Four Row Tapered Roller Bearings
The 31300 series four row tapered roller bearings have a diameter of 139.7mm-780mm, outside diameter of 200.025mm-1220mm, and width of 157.162mm-840mm. They are made using a high carbon chromium steel GCr15, thus giving them a high hardness and outstanding erosion resistance, which makes them suitable for harsh working conditions.
Four-row tapered roller bearings are designed with two double-raceway inner rings, one double-raceway outer ring and two single-raceway outer rings, allowing them to support an extremely high radial load, axial load and impact load, and making them suitable for high speed working conditions. We can produce the four row tapered roller bearings in a variety of dimensions to meet different customer requirements.
Features
- Our bearings are made of bearing steels that have a hardness of up to HRC61-65, thus ensuring a better wear resistance.
- Between the inner ring and outer ring of the bearings, there is a space ring to adjust the clearance between the bearings, and prevent them from becoming damaged during operation. The temperature will increase if the axial clearance is too small or too large, which causes the bearings to become worn faster, and reduces the service life, which is why a space ring is added for the prevention of the temperature rise.
- These roller bearings feature an outstanding leak resistance, which prevents outer contamination, and maintains friction and heat generation at minimum levels, thus reducing maintenance costs.
