]]>Original equipment manufacturers and industrial distributors worldwide have come to rely on TONGFA quality and support.  Major markets include automotive, consumer product, construction and agriculture, and general industrial goods. Needle roller bearings are roller bearings with cylindrical rollers that are long and thin in relation to their diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited. TONGFA needle roller bearings are available in different designs and a wide range of sizes, which are appropriate for different applications. In addition to customized designs, they comprise the following types: needle roller and cage assemblies drawn cup needle roller bearings and with closed end   full complement, with open ends   needle roller bearings with machined rings   with and without flanges  and without an inner ring   with seals, and without an inner ring   alignment needle roller bearings and without an inner ring   inner rings for needle roller bearings universal joint bearings combined needle roller bearings  needle roller/angular contact ball bearings    needle roller/thrust ball bearings   needle roller/cylindrical roller thrust bearings   needle roller thrust bearings (separate section)   needle roller and cage thrust assemblies    needle roller thrust bearings with a centring spigot

]]>Needle roller bearing Needle roller bearing have a high load carrying capacity insddition to their low cross-section and stiffness . They are especially suitable for bearing arrangements where redial space is limited. Because needle roller bearings only carry pure radial and can not limit the axial diaplacement of shaft relative to the housing . It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearing. Material:Chrome Steel GRC15.HRC58-62 Please feel free to contactus if you are interested.

]]>Needle roller bearings contain many slender rollers with a length 3 to 10 times their diameter. Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity. There are numerous types available, and many have no inner rings. The drawn-cup type has a pressed steel outer ring and the solid type has a machined outer ring. There are also cage-and-roller assemblies without rings. Most bearings have pressed steel cages, but some are without cages.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p> Features Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness.

]]>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. Learn more of the technical details for the following INA bearings and assemblies for machine tool shafts.
