E Type Spherical Roller Bearings

E Type Spherical Roller BearingsE-type spherical roller bearings are an "Extra" capacity design of spherical roller bearings. This design has now surpassed the standard load rating capacity resulting in a better life. As a result, the E design's improved price/performance ratio results in overall reduced TCO (Total Cost of Ownership) for customers. E-type spherical roller bearings have two stamped window-type steel cages, an inner ring without flanges, and a guide ring centered on the inner circle (d>65 mm) or the cages (d >65 mm). They have an annular groove and three lubrication holes in the outer ring.

Series of E-type Spherical Roller Bearings

Here are some popular types of E-type spherical roller bearings:

• 22206 E
• 22309 EK
• 22308 E

Features of E-type Spherical Roller Bearings

E design bearings are indicated by the designation suffix E. All E design bearings have an optimized internal design for increased load-carrying capacity. The middle retaining ring close to the outer ring can improve the lubrication of the contact between the roller end face and the retaining ring. Its role is to reduce bearing friction, help guide the roller in the non-load area, and help the roller enter the load area. The length of the sub is increased, so the rated load has been dramatically improved. The usually rated load can be increased by 20% to 35%. E-type spherical roller bearings have exceptionally high load capacity, low torque, and a high-strength cage.

Applications of E type Spherical Roller Bearing

E-type spherical roller bearings are widely used in Gearbox, Wind Turbines, Pumps, Fans and blowers, Mining equipment and construction machinery, Pulp, and paper processing equipment, Ship and offshore equipment, Metallurgical industry equipment, Railway axle boxes, and so on.
