23138-E1-XL-TVPB

The 23138-E1-XL-TVPB Spherical Roller Bearing is a high-end component engineered to withstand extreme radial and combined loads while reliably managing shaft deflection and mounting misalignment. As a double-row spherical roller bearing, it features a concave outer ring raceway that allows the inner ring and roller assembly to swivel, which is crucial in applications prone to non-perfect alignment. The suffix -E1 denotes an optimized internal design for increased load capacity, offering superior performance compared to standard versions. The core dimensions are 190 mm bore, 320 mm outside diameter, and 104 mm width, making it a robust solution for large machinery in demanding industries.

This particular bearing model incorporates several advanced features for enhanced operational life. The -XL designation indicates an "X-life" quality product, a premium performance standard that signifies improved running accuracy, extended service life, and higher dynamic and static load ratings-typically over 1610 kN and 2220 kN, respectively. The -TVPB suffix specifies a glass fibre-reinforced polyamide cage, which is lightweight and offers excellent sliding properties and low friction, resulting in cooler, quieter operation at higher speeds (limiting speed up to 2070 r/min). This blend of high-capacity design, self-aligning capability, and premium material construction makes the 23138-E1-XL-TVPB an ideal choice for heavy machinery like paper mills, continuous casting machines, and large fans.
