IKO LBalls are selfaligning Spherical Bushings consisting of a special zinc diecast alloy body and a studded ball which has its axis at right angles to the body. They can perform tilting movement, oscillating movement and rotation with low torque, and transmit power smoothly due to uniform clearance between the sliding surfaces. Their superior wear resistance assures stable accuracy for long periods of time, and maintenance is simple. They are very economical bearings. For these reasons, they are widely used in link mechanisms in automobiles, construction machinery, farm and packaging machines, etc.

These bearings are doublerow, full complement with a low cross sectional height designed for use in sheaves. There are two types, sealed and shield type. They can withstand heavy radial loads and shock loads at comparatively lowspeed rotations, and can also withstand axial loads. It is easy to fix them axially to sheaves using the stop rings of the outer ring. The width of the inner ring is designed to be larger than that of the outer ring, so they require no spacer between sheaves. The structure is stable because the doublerow of rollers can withstand the moment loads caused by rope transition. The surfaces of these bearings are also treated to provide high corrosion resistance.

IKO Roller Bearings are heavy duty bearings with rollers incorporated in a double row. They are nonseparable bearings with a high load rating. They can withstand not only radial loads but axial loads as well, which are supported at the contacts between the shoulders of the inner and outer rings and the end faces of the rollers. They should be used at the fixing side of a shaft. Like needle roller bearings, they are also compact. Roller bearing types include caged, full complement and the type for sheaves, and they can be selected based on the operating conditions. These bearings are used in heavyduty machinery such as construction equipment, and industrial machines.

Franke FDH linear guides are suitable for linear movement tasks, especially in dynamic pick-&-place applications. They have rollers with angular contact ball bearings for the highest acceleration and speed values, for example when using linear motors as the drive source. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly.

A roller with a solid shaft as standard, hollow shaft as option Bearing seats formed as an integral part of the shell, the opposing bearings are therefore accurately aligned The formed bearing holders improve bearing performance leading to lower failure rates Dimensions: Roller diameters 152 – 219 mm (6” to 8-5/8”) Shaft diameters up to 62 mm (2-1/2”) Bearings 6306, 6308, 6310, 6312

Franke FDB linear guides are suitable for linear motion tasks in almost all industries. They are particularly convincing in cost-sensitive applications with reduced demands on load and noise. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly.

Housing washer, shaft washer and rolling elements, bearing steel. Cage, steel. Note Axial ball bearings accept high axial loads from one direction but may not be loaded radially. The bearings are separable. This means the bearing parts can be fitted independently of each other. The main dimensions of the axial ball bearing conform to ISO 104 and DIN 711. Dimensional and running tolerances correspond to tolerance class PN acc. to DIN 620. These tolerance classes are standard and are well suited for most applications.

Steel housing. Nitrile rubber seal. Preloaded highaccuracy bearings with a 60° thrust angle. The bearings accept both radial and axial forces from both directions. Due to their preload, the angular contact ball bearings provide a high level of stiffness, excellent concentricity, precise tool positioning and repeatability. The integrated lowfriction seal effectively keeps dirt away from the bearing, thereby ensuring excellent operating safety and a long service life. The bearing friction coefficient Mrl is a reference value. The moment of inertia corresponds to that of the rotating inner ring. The limiting speeds are applicable after grease is applied. Technical data All bearings are supplied ready for mounting with lubricating grease type KE2P35 acc. to DIN 51825. Housing and shaft tolerances correspond to roundness tolerance class IT2 and perpendicularity tolerance class IT4.

Ceramic bearings Si3N4. Bearing cage PTFE. For most applications Si3N4 is the preferred material for ceramic bearings. Silicon nitride bearings are light, very hard and highly wear resistant. High and ultrahigh performance bearings are used in e.g. aerospace technology, metal production industries (high application temperatures), machine manufacturing, chemical industries (chemically aggresive substances), pharmaceutical and medical industries, semiconductor and biotechnology (clean room enviroments which may not be contaminated by lubricants). On request Special version with PEEK ball cage. Without ball cage.

Inner ring, outer ring and rolling elements, bearing steel. Cage sheet steel. Labyrinth seal sheet steel. Lip seal NBR. Version 2Z = sealed both sides with noncontact labyrinth seals. 2RSR = sealed both sides with contact lip seals. Note Deep groove ball bearings accept high radial and axial loads. Axial loads are absorbed in both directions. The versions 2Z and 2RSR are lubricated for life with a high quality grease. The main dimensions of the deep groove ball bearings conform to DIN 6251. Dimensional and running tolerances correspond to tolerance class PN acc. to DIN 620. The radial internal clearance corresponds to the clearance CN acc. to DIN 6204. These tolerance classes are standard and well suited for most applications.

Housing steel. Cage plastic. Balls steel. Note The linear ball bearings correspond to series 3 of ISO 10285. With doublesided seal. The linear ball bearings have a plastic cage which results in quiet and outstanding running properties. With flange for direct mounting on the housing. Linear ball bearings with doublesided seal should be greased before installation. The specified load ratings apply with the use of hardened and ground shafts. Precision guide shafts 21595. Fastening screws 07160.

Steel rollers with jacket consisting of tube and bearing mounting head rigidly coupled by pressure. They are mounted on pre-lubricated angular or radial ball bearings protected with double-labyrinth dust seals. Clamped steel rollers are used in belt conveyors with limited or medium-heavy loads. The diagrams and tables on page 34 show the dimensional characteristics and maximum loads. Operating temperature:-10 ÷ +90 [°C].
