How to use spherical roller bearings?

Spherical roller bearings are suitable for occasions where angle errors are caused by installation errors or shaft deflections. In addition to bearing radial load, the bearing can also bear axial load acting in both directions.

What are the structural types of spherical roller bearings?

Spherical roller bearings are divided into cylindrical bore, conical bore. The taper of the tapered inner hole is 1:12 for the rear-mounted spherical roller bearing (type 153000 or 113000) with the rear code K30 and the 1:30 rear-mounted spherical roller bearing with the code name K30. When this type of bearing is matched with a conical shaft, the radial clearance of the bearing can be adjusted by moving the inner ring in the axial direction.

What are the main uses of spherical roller bearings?

Applicable cage for main spherical roller bearing: stamped steel plate reinforced cage (suffix E). Stamped steel plate cage (suffix CC), glass fiber reinforced polyamide 66 cages (suffix TVPB), machined brass two-piece cage (suffix MB). Machined brass integral cage (suffix CA), stamped steel cage for vibration applications (suffix JPA). Brass cage (suffix EMA) for vibration applications. For the same structure, the code on the bearing may be different.

Main uses of spherical roller bearings: papermaking machinery, reduction gears, railway vehicle axles, rolling mill gearbox bearing housings, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical Self-aligning bearing with seat.

What are the correct use steps for spherical roller bearings?

For self-aligning spherical roller bearings, the use of an intermediate mounting ring can prevent the outer ring from tilting and rotating when the bearing with shaft is installed in the shaft hole of the case. It should be remembered that some sizes of self-aligning ball bearings have balls that protrude out of the sides of the bearing, so the middle mounting ring should be recessed to prevent damage to the balls. A large number of bearings are generally installed mechanically or hydraulically.

For separable spherical roller bearings, the inner ring and outer ring can be installed separately, which simplifies the installation process, especially when the inner and outer rings need an interference fit. When installing the shaft with the inner ring in place into the bearing housing including the outer ring, you must pay attention to check whether the inner and outer rings are correctly aligned to avoid scratching the bearing raceway and rolling parts. Mounting sleeves are recommended for cylindrical and needle roller bearings with inner rings without flange rib or inner rings with flange on one side. The outer diameter of the sleeve should be equal to the inner ring raceway diameter F, and the machining tolerance standard should be d10. Drawn cup needle roller bearings are best mounted with mandrels.

Due to the increasing demand for spherical roller bearings, the types of spherical roller bearings have also been developed a lot. More and more different types of excavators are widely used in all aspects of people's production and life.
