Industrial - Supplementary Product Information

Deep Groove Ball Bearings Available as Single or Double Row type. Features include open, one or two shields, one or two seals and locating snap ring. Also available as Extra small, Miniature and Maximum types. The most popular type of bearing, it supports both radial load and a certain degree of axial load in both directions simultaneously.

• The most popular types among rolling bearings, widely used in a variety of industries.
• Radial load and axial load in both directions can be accommodated.
• Suitable for operation at high speed, with low noise and low vibration.
• Sealed bearings employing steel shields or rubber seals are filled with the appropriate volume of grease when manufactured.

Cylindrical Roller Bearings Available as Single, Double or Four Row. Features include Thrust Collars, parallel or tapered bore and lubrication holes and grooves. These feature high radial load capacity as the rollers and raceway are in linear contact. Suitable for heavy radial and impact loading.

• Since the design allowing linear contact of cylindrical rollers with the raceway provides strong resistance to radial load, this type is suitable for use under heavy radial load and impact load, as well as at high speed.
• N and NU types are ideal for use on the free side: they are movable in the shaft direction in response to changes in bearing position relative to the shaft or housing, which are caused by heat expansion of the shaft or improper mounting.
• NJ and NF types can accommodate axial load in one direction: and NH and NUP types can accommodate partial axial load in both directions 
• With separable inner and outer ring, this type ensures easy mounting.
• Due to their high rigidity, NNU and NN types are widely used in machine tool spindles.

Tapered Roller Bearings Available as Single or Double row, and in Metric and Inch sizes. Can be produced as either TDO (one double cup and two single row cones) and TDI (one double cone and two single row cups) Designed so that cups, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. This type is suitable for applications involving heavy or impact loading.

• Single-row bearings can accommodate radial load and axial load in one direction, and double-row bearings can accommodate radial load and axial load in both directions.
• This type of bearing is suitable for use under heavy load or impact load.
• Bearings are classified into standard, intermediate and steep types, in accordance with their contact angle.
• The larger the contact angle is, the greater the bearing resistance to axial load.
   

Items sized in inches are still widely used.

Spherical Roller Bearings This type features a large load rating capacity and self-aligning capability. Cylindrical and Tapered bore are available, as are Adapter assemblies and Withdrawal sleeves. Suitable for low or medium speed applications which involve heavy or impact loading.

• Spherical roller bearings comprising barrel-shaped convex rollers, double-row inner ring and outer ring are classified into four types: R, RH, RHR and RHA, according to their internal structure.
• With the bearing designed such that the circular arc center of the outer ring raceway matches with the bearing center, the bearing is self-aligning, insensitive to errors of alignment of the shaft relative to the housing, and to shaft bending.
• This type can accommodate radial load and axial load in both directions, which makes it especially suitable for applications in which heavy load or impact load is applied.
• The tapered bore type can be easily mounted/dismounted by using an adapter or withdrawal sleeve.

Needle Roller Bearings Designed to be small in sectional height for products with space constraints. Available as Drawn Cup, Machined Ring, Thrust, Stud type (Cam followers), Yoke type (roller followers) and as Miniature One way Clutches. Compact, highly rigid and superior in load carrying performance. Excellent for carrying oscillating loads. Now greatly used as miniature clutches in office equipment.

• In spite of their basic structure, which is the same as that of NU type cylindrical roller bearings, bearings with minimum ring sections offer space savings and greater resistance to radial load, by using needle rollers.
• Bearings with no inner rings function using heat-treated and ground shafts as their raceway surface.

Angular Contact Ball Bearings Available as Single or Double row, Matched Pair and Four Point Contact. Designed for high accuracy good high-speed performance. Carries a combined load, axial and radial.

• Bearing rings and balls possess their own contact angle that is normally 15, 30 or 40.
  Larger contact angle --- higher resistance against axial load
  Smaller contact angle --- more advantageous for high-speed rotation
• Single-row bearings can accommodate radial load and axial load in one direction.
• DB and DF matched pair bearings and double-row bearings can accommodate radial load and axial load in both directions.
• DT matched pair bearings are used for applications where axial load in one direction is too large for one bearing to accept.
• Angular contact ball bearings are used for high accuracy and high-speed operation.
