Cam Follower

GET A QUOTE ANY QUESTIONS

Cam followers, also called stud type track rollers, are special roller bearings that are mainly used to follow tracks or cams and are used in a wide range of applications in linear motion systems. We often see cam followers in conveyors and industrial transmission lines, such as in the food and beverage industry, the plastics manufacturing industry, the glass manufacturing industry, and others. As one of cam followers manufacturers, we will try our best to meet customers' needs.

Technical Information of THB Cam Followers

Lubrication

THB cam follower has been filled with lithium-based grease and can be re-lubricated through the special oil hole for the bolt shaft. Equivalent grease can be used for re-lubrication.

THB can also provide targeted lubrication programs, if necessary, please contact the THB technical department

Working temperature

Limited by the grease and sealing material, the KR, KRV, and KRE series are suitable for an operating temperature range of -30 °C to +100 °C

Sealing

Cam followers have seals on both sides. For the sealing form, please refer to the corresponding parameter table.

Seal model description:

2RS	Lip seal on both sides of the yoke type track roller.
2Z	Metal shield on both sides of the track roller bearing.
2RSR	Radical contact lip seal on both sides of the yoke type track roller bearing.
2ZL	Sealing shield with lamellar rings on both sides of the track roller bearing.

Features of Cam Follower

High radial load, can withstand combined loads, long life, easy to install

High radial load: the thicker wall outer ring not only withstands high radial loads, but also reduces deformation and bending stresses when working as a roller.
Axial loads can be sustained: cylindrical roller bolt shaft rollers with baffled edges can withstand axial loads that may result from off-loading or inclined operation.
Long service life: The convex design of the outer ring surface can be greatly improved where the outer ring may be inclined in relation to the working track surface or where edge stresses need to be minimised.
Easy to install: The design of the bolt shaft construction allows for quick and easy installation of the bolt type roller onto the corresponding machine component with hexagonal nuts.

Applications for Cam Followers

Cam drives	machine slides	material transport
metallurgy	mining equipment	railways
agriculture	construction
