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 surface shape of the outer ring is available in arc type and cylindrical type. The arc-shaped outer ring easily absorbs shaft center deformation and 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: The packaging method for some models has changed. For d size ≤ 10, box packaging has been changed to bag packaging; for d size ≥ 12, blue box packaging has been changed to white box packaging. During the transition period, mixed shipments may occur, but this does not affect usage.

Dimensional Drawing

For non-separable roller followers, please refer to the table below (same as the specification table) for selection:

Application	Arc type		Material
Application	With seal	Without seal	Material
Standard type	C-NARTU	C-NARTR	Equivalent to SUJ2
Standard type	E-NARTUS	E-NARTRS	Equivalent to SUS440C
High load type	C-NARTV	—	Equivalent to SUJ2
High load type	E-NARTVS	E-NARTRVS	Equivalent to SUS440C

Outer diameter tolerance 0 to -0.05 mm

Types of materials
This series is available in both bearing steel and stainless steel.
Compared to bearing steel, stainless steel has stronger rust resistance and is suitable for clean rooms and other environments where oil contamination must be avoided.

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 detached or damaged. Therefore, during design and installation, it is important to minimize the occurrence of axial residual force.
As shown in diagram (1), non-separable roller followers are suitable for this scenario, while in diagram (2), separable roller followers are appropriate.

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

■ 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 is the value when steel with an applicable 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 multiplied to obtain 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.

Frequently asked question (FAQ)

Question: What material is used for this series of products? Also, is there any surface treatment?: Answer: The material used in this series of products is equivalent to SUJ2, and there is no surface treatment.
Question: What parameters should attention be paid to when selecting a product?: Answer: When purchasing products, you need to choose according to your own installation and use requirements, referring to the specification table.
The parameters that need special attention are: inner diameter, outer diameter, basic rated load, rotational speed limit, etc.
Question: Why does the side plate of the non-separable roller cam follower always fall off? Is it a defective product?: Answer: First of all, the side plate of the non-separable roller cam follower is pressed onto the inner ring and is not integrated with the inner ring. Therefore, it is easy to come off when subjected to axial force. Roller cam followers are designed to withstand radial force, so axial force should be avoided as much as possible in the initial design. In addition, it is important to distinguish between the application scenarios of the separable and non-separable types and select the correct model accordingly.
