PRESSURE ROLLER BEARINGS
These are stainless steel radial bearings with Urethane rubber fixed by special processing on its outer ring to keep its rotation accuracy. Under the proper radial loading, the coefficient of friction and hardness of rubber are useful for handling paper or for carrying mechanisms, guide bearings and idle bearings.
Size range from 3x10x4 to 6x24.5x5 mm
2 shields, Nippon NIGACE Grease lube.

Since the creation and patenting of the original DualVee® wheel in 1967, it continues to provide easy to use, easy to install guide wheel components and assemblies. DualVee is ideal for a wide array of applications, from the clean room to the sawmill. These rugged yet economical guide wheels are quiet, ideal in long length applications, and tolerant of harsh environments.
DualVee's recirculating elements are self-contained and isolated from the environment; rolling contact between the wheel and track sweeps debris aside, making it ideal for use in contaminated environments.
DualVee offers three different wheel options; original guide wheels, studded guide wheels, and new integral one-piece guide wheels for lower cost and ease of installation. A wide variety of bushings and journals are available.
DualVee single edge or double edge track with patented mounting shoulder is available in carbon steel or stainless steel, induction hardened or "as formed". Hardened track comes in single lengths up to 20 feet, unhardened in lengths up to 22 feet. Track is easily butt-jointed for longer length applications.
A number of accessory items are also available including wheel covers, lubricators, track plate assemblies and wheel plate assemblies.

A highly effective system for lower cost and accuracy builds up from a single edge track and matching wheels. DualVee components are available in a range of sizes to suit most applications with high temperature and vacuum/clean-room options available to complement existing stainless steel components.
- Track lengths up to 6m with unlimited lengths achievable by butting
- Available drilled or un-drilled to minimise additional engineering
- Ex-stock availability

Track rollers are self-retaining, single or double row units with particularly thick-walled outer rings. These bearings can support axial forces in both directions as well as high radial forces. The bearing outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where there is misalignment in relation to the raceway and edge stresses must be avoided. The track rollers are available with an inner ring, with a stud and with a plastic tyre on the outer ring.

- Rotated parts of the rollers are in polyurethane 90° Sh. A equiped with a double lip dust seal.
- Stainless steel or other connection desgins will be considered on request.

Super-finished raceways of the Modern Linear guide rollers offer superior performance to competitors' product. Smoother raceways translate to smoother and quieter operation in linear applications.
Modern Linear guide rollers are designed to replace existing rollers in linear applications. They are dimensionally equal to existing Dual-Vee and Schatz guide wheels. Our rollers incorporate a 90 degree groove angle and will run on existing track.
Compression resistant plastic rollers can be used with adapter bushings and aluminum rail.

The Diabolo rollers are special arranged in the meat hook that running on a long tubular rail in the Abattoirs. These rollers feature to accept high carrying loads and to have long service life. The rollers have different hardness in external profile surface and internal structure so that the rails are prevented from wear in operation. These rollers are filled with high-grade grease which can run in the range - 40°C to + 180°C with waterproof & anti-washing function.

YTGW Guide Wheels are the main components of the Linear Motion system, they can be widely used in the industrial robot, cutting machine, motion track, production flow and so on.
The surface of outer ring is the "W" profile formed by the two "V" with an angle of 90 degrees. The internal or external side face can be matched separately with the concave or protrudable track that both have a "V' profile with the angle of 90 degrees, and also the internal side face can be matched well with the cylindrical track.
Wheels feature the internal design of double row angular contact ball bearing and a thick-walled outer ring, so the wheels can accommodate higher loads.
Wheels are made of the high-quality bearing steel, processed by heat treatment and precision grind, and are filled with a long service life, high-grade and multi-purposes grease. Wheels mantle the metal shield or rubber seal (suffix X) to prevent the dust. YITONG also can provide the wheels with the concentric or eccentric bushings, as well as the wheels made from the corrosion resistance stainless steel.

Wire Guides and Straightening Rollers - type A or AT
Field of Application :
The straightening of cables, strips and wires is performed in steps with successive stages until the final product is obtained. To rationalize the handling between the different steps the material is stocked on reels or on bobbins and takes forms which are not natural.
For every production step, it is therefore necessary to carry out the inverse process by taking the material off its support. At that moment, the straightening operation takes place. It may be divided into three steps:
The straightening, consisting of putting the material back into its original shape. The operation is carried out by the first straightening rollers.
The removal of the residual constraint in the material, due to the winding on the bobbin. This operation is performed by the rollers located in the central part of the straightener.
The forming of the wire carried out by the last rollers on the straightener, generally placed at an angle of 90°compared to the angle of the first rollers.

Track rollers with Gothic arch groove - type SG
The function of series SG rollers is same as the series LFR rollers. But they are mainly used in the flat track and in the condition required compact structure. After rollers are installed to the slider, the shaft will be not or seldom over the roller's side planes.

DURBAL heavy-duty rod ends with integral self-aligning roller bearings, Series BRTM, BRTF
The design based on the structure of a self-aligning roller bearing is preferably used for high speed, large tilting angles or rotating motion with medium loads. Compared to rod ends with selfaligning ball bearings, rod ends with selfaligning roller bearings have essentially higher basic load ratings. This design is equipped with a cage to minimize the rolling friction and heat built-up. These rod ends are under normal operating conditions maintenance-free. A Grease nipple is provided for lubrication in case of rough operation and maximum load. To avoid incompatibility with the initial lubrication, we recommend lubricating with a calcium-complexsoap- grease or Polyrex EP2. Shields on both sides prevent dirt particles from penetrating into the bearing. The rod ends with selfaligning roller bearings are, just as the design with self-aligning ball bearings, subjected to a special heat treatment procedure to match the racway hardness to the antifriction bearings, ensuring at the same time a high stability with changing loads and temperature.
