FAG spherical roller bearings E1 Higher cost-effectiveness and operational security with X-life · Advantages Higher cost-effectiveness and operational security with X-life FAG spherical roller bearings have proved highly effective wherever high loads are present and there is a need to compensate for shaft deflections and/or misalignment of bearing seats. The previous designs of spherical roller bearings were already characterised by high performance capacity. This has now been surpassed to a significant degree by FAG spherical roller bearings E1 developed in accordance with the X-life...

FAG spherical roller bearings E1 The range The range The range of FAG spherical roller bearings E1 comprises eight series. The smallest bore diameter is 20 mm, the largest outside diameter is 1 220 mm. Narrow bearings with a low crosssection, for example of series 230, allow high speeds and require little mounting space. In contrast, wide bearings with a high cross-section, for example of series 223, have a very high load carrying capacity. We supply spherical roller bearings E1 both with a cylindrical and with a tapered bore. As a result, there are several options for locating the bearings...

Features of spherical roller bearings E1 Basic designs · Angular adjustment facility · Tolerances Features of spherical roller bearings E1 FAG spherical roller bearings E1 are bearings for the heaviest loads. They contain two rows of symmetrical barrel rollers which orient themselves freely in the concave outer ring raceway. As a result, shaft flexing and misalignment of the bearing seats are freely compensated. Spherical roller bearings E1 have a very large number of rollers with a large diameter and long length. Due to the narrow osculation between the rollers and raceways, uniform stress...

Features of spherical roller bearings E1 Internal clearance Internal clearance In the basic design, spherical roller bearings are produced to the clearance group CN (“normal”) (without a suffix for the internal clearance). In order to take account of the different operating and mounting conditions, we can also supply bearings with a larger radial internal clearance by arrangement. The suffixes are C3 for a radial internal clearance larger than CN and C4 for a radial internal clearance larger than C3. The values for the radial internal clearance of spherical roller bearings with cylindrical...

Features of spherical roller bearings E1 Lubrication groove · Speed suitability · Operating temperature limit · Tapered bore Lubrication groove, lubrication holes In order to simplify lubrication, FAG spherical roller bearings E1 have a circumferential groove and three lubrication holes in the outer ring, except for bearings of series 213..-E1 up to a bore diameter of 35 mm. In all bearings of the E1 design, no suffix is used for the design with a lubrication groove and lubrication holes. Tapered bore FAG spherical roller bearings of most series are also supplied with a tapered bore. The...

Features of spherical roller bearings El Spherical roller bearings El without a cage suffix have sheet steel cages. The two cage halves are retained by a guiding ring in the outer or inner ring. With the exception of the series < 20), all sheet cages in the basic are protected in particular against wear by surface hardening or coating. Spherical roller bearings E1A with solid brass cages are indicated by Spherical roller bearings E1A with an outside diameter of more than 460 mm have single-piece solid brass cages (MB1) guided on the inner ring. Bearings with an outside are available by...

Features of spherical roller bearings E1 Equivalent load · Minimum radial load · Axial load carrying capacity · Vertical shaft arrangement · Mounting dimensions Axial load carrying capacity Equivalent dynamic load P = Fr + Y1 · Fa The values Y 1 , Y 2 and e are given in the bearing tables. Mounting dimensions FAG spherical roller bearings are also suitable for high axial loads. If very high loads occur in combination with very high speeds, however, the increased friction and bearing temperature must be taken into consideration. Information on this point is available from our technical...

Features of spherical roller bearings E1 Suffixes Common combinations of suffixes: Increased capacity design Tapered bore, taper 1:12 Tapered bore, taper 1:30 Solid brass cage, guided on rollers Solid brass cage, guided on inner ring Solid window cage made from glass fibre reinforced polyamide, guided on inner ring Special design for oscillating load with restricted tolerances, radial internal clearance C4 Special design for oscillating load with restricted tolerances, radial internal clearance C4, bore with thin layer chromium plating Increased capacity design, tapered bore (taper 1:12)...

Accessories · Products for mounting, maintenance and monitoring Accessories FAG spherical roller bearings E1, in conjunction with FAG fasteners and housings as well as FAG Arcanol rolling bearing greases, form units whose components are optimally matched to each other. FAG adapter sleeves and withdrawal sleeves greatly simplify the mounting and dismounting of spherical roller bearings with a tapered bore. Locknuts are used to locate spherical roller bearings E1 directly on the shaft or on an adapter sleeve. Locknuts can also be used in the mounting and dismounting of bearings on withdrawal...
