Pillow Block Bearings


如今,涉及直线运动应用的机床制造商通常不会寻求最快速、最廉价或者最高负载的解决方案。现在需要的是安装成本与性能的最佳平衡。找到枕块式轴承与导向轴的最佳配置可以实现这一点。

圆形导轨枕块式轴承相比方形导轨的优势包括:自对准和降低平行度的更大公差范围。枕块式轴承可安装在连续支撑或者末端支撑中。这些轴承可承受弯矩荷载;提供低阻力和卓越的平滑性。与方形导轨轴承相比,枕块式轴承更便宜、更易于安装,且在重要性能方面不作任何妥协。

Thomson提供世界最大、最可靠的枕块式轴承,包括Super Smart、Super、Precision Steel、Multitrac、FluoroNyliner系列,可实现各种各样的高性价比选项。枕块式轴承可作为完整组件或者改装套件提供。

该系列中的一个新产品是终身润滑枕块式轴承,无需常规的轴承润滑保养。自润滑油盒被压入枕块式轴承外壳两端,可提供连续的轴承润滑并增强防护性能,用途十分广泛。

在食品级型号中还可选用新型永久润滑高分子聚合物,尤其适合安装在Thomson新型轻质铝合金精密导向轴上的FluoroNyliner枕块式轴承。

得益于各种各样的标准产品选择,以及我们快速修改标准产品和完成定制化解决方案的能力,我们的枕块式轴承还承诺“完全匹配”的解决方案。当在现场进行新应用时,Thomson可靠、快速的轴承交货可使您安心。请联系Thomson客户支持部门,对您的应用进行综合评价。

Lube for Life Pillow Block Bearings

Thomson Lube for Life pillow block bearings provide continuous bearing lubrication and enhanced protection for a broad range of applications. Self-lubricating cartridges are pressed into each end of the pillow block housing, and the linear bearing is lubricated initially with EP2 grease. The Lube for Life polymer is under constant pressure against the 60 Case shafting, ensuring a film of lubricant between the ball bearings and the inner race. The Lube for Life pillow block bearing is available as a complete assembly, or in a retrofit kit for existing non self-lubricating pillow block assemblies.

Super Metric Ball Bushing Bearings

Thomson pillow block bearings with factory-installed Super Metric Ball Bushing Bearings offer accelerations as high as 150 m/s2 and steady state travel speeds up to 3 m/s without the derating factors commonly required with linear guides, and the twin version with two Super Ball Bushing bearings provides twice the load capacity or 8 times more travel life than the single version.

Super Smart Ball Bushing® Bearings

Thomson pillow block bearings with Super Smart Ball Bushing® bearings offer advanced technology features, including up to 6 times the load capacity or 216 times the travel life of conventional linear bearings and permits the up-rating of existing designs. This high load capacity permits cost reduction through the use of smaller and less expensive bearings and 60 Case LinearRace® shafting.

Precision Steel Ball Bushing Bearings

Precision Steel Ball Bushing bearings offer great improvements in efficiency, productivity, and accuracy over high-friction plain bearings flat-ways. The all-steel design makes the bearing product line perfect for replacing plain bearings in high temperature applications. Rigid construction makes them very durable compared to ball bushing bearings with polymer components. When installed in a standard Thomson Pillow Block, the Precision Steel Ball Bushing bearing can self-align up to 3° in all directions.
