What features do Mast Bearings have?

2019-06-13

1.Thick Outer Ring: Mast bearings operate at relatively low speeds. They travel along the rail as a track bearing (like a wheel) and consequently experience high loads. The outer ring (steel tyre) of a mast bearing is much thicker than a standard bearing, to enable this load to be transmitted.

2.Inseparable Design: The components of the bearings are held together to form an inseparable ‘wheel’.

3.Balls or Rollers: Due to the high loads, mast bearings usually have balls or rollers as their rolling element.

4.Seals: Mast bearings are usually to sealed to prevent the grease from escaping and to keep debris out. The seal can be rubber (RS) or metal (ZZ), or sometimes a combination of both (ZRS).
