Double Spherical Roller Bearings from us consists of a plain bearing, with a ball pushing, inside a cylindrical housing. These cylindrical housing may have a liner manufactured from different material which minimizes friction or provides self lubrication. For different load capacity and lubrication requirement many balls or linear materials are available. These spherical bearings are maintenance free and are suitable for applications that involve swivel movement, high alternating loads, very high radial loads with a unilateral load direction and high shock loads.

Physical Characteristics

Large bores More contact area Inner rings to resist cracking Allowance for static or dynamic misalignment Expansion capabilities

We offer Sealed Spherical Roller Bearings that are used in case of heavy loads an other unfavorable conditions. The seal consists of two washers, each attached to the inner and the outer ring. The washer acts as a flinger when the inner washer rotates. The sealed bearings may have cylindrical or tapered bores. They are also manufactured for vibrating screens or exciters which induce accelerations of rollers and cages in the bearings.

Spherical roller bearings Specifications & Standards

Dimensions - Boundary dimensions in accordance with ISO Tolerance - They are usually meant for normal tolerance but can be enhanced.

Standard Cage Types: These bearings are available in cages. The pressed cages are standard for small size bearings and the machined cages are for the large ones. Newly developed glass fiber cage is used as a standard for the "E" type bearing. The glass fiber reinforced polyamide 46 resin, it has excellent heat resistance qualities (have operating temperature up to 150°C), strength as well as are oil resistance. A standard cage may not be able to be used for high- speed specifications, in conditions like high temperatures or excessive vibration/impact conditions.

Allowable Misalignment - The allowable misalignment angle varies according to dimension , series & load conditions. The standard allowable misalignment are:

Normal load (loads equivalent to 0.09 Cr): 0.009rad (0.5°)

Light load: 0.035rad (2°)

Internal Clearance - Spherical Roller Bearings meet the standard with normal radial internal clearance and are also available with a greater C3 clearance.

We manufacture spherical roller thrust bearings that are used in the steel industry. These bearings are available in various types like the tapered bore, sealing, various grease types and mounting arrangements. The spherical bearings adjust the center alignment to handle inclination of the axial or shaft. It has two rings, the outer, which has a spherical raceway and the inner ring which holds two rows of the barrel- shaped rolling elements. These bearings can easily be mounted on a shaft with the help of an adapter or withdrawal sleeve.

These bearings have high load supporting capacity and hence are used in industrial machinery. When heavy axial load is applied to the bearing, the load on rollers of another row is disappeared, and can cause problems. The spherical roller bearings have self-aligning properties and hence can be used where misalignment between the inner & outer rings occurs from housing installation error or shaft flexure. The roller bearings have a large capacity for axial loads in either direction, radial loads & complex loads. Tapered bores can also be availed from us in specifications like an attached suffix "K" to the end of the bearing's basic number. The standard taper ratio for bearings with a "K" suffix is 1:12, but for bearings in series 240 and 241 the suffix "K30" indicates the taper ratio for a bearing is 1:30. Several tapered bore bearings make the use of adapters and withdrawal sleeves for shaft mounting.
