BSTB462826C Bore 200 Mm, Triple Ring Bearings For Paper Industry (controlled Crown Rolls)
The BSTB462826C The TL series spherical roller bearing are specifically designed for the drying section of paper machinery and are suitable for high-temperature, heavy-duty conditions in drying cylinder rolls, calenders, Yankee drying cylinders, and other paper processing equipment.
The BSTB462826C bearing is a Spherical roller bearings as inner and outer bearings with an inner diameter of 200 mm , an outer diameter of 520 mm, a width of 180 mm. GCr15SiMn rings, GCr15SiMn rolling mlement. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Interchange code: SKF BSTB462826C , Torrington B9484G
BSTB462826C bearings ( 200 mm x 520 mm x 180 mm) have the advantages of High temperature resistance, fracture resistance, doubled lifespan, stable and reliable, and are therefore widely used in the Paper machinery.

The BSTB462826C The TL series spherical roller bearing mainly consist of inner and outer rings, drum-shaped rollers, and a cage. The inner ring is made of special alloy steel and undergoes a carbonitriding heat treatment process. It is equipped with a heavy-duty machined brass cage (CA type) and is available in both cylindrical and tapered bore configurations, with radial clearance options ranging from C3 to C5.
The TL series spherical roller bearing exhibit significantly improved resistance to inner ring cracking, effectively solving the problem of inner ring fracture caused by high temperatures and rapid temperature rise in the drying section of paper machines. They maintain dimensional stability at temperatures up to 200°C, have high raceway surface hardness, and their lifespan is more than twice that of conventional bearings under conditions of foreign object intrusion.
