产品名称:推力滚子轴承
产品编号:29300 29400
所属类别:34
产品描述:推力圆柱滚子轴承主要用于重型机床、大功率船用齿轮箱、石油钻机、立式电机等机械中。
详细信息:
推力滚子轴承用于承受轴向载荷为主的轴、径向联合载荷,但径向载荷不得超过轴向载荷的 55% 。与其他推力滚子轴承相比,此种轴承摩擦因数较低,转速较高,并具有调心性能。
29000,型轴承的棍子为非对称型球面滚子,能减小滚子和滚道在工作中的相对滑动,并且滚子长、直径大,滚子数量多,载荷容量高,通常采用油润滑,个别低速情况可用脂润滑。在设计选型时,应优先选用;
80000型推力圆柱滚子轴承、90000 型推力圆锥滚子轴承和 AXK 型推力滚针轴承,可以承受单向的轴向载荷,它比推力球轴承的轴向载荷能力大得多,并且刚性大、占用轴向空间小。
推力圆柱滚子轴承和推力滚子轴承适用于转速低的场合,推力圆锥滚子轴承转速稍高于推力圆柱滚子轴承。
推力圆柱滚子轴承属分离型轴承,只能承受单向轴向载荷和轻微冲击,能够限制轴(或外壳)一个方向的轴向位移,因此可用作单向轴向定位。但其承载能力远远大于推力球轴承。滚子滚动时,由于滚子两端线速度不同,使滚子在套圈滚道上不可避免地产生滑动,因此,此类轴承的极限转速较推力球轴承低,通常仅适用于低速运转场合。
标准设计的推力圆柱滚子轴承采用车制金属实体保持架,根据用户要求,也可采用其它型式或材料的保持架。推力圆锥滚子轴承只能承受单向轴向载荷,能限制轴承单向轴向位移,故可用作单向轴向定位。与推力圆柱滚子轴承相比,承载能力大、相对滑动小,但极限转速较低。
产品用途
推力圆柱滚子轴承主要用于重型机床、大功率船用齿轮箱、石油钻机、立式电机等机械中。
Product Name: Thrust roller bearings

Category: 34
Product Description: Thrust cylindrical roller bearings are mainly used for heavy-duty machine tools, power marine gear boxes, oil rig, electrical and other machinery in the vertical.
Details:
Thrust roller bearings for main shaft axial load, radial joint load, but the radial load must not exceed 55% of axial load. With the other thrust roller bearings, such bearings lower friction coefficient, high speed, and with self-aligning properties.
29000, a non-stick bearing spherical roller symmetrical type, can reduce the roller and the raceway in the work of sliding and roller length, diameter, roller quantity, high load capacity, usually oil lubricated inpidual circumstances can be used for grease lubrication low speed. In the design selection should be preferred;
80000 Thrust cylindrical roller bearings, 90000 Thrust tapered roller bearings and thrust needle roller bearings AXK type, can withstand a one-way axial load, thrust ball bearings than the axial load capacity is much greater, and rigidity, occupies a small axial space.
Thrust cylindrical roller bearings and thrust roller bearings for low speed applications, thrust tapered roller bearings speed slightly higher than the thrust cylindrical roller bearings.
Thrust cylindrical roller bearings are separable bearings, can withstand axial load and a slight impact, to limit the shaft (or shell) of the axial displacement in one direction, it can be used as a one-way axial positioning. But its carrying capacity is far greater than the thrust ball bearings. Roller rolling, because the roller ends of lines at different speeds, the roller raceway in the ring sliding inevitably arise, so such bearing speed limit lower than the thrust ball bearings, usually only for low speed applications.
Standard design thrust cylindrical roller bearings with machined metal solid cage, according to user requirements, but also can be other types or material cage. Thrust tapered roller bearings can withstand axial load, one-way bearing to limit axial displacement, it can be used as a one-way axial positioning. And thrust cylindrical roller bearings, bearing capacity, sliding a small, but a lower speed limit.
Usage
Thrust cylindrical roller bearings are mainly used for heavy-duty machine tools, power marine gear boxes, oil rig, electrical and other machinery in the vertical.
