Product Overview:

The 1318.KM RICH is a high-capacity, double-row self-aligning ball bearing designed for applications where significant shaft deflection or mounting misalignment is expected. This bearing features a common sphered raceway in the outer ring, allowing the two rows of balls and the inner ring to swivel freely. This unique geometry enables the bearing to successfully compensate for angular misalignments of several degrees without increasing internal friction or stress. The "KM" designation identifies the tapered bore (1:12 taper), which is typically mounted using an adapter sleeve or directly onto a tapered shaft, facilitating precise internal clearance adjustment during installation. Equipped with a premium machined brass cage for superior strength and durability in demanding conditions, the 1318.KM is an ideal solution for heavy-duty industrial machinery, pulp and paper processing equipment, and large-scale agricultural systems operating at high speeds with moderate radial loads.

Key Performance Advantages:

• Superior Misalignment Compensation: The sphered outer raceway allows the bearing to self-correct for shaft bending and assembly errors.
• High-Strength Brass Cage: The machined brass cage provides excellent resistance to impact and wear, even under high-temperature or high-vibration conditions.
• Low Heat Generation: Designed for low frictional torque, allowing for higher operating speeds while maintaining energy efficiency.
• Adjustable Mounting: The tapered bore (1:12) allows for easier mounting and dismounting when used with appropriate sleeves, ensuring optimal seating.
