Induction shrink fitting

Induction shrink fitting refers to the use of induction heater technology to pre-heat metal components between 150 C (302 F) and 300 C (572 F) thereby causing them to expand and allow for the insertion or removal of another component Typically the lower temperature range is used on metals such as aluminium and higher temperatures are used on metals such as low/medium carbon steels

Tapered Roller Bearings

Tapered roller bearings consist of four basic components including: the cone (inner ring) the cup (outer ring) tapered rollers and a cage (roller retainer) The cone cup and rollers carry the load while the cage spaces and retains the rollers on the cone The cone rollers and cage components of our tapered roller bearings are referred to as the cone assembly

Bearing preload: What is it and why is it important

Jun 11 2019If the bearing has a tapered bore the bearing is driven onto the taper resulting in an interference fit This causes the inner ring to expand and exert a radial force on the rollers to create the proper preload Preload methods The two main methods of bearing preload are rigid and spring
