圆锥滚子轴承
  SLZ—圆锥滚子轴承由机加工锥体内、外圈和圆锥滚子组成的轴承单元,常用作支 承轴承。能同时承受较大的径向力和轴向力,由于圆锥滚子数量而具有很高的动载荷和静载荷,轴承并具有高刚度,广泛用于汽车、机床、冶金机械、纺织机械、电动机、传动轴、齿轮箱等定位和支承处。

△结构形式

  该类轴承滚道结构呈锥体,故特别适于径向和单向轴向负荷或合成负荷,且负荷能力大。其接触角越大,轴向负荷容量越大。内、外圈是分离型的,可分别采用静配合安装。

△产品精度
  尺寸公差和几何精度按GB/T307。
  配套圆锥滚子精度等级Ⅲ级(国标JB/T10235)。

△材料
  滚针材料为GCr15轴承钢,淬硬HRC60—65。
  内外圈材料为GCr15轴承钢,淬硬HRC61—65。
  保持架材料为优质低碳钢。

△特殊说明
  内组件和外圈分离。
  组装容易,间隙可调整,需施加轴向预紧力。
  轴承一般配置设计见滚动轴承应用技术中相关推荐。

Tapered Roller Bearing

SLZ---tapered roller bearing is a bearing unit composed of machined tapered-inner & outer races and tapered rollers. It is usually used as supporting bearing, and can simultaneously bear bigger radial & axial force. Because of tapered-roller number, it has very high dynamic load & static load, and also high rigidity. It is widely used in lathe, metallurgical and textile machinery; motor, driving shaft, gearbox and other location & supporting location.

Types of Designs:
Raceway structure of this bearing shapes up tapered, therefore it is especially suitable to radial & single-axial load or combined load with great loading capacity. The bigger the contact angle is, the greater the axial load capacity. Inner and outer races are separated type and can be mounted through static coordination.

Product Precision Accuracy:
Dimensional tolerance and geometrical accuracy is based on GB/T307.
Matched tapered roller precision grade is Ⅲ (ISO JB/T10235).

Materials:
Material for needle roller is GCr15 bearing steel, quench-hardening HRC60---65.
Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65.
Material for cages is quality low-carbon steel.

Special Directions:
Inner components and outer rings are separated.
Easy to be mounted, gap can be adjusted, and axial pre-tightening force is to be exerted.
For general-disposition design of bearings, refer to the relevant recommendation in the applied technology of rolling bearings.
