INA Cylindrical Roller Bearing

About INA Cylindrical Roller Bearing

Single row INA Cylindrical Roller Bearing with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or are without ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers coming into contact with each other during rolling.

The INA cylindrical roller bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs. Bearings with suffix E have a larger roller set and are thus designed for extremely high load carrying capacity.

The bearings can be taken apart and can therefore be fitted and dismantled more easily. Both Bearing rings can therefore have an interference fit.

Low-Friction INA Cylindrical Roller Bearings:

Low-friction cylindrical roller bearings LSL and ZSL are single row, self-retaining and correspond to dimension series 23. The bearings have solid outer rings with two ribs, while the inner rings have one rib. The inner ring can be removed and this gives easier fitting of the bearings. Disc cages or spacers prevent the cylindrical rollers coming into contact with each other during rolling.

INA High Precision Cylindrical Roller Bearings:

Cylindrical roller bearings of this type are double row precision bearings for machine tools. They allow radially rigid, high precision bearing arrangements and are mainly used for the radial support of main spindles.

The bearings comprise solid outer rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with a taper of 1:12. The cylindrical roller bearings can be dismantled and are therefore easier to fit and remove. Both bearing rings can therefore have an interference fit.

INA Full Complement Cylindrical Roller Bearings:

Full complement cylindrical roller bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.

Full complement cylindrical roller bearings are available as non-locating, semi-locating and locating bearings and in single and double row designs.

INA Cylindrical Roller Bearings with SNAP Ring Grooves:

Cylindrical roller bearings with snap ring grooves are full complement, self-retaining units comprising solid inner and outer rings, rib-guided cylindrical rollers and sealing rings.

The outer rings have grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and are held together by a steel strip that is rolled into place.

Locating Bearings:

Cylindrical roller bearings with snap ring grooves are locating bearings. These bearings are highly rigid and can support axial forces in both directions as well as high radial forces.

Due to the full complement design of these bearings, they have the largest possible number of rolling elements and thus extremely high basic dynamic and static load ratings. 

Bearings For Cable Sheaves:

Due to the grooves in the outer ring, the bearing rings can be axially located with ease. The bearings are therefore very suitable in bearing arrangements for cable sheaves.

Reliable Performance in Demanding Conditions

Designed for heavy-duty use, this cylindrical roller bearing excels in applications requiring robust load support and high speed. Its chrome steel construction and steel cage provide enhanced strength and durability, while the open design aids in efficient heat dissipation, making it ideal for both automotive and industrial machinery sectors.


Precision Engineering and Versatile Compatibility

With precision ratings of P0 and P6, the INA roller bearing offers versatility to meet varying accuracy requirements. Its single row, cylindrical structure allows for high radial load capacity, supporting critical machinery functions while maintaining smooth motion and reliability in operation.
