Sealed spherical roller bearings

In addition to general open bearings, Spherical roller bearings can also provide customers with closed structure bearings with sealing rings on both sides. The sealing rings can be divided into contact or non-contact (low friction) according to the contact form.

Bearings with sealing rings on both sides are filled with grease before leaving the factory, and the amount of grease filled is generally 25% to 35% of the effective space in the bearing. Bearings with sealing rings on both sides should not be cleaned or heated above 80°C during installation. Otherwise, the bearings will be easily damaged or the grease will be degraded and lost. Bearings with seals can maintain their proper performance in the ambient temperature range of 30℃~+100℃.
