Product Overview
The roller follower is a compact, highly rigid bearing system. It can be used as a guide roller for cam disks and linear motion.
Since its outer ring rotates while being in direct contact with the mating surface, it is designed to withstand impact loads.
In addition, the outer ring is equipped with precision needle rollers (standard type) with a cage, providing excellent rotational performance and enabling high-speed rotation.
Roller followers are divided into two types: separable type (the inner ring, outer ring, and retaining ring can be separated) and non-separable type (the retaining ring is pressed onto the inner ring and cannot be separated).
The outer ring comes in two shapes: spherical and cylindrical. The spherical outer ring is better at absorbing shaft center deformation, which helps reduce offset loads.
These products have a wide range of applications, such as cam mechanisms in automatic and special-purpose machine tools, various handling devices, transfer devices, bookbinding machines, tool changers in machining centers, pallet changers, automatic painting machines, and sliding forklifts in automated warehouses, among others.
 



  Note: For some models, the packaging method has changed; for d size ≤ 10, box packaging has been changed to bag packaging. During the transition period, mixed shipments may occur, but this does not affect usage.

Usage Method
The structure of the roller follower is designed to withstand radial loads. When subjected to axial loads, the side plate and outer ring may become dislodged or damaged. Therefore, it is important to minimize axial residual force during design and installation.
As shown in scenario (1) below, use a non-separable roller follower; for scenario (2), use a separable roller follower.
Note: When the side plate of a non-separable roller follower is subjected to axial force, it may shift or fall off. Please refer to the above diagram and select the appropriate model according to the application scenario.

■ Installation
1. When designing and installing, pay attention to dimension a in the diagram below.

2. When installing as shown below, make sure that the oil hole of the inner ring is not positioned in the load area; otherwise, it may shorten the service life to some extent.

3. If there is poor contact between the outer ring and the mating surface, it is recommended to use an arc-type roller follower.

■ Track load capacity
Track load capacity refers to the allowable load that the roller follower's outer ring can continuously withstand over a long period when in contact with the mating rail, without causing deformation or indentation of the rail.
The track load capacity listed in the parameter table refers to the value when steel with a tensile strength of 1.2 kN/mm² is used as the mating material. Therefore, when the hardness of the mating rail is not 40 HRC, the corresponding coefficient in the table below should be applied to determine the correct allowable track load.


■ Dust Protection and Lubrication
1. The lubrication interval depends on operating conditions. As a general guideline, for standard types, replenish grease every 6 months to 2 years; for high-load types, replenish grease every 1 month to 6 months.
2. Even for products equipped with seals, excess grease may leak out during the initial operation phase or after replenishing the grease. If you wish to prevent grease from contaminating the area around the equipment, you can perform a trial run in advance and then wipe off any leaked excess grease.
3. As the usage time increases, the properties of the grease deteriorate and its lubricating performance decreases, so it is necessary to inspect and replenish the grease according to the frequency of use.
 
Precautions
1. Do not disassemble any parts, as this may cause functional damage.
2. Do not drop or strike the roller follower. Otherwise, this may cause scratches or damage. Additionally, even if there is no visible damage after an impact, functional damage may still occur.
