Thrust roller bearing
Needle in the proximal surface of the surface profile is slightly contracted. Line contact needle roller and the results can be revised to avoid damaging the edge of the stress. Bearing needle roller bearing outer ring line thick, high temperature nitrogen quenching, high-precision separation of the roller by the high rigidity outer wall to guide the use of linear contact wheel can easily turn in a raceway, and can under heavy load. For the removal of stress, support the use of arc outer wheel design, a wheel with a single curve, double ring, with no seals, seal rings and other kinds of models. Grease a large space with a storage ring to provide long-term lithium grease lubrication, and extended lubrication intervals. Ring with a skeleton made of nitrile rubber or ST12, the operating temperature range of -30 ° C to +100 ° C or -30 ° C to +180 ° C. Density curve wheel-mounted to withstand extremely heavy loads and high-performance operation. RSTO no outer wall, roller bearing without inner ring
Needle bearing characteristics and uses:
With thin and long needle bearing roller (roller length diameter of 3 to 10 times the diameter of generally not more than 5mm), so the radial structure is compact, its diameter size and load bearing capacity and other types of the same, minimum diameter, especially for radial bearing installation dimensions restricted results. Depending on different occasions, can be used without inner ring of the bearing or needle roller and cage assemblies, this time with the match of the journal bearing surface and directly on the surface as the bearing housing bore of the inner and outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing, shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar to the roller bearing rings. Such bearings can only bear the radial load.
Needle bearing type
In addition to catalogs listed, the bearings can be used for general engineering, such as: open-type Needle roller bearings (1), closed-end Needle roller bearings (2), needle bearing inner ring (3) and non- needle bearing inner ring / no cage needle roller bearings without inner ring (4), a cage and needle roller bearings without cage filled with (5) SKF can supply all types of needle roller bearings, 1 needle cage assembly 2, needle roller bearings without ribs 3, self-aligning roller bearings 4, combined needle roller / ball bearings 5, combined needle roller / thrust ball bearings 6, combined needle roller / cylindrical roller thrust bearings outside STO ring without ribs, with the wheel bearing inner ring RNA22 ... 2RS sealed on both sides, not inner roller bearing NA22 ... 2RS sealed on both sides, with an inner ring bearing roller NATR NATR ...

Needle roller bearings
Needle roller bearings with a thin metal forming the outer ring of needle roller bearings. Its main characteristic is low sectional height and bear higher load capacity. Mainly used in compact, inexpensive and bearing inside the hole as the needle roller and cage assembly can not roller bearing configuration. Bearings and bearing housings shall be to interfere with the way the installation. Shoulder can be avoided if the box, such as axial stop ring positioning, then the bearing inside the hole can be done very simple and economic.
Mounted on the shaft of the drawn cup needle roller bearings with open sides (1) and unilateral closed (2). Drawn cup closed end of the base can not withstand the axial guiding force.
Needle roller bearings are generally not attached to the inner ring. In the journal can not be hardened and ground of the occasion, you can use inner ring listed in the table.
Needle roller bearings of hardened steel outer ring and needle roller cage assemblies can not be separated. Free lubricant storage space can be extended to add lubrication interval. Generally use the single bearing design. However, bearing wide specifications except for 1522,1622,2030,2538 and 3038 series, which is equipped with two needle roller cage assemblies. Bearing outer ring with lubrication holes. According to user needs, shaft diameter greater than or equal to all the single 7mm Needle roller bearings can be equipped with lubrication holes in the outer ring (code suffix AS1).
Needle roller bearings with seals
Can not be installed due to space constraints in the seal of the occasion, to provide open-ended or closed end Needle roller bearings with seals (3-5). Such bearing equipment polyurethane or synthetic rubber friction seal, which filled with good anti-rust properties of lithium-based grease for operating temperature -20 to +100 ℃.
A seal bearing inner ring outer ring width than 1mm, which makes bearings in the shaft to the bearing box with a little shift can also work to ensure a good seal and prevent injury to the bearing contamination. Bearing inner ring has lubrication holes can be configured according to the needs of the bearing from the outer or inner ring to add lubrication.

Physical ring needle roller bearings
Entity by a needle bearing ring or two rings and the cage with the needle group composition. According to the different applications can be divided into an inner ring or inner ring bearings. Therefore, to meet the physical ring needle roller bearings, light weight, small footprint, large transmission power requirements. Physical ring needle roller bearings with a smaller size and higher carrying capacity.
Main Structure Type
Outer double-wall (or double-lock loop) with cage needle roller bearings NA, NKI-type inner and outer rings can be installed separately (with lock ring, a full set of needle roller and cage), access high speed, single and double points column two. If the shaft can not be used as a raceway, hardened shaft that If we can not use abrasive or economy, you can use these needle roller bearings with inner ring.
There is no inner needle bearing cage
NA, NKI-type bearings without inner ring is RNA, NK-type needle roller bearings. Such bearings without inner ring, radial mounting dimensions for the supporting structure restricted, and the match of the journal bearing as the rolling surface directly. As a raceway shaft, and grinding the hardware must be quenched, and only be processed to the appropriate size and shape accuracy, the entire needle bearing life and operation to a higher accuracy. Also, because no inner ring, the diameter of the shaft may also be appropriate to increase, thus increasing the rigidity. [1]
Combined needle roller bearings
Combined needle roller bearings are roller bearings and thrust to the heart of a combination of the bearing unit bearing components, and its compact structure, small size, high precision rotation, can withstand high radial load at the same time bear a certain axial load. And product structure forms, wide adaptability, easy to install. Combined needle roller bearings are widely used in machine tools, metallurgical machinery, textile machinery and printing machinery and other machinery and equipment, and allow the mechanical system is very compact and smart design.
Thrust needle roller bearings
With a needle or by a thrust bearing cylindrical roller or ball thrust cage assembly and the thrust washer composition. Needle roller and cylindrical roller cage maintained by the thrust and guidance. DF with different series of thrust bearing washer when used together, can be configured to provide bearing many different combinations. As the use of high-precision cylindrical roller (needle) to increase the contact length, making this a very small space in the lower bearing for high load capacity and high stiffness. Another advantage is that if the adjacent parts of the surface suitable for raceway washer can save, make the design compact, DF thrust needle roller bearings and cylindrical roller bearing thrust needle roller and cylindrical roller cylindrical surface is surface modification can reduce the edge stress, improve life.
