Radial insert ball bearings are single row, rady-to-fit units comprising a solid outer ring, an inner ring extended on one or both sides, cages made from plastic or sheet steel and P, R, L or T seals. Bearings with an inner ring extended on both sides undergo less tilting of the inner ring and therefore run more smoothly.
The outer ring has a crowned or cylindrical outside surface. In conjunction with an INA housing matched to the bearing type, bearings with a crowned outside surface compensate for shaft misalignments; see Compensation of misalignments.
They are located on the shaft by means of an eccentric locking collar, grub screws in the inner ring, an adapter sleeve, drive slot or fit. Radial insert ball bearings are particularly easy to fit, suitable for drawn shafts of grade h6 to h9 and, with a few exceptions, can be relubricated.
Some series with an eccentric locking collar and with grub screws in the inner ring are also available with an inch size bore.

FAG housing and bearing units have successfully been used in machinery, installations and equipment.
FAG bearing housings are usually made of greycast iron.
As a rule, the bearing seats in the housings are machined in such a way that the bearings can be
displaced, i.e. they are of the floating type. All outer surfaces of FAG housings and housing parts are provided with a universal coat of paint (colour RAL 7031, bluish grey).
Depending on the operating conditions, the bearing housings can be sealed with rubbing seals, non-rubbing seals, and combinations of both.

RKB multi row bearings have low cross section, high load carrying capacity, stiffness and are used for metal rolling equipment in mills.
They are of separable design that considerably simplifies mounting, maintenance and inspection.
They can tolerate moderate to high shaft speeds. The rollers and outer races are carefully matched to ensure the best load distribution.
Inner rings (designation L) are interchangeable with other assemblies (designation R).
They have cylindrical bore and some sizes are also available with tapered bore.
The use of them in metal rolling mills exposes them to very heavy stresses.The rings and rollers can be manufactured with very high quality case hardened carburizing alloy steels. Deep case depth and special heat treatment ensure superior size stability, fracture toughness and reliability.
Where the bearings are mounted with a loose fit on the roll neck, RKB multi row cylindrical roller bearings have C2 internal radial clearance and are supplied with a helical groove in the bore and/or lubrication grooves in the side faces of the bearing rings for the efficient lubrication (e.g. suffix AC).
RKB produces the multi-row cylindrical roller bearings in several construction.
The various designs differ basically in the number of inner and outer rings, in the number of loose or integral flanges on the outer ring, in the cage type, and in the number of rollers in the cage pocket.
Furthermore, on order, RKB can produce the bearings sealed at both sides by radial rubbing seals or with wider inner ring.
They are produced with the normal precision grade for roll neck bearings, conform to class P6 for dimensional and running accuracy to ISO 492.

Stainless steel bearing units are used, amongst others, in sectors featuring high-component corrosion resistance requirements.
In these sectors characterised by demanding operating conditions (such as high relative humidity or direct contact with aggressive environments), the conventional grey iron self-aligning bearing units are no longer suitable and will not fully meet the requirements.
To satisfy the specific operating requirements, SNR proposes an extensive standard programme of stainless steel self-aligning bearing units, which also meets the USDA H1 standard criteria dictated by the pharmaceutical and agri-food industries (notably, the high-purity level of lubricant constituents), as all SNR stainless steel self-aligning bearings are exclusively filled with a grease complying with this specification.

SNR has developed a specific thermoplastic bearing units range offering decisive advantages to the users.
SNR thermoplastic self-aligning bearing units are designed for extreme condition operations, sometimes combining high loads, extreme temperatures, vibrations, corrosion and misalignment. In fact, our bearing units are fitted with seals and deflector baffles, as well as corrosion-resistant, pre-lubricated stainless steel rings and rolling bodies.
All our thermoplastic bearing units are lubricated with USDA H1 standard-approved greases. This standard involves the most stringent requirements in terms of hygiene and purity of the grease constituents or raw materials.
Of white colour PBT design, these bearing units feature a smooth surface preventing dust entrapment or fungus and bacteria development. For lubrication, SNR has designed an odourless, tasteless agri-food-compatible grease, harmless to food products.

Track rollers for Vee bars/Plain rollers - type FR/LR
The backlash setting and the pre-tensioning of the rollers takes place via the eccentric hub of the rollers of the series FR.., FR..R or LR.., LR..R.
The FR..Z and LR..Z series are the concentric models. In the eccentric rollers, the inner bolts are provided with two holes. These allow for the adjustment of the backlash. If a roller is located in its zero position, the teeth backlash will be the standard value of 0.05 mm flank clearance.
The service life of the system will be reduced by excessive tensioning. With too little tension the rollers will not run, or will wear due to the poor meshing.

Four-row and six-row cylindrical roller bearings are used almost exclusively in the metal industry. Their friction is relatively low when compared with other roller bearings. As they are normally mounted with an interference fit on the roll neck, they are particularly suitable for rolling mill applications where the rolling speed is high.
Since very many rollers can be incorporated, the radial load carrying capacity is exceptionally high. Multi-row cylindrical roller bearings are unable to accommodate axial loads but they can be mounted together with deep groove or angular contact ball bearings or with tapered roller bearings to help accommodate any axial loads.
