Cylindrical roller bearings feature high radial load capacity because the rollers and raceway are in linear contact. These bearings are suitable for applications that involve heavy radial and impact loading. They are also appropriate for high- Speed applications in that they can be machined very accurately due to their structure. Having a separable inner ring or outer ring, These bearings can be mounted and dismounted easily. Single- Row cylindrical roller bearings. The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft's axial movement, To a certain extent, Relative to the housing position. The NJ and NF types carry axial load in one direction, While the NUP and NH types can carry a certain degree of axial load in both directions. Type R cylindrical roller bearings feature enhanced load rating compared with standard series, Though both have equal dimensions. This is because type R bearings have different interior design. They are identified by supplementary code "R". Double- Row cylindrical roller bearings. Double- Row cylindrical roller bearings come in two types : With a cylindrical bore, And with a tapered bore. As for those with a tapered bore, The specified amount of clearance can be obtained by adjusting the press- In distance. Some bearings have lubrication holes and lubrication grooves on the outer ring. They are identified by supplementary code "W". These bearings can accommodate high radial loads, And are often used on machine tool spindles.

he company especially expertises in the angular-contacted clutch bearing, self-aligning clutch release bearing and pull-type clutch bearing and sets, also have several hundreds of bearing products in several series.
It is wall wrapped bearing made of triple layer composites material which consists of a steel backing, a sintered porous bronze particles interlayer and calendared with PTFE and Pb mixture as surface layer, It is of low friction cofeeicient, anti-wear, anti-corrosion and can be used without oil, or only a trace of oil os needed. moreover, it is of low cost, low vibration and low noise, compact and light, sf-1Xis widely applied in various sliding articles of different kind of machines, Such as textile machines, tobacoo machines, hydraulic vechicles, antomobiles, agriculture and forests machinese and soon.
In spherical roller thrust bearings the load is transmitted from one raceway to the other at an angle to the bearing axis. The bearings are therefore suitable for the accommodation of radial loads in addition to simultaneously acting axial loads. Another important characteristic of spherical roller thrust bearings is their self- Aligning capability. This makes the bearings insensitive to shaft deflection and misalignment of the shaft relative to the housing. Spherical roller thrust bearings incorporate a large number of asymmetrical rollers and have specially designed raceways with an optimum conformity. They can therefore support very heavy axial loads and permit relatively high speed operation. When low- Carbon, Carburized grades of steel are used, Carbon is introduced after the spherical roller bearings are machined to a depth sufficient to produce a hardened case that can sustain bearing loads. The addition of carbon and alloys ensures the proper combination of a hard, Fatigue- Resistant case and a tough, Ductile core. Spherical roller thrust bearings are produced in two designs depending on the size and series. Bearings up to and including size 68 identified by the designation suffix E have a pressed steel window- Type cage, Which, With the rollers, Forms a non- Separable assembly with the shaft washer. All other bearings have a machined brass or steel cage which is guided by a sleeve held in the shaft washer bore. The shaft washer and cage with rollers form a non- Separable unit.
The INA bearing group currently employs approximately 28, 000 people worldwide. Almost 7, 000 of these work at company headquarters in northern Bavaria. With nearly 40 manufacturing plants and a sales network extending across every continent, INA ensures that all customers receive expert advice and prompt deliveries from a location appropriate to their area. The INA product range inludes needle roller bearings, linear solutions, actuation systems and engine components. INA rotary table bearings, series YRT + RTC, are ready-to-mount units with adjusted preload for the highest possible accuracy, rigidity and load carrying capacity for oscillating axes. In addition to the conventional bearing solutions, you will find the angular contact thrust ball bearing ZKLDF in INA s product range. This bearing has an especially low friction torque and very high speeds.A new product in INA s range is the all-round rotary table bearing, series YRT speed. The full range of INA bearing products are on stock for call of to your schedules. Special bearing designs can also be catered for through our engineering departments. This bearing is predestined for use with direct drives. Besides its excellent dynamic characteristics, it has increased rigidity and load carrying capacity.
