Track rollers for Vee bars/Plain rollers - type FR/LR
The backlash setting and the pre-tensioning of the rollers takes place via the eccentric hub of the rollers of the series FR.., FR..R or LR.., LR..R.
The FR..Z and LR..Z series are the concentric models. In the eccentric rollers, the inner bolts are provided with two holes. These allow for the adjustment of the backlash. If a roller is located in its zero position, the teeth backlash will be the standard value of 0.05 mm flank clearance.
The service life of the system will be reduced by excessive tensioning. With too little tension the rollers will not run, or will wear due to the poor meshing.

Linear guidance systems with linear recirculating ball bearing units comprise ball bearing units, carriages and guideways. They allow large support distances, have adjustable clearance and are to standard accuracy class G3.
The full complement bearing units run on one or both sides of the guideways and, despite their small dimensions, have high load carrying capacity. If the bearing units are screw mounted in carriages, together with the guideways they form four-row linear recirculating ball bearing and guideway assemblies. The ball bearing units are sealed on all sides by the wipers on the end faces and on the sealing strips which form a gap seal in conjunction with the guideway. Linear recirculating ball bearing units can be relubricated.

Linear bearings offer an easy and economic solution for unlimited linear motions.
Three different types are available:
• Linear bearings with closed design for applications with short strokes and loads from different directions
• Linear bearings with slot and clearance adjustment
• Linear bearings with open design for applications with high and one-sided loads
Whole linear bearing units, partly with several linear bearings one behind the other and with different designs complete our product range.
There are linear bearings made of plastic with load bearing plates of hardened steel or linear bearings with steel body, in standard material or corrosion resistant, with or without sealing, in sizes 2 – 150 mm.
We certainly find the right linear bearing for your application.
Advantages of our linear bearings:
• Easy replacement
• Economy installing
• Self-adjusting for bended shafts
• Smooth running
• High speed applications with high acceleration

Universally self-aligning these bearings offer a dual track design and load capacities up to 7,760 lbf (30,000N).
* Dual Track Design and load capacities up to 7,760 lbf (30,000N): up to six times the load capacity or 216 times the travel life of conventional linear bearings. That’s twice the load capacity or eight times the travel life of industry standard Thomson Super Ball Bushing bearings.
* A precision super furnished, dual track bearing plate for optimum system smoothness and performance.
* A universal self-alignment feature which compensates for misalignment of housing bores and 60 Case LinearRace shaft deflection, optimizes load distribution between ball tracks, and assures uniform ball loading over the entire length of the bearing plate, minimizing installation time and cost while bearing performance and life is maximized.
* A technologically advanced design that allows the bearing to maintain its diametrical fit-up when installed in housing that is slightly out-of-round.
* Longer travel life and minimal machine downtime when replacing conventional linear bearings or the industry standard Super Ball Bushing bearing.

Aerotech air bearings are perfect in semiconductor equipment, fiberoptics, photonics, and other critical industrial automation applications. Our air bearings incorporate an active preload on both vertical and horizontal surfaces. Opposing thin-film pressure maintains the bearing nominal gap tolerance. This design, in addition to the large air bearing surface that distributes the load over a large surface area, results in outstanding stiffness that is ideal for heavy or offset loading.

Product Overview
Recognized by engineers and industrial users for their long life, sleeve bearings are offered as an available option on all TITANÒ horizontal ODP, WP-I and WP-II enclosures. Sleeve bearings operate on a
thin film of oil supplied by oil ring or flood lubrication and are frequently applied to high(er) speed direct connected loads. Sleeve bearings have a very limited capacity for any external radial loads, but when applied and maintained correctly, they offer an infinite (theoretical) life.
U.S. Motors offers a unique sleeve bearing product when evaluated against the typical competitive design. The USEM two piece, spherically seated bearing has become an industry benchmark which provides significant advantages over the fixed seated bearing.

General Fabreeka® bushing information:
- Minimum wall thickness of 3/32" is recommended
- Fabreeka® bushing ID is the same as the bolt OD, and the bushing OD is the same as the hole it will fit into.
- To facilitate inserting Fabreeka® bushings, they can be lubricated with a soap solution.
- In general, tolerances on rubber impregnated bushings need not be controlled to the same closeness as required for metal fits, since Fabreeka® is a compressible/flexible material.
- In general production, the tolerance on bushing dimensions is ±1/32". If closer tolerance is required, please contact Fabreeka's® Engineering Department.
Fabreeka® washers are used under the steel washers of the hold-down bolts of Fabreeka® mountings to absorb the rebound shocks and afford complete isolation by eliminating the transmission of vibration through the bolts and steel washers. It also aids in preventing the bolts from becoming loose.

ETP Bushings are the Ideal Locking Device for all Shaft-To-Hub Connections.
ETP Bushings feature a double-walled sleeve, pressure ring and tightening screws. They slide onto a shaft easily, and securely lock most shaft-mounted motion control components in position.
When the bushing screws are tightened the inner and outer walls of the bushing expand, forming a continuous, tight connection on shaft and hub.
