Needle bearing / roller / combined
For united needle and roller bearings for screw drives, they are accorded to reach very high cutting speeds while making sure the accuracy level requested for each function are met. Unitec SRB combined bearings makes use of static and dynamic stiffness for ballscrews.
The SRB bearings are needle roller bearings that has an outside ring with raceways for two axial cages and a broad inner ring, where the axial cages are in the middle.
The bearings can also provide a high degree of accuracy and stiffness, along with a development for the radial/axial support for accurate ball screws of machine tools. For the maximum stiffness to be reached, the bearings are preloaded by using a locknut.

Needle cage - ID : 3 - 110 mm, OD : 5 - 117 mm
Schaeffler needle roller and cage assemblies are single or double row units that include cages and needle rollers.
The radial section of the assemblies is smaller than the diameter of the needle rollers. This enables the needle roller and cage assemblies to achieve bearing settings with small radial design envelope.
The devices are ideal for high speeds and have a capacity of carrying high loads. They are easy to fit. It is possible to get bearing arrangements with high accuracy of runout by producing raceways to greater geometrical accuracy.
The needle roller sort and tolerance of the shaft and housing can affect the radial internal clearance. Both shaft and housing of the needle roller and cage assemblies demand a hardened and ground raceway.

Drawn cup needle roller bearing - ID : 3 - 210 mm, OD : 6.5 - 240 mm
Drawn cup needle roller bearings with a closed end open ends are components containing thin-walled drawn external rings and needle roller and lock in assemblies. Drawn cup need roller bearings with open ends come with complete complement variants. Most of the bearings are single row designs. Drawn cup needle roller bearings with closed ends and open ends are obtainable in open and closed variants. Owing to the thin-walled external drawn cup and the lack of an internal ring, drawn cup needle roller bearings with a closed end and open ends have a very low radial section height. They contain extremely high load carrying ability, are appropriate for high velocities and can be effortlessly fixed. If snap rings, shoulders, etc., are not used for axial location, the housing bore can be shaped effortlessly and in particular economical.

Needle bearing / self-aligning - ø 12 - 45 mm
Aligning needle roller bearings are composed of drawn outer cups, outer rings with a spherical-shaped outside surface, plastic support rings with a concave-shaped inner profile, needle roller and cage assemblies, and inner rings that are removable.
Static shaft misalignments are compensated so that shaft misalignment relative to the housing is tolerated. These bearings feature firm seating in the housing bore so that bore production is simple and economical.
Aligning needle roller bearings are considered as X-life bearings, in which the geometrical accuracy and roughness of the raceways have been optimized. This provides increased load carrying capacity and longer operating life.

Drawn cup needle roller bearing - OD : 3 - 60 mm
TIMKEN's Drawn Cup Needle Roller Bearings is designed and created to support radial loads and the reduction of friction between rotating components. Its low cross section supplies a high load-carrying capacity with minimal space required. The drawn cup bearings can simply be installed with a press fit in its housing. The full complement and the caged version are two of Drawn Cup Needle Roller Bearings' basic designs which has drawn outer shell which serves as a raceway for the rollers contained in its bearing. Its full version has the highest number of rollers mechanically kept through the aid of a drawn outer shell. The design incorporates high radial load-carrying capacity in a less-expensive manner. Its standard version has a single piece steel cage to guide and maintain the rollers.

Drawn cup needle roller bearing - OD : 4 - 30 mm (1/8 - 1")
Drawn cup - roller clutches form tools that can help in transmitting torque between housing and shaft in a particular direction. They also provide free overrun in opposite direction. They make use of smaller radial - section similar to that of drawn cup - needle roller - bearings. They can be used for operating directly over the hardened shaft and are light weighted and compact. There is a simple - press fit in housing which enables them to be installed easily. They are available either in the units of clutches or as assemblies of bearings and clutches. Both these forms can have metric and inch nominal series. They can be used with bores of size ranging from 4 to 30 mm. At the time of torque transmission either housing or shaft can act as input member. Rollers usually wedge against the interior ramps for positive transmission of torque. Transition to lock from overrun can happen with minimal loss of motion.

Needle bearing / heavy-duty - OD : 5 - 100 mm (0.625 - 9.25")
Heavy-duty needle roller bearings are composed of a machined and ground channel-shaped outer ring with a complement of needle rollers retained and guided by a cage. The thick outer ring ensures maximum load capacity and shock resistance with a relatively small radial cross section. The device is designed with high-strength cage retaining and guiding the rollers to ensure superior speed and lubrication retention. A lubrication groove and hole in the O.D. is used for relubrication through the outer ring.
Depending on the suitability of the shaft as a raceway surface, the bearing are used with or without a machined and ground inner ring. The bore size ranges from 5 mm - 100 mm (0.625 in. - 9.25 in.). The bearings feature high-strength cage that enables to retain and guide rollers. The bearings feature high speed and lubrication-retention capability. The bearings can be used with or without a machined and ground inner ring based on the suitability of the shaft as a raceway surface.
