NIBL wide inner ring bearings provide easy slip fit shaft mountings and additional shaft support. These bearings feature seals with flared lips which firmly contact the ground outer diameter of the inner ring to provide a positive seal against dust, dirt and other contaminants while effectively retaining the lubricant. NIBL wide inner ring bearings have a large grease capacity. These bearings are factory pre-lubricated. Variations : Locking devices: eccentric locking collar, set-screw locking collar; inner ring extended both sides, inner ring extended one side only; Bearings with cylindrical outer diameter. Range NIBL offers wide inner ring bearings for shaft diameter between 19.05 mm to 60mm. We offer customized bearings for unique application requirements Industries Agriculture Material Handling Fluid Machinery Industrial Transmission

The rolling elements of Tapered Roller Bearings look like truncated cones. The inner ring (cone) has a special back face rib at the large cone diameter for axial load purposes. The front face rib at the smaller cone diameter together with the cage avoids dropping out of rollers. For easy mounting the outer ring (cup) has no shoulders. IBC Tapered Roller Bearings are designed for high radial and unidirectional axial loads for medium rotational speed. Generally the series 30..A, 31..A, 32..A are available. Arrangement in pairs allows for axial load in both directions. Due to contact angle Tapered Roller Bearings are intended for axial loads. Therefore a second bearing for counter guidance is necessary.

Spherical Roller Bearings are made for heavy-duty applications. They feature two rows of symmetrical barrel rollers. There are two separated raceways within the inner ring. Both roller rows are positioned in a common spherical outer ring raceway and therefore shaft deflection and misalignment at the bearing seating are compensated. They are designed for high radial and relatively high axial loads at medium rotational speed. Spherical Roller Bearings are made either with a cylindrical or with a tapered bore. IBC Spherical Roller Bearings are available in series 222.., 223.., 230.., 232.., 239.., 240.., 241.. . and are made either with steel , or with brass cages. Screen Bearings are a special version of Spherical Roller Bearings. For detailed information please refer to chapter “IBC Special Bearings”.

NIBL’s self-aligning double-row spherical roller bearings are a combination of radial and axial bearings. These are designed to operate even if shaft and housing are, or become, misaligned under load. The internal design of the spherical roller bearings enables them to withstand very high radial loads and axial loads in both directions. These type of heavy duty bearing are the preferred choice when conditions include heavy loads, difficulties in establishing or maintaining housing alignment, or when shaft deflection is expected. These bearings can take high degrees of misalignment depending on the size and series of the bearing. shaft deflection and housing distortion caused by shock or heavy loads, which lead to misalignment, are compensated for by the internal self-alignment of the bearing elements during operation. The corner loading of rollers, a condition that limits service life on other types of bearings, cannot develop in spherical roller bearings. The inherent compensation for misalignment provided by the spherical roller bearing offers the designer the opportunity to use weldments for housing frames instead of complex castings, eliminating high cost machining operations. Even when castings may be preferred, bore alignment is less critical if spherical roller bearings are specified. Unit design and construction also makes the spherical roller bearing convenient to handle during installation or maintenance. Most types have circular grooves and lubricating holes in the outer ring. This feature facilitates more effective lubrication. NIBL manufactures spherical roller bearings with cylindrical and tapered bore. Tapered bore bearings may be used either in Plummer blocks or conventional housings Range The standard NIBL spherical roller bearings are available from 22205-2228 and from 22308-22322. Bearings can be in straight or tapered bore and have clearances ranging from C2-C5.

Bearing arrangements have to be selected depending on individual application. Various factors like temperature, lubrication, rotational speed, load capacity, humidity, vibration, mounting, maintenance, etc. have to be taken into consideration. Special bearings with special features are used for special kinds of applications, for which these bearing arrangements are suitable. High performance bearings with a high degree of reliability guarantee a long service life and operational safety of the machines, plants and aggregates. For all kinds of above-mentioned bearings such as Deep Groove Ball Bearings, Angular Contact Ball Bearings, Self Aligning Ball Bearings, Thrust Ball Bearings, Cylindrical Roller Bearings, Spherical Roller Bearings, Needle Roller Bearings IBC is manufacturing special bearings for customized designs referring to outer dimensions, or special inner designs and not only standardised in ISO series.

IBC Self-Aligning Ball Bearings are of double row type, with a spherical outer ring raceway. The inner ring has two grooves similar to these of Deep Groove Ball Bearings. Their self-aligning capability allows them to compensate for misalignments. Self Aligning Ball Bearings are designed for medium up to high rotational speeds and can accommodate radial and axial loads in both directions. They are available with cylindrical or tapered bore. Bearings can be fixed on the shaft via adapter sleeve. Generally the series 12, 22, 13, 23 are available. In addition to unsealed IBC Self Aligning Ball Bearings of series 22.. and 23.., a basic design with seals on both sides can be supplied. It should be observed that the inner design of the bearings correspond to the series 12.. and 13...

This rail type completes the system RMRV.The RVA has the raceways coated with antifriction material. This type is used when the speed is relatively low (20 mmin max) and the rigid- ity of the system is critical.A set is composed of two rails RM ant two rails RVA. The rails RVA and RV are dimensionally inter- changeable. In order to have a good functioning, the temper- ature of working must be inferior to 50°. Load capacity per unit in cm 2 changes from 4500 N (dynamic) ÷ 7500 N (static). Holes and oil grooves can be carried out on request on the type RVA rail

Per le guide RMRV a rullini, valgono gli stessi criteri di calcolo usati per le guide GR. Nei riquadri a pag. 29 si possono rilevare: il dimensionamento delle gabbie e le capacità di carico relati- ve. Le guide RMRV si differiscono dai tipi GR per le seguenti caratteristiche: 1) Capacità di carico notevolmente a favore delle prime; 2) Costruzione di tavole con una elevata rigidità superiore ai tipi GR in quanto il passo dei rullini è minimo, con una conseguente maggiore continuità di rotolamento; 3) Miglior funzionamento nei casi in cui la corsa sia di piccola enti- tà in quanto un rullo di piccolo diametro riesce a lavorare su tutta la sua circonferenza.Inoltre c�è la possibilità di precari- care con più N, perché come già detto, le guide RMRV soppor- tano carichi elevatissimi ed il precarico, percentualmente, è in funzione di quest�ultimi; 4) � molto importante, ancor più che nei tipi GR a rulli incrociati, curare il sistema di protezione delle guide

The present evolution of the GR type is passing through the rea- lization of guideways that in spite of their smaller section are performing better features in respect of the carrying capacity and therefore of stiffness. This new kind of guideway named NG has two different sections whose dimensions are stated in the following page.

IBC Radial Ball Bearings are suitable for a wide variety of applications. They are suitable for high-speed applications due to low friction and are insensitive in case of operation and maintenance. The ability to carry radial as well as axial loads, they are the most commonly used bearing type. IBC Radial Ball Bearings can be supplied in a large number of sizes and designs, different cross sections covering a wide variety of applications. IBC Radial Ball Bearings are available as both side open basic design and with seals or shields at one or both sides.

CSB self-lubricating bearing is commonly used for rotating and sliding worktable parts of machine tools. It greatly cuts down the maintenance cost, prolongs service life, reduces running noise and improves working environment due to low friction coefficient, excellent wear resistance under the condition of impact load as well as self-lubricating property.
