Plastic Pulley Bearing Nylon Bearing

Elastomeric bearings reinforced internally with one or more steel plates, chemically bonded during vulcanisation are called laminatid elastomeric bearings. Elastomeric bearings permit a smooth and uniform transfer of loads from beams to substructure and also allow beam rotations at the point of support due to deflection of beam under loading. They further allow lateral and longitudinal movement of beams caused by thermal forces. Elastomeric bearings have no moving parts and thermal expansion and contractions are supported by shear capacity of elastomers. There is no sliding motion between bearing and beam or between bearing and abutment.

MODEL RG - FREE ROLLER-COATED DIAMETER 32 MM - PITCH 40 MM FOR SMALL AND FRAGILE PACKAGES Free rollers conveyors that consist of sturdy painted steel 2 mm thick, 50x25 mm tubular support, legs fixable on floor and adjustable in height, 32 mm diameter steel rollers coated with rubber, rotating on ball bearings (8mm axle). The versions with a width of 1000 mm consist of a 2-roller axis with central support. This solution allows to have a greater flow rate that reaches up to 90 Kg/m.

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.

Housing, grey cast iron. Bearing, ballbearing steel 100Cr6. Seal, rubber NBR. Pillow block bearings consist of a sealed singlerow ball bearing with a spherical outer ring which is mounted in a housing. Because of the spherical outer surface of the bearing, shaft misalignment can be compensated for. The bearings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with htolerances. The shaft is secured by grub screws on the inner ring. In normal applications, pillow block bearings are maintenancefree due to the lifetime lubrication. In difficult environmental conditions relubrication can be carried out over the grease nipple. All housing dimensions are nominal dimensions for which the usual casting tolerances must be taken into consideration.

The reinforced universal adapter with brass bushings is intended for converting a hand auger into a power auger, using a cordless screwdriver or a motor during the ice drilling. With a drill screwdriver and the universal adapter, ice is drilled easily, allowing spending a minimum effort and time on drilling. The brass bushings play the role of plain bearings. Compared to rolling bearings, they have a longer service life, are more wearresistant and also have increased anticorrosion properties. They withstand all the frictional forces and protect the adapter from wear, extending the product life under high loads. They also protect the adapter from moisture. The improved twostage design of the adapter output shaft has 19 mm and 22 mm diameters. Suitable for TORNADO, BURAN ice augers with the bit directly or with an extension; MOTOSHTORM bits with a bit directly or with an extension; ICEBERG ice augers with the bit directly or with an extension * The extensions are sold separately

Elastomeric bearings we have defined so far are the basic types, which constant feature is the fact that they allow all-ways movements and rotation. However, movements can be limited in one or all ways, thus obtaining guided or fixed bearings, respectively. In the first case -guided bearings- the restriction is obtained by means of guides parallel to the supporting axe that allows movement. To make friction as low as possible, PTFE and stainless steel sheets are welded to the guides.

If, on the contrary, a fixed bearing is desired, guides are added parallel to both axes, so that movement is completely blocked. Each elemental layer, subject to stresses and movements, deflects

These isolators are similar to the previous but with the exception that the dissipation of energy is obtained also through the use of one or more lead cores. Lead (used here at a level of gg.go% purity) has the property of undergoing plastic deformation as it dissipate energy and then re-crystallizing after a cycle of plastic deformation. Because of this, it is able to sustain an unlimited number of hysteresis loops.

The behavior of the LDRB isolators is highly linear in shear stiffness and the damping ratio is 2 - 3% of critical damping. There is no creep in the material and the stability of the modulus of elasticity is very good. Advantages of LRDB insulators; they can be modulated in a simpleway and they are less affected by the factors that have mechanical behaviors. These insulators may need additional damping elements.

High damping rubber bearing (HDRB) were developed in 1985 by Professor James Kelly at the University of California at Berkeley. Ozdekan was the first company which manufactured and applied this technology in Turkey, using it in 2014 for the AFAD building in Ankara, Turkey. The isolating system was designed with consultation by engineers. Ozdekan was the first company in Turkey which developed the lead rubber bearings with consultation of university researchers. The HDRB isolators are composed of a series of vulcanized rubber layers separated by reinforcing steel plates, thus providing a device capable of supporting high vertical loads with minimal compression (elevated vertical stiffness) and allowing high horizontal displacements with relatively small reactions (low horizontal stiffness). www.ozdekan.com
