NACHI NJ207 NJ200 Cylindrical Roller Bearing, 35 mm Dia Bore, 72 mm OD, 1 Row, 17 mm W, 33500 N Dynamic/31500 N Static Load
Cylindrical Roller Bearing – ‘NJ’ CONFIGURATION Cylindrical Roller Bearings utilize a modified cylindrical roller that provides line contact with the inner and outer ring raceways. They are suitable for high speeds and have a high radial load capacity. The rollers are guided by ribs on either the inner or outer rings. Depending upon the configuration, the bearings may or may not be able to accept any axial loading. The inner and outer rings are separable which may aid in assembly/disassembly of components. The ‘NJ’ Type bearings has shoulders on both sides of the outer ring and one shoulder on the inner ring. This allows the bearing to accept light axial loads in one direction. Some sizes may be available in a high capacity design (EG) that has larger diameter rollers and a polyamine cage. Stamped steel or machined brass (MY) cages are generally used. These bearings are most commonly used in gearboxes, rolling mills, crushers and pulverizers.
NACHI H-L44643R/10 Tapered Roller Bearing, 25.4 mm Dia Bore, 50.292 mm OD, 1 Row, 14.224 mm W, 31200 N Dynamic/37000 N Static Load
A tapered roller bearing consists of a cone (or inner ring), the cup (or outer ring), tapered rollers and a cage. The tapered rollers allows the bearing to handle a combination of heavy radial and thrust loads. The bearings are separable. Internal clearance is established during mounting by the axial positioning of the cone relative to the cup. Preloading this bearing can obtain a higher rigidity and better running accuracy to optimize performance. They are used mostly for heavy duty, moderate speed applications. These bearings are generally used in pairs and are most common on agriculture, construction and mining equipment, vehicle and trailer axles and in gear boxes.
NACHI 7314B Angular Contact Ball Bearing, 70 mm Dia Bore, 150 mm OD, 1 Row, 35 mm W, 40 deg, 118000 N Dynamic/88500 N Static Load
The single-row angular contact ball bearing was designed to support radial, axial or composite loads, however, the axial load must be in one direction. The high thrust capacity is achieved by a higher shoulder on one side of the outer ring. The direction of the load through the balls forms the contact angle. The thrust capacity increases with the contact angle. The BMU bearings are commonly referred to as thrust bearings. These bearings have a 40 deg contact angle to accept heavy axial loads. The bearings have Universally Flush Ground rings to facilitate mounting in multiple bearing sets. The inner and outer rings have identical widths. These bearings can be mounted as DB, DF and DT pairs or can be combined into triplex and quadraplex sets. When two bearings are mounted together, a clearance or preload may be obtained without the use of shims or spacers. This bearing has a machined brass cage and is not available with seals or shields. These bearings are most commonly used in vertical pump and motor applications.
NACHI 7212B Angular Contact Ball Bearing, 60 mm Dia Bore, 110 mm OD, 1 Row, 22 mm W, 40 deg, 58000 N Dynamic/46000 N Static Load
The single-row angular contact ball bearing was designed to support radial, axial or composite loads, however, the axial load must be in one direction. The high thrust capacity is achieved by a higher shoulder on one side of the outer ring. A matching high shoulder is often on the opposite side of the inner ring as well. The direction of the load through the balls forms the contact angle. The thrust capacity increases with the contact angle. This ball bearing has a 40 deg contact angle. This bearing has a stamped steel cage and is not available with seals or shields. These bearings are non-separable. These bearings have normal tolerances and are not suitable for mounting adjacent to each other to achieve a preload.
NACHI 6301ZZENR 6300 Deep Groove Ball Bearing, 12 mm Dia Bore, 37 mm OD, 1 Rows, 12 mm W, 9750 N Dynamic/4250 N Static Load
Single-row deep groove ball bearings are the most common bearing type in the world due to their versatility and performance. These bearings are available in a variety of seal, shield and snap-ring arrangements. Bearings with seals or shields are standardized and already contain the proper amount of grease. Open bearings will require lubrication. These bearings can sustain radial and/or axial loads and because of their simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation.

NACHI 6200ZZENR Deep Groove Radial Ball Bearing, 10 mm Dia Bore, 30 mm OD, 1 Row, 9 mm W, 5100 N Dynamic/2390 N Static Load
Because of their versatility, Single-row, Deep-groove Ball Bearings are the most popular of all the ball bearing types. NACHI Deep-groove Ball Bearings are available in a wide range of series defined by the JIS (ISO) standard dimension plan and are also made to meet specialized dimension and configuration requirements.

NACHI 6004 2NSE Deep Groove Ball Bearing, 20 mm Dia Bore, 42 mm OD, 12 mm W, 9400 N Dynamic/5000 N Static Load
NACHI 5304ZZ 5300 Angular Contact Ball Bearing, 20 mm Dia Bore, 52 mm OD, 2 Rows, 22.2 mm W, 20 deg, 21700 N Dynamic/13300 N Static Load
A double-row angular contact ball bearing is basically two single-row angular contact ball bearings with 20 deg contact angles, mounted back-to-back while contained within a narrower single bearing. These bearings occupy less axial space and can take a bi-directional axial, radial and moment loads in one bearing where it takes a matched pair otherwise.
NACHI 21309EXQW33C3 Spherical Roller Bearing With Cylindrical Bore, 45 mm Dia Bore, 100 mm OD, 2 Rows, 25 mm W, 150000 N Dynamic/124000 N Static Load
Double-rowed spherical roller bearings are the workhorse of the industry. Their barrel shaped rollers and spherical outer ring raceway permits this bearing to operate with misalignment with no reduction in bearing life. Spherical roller bearings are used mostly in heavy duty industrial applications where extreme radial loads exist. They also excel in handling axial loads in either direction, contaminated environments, misalignment, shock loads and vibration. Nachi Sphericals are manufactured in a number of design and material configurations depending upon the type of application and the size of the bearing. Most come standard with a lubrication groove and holes (W33) on the OD of the outer ring. Symmetrical or Asymmetrical (A) rollers may be used with stamped steel or machined brass cages. The "EX" design uses larger diameter rollers for the highest load ratings. All bearings are heat stabilized to at least 200 deg C (about 400 deg F). Some sizes may be available with tapered bores (K). Depending upon design, stamped steel or machined brass cages are used. Commonly used in gearboxes, wind turbines, pumps, mining/construction, marine propulsion and drilling equipment.
