BS2-2218-2CS/VT143 sealed spherical roller bearings

Sealed spherical roller bearing product dimensions: B series sealed bearings are consistent with the internal design of open bearings. Except that the width of the B series sealed bearings is slightly larger than that of the 3 series bearings, the overall dimensions of the other bearings are exactly the same.
B series sealed bearings generally have cylindrical holes. But most series of bearings are provided with tapered holes. Upon special request and in certain quantities, each type of sealed bearing is also available with a tapered bore.
Sealed spherical roller bearing sealing ring:
The sealing ring is fixed in the groove of the outer ring. For smaller bearings, the sealing ring is clamped by the groove. For larger bearings, the sealing ring is fixed in the groove by a retaining ring. The sealing lip of the sealing ring contacts the edges of the raceways on both sides of the inner ring, providing effective sealing for the bearing.
Product advantages of sealed spherical roller bearings:
The purpose of bearing sealing is to prevent the leakage of lubricant in the bearing part, and to prevent external dust, moisture, foreign matter and other harmful objects from invading the inside of the bearing, causing the bearing to It can operate safely and permanently under the required conditions. The general name of the device made for this purpose is the bearing sealing device. The sealing device plays a large role in maintaining the operating performance and durability of the bearing. Grease lubrication sealing is easier, oil lubrication sealing is more difficult. The sealing device can also use sealed bearings.
