A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads.

The term angular contact ball bearings is a term used for special ball bearings. Analogue to radial deep groove ball bearings, the balls are guided through deep grooves in the inner and outer race with a narrow bevelling plane.

Spherical roller bearings consist of an outer ring having a continuous spherical raceway centred within and two rows of barrel-shaped rollers operating in separate raceway ground into the inner ring with a centre rib to guide the roller. This type of bearing has a self-aligning nature, so it can be used in cases where misalignment between the inner and outer ring occur from shaft mounting errors of shaft deflections.

The allowable misalignment for these bearings, being varied due to the dimensional series and loading conditions, is about 0.0009 radian (0.5’) for ordinary loads. For light loads, this angle can be up to 0.035 radians (2’).

These bearings have a large capacity for radial loads, axial loads in either direction, and combination

Of these loads. They are also suited for applications where vibration or impact forces are encountered.

The design of spherical roller bearings are standardized so that the centre roller guide rib comes standard with the inner ring as one united inner ring.

Four row tapered roller bearings can accommodate combined (radial & axial) loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills.

BEARING FEATURES

Depending on their design, four-row tapered roller bearings provide the following main features and benefits:

Long service life

The four-cup design (four separate outer rings) provides optimal load distribution over all four rows of rollers.

Enhanced Operational Reliability

Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

SPHERICAL ROLLERBEARINGSWith a bearing that needs to withstandhigh temperature, contamination, increasedspeed, and overloading, a long operatinglife becomes challenging. However, with thesuitable material, innovative technology, anddesign, NBC has added some beneficialfeatures to Spherical Roller Bearing that willbe performance enhancers.

Double Row Spherical Roller Bearings
Spherical Bearings, Industrial Bearings.

Double row spherical roller bearings are of non-separable construction. They are manufactured in multiple series.

Double-row spherical-roller bearings are manufactured either with cylindrical or tapered bore, the taper ratio of which is normally 1:12. However, for series 240 and 241, the taper is 1:30. The bearings having a cylindrical bore are fitted straight onto a cylindrical shaft, whereas a bearing having tapered bore is to be mounted either on a shaft having same taper as in the bore of the bearing, or on a straight shaft by means of an adapter sleeve or a withdrawal sleeve, inserted between the shaft and the bearing. Double row spherical roller bearings have two rows of spherical rollers with a common spherical track on the outer ring bore. This allows swivelling of the bearing inner ring with respect to the outer ring around the centre of the bearing, without affecting its correct function. Thus, these bearings are capable of compensating misalignment, shaft deflection and even machining error in the machine components to a certain extent.

These bearings can transmit high radial and axial loads in either direction simultaneously.

Double row spherical roller bearings have high load carrying ability. The bearings are supplied with standard radial clearance. However, bearings for special applications can be supplied either with lower or higher radial clearance. The bearings are manufactured in normal accuracy class, However, bearings with higher running accuracy can also be supplied.

hrust Ball Bearings

• Thrust ball bearings are designed for carrying Axial loads and are of separable construction, the shaft washer (ring), the housing washer(ring) and the cage-ball assembly are to be put together for use on the shaft. They are manufactured in multiple series, and as single-directional or bi-directional.
• The single-row thrust ball bearings consist of a shaft washer (ring) with an raceway, a cage with balls and a housing washer (ring) with a raceway. These bearings can transmit axial load in one direction only, and must not be exposed to radial load. The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.
• Bi-directional thrust ball bearings have two cages with balls placed between the shaft washer (ring) and two housing washers (ring). The central shaft washer (ring) has raceways for roller elements on both sides, and is mounted onto a shaft. The housing washers (ring) have the raceway on one side only. These bearings can transmit axial load in both directions. The bearings must not be exposed to radial load. The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.

Single-row tapered roller bearings are of separable construction. The inner ring is assembled with a cage and the rollers and has to be used along with the outer ring for operation. The rings are to be mounted separately on to the machine during assembly – – Inner ring on the shaft and outer ring on to the housing and then they have to be put together carefully. They are manufactured in multiple series. They feature high rigidity, reasonably low friction and the ability to transmit high radial and single-direction axial load.

The intensity of the axial load transmitted depends on the size of the contact angle. Through paired arrangement of two bearings in Back-to-Back or Face-to-Face, bi-directional axial load-carrying capacity can be achieved.

The single-row tapered roller bearings are manufactured both in metric and inch dimensions.

The bearings are manufactured with normal accuracy. However, bearings with higher running accuracy can also be supplied

Using a good quality bearing is not sufficient guarantee that the machine will run smoothly without any trouble. One needs to fit the bearing with proper mounting tool on a shaft or a good quality sleeve and housing, lubricate it with good quality lubricant like grease, protect it with good quality seals and keep a track of it’s condition during operation as well. And that is why our offerings include a Complete Shaft Solution , whereby not only the Bearings, and related Logistic as well as Technical Support, but other associated ZKL Bearing Accessories such as Sleeves, Housings, Mounting / Dismounting Tools, Grease, Bearing Condition Monitoring Tools, Seals, etc, are also marketed by us.

Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

Spherical roller thrust bearings are of separable construction, The shaft washer is assembled with the cage and a number of asymmetrical spherical rollers and has to be used along with a housing washer having sphered raceway. During mounting, the rings are to be fixed on to their respective seats – shaft washer on the shaft and housing washer on to the housing and then they have to be put together carefully They are manufactured in multiple series.

The raceway of the housing washer is at an angle with it’s ais of rotation, so as to be able to allow the rollers to remain in touch with it. As a result, a spherical roller thrust bearing is capable of carrying both a radial as well as an axial load. Spherical roller thrust bearings – because of their internal geometry – are capable of accommodating certain amount of misalignment. However, they can take axial loads only from one direction, and may need to be used in pairs in Back-to-Back or Face-to-Face arrangement, if thrust load from both the directions are to be carried.

Spherical roller thrust bearings are capable of compensating misalignment and shaft deflection.

The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.

Traditional Plain Bearing users who handle radial loads and suffer the constant tension of major and minor misalignments can now take heart.

 

The latest hi-tech addition to the wide and growing range of ZKL- Spherical Plain Bearings will handle radial loads and misalignment with smooth and effortless ease…virtually maintenance free.

 

Advantages:-
Maintenance- free ZKL spherical plain bearings boast several advantages over the rolling-element designs. For example, they do not require lubrication because of the special sliding- contact surface. The sliding layer is asymmetrical, and resistant to moisture. An adhesive bond resist separation. The bearings support high dynamic and static loads. The bearings have a low friction factor and can take high contact pressure.

Plus there are several variations to the bearing design. Spherical plain bearings are good for supporting radial loads and where bearings must work without maintenance. The design is also recommended where it’s suitable to lubricate a metallic sliding- contact surface, as in unilateral loads. The design can be combined with axial spherical plain bearings to support axial loads also.
