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

Many of the rod ends sold by Ondrives Ltd, a UK based mechanical drives specialist, are available from stock for quick and easy deliveries, the company states.
The ranges encompasses both female and male versions with lots of different models available. These vary from a self-lubricating, tight fitting type with minimal clearance on the ball to free moving (high ball clearance) rod ends with either a bronze or stainless steel self-lubricating insert. Other versions include plastic materials, which are maintenance free and have high strength under impact loads. They also offer compensation for alignment errors and edge loads as standard. Due to the special Igubal material, they are therefore resistant to dirt, dust and lint and are available with a metal insert in the bore as a special.

Description of bearing types
Male, female or spherical bearings are ready-to-use mechanical components, based on the journal bearing principle.
These components are used in mechanical construction to transmit static or dynamic forces at different angles.
Male and female bearings are sometimes called tips or ends.
Spherical bearings are sometimes just called bearings.
The design of bearing components is governed by the DIN / ISO 12240 standard, which also specifies the overall and interface dimensions and with neighbouring mechanical components.
Bearing components can be self-lubricating or fitted with grease nipples.
Spherical bearings supplement ball bearings or other casings in slow movements. They are also ale to withstand high loadings because of the larger surfaces in contact..
The body of spherical bearings can be made from various materials: standard steel, high grade steel, stainless steel or aluminium

Rod ends DIN ISO 12240-4 (DIN 648)
Rod ends are some of the most frequently used linking elements in industry. These parts can be found everywhere where simple movements are required, e.g. linear pulling, pushing or even axle offset compensation. The linking technology specialist, mbo Osswald, provides a particularly wide application range with a whole assortment of different rod ends and pivoting bearings.

DURBAL heavy-duty rod ends with integral self-aligning ball bearings, Series BRM,BRF,PM,PF
This design is especially suitable for high speeds, large swiveling angles or rotating movements with relatively low or medium loads. Prominent technical features are the low bearing friction, sealing against rough dirt penetration by means of shields on both sides. Under normal operating conditions the rod ends are maintenance-free. A Grease nipple is provided for lubrication during rough service and maximum loads. To avoid incompatibility with the initial lubrication, we recommend lubricating with a calcium-complexsoap- grease or Polyrex EP2. A special heat treatment procedure matches the rod end housing raceway hardness to the antifriction bearings, ensuring the same time high stability with changing loads.

DURBAL heavy-duty rod ends with a integral maintenance-free spherical plain bearing, Series BEM, BEF, EM, EF
In many cases DURBAL heavy-duty rod ends with integrated spherical plain bearing serve their purpose. They are primarly used for small swiveling or tilting movements at low speeds. They stand out for their high loadability and can also be used for shock loads.The ball slides on a composite bearing shell consisting of a glass fiber-filled nylon/teflon component. This design ensures an absolutely maintenance-free rod end. DURBAL heavy-duty plain bearing rod ends have a slight initial stress and virtually no clearance. The composite material used has a favorable secondary advantage in that it absorbs any foreign particles and embeds them so that no damage can occur. The joint balls of DURBAL heavy-duty rod ends with integrated spherical plain bearings are hard chrome plated. This reliable corrosion protection ensures that the function of the rod end will not be affected by a corroded ball surface under humid operating conditions.

A new range of rod ends is now available from Rino Industries Ltd of Chesterfield, as featured in their new catalogue.
The range includes heavy duty rod ends with integral self-aligning ball or spherical roller and plain bearings in both male & female versions. They are available in either left or right hand threads with no price difference, surprisingly, between the two. They are also available in stainless steel, should the standard forged steel not be suitable for your application.
All of the range is virtually maintenance free & many feature long-time lubrication.

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.
