HSN Bearing Solutions For Vertical Roller Mills

Creation on:2025/09/12

Vertical mill bearing , also known as bearings for cement plants , bearings for pulverizers , bearings for vertical rolling mills , bearings for vertical roller mills and bearings for vertical grinding mills , mainly includes grinding roller bearings and gearbox bearings.

Major Manufacturers And Core Equipment

World-renowned cement equipment manufacturers include: FLSmidth, LOESCHE, Gebr. Pfeiffer SE, Polysius, UBE Machinery. Each company occupies a distinct market share, leveraging the technological advantages of its equipment.

There are many types of equipment used in cement plants, among which the equipment that uses bearings more frequently include: Kilns, Clinker coolers, Roller presses, Vertical grinding mills, Bucket elevators, Cement mills, etc. Among them, Vertical grinding mills use bearings most frequently.

VRMs use large, high-capacity bearings in two main locations: the grinding roller assemblies and the mill gearbox.

Common Bearing Types In Vertical Roller Mills

1.Grinding roller bearings

The roller assembly experiences extremely high radial loads (from the grinding pressure) and axial (thrust) loads. The following bearings are commonly used for this purpose:

Spherical roller bearings: These are designed to carry very heavy radial loads and moderate axial loads in both directions. Their self-aligning feature is crucial for handling shaft deflection and misalignment caused by the grinding forces.
Cylindrical roller bearings:Often used in conjunction with spherical bearings, cylindrical roller bearings can carry very large radial loads but no or very light axial loads. In some designs, they serve as the “floating bearing” to accommodate thermal expansion.
Tapered roller bearings:These can be used to handle a combination of both radial and thrust loads.

2.Gearbox bearings

The gearbox, which drives the rotation of the grinding table, also utilizes heavy-duty bearings to transmit power efficiently:

Cylindrical thrust bearings: Designed to handle very high axial (thrust) loads from the grinding table.
Tapered roller bearings: Used to accommodate both the heavy radial and axial loads.

Different companies have different design philosophies, so the bearing structures used in the same equipment components can vary. For example, in Grinding rollers, some designs use a combination of spherical roller bearings and single-row cylindrical roller bearings, while others use a combination of double-row tapered roller bearings and single-row cylindrical roller bearings. As shown below:

Since each cement plant may purchase different cement equipment, HSN has various types of bearings in stock to meet the bearing procurement needs of different cement plants.
