What is E1 in bearing?

The FAG E1 spherical roller bearing range consists of eight se- ries. The smallest bore diameter is 20 mm and the largest out- side diameter is 320 mm. E1 spherical roller bearings are available with both cylindrical and tapered bores.

What are cylindrical roller bearings?

Cylindrical Roller bearings are designed to carry heavy radial loads and are suitable for high speed applications. The design incorporates separable inner or outer rings which simplifies assembly,dismantling, maintenance and inspection. Bore dimension range is from 15mm to 480mm.

Why choose SKF bearings?

Your local SKF distributor can help with technical, sales, and product support. Particularly versatile bearings. Suitable for high or very high speeds, accommodating both radial and axial loads in both directions. Robust, low maintenance and available in many designs.

Why choose two-row ball bearings?

These two-row ball bearings generate very little frictional heat even at high speeds – leading to minimal maintenance needs. Designed to accommodate axial loads in single or double directions. Separable and interchangeable components simplify mounting and dismounting and maintenance inspections.
