Withdrawal Sleeves are using for mounting bearings with a tapered bore into a cylindrical seat

Tapered roller bearings are designed such that the outer ring, inner ring, and the rollers have tapered surfaces whose apexes converge at a common point on the bearing axis.

Spherical roller bearings are equipped with an outer ring with a spherical raceway surface and an inner ring which holds two rows of barrel-shaped rolling elements, spherical roller bearings are able to adjust the center alignment to handle inclination of the axle or shaft. There are varieties of bearing types that differ according to internal design. Spherical roller bearings with an inner ring with a tapered bore are denoted with suffix K. The bearing can easily be mounted on a shaft by means of an adapter or withdrawal sleeve. The bearing is capable of supporting heavy loads and is therefore often used in industrial machinery. Cages for these bearings are of both steel (CC) and brass (MB & CA) depending on the applications.

Angular contact ball bearings unite point of contact of the inner ring, ball and the outer ring runs at a certain angle (contact angle) in the radial direction. These bearings are generally designed with three contact angles and to support simultaneous radial and axial loads. Single Row Angular Contact Ball Bearing can support axial load in a single direction only and is typically paired with a second bearing for support.

Thrust bearings are classified in accordance to the rolling elements they contain and generally the allowable rotational speed is very low. Thrust ball bearing can be in single-row and double-row. Direction Thrust ball bearings and can take axial load in one direction, whereas Thrust ball bearing with double row can take axial load from both directions. Thrust bearings with rollers as rolling element can accommodate a certain amount of radial load along with axial loads.

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available to open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing

Needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The ends of the rollers are relieved slightly to modify the line contact between the rollers and raceways. This prevents stress peaks at the roller ends to extend bearing service life. In spite of their low cross section, needle roller bearings have a high load carrying capacity. Therefore, they are extremely suitable for bearing arrangements where radial space is limited.

Miniature bearings are sometimes referred to as instrumental bearings or micro bearings. These small bearings with an outside diameter less than or equal to ½” (≤12.7mm) having a ration of outside diameter to inside diameter equal to or less than two. Miniature ball bearings operate at high speeds with low friction and minimal service requirement. These bearings capable of handling light to moderate radial and thrust load. Miniature ball bearings include shield bearings and sealed bearings with grease enabling easier usage.

Linear bearings are designed to facilitate free motion in one direction. The construction of these bearings consists of a polymeric cage with raceway segments made of hardened steel to guide the ball sets within the complete system. Recirculating balls provide unlimited stroke at low friction movement.

Angular contact ball bearings unite point of contact of the inner ring, ball and the outer ring runs at a certain angle (contact angle) in the radial direction. These bearings are generally designed with three contact angles and to support simultaneous radial and axial loads. The construction of Double Row Angular Contact Ball Bearing is similar to that of a pair of single row angular contact ball bearings in an O arrangement. Owing to the raceway geometry and the two rows of balls, the bearing can support both radial and axial loads.

The most common type of bearing, deep groove ball bearings is widely used in a variety of fields. Deep groove ball bearings include shield bearings and sealed bearings with grease enabling easier usage. Deep groove ball bearings also include bearings with a locating snap-ring to facilitate positioning when mounting the outer ring. These types of bearings support’s radial load on both directions.

Cylindrical Thrust Roller Bearings are designed to high axial loads while permitting rotation between parts.

Cylindrical roller bearings use rollers for rolling elements, and therefore have a high load capacity. The rollers are guided by the ribs of the inner or outer ring. The inner and outer rings can be separated to facilitate assembly and both can be fitted with shaft or housing tightly. If there are no ribs, either the inner or the outer ring can move freely in the axial direction. Cylindrical roller bearings are of different types, like N, NU, NJ, NUP, NF depending upon the construction of inner and outer rings. Cylindrical roller bearings are designed with multiple row rollers and full compliment rollers without cage depending on the applications. These bearings are suitable for heavy radial and impact loading and are appropriate for high-speed applications.

A ball bearing unit is comprised of a ball bearing inserted into various types of housings. The housing can be bolted onto machinery and the inner ring can be easily mounted on the shaft with a set screw. This means the bearing unit can support rotating equipment without special design to allow for mounting. A variety of standardized housing shapes is available, including pillow and flange types. The outer diameter of the bearing is spherical just like the inner diameter of the housing, so it capable of aligning itself on the shaft. i. Pillow Blocks ii. Housings Plummer blocks or housing bearing units, is a pedestal used to provide support for a rotating shaft with the help of compatible. Plummer blocks housings can be used with high capacity spherical roller bearings or self-aligning ball bearings. They are made of high strength cast iron as standard and also available in cast steel. These housing have a republication facility and can be used with either oil or grease lubrication.
