与轴承无异，而且相对成本较便宜。轴套多被放置与轴与承托结构中，而且非常紧贴承托结构，只有轴能在轴承上转动。在装配轴与轴套时，两者间会加入润滑剂以减少其转动时产生的摩擦力。

  Ultra high molecular weight polyethylene roller (UHMWPE) is a new generation of high-tech product replacing steel with plastic. Its main raw material is ultra high molecular weight polyethylene. According to the change of the surface material of the roller, its manufacturing structure has also been changed accordingly, so that its wear resistance and rotation coefficient have been greatly improved. Compared with metal roller or ceramic roller, it has many obvious advantages in service performance.

  The extension of the service life of the idler reduces the number of replacement and maintenance, which not only reduces the labor intensity of the staff, but also reduces the maintenance cost of the equipment and improves the use efficiency.

  The shaft sleeve is designed to reduce the friction and wear caused by the circumferential movement. The basic purpose is the same as that of the bearing, and the relative cost is relatively low. The shaft sleeve is mostly placed in the shaft and support structure, and is very close to the support structure. Only the shaft can rotate on the bearing. When assembling the shaft and shaft sleeve, lubricant will be added between them to reduce the friction generated during rotation.
