Deep groove ball bearings are the most common type of ball bearings and are used in a wide variety of applications. They have a simple design, are non-separable and well-suited for high and very high speeds and are robust in operation, requiring very little or no maintenance. In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated. They commonly feature pressed steel cages. However, for big deep groove ball bearings machined brass cages are used.

Self-aligning ball bearings are recommended when alignment of the shaft and housing poses difficulty. These bearings have two rows of balls and a common sphered raceway in the outer ring. The bearings generate less friction than other types of rolling bearings, hence enabling them to run cooler even at high speeds. Pressed steel cages are most widely used in this type of bearings. Some series of the self-aligning ball bearings are available with seals.

Following types of self-aligning ball bearings designs are available:

• Basic design bearings
• Bearings with an extended inner ring
• Sealed bearings

Applications

Cylindrical roller thrust bearings contain cylindrical rollers. They can accommodate only axial loads, but they are suitable for heavy loads and have high axial rigidity. Furthermore, they are relatively insensitive to shock loads. The cages are machined brass. Normally these bearings can transmit axial loads in one direction. Cylindrical roller thrust bearings are very simple in design. The surface of the rollers is changed slightly and curved at its ends. These bearings are separable, hence individual components can be installed independently.

Applications:

• Gearboxes
• Crane Hooks
• Oil Well Swivels
• Cone Pumps
• Winch Systems

Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis.

Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. They are perfectly suited to accommodating combined loads. The ability of the bearing to transfer axial load largely depends on the contact angle. The larger the angle, the greater the bearing’s ability to sustain axial load. Tapered roller bearings generally have a separable design. Tapered roller bearings provide various important and unique performance characteristics to meet a wide range of application requirements.

Adapter sleeves are used to locate bearings with tapered bore on plain or stepped shafts. They facilitate bearing mounting and dismounting and, in many cases, simplify bearing arrangement design.

• Withdrawal Sleeves

Withdrawal sleeves can be used to mount bearings with a tapered bore on the cylindrical seat of stepped shafts.

We offer a comprehensive assortment of bearing housings in a variety of designs, sizes, material, and brands.
