Sealing rings are designed as contact seals. They protect the bearing position against contaminants, spray water and excessive loss of grease.The sealing rings are matched to the small radial dimensions of drawn cup needle roller bearings and needle roller bearings. They are very easy to fit, since they are simply pressed into the housing bore.Sealing rings allow circumferential speeds at the seal lip of up to 10 m/s, dependent on the surface quality of the shaft.

INA slewing rings are known worldwide as premium products in the field of rolling bearing technology. These machine elements have proved themselves many times over, have high load carrying capacity, a versatile range of applications and are highly cost-effective. Due to their design, a single bearing can reliably support radial, axial and tilting moment loads. It is therefore possible in many cases to replace bearing arrangements comprising a combination of radial and axial bearings by a single bearing. This reduces, in some cases considerably, the costs and work required in the design of the adjacent construction and the fitting of bearings.Slewing rings are sealed on both sides, lubricated with a high quality grease, can be relubricated via lubrication nipples and are particularly easy to fit. The bearing rings are supplied without gear teeth or, in order to achieve simple drive solutions, are available with external or internal gear teeth.INA slewing rings are available as four point contact bearings and ascrossed roller bearings.

Drawn cup roller clutches are one-way clutches comprising thin-walled, drawn outer rings with a series of ramps on the inside diameter, plastic cages, springs and needle rollers. They can transmit torques in one direction and are radially compact. The roller clutches are available with and without a bearing assembly.Drawn cup roller clutches give very precise indexing, since individual spring retention of each needle roller ensures constant contact between the shaft, needle rollers and the clamping surfaces. They allow high indexing frequencies due to their low mass and therefore the low moment of inertia of the clamping elements. They also have a low free-wheeling frictional torque.Drawn cup roller clutches can be used in a wide variety of applications, for example as indexing elements, back-stopping clutches or overrunning clutches. The drawn cup roller clutch fulfils the overrunning or holding function as appropriate.

Track rollers are self-retaining, single or double row units with particularly thick-walled outer rings. These bearings can support axial forces in both directions as well as high radial forces. The bearing outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where there is misalignment in relation to the raceway and edge stresses must be avoided. The track rollers are available with an inner ring, with a stud and with a plastic tyre on the outer ring.

INA track rollers LR52 and LR53 now available in X-life quality

INA track rollers series LR52 and LR53 are now available in X-life quality. They can now transmit higher radial loads and have a longer rating life thanks to the optimized internal design.The external dimensions of the new bearings have not changed, which means they can replace earlier bearings without difficulty.

Needle roller and cage assemblies are single or double row units comprising cages and needle rollers.
Since their radial section is no greater than the diameter of the needle rollers, needle roller and cage assemblies allow bearing arrangements with a very small radial design envelope to be achieved. They have very high load carrying capacity, are suitable for high speeds and can be easily fitted.If the raceways are produced to high geometrical accuracy, bearing arrangements with high runout accuracy can be achieved.The radial internal clearance can be influenced by the needle roller sort and by the shaft and housing tolerance.Needle roller and cage assemblies require a hardened and ground raceway on the shaft and in the housing.

Cylindrical roller bearings with snap ring grooves are full complement, self-retaining units comprising solid inner and outer rings, rib-guided cylindrical rollers and sealing rings.The outer rings have grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and are held together by a steel strip that is rolled into place. Cylindrical roller bearings with snap ring grooves are locating bearings. These bearings are highly rigid and can support axial forces in both directions as well as high radial forces.Due to the full complement design of these bearings, they have the largest possible number of rolling elements and thus extremely high basic dynamic and static load ratings. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.

Cost-intensive production plants and supply facilitiesmust offer constant availability. This is made possible by intelligent life cycle service that leaves nothing to chance. FAG Industrial Services (FIS) offers all the maintenance services and products that are needed to achieve this goal. Headquartered in Herzogenrath near Aachen, FIS is an independent company thatmanages all of the Schaeffler Groups industrial service activities for both INA and FAG brands. The range of FIS services covers everything from condition monitoring to mounting work and mounting tools to maintenance management. In cooperation with plant operators FIS develops comprehensive solutions for maintenance, training, quality control, and monitoring tasks. The primary goal is always to provide a high level of machine availability while minimizing maintenance expenses. FIS experts support customers in the mounting and operation ofmachines, install and run condition monitoring systems, repair rolling bearings and conduct analyses and study the causes ofmachine damage and malfunctions for customers all over the world. Early detection of problems and failures in production plants enables users to plan their maintenance activities, carry out repairs when necessary and avoid unscheduled shutdowns. With many years of combined INA and FAG experience and highly qualified experts, FIS is a competent provider of individually tailored solutions in all phases of a project. A global network of competence centers and certified partners guarantees proximity to customers, flexibility and expert service

Housing and bearing units have successfully been used in machinery, installations and equipment. Selection from the wide spectrum of types and sizes manufactured. If other housing types or design variations are required, we should be consulted. Bearing housings are usually made of greycast iron. Housings of cast steel and spheroidal cast iron are available on request. As the bearings are usually lubricated with grease, and the initial grease fill will last for a long time, most housings can do without lubricating holes. They featurecast-on flat bosses or markings allowing lubricating holes to be drilled if needed. In the case of relubrication, escape of the surplus grease must be ensured.As a rule, the bearing seats in the housings are machined in such a way that the bearings can be displaced, i.e. they are of the floating type. Locating bearing mountings are obtained by inserting the locating rings listed in the tables. Locating rings have to be indicated separately in the order. Housings without locating rings are supplied either as floating bearing housings or as locating bearing housings. All outer surfaces which are not machined are provided with a universal coat of paint. The coat of paint can be finished with all synthetic resin, polyurethane, acrylic, epoxy resin, chorine rubber, cellulose and acid-hardening hammer dimple enamels. Depending on the operating conditions, the bearing housings can be sealed with rubbing seals, non-rubbing seals, and combinations of both, see illustrations below
