Shape of Slideways: With Diagram | Machine Tools | Industrial Engineering

Roller slideways (refer Fig. 11.15 (b)) are used to move heavy loads positively and accurately. In this system rollers retained in a brass cage are interposed between the sliding meers. This arrangement reduces the friction between the two meers of the slide because rolling friction is substituted for sliding friction.

The end of the assely carried a double-swivel head with the No. 40 taper spindle running in taper roller bearings and held in a 3-inch travel quill. Early versions of the overarm were fitted with a fine-feed handwheel that was not only awkwardly positioned but tricky to operate, being concentric with the spindle and moving the quill though a screw and nut.

Tapered roller vs angular contact ball bearings - Practical …

20/2/2009· Tapered roller bearings are well suited for lathe or mill appliions provided they are used within their limits. Bearings have a thermal reference speed that is based on how much heat the bearing generates in operation and for the same envelope dimensions, the angular contact bearing will have a higher speed.
