Series And Varients Of THB Cam Rollers
Types of THB Ball Bearing Track Rollers
The cam rollers provided by THB have two types, single-row ball bearing track rollers and double-row ball bearing track rollers.
Single-row products include the following models: LR6, LR60, LR2;
Double-row products include the following models: LR50, LR52, LR53.
There are several types of cam rollers: cam roller with inner ring, cam roller with support bolts, and cam roller with plastic cover on the outer ring. The cam roller constructions include outer ring, inner ring ball and nylon cage assemblies with crowned or cylindrical outer surfaces.
Size Range of THB Ball Bearing Track Rollers
The size range of single row ball bearing rollers is: inner diameter 4-45mm, outer diameter 13-90mm, width 4-19mm
The size range of double row ball bearing rollers is: inner diameter 5-40mm, outer diameter 17-100mm, width 7-36.5mm

Technical Information of THB Cam Rollers
Sealing
Ball bearing track rollers are sealed on both sides.
Sealing 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. |
Lubrication
THB Ball track bearing rollers are filled with lithium-based grease at factory. In some cases, double-row ball rollers can also be re-lubricated through lubricating holes in the inner bore surface.
THB can also provide targeted lubrication programs, if necessary, please contact the THB technical department.
Working temperature
Due to restrictions on the grease, retainer materials and seal materials, ball bearing
track rollers are suitable for the working temperature of -20°C to +120°C
Higher radial load, high speed capability, long life.
High radial load: thicker wall thickness of the outer ring can not only withstand high radial load, in working as a roller, but also reduce deformation and bending stress.
Can withstand overturning moment: double row ball roller bearings can withstand greater overturning moment compared to single row ball roller bearings.
Long service life: the convex design of the outer ring surface can be greatly improved to cope with possible tilting of the outer ring relative to the working track surface, or to minimize edge stress.
Relatively high speed capability.
